TDC Alloys is an ISO 9001:2015 and IBR certified, premier Valve & Pump Casting Manufacturer in Gujarat, delivering high-integrity cast steel solutions for fluid control, power generation, chemical processing, and pipeline transmission industries. Industrial valves and pumps represent the critical pressure-containing core of modern process plants, demanding absolute metallurgical soundness, zero porosity, and high tensile strength to handle severe hydraulic stresses, thermal cycling, and corrosive media. Our Valve & Pump Casting in Gujarat combines advanced 3D solidification modeling, medium-frequency induction melting, and automated no-bake resin sand molding to achieve defect-free castings complying with ASME, API, ASTM, and ISO standards.
Our foundry specializes in casting diverse fluid handling components from 5 kg up to 3,000 kg per piece. Our product portfolio includes wedge gate, globe, check, ball, and butterfly valve bodies, bonnets, discs, and plugs, alongside centrifugal pump volutes, split casings, closed and semi-open impellers, diffusers, and stuffing boxes. Available in cast carbon steel (WCB, WCC), alloy steel (WC6, WC9, C5, C12), low-temperature steel (LCB, LCC), stainless steel (CF8, CF8M, CF3, CF3M), duplex stainless steel (CD3MN, CE3MN), and Ni-Hard wear alloys, all castings undergo 100% NDT inspection and hydrostatic pressure testing up to 10,000 PSI across Gujarat.

As an experienced Valve & Pump Casting Manufacturer in Gujarat, TDC Alloys casts a wide range of certified pressure alloys:
The standard metallurgical choice for oil, gas, steam, and water transmission pipelines operating up to 425°C, providing exceptional weldability, impact resistance, and pressure tightness.
Chromium-Molybdenum cast alloy steels engineered for superheated steam headers, thermal power boiler feed pumps, and refinery cracking units operating up to 650°C.
Chromium-Nickel-Molybdenum alloys providing superior resistance to chemical attack, intergranular corrosion, and pitting in chemical process pumps and isolation valves.
Balanced austenitic-ferritic microstructure delivering double the yield strength of standard stainless steels and exceptional resistance to chloride stress cracking in seawater desalination.
Our programmable heat treatment regimens tailor the mechanical properties of each alloy heat to match exact operational service demands:
