Pipes, Pressure, and a Power Plant That Forgot How to Make Money

The Quietly Ambitious Pipe Dream Finally Waking Up

Meet DEE Development Engineers — incorporated in 1988 in Palwal, Haryana, doing something that sounds monumentally unsexy: fabricating pipes. Not regular pipes your plumber wrestles with on a Sunday afternoon. We’re talking complex alloy steel pressure piping systems, process piping solutions, heat exchangers, and modular skids for power plants, oil refineries, petrochemical complexes, and nuclear facilities.

If Castrol is the boring cash machine, DEE is the loud construction worker who just got a promotion and is still figuring out whether to buy a car or pay off debt. Revenue is growing at 36% TTM. PAT grew 251% TTM. EBITDA swung 666% in a single quarter. These are not calm, measured, “value investor approved” numbers — these are “hold on to your hard hat” numbers.

The company went public in June 2024, raised ₹325 Cr, used the proceeds to clean up its balance sheet (gearing went from 1.13x to 0.72x), and then promptly started spending again on a seamless pipe plant and facility expansions. The growth CAPEX cycle is now “95–98% complete” per management — which means the margin expansion story is just beginning.

But it’s not all sunshine and scaffolding. The biomass power division — a side business that generates electricity for Punjab’s state grid — had its tariff slashed from ₹8.57/unit to ₹3.5/unit, wiping out roughly ₹36 Cr in annual earnings. The CFO departed in January 2026. And the working capital cycle has stretched to 534 days — yes, you read that right, 534 days — because building custom alloy steel piping for BHEL and GE requires ordering materials before you even see the client’s invoice.

They Bend Steel. For Very Serious People. At Very Serious Prices.

Let’s be clear about what DEE actually does. When a power plant in Gujarat needs to connect a 600 MW steam turbine to its boiler system with a network of pipes that must handle temperatures of 600°C and pressures that would turn your coffee maker into shrapnel — they call DEE. When Dangote’s refinery in Nigeria needs custom piping modules, they call DEE. When Toshiba needs HRSG piping for a combined cycle gas turbine — DEE. The company makes bespoke, engineering-heavy, mission-critical pipe systems that you cannot just order off Amazon.

The core business is process piping fabrication — piping spools, modular skids, induction bends, industrial stacks, wind turbine towers, and pressure vessels. 83.7% of FY25 revenue came from the piping division. 27.5% of revenues are exports, going to Canada, USA, Switzerland, Germany, Japan, Nigeria, and others. The client list reads like a who’s who of global heavy industry: GE, Toshiba, L&T, Thermax, Mitsubishi, Nooter Eriksen, Doosan, Honeywell.

It also runs two biomass power plants in Punjab — an 8 MW plant in Abohar and a 6 MW plant in Muktsar — under 30-year PPAs with PSPCL. This sounded like stable, recurring income until Punjab’s electricity regulator had an opinion about tariffs. More on that disaster in Section 6.
