Every industrial success story has a starting point, and for DEE Development Engineers Ltd (DDEL), that point was 1983, when Krishan Lalit Bansal set up a small Engineering Design Consultancy firm in Delhi. At the time, India’s power and oil & gas sectors were largely dependent on imported process-piping systems and foreign engineering expertise for technically demanding applications – high-pressure piping, induction bends, and engineered fittings for boilers, refineries and petrochemical plants. Bansal bet that India’s industrial capex cycle would eventually need a domestic, design-led manufacturing partner capable of executing complex piping systems end to end, rather than a job-work fabricator executing someone else’s drawings.
Forty-three years on, that bet has paid off in ways few could have predicted. The company started its manufacturing journey in 1988 from a single process piping unit at Palwal, Haryana. Today, DDEL is among the top five players globally by installed process-piping capacity and India’s largest process-piping company by installed capacity – a claim it backs with seven manufacturing facilities across Haryana, Gujarat, Assam and Thailand, supported by an engineering division in Chennai. The Faridabad-headquartered company listed on the BSE and NSE in June 2024, formalising its transition from a promoter-led manufacturer into a publicly listed, institutionally owned platform. A workforce of more than 1,100 employees underpins a manufacturing base recognised globally for quality and reliability, living up to what Bansal calls the company’s tagline: “Make every customer a repeat customer.”
Focus on core verticals
DDEL, which has traditionally catered to the power and oil & gas sectors, is now looking to deepen its presence in these core verticals while foraying into newer, high-growth areas such as nuclear piping, data centres and semiconductors. With an order book of around Rs2,436 crore as of August 2026 and a total installed capacity of 125,900 MT per annum across piping and heavy fabrication, the company has also backward integrated into thick-walled seamless pipe manufacturing at its Anjar facility in Gujarat – India’s first such plant – reducing its historical dependence on imports for high-specification power-sector piping.
The company is targeting a topline of around Rs2,500 crore by FY30, up from about Rs1,142 crore in FY26. Its customer base includes marquee domestic and global names such as Reliance Industries, JGC Corporation, Nooter Eriksen, MAN Energy Solutions, John Cockerill, HPCL-Mittal Energy, Toshiba JSW and Mitsubishi Heavy Industries. Exports have historically contributed close to 50 per cent of revenue across more than 27 countries, and management expects a broadly similar mix going forward, even as domestic power-sector orders scale up.
“Our longer-term ambitions are set out in the Vision 2030 roadmap. Under Vision 2030, we are targeting over Rs2,500 crore in revenue, driven by disciplined capital allocation, capacity utilisation and margin expansion, building a stronger, more resilient company for our shareholders and stakeholders,” says Bansal, 71, Chairman and Managing Director, DDEL. A mechanical engineer from Punjab Engineering College, Chandigarh, he founded the company in 1988 and has spent nearly four decades growing it into a major name in prefabricated piping systems.
“We have a very clear vision that we have to have the nuclear sector in our fold in the next 2 years, and we are equally targeting data centres and semiconductors as new growth avenues. At the same time, our seamless pipe plant at Anjar – India’s first – strengthens backward integration, reduces import dependence, and will meaningfully support margins and product integration as utilisation ramps up.”
At its core, DDEL is a design-led, one-stop engineering, procurement, manufacturing and supply (EPMS) platform for complex industrial piping and heavy fabrication. It has evolved from being purely an engineering consultancy into a business that designs, procures raw materials, manufactures, tests and delivers ready-to-install piping systems and heavy fabricated equipment to some of the world’s most demanding industrial customers.
An array of offerings
Its offerings span ready-to-install piping spools; industrial pipe fittings and induction pipe bends, which are safety-critical in high-pressure systems; heavy fabrication – including wind-turbine towers and industrial stacks up to 140 metres, executed through subsidiary DEE Fabricom India at Anjar; modular piping skids assembled off-site; and pressure vessels, PSA gas plants and industrial gas piping. On the non-core side, the company runs two biomass power plants at Abohar (8 MW) and Muktsar (6 MW) in Punjab, complemented since Q1 FY27 by a 72,000 MTPA biomass pellet facility.
This is backed by deep engineering capability – layout engineering, 3D modelling, stress analysis and isometric generation, followed by pre-fabrication (CNC bevelling, robotic welding) and advanced non-destructive examination – covering the entire chain from a blank drawing to a tested, dispatch-ready pipe spool. Its certification stack, including ISO 9001:2015, ISO 3834-2, ISO 45001, PED Module H and ASME ‘U’/’U2’ stamps, is a credential wall that keeps out all but a handful of global competitors.
Ask Bansal what differentiates DDEL from the crowd of process-piping fabricators in India, and a few themes recur. “DDEL has built a proven track record of 38 years in specialised process-piping solutions, and today we are amongst the top five players in the world by installed process-piping capacity. In India, we have practically no competition except one or two players with significantly lower capacity; internationally, our competition is broadly limited to Korean and Turkish players. What truly sets us apart is our backward integration through the seamless pipe plant, a very special facility meant only for very high-wall, large-diameter pipes that most suppliers simply cannot offer,” he says.
