Trushape casts valve bodies, pump impellers, wellhead and flow-control parts in duplex, super duplex, 316L, Inconel 625 and 50+ other alloys, then heat-treats, machines and tests them under one roof for equipment makers across North America and Europe.
Trushape Precision Castings is an ISO 9001, ISO 14001, ISO 45001 and ISO 13485 certified foundry in Bhavnagar, Gujarat, India that makes corrosion-resistant, pressure-tight castings for the oil and gas industry. We cast valve, pump, wellhead and flow-control components from 0.003 to 90 kg (0.007 to 198 lb) in carbon, stainless, duplex, super duplex, nickel and cobalt alloys, then heat-treat, CNC machine and inspect them in-house, with radiography to RT Level 1 on critical parts.
Our export desk serves valve, pump and equipment makers across the United States, Canada, Mexico, the United Kingdom, Norway and the European Union, as a single-source supplier and a proven China-plus-one alternative. Every batch ships with a material test certificate and records traceable to the heat, so your incoming inspection and your customers' audits both have what they need.
Thin vanes, one pour, no welds. Turn this investment-cast vaned ring through a full revolution, the way our inspectors see it before it ships to a compressor, turbine or pump builder.
Investment casting forms every vane, shroud and hub in a single pour, so there are no welded joints to crack under cyclic load.
Thin, uniform walls come out of the ceramic shell close to final size, which cuts machining and keeps the vane geometry true.
Bores, faces and seal lands are finished on 4-axis Makino VMCs to drawing tolerance.
CMM reports, dye penetrant and radiography confirm geometry and soundness, with results traceable to the heat.
Follow the line from the sea to the refinery. Upstream, midstream and downstream each attack metal in a different way, so each gets the alloy and casting process that suits its duty.
Seawater, chlorides and splash-zone attack decide alloy choice offshore. Super duplex, nickel alloys and seawater bronzes hold up where carbon steel would corrode fast.
Pressure, sour gas and sand. Wellhead and artificial lift parts need hardness control for H2S and trim that survives erosion.
Long runs of pressure cycling, wet gas and hard winters. Pipeline valves and compressor parts need sound walls and grades that stay tough in the cold.
Heat, acids and abrasive process streams. Refinery pumps and valves call for 316L, duplex, Inconel 625 and heat-resistant grades.
A floating ball valve looks simple until you specify it. Body, end connectors, ball and gland each see different stress and media, so each gets its own alloy and casting route. Scroll or use Explode view to take it apart, and drag to turn it. Green markers show the parts we cast and machine.
The pressure boundary. Cast in CF8M, CF3M, duplex 2205, super duplex 2507 or WCB by investment or shell casting, and radiographed where your plan requires.
Flanged or threaded ends that bolt to the body. Faces, seal pockets and bolt holes are machined in-house to drawing.
The quarter-turn closure. Cast in 316 or 17-4PH, then machined and polished to a true spherical finish that seals against the seats.
The stem seal and actuator interface, cast integral with the body or as a separate part and machined to a mounting pattern such as ISO 5211.
Shown for context. Seat pockets in the body and end connectors are machined to hold them precisely.

See all 50+ alloy gradesA valve body gets no second chance. It holds line pressure, shrugs off chlorides and H2S and stays tight for decades. So we cast, treat and test every pressure part as if the whole line depends on it, because it does.
Move the lens across the valve body. Radiography reveals what the eye cannot: shrinkage, gas porosity and inclusions inside the pressure wall. Critical parts can be cleared to RT Level 1 before machining and are checked again at final inspection.
A sound casting shows even density through the wall. This is the standard every critical part must meet before it moves on to machining.
Internal soundness of pressure walls, cleared to acceptance levels such as RT Level 1.
Wall thickness and internal flaws in heavy sections and flanges.
Surface-breaking cracks and porosity on stainless, duplex and nickel alloys.
Surface and near-surface flaws on carbon and low-alloy steels.
Every heat checked on Spectromaxx and Bruker spectrometers against your grade.
Mechanical properties to your material specification, and hardness for sour service limits.
Dimensional reports on bores, faces, seal pockets and profiles.