That scale – 93,500 MTPA of piping capacity and 32,400 MTPA of heavy-fabrication capacity, giving a combined 125,900 MT annually across India and Thailand – is a genuine competitive edge.
The second differentiator is metallurgical depth. “Our strength lies in handling the most demanding metallurgy in the industry – carbon steel, stainless steel, super duplex stainless steel, alloy steel, and high-performance materials such as Inconel and Hastelloy. With our seamless pipe plant, we are now manufacturing high-wall-thickness P91 and P92 grade pipes in-house for the first time in India – a segment that was 100 per cent import-dependent earlier,” Bansal notes. This expertise matters enormously in mission-critical sectors such as nuclear, LNG and high-temperature power, where material failure is not an option.
The third is automation – robotic welding, CNC bevelling, high-frequency induction bending and digital radiography – enabling DDEL to compete on quality and turnaround rather than simply on labour costs.
The fourth, and increasingly the most important, is backward integration. Thick-walled seamless pipes used in supercritical coal-fired boilers (P91/P92 grade for 660 MW and 800 MW units) were historically 100 per cent import-dependent in India, sourced largely from China and Europe. DDEL’s decision to build India’s first seamless pipe plant at Anjar changes that – a structural, multiyear margin lever rather than a one-off capacity addition.
If Palwal was where the company was built, Anjar in Gujarat is where its future is being built. Strategically located near the Kandla and Mundra ports, the Anjar campus has grown into a cluster of four facilities: the Support & Structure Fabrication Unit (3,000 MT), the Heavy Fabrication Unit (32,400 MT), the Pipe Fabrication Unit (30,000 MT, scaled up from 6,000 MT and commissioned ahead of schedule during FY26), and the new Seamless Plant (7,000 MTPA).
“Anjar is our modern, port-proximate manufacturing hub – home to India’s first seamless pipe plant – and, as utilisation ramps up, it will meaningfully strengthen our execution capacity and margins over time,” Bansal says.
The seamless plant is the centrepiece of the company’s backward-integration strategy – “primarily meant for coal-fired boilers of 800 MW, 660 MW and above,” since it produces high-wall-thickness pipe that HRSG applications typically do not require. Bansal expects the unit to earn “at least around 20 per cent EBITDA” on a standalone basis, with roughly half its output consumed captively and the other half sold externally to customers such as L&T and BHEL. The company has already secured an independent seamless-pipe order worth around Rs68 crore from L&T, alongside a Rs200 crore BHEL order in which its own seamless pipe is expected to contribute Rs80-90 crore of value.
Anjar is not just adding tonnage – it is designed to capture value that previously flowed to foreign suppliers. Its U-shaped layout enables efficient material handling, while proximity to ports reduces transport costs and transit times. Management has guided that the Anjar facility – which houses both fabrication and seamless-pipe capacity – is on track to ramp up from around 50 per cent utilisation to roughly 60-65 per cent in FY27, with a path to near-full utilisation by FY29, at which point the facility alone could generate as much as Rs1,500 crore in revenue.
Beyond Anjar and the original Palwal campus (three units, with a combined capacity of 36,000 MT), DDEL operates a pipe-fabrication unit in Numaligarh, Assam (6,000 MT), an engineering division in Chennai, and an international facility in Bangkok, Thailand (14,500 MTPA) – management’s ‘showcase unit’. That plant, executing largely on a job-work basis for customers such as Nooter Eriksen and global OEMs for gas-turbine and HRSG (Heat Recovery Steam Generator) piping, is now, in Bansal’s words, “practically 100 per cent booked for the coming three years,” reflecting surging global gas-turbine order backlogs at GE, Siemens and Mitsubishi, driven by data-centre-led growth in electricity demand.
Rounding out the network are the two Punjab biomass power plants, which the company is reshaping by pivoting from pure power generation towards biomass-pellet manufacturing, redeploying the same agricultural-residue fuel supply into a higher-margin product with minimal incremental capital.
Power-packed order book
For most of its history, DDEL’s order book has been anchored by power (thermal boilers, HRSG systems and now nuclear) and oil & gas (refineries, petrochemicals and LNG). As of Q1 FY27, process-piping solutions accounted for 93 per cent of the Rs2,428.20 crore order book, with heavy fabrication contributing seven per cent. That concentration has served the company well through India’s capex upcycle, but management is now working to widen the aperture.
The most significant new frontier is nuclear. The company has “a very clear vision that we have to have the nuclear sector in our fold in the next 2 years”, Bansal says, adding that it is “quite near to meeting that target”, with advanced discussions under way to onboard a strategic partner to meet pre-qualification requirements for export markets, while pursuing domestic projects on DDEL’s own strength. Value addition in nuclear piping, he notes, “is much more than in the power sector”, reflecting stricter material, welding and traceability standards.
Alongside nuclear, the company is targeting data centres and semiconductor fabrication, where per-project piping tonnage is smaller than that of a power plant, but the scale of global capex committed – well over a trillion dollars in data-centre investment worldwide – represents a substantial emerging market. The company is also eyeing fertiliser-sector piping following new government-backed plant announcements, including a proposed project in Assam.
This diversification does not mean DDEL is moving away from its traditional strengths – it is deepening its presence in power and oil & gas even as it expands into new verticals, as evidenced by its Rs386.82 crore purchase order from Bharat Petroleum, described as “one of the largest single orders in our recent history.” On the power side, the company has signed an MoU with Siemens for continuous gas-turbine piping business, beginning with roughly 10 units in the coming year and scaling up to 25-30 units by the third year, while continuing to receive orders from GE and expanding relationships with Nooter Eriksen and Mitsubishi.
DDEL has built a proven track record of 38 years in specialised process-piping solutions, and today we are amongst the top five players in the world by installed process-piping capacity
DDEL’s financial trajectory reflects a company moving from a capex-heavy build phase into one focused on execution and utilisation. Revenue from operations grew from Rs827 crore in FY25 to Rs1,142 crore in FY26 – an increase of 38 per cent – while operating EBITDA rose by 53-55 per cent to around Rs189-191 crore, lifting the margin to about 16.7 per cent. PAT grew 77 per cent to Rs77.2 crore, and the closing order book expanded by 58 per cent to Rs1,940 crore as of 31 March 2026.
That momentum carried into FY27. Q1 revenue stood at Rs294.5 crore, up 31.6 per cent year on year, with operating EBITDA of Rs49.7 crore (up 38.7 per cent, margin 16.9 per cent) and PAT of Rs16.1 crore (up 22.4 per cent). Management noted that around Rs25 crore of dispatches were deferred into Q2 because of geopolitical disruptions in the Middle East, even though the material was, in Bansal’s words, “fully manufactured, packed, and ready for dispatch.” Adjusting for that, he says, “our underlying performance in Q1 is on track, and we remain firmly on track to deliver our revenue guidance for the year.”
Committed to topline growth
“With the majority of our planned expansion capex now behind us, our focus has shifted towards improving capacity utilisation, driving higher asset turns, expanding margins, and generating stronger operating cash flows. We remain firmly committed to a topline of more than Rs1,500 crore this year, with an EBITDA margin above 19 per cent, without any doubt,” Bansal says, calling these “the bare minimum numbers which must be there on our top line” rather than a stretch target, and expressing confidence that the company can exceed them, given the pipeline across BHEL, L&T, JSW and export customers.
A capex-heavy build phase inevitably brings leverage, and DDEL has used FY27 to address that directly. In July 2026, it completed a Rs300 crore preferential issue at Rs502 per share, anchored by institutional names including WhiteOak, Kotak, 360 ONE and ValueQuest, alongside promoter participation. Of the roughly Rs293 crore in net proceeds, around Rs225 crore has been earmarked for debt repayment, with the balance allocated to general corporate purposes. The company expects net debt to fall from around Rs733 crore at the close of FY26 to Rs 400-425 crore by the end of FY27.
“The proceeds earmarked for debt repayment are expected to materially reduce leverage and finance costs, improve return ratios, and provide us with greater financial flexibility to pursue future growth opportunities while maintaining a disciplined capital structure,” says Bansal.
Our longer-term ambitions are set out in the Vision 2030 roadmap. Under Vision 2030, we are targeting over Rs2,500 crore in revenue
DDEL’s Vision 2030 targets revenue of more than Rs2,500 crore, with an EBITDA margin above 19 per cent and PAT reaching 9-10 per cent of revenue by FY30. The company’s own trajectory maps a path from Rs827 crore in FY25 to Rs1,500 crore in FY27, Rs1,800 crore in FY28, and Rs2,500 crore by FY30 – implying a revenue CAGR of roughly 22 per cent, an EBITDA CAGR of around 26 per cent, and a PAT CAGR of around 30 per cent. Bansal has suggested that the target could be achieved sooner: “We are targeting Rs2,500 crore. Although we have said FY30, we are trying to achieve it in FY29.”
That confidence rests on three pillars: a supportive domestic capex cycle across thermal power, refining expansion and export demand; margin levers from the seamless pipe mill, port-proximity logistics and automation; and optionality in nuclear, data centres, semiconductors and green hydrogen – upside that management has deliberately not built into its base-case projections.
All in all, DDEL has come a long way. From a single workshop established in Faridabad in 1988 to a listed, multi-geography manufacturing platform spanning seven facilities across India and Thailand, the company has steadily transformed itself from a piping contractor into an integrated, design-led engineering and manufacturing powerhouse. Having built its reputation on deep execution capabilities in the power and oil & gas sectors, the company is now backward-integrating into thick-walled seamless pipe manufacturing at Anjar while broadening its horizons into nuclear piping, data centres and semiconductors, without diluting its focus on its traditional strongholds.
With a robust order book of around Rs2,436 crore, a strengthened balance sheet following its recent preferential issue, and a clear roadmap to scale revenue to around R 2,500 crore by FY30, DDEL appears well positioned to convert India’s ongoing capex upcycle – and its own three-decade engineering legacy – into the next phase of sustainable, profitable growth.