Leak and pressure checks on pressure-containing parts where your plan requires them.
One record from melt to dispatch, ready for your incoming inspection and your customers' audits. Material certificates are issued to EN 10204 3.1 as standard, and to 3.2 when your order calls for independent inspection.

We cast valve bodies, bonnets, end connectors, balls, discs and trim; pump impellers, casings, diffusers and ESP stages; wellhead and christmas tree parts; and manifold, fitting and instrumentation bodies. Parts run from 0.003 to 90 kg (0.007 to 198 lb) across six casting processes, supplied as-cast or machined ready to assemble.
For sour service we cast duplex 2205 (CD3MN), super duplex 2507 (CE3MN), 316L (CF3M), CA6NM, 17-4PH and Inconel 625, and control hardness with in-house heat treatment and testing. Typical NACE MR0175 / ISO 15156 limits include 22 HRC maximum for carbon and low-alloy steels and 33 HRC maximum for 17-4PH in the double H1150 condition.
Compare pitting resistance (PREN). 316L at about 25 suits mild chloride service. Duplex 2205 at about 35 adds roughly double the yield strength and better chloride stress corrosion resistance. Super duplex 2507 at about 42 is the usual choice for seawater and subsea duty, where a PREN of 40 or more is the common rule of thumb.
Yes. Trushape is an export-focused foundry with a dedicated export desk, serving valve, pump and equipment makers across North America and Europe, including the United States, Canada, Mexico, the United Kingdom, Norway and the European Union. Parts ship by sea or air freight with English documentation, and delivery terms are agreed per order.
Every batch ships with an EN 10204 3.1 material test certificate for chemistry and mechanical properties, or 3.2 when your order requires independent inspection. To match your inspection plan we add radiography to levels such as RT Level 1, ultrasonic, dye penetrant or magnetic particle testing, hardness and impact tests, pressure testing, CMM dimensional reports and heat treatment records, all traceable to the heat.
No. Trushape is certified to ISO 9001, ISO 14001, ISO 45001 and ISO 13485. We cast to your drawing, material specification and inspection plan, while product approvals such as API monograms, PED conformity and ASME stamps stay with the valve or pump manufacturer. We support your qualification with sample castings, test data and full records.
From 0.003 to 90 kg (0.007 to 198 lb). Investment casting covers 0.003 to 30 kg for thin-walled, detailed parts such as impellers and trim, while shell molding (5 to 60 kg), no-bake sand (3 to 40 kg) and lost foam (3.5 to 90 kg) handle larger valve bodies, casings and housings.
With 3D-printed patterns, first metal samples are typically ready in 2 to 4 weeks from a CAD file, with no wait for tooling. Series production on hard wax tooling usually needs 8 to 12 weeks to first delivery, depending on complexity, alloy and the testing you specify.
Yes. Our machine shop runs 8 CNC machines, including 4-axis Makino VMCs, so valve bodies, impellers and housings leave finished to drawing, with bores, seats, faces and threads machined and verified on a Zeiss CMM. One supplier handles casting, heat treatment, machining and testing.
Common pairs include CF8M and 1.4408, CF3M and 1.4409, duplex CD3MN and 1.4470, super duplex CE3MN and 1.4469, CA6NM and 1.4317, and WCB and 1.0619. We cast to the ASTM, EN or customer specification on your drawing and confirm the chemistry of every heat by spectrometer.
Investment casting gives the best surface finish, thin walls and tight tolerances, ideal for small and mid-size valve bodies, balls and trim up to 30 kg. Shell molding and no-bake sand casting suit larger, heavier bodies at lower tooling cost. We run both, so the process follows your size, volume and tolerance.
India offers a deep foundry base, strong engineering talent and competitive cost, and gives North American and European buyers a proven second source outside China. Trushape adds an integrated plant, four ISO certifications, more than 24 years of casting experience and English documentation to make that switch low risk.
When a casting has to hold line pressure and resist corrosion for decades, choose a foundry that treats integrity as non-negotiable. Trushape casts, heat-treats, machines and verifies oil and gas components for equipment makers across North America and Europe.
