Industrias a las que servimos
We support oil and gas equipment manufacturers, valve and pump builders, instrumentation producers, and service companies sourcing replacement spares. Our team manufactures flow control hardware, measurement system components, and surface equipment parts across upstream, midstream, and downstream applications. Each unit is produced to the customer drawing, in corrosion-resistant grades, with material certificates and inspection records supplied.
Manufacturing Capabilities for Oil and Gas
Yijin Solution combines CNC machining, CNC turning, sheet metal fabrication, custom fastener production, and surface finishing for oil and gas projects. Managing these processes through one supplier keeps drawing revisions, inspection records, and lot traceability under a single quality system. Our team supports prototyping through repeat production in corrosion-resistant grades, including stainless steel, duplex, alloy steel, and nickel alloys.

Mecanizado CNC
Mecanizado CNC covers milled valve bodies, manifold blocks, housings, and porting in 316 and 316L stainless steel, 17-4 PH, duplex grades, and alloy steel. Machined features reach plus or minus 0.01 mm when geometry and material allow. Standard machined work sits at plus or minus 0.05 mm.

Fabricación de chapas metÔlicas
Formed control panel enclosures, instrument housings, brackets, and guards run in stainless and coated steel sheet. Precision tolerance reaches plus or minus 0.10 mm and standard tolerance sits at plus or minus 0.30 mm, both under stated conditions.

CNC Turning and Swiss Turning
Turned work covers bodies, adapters, stems, nozzles, and crossovers. Swiss turning holds small diameter instrumentation parts at length across more than 80 Swiss-type lathes. The 80-plus Swiss-type lathe fleet carries that work. Turned diameters run to 400 mm.

Fijaciones a medida
Studs, nuts, and bolts are cold-headed in-house and secondary threaded to plus or minus 0.02 mm across 150 cold-heading machines. Oilfield programs consume threaded hardware alongside machined bodies, so both run under one quality system here.

Acabado de superficies
Passivation, black oxide, electroplating, and applied coatings protect stainless and alloy steel components in corrosive service. Salt spray testing sits within the 281 instrument inspection set, so corrosion protection is verified in-house rather than assumed.
Parts We Make for
Petróleo y gas
We manufacture custom oil and gas parts from customer drawings and 3D CAD files. Each part is produced to the specified material, tolerance, finish, and inspection requirements.
- Valve bodies and bonnets milled – in stainless and alloy steel with sealing face finishes
- Flanges, adapters, and crossovers – turned in steel with face and bore concentricity held
- Stems, seats, and gate components – in hardened stainless steel with ground sealing surfaces
- Pump housings and wear rings – in alloy steel and bronze bearing materials
- Manifold blocks with drilled and milled porting – in 316 stainless steel
- Threaded connectors and couplings turned and thread gauge verified
- Wellhead and surface hardware components machined as bodies and adapters to customer drawings
- Instrument and sensor housings machined in stainless steel with sealed cavities
- Studs, nuts, and custom fasteners cold-headed to plus or minus 0.02 mm
- Bushings, sleeves, and spacers in bronze and stainless bearing surfaces
- Control panel and junction enclosures formed in stainless sheet
- Test fixtures, jigs, and check gauges machined for assembly verification
From Idea to Production
Every oil and gas project starts with a free DFM review, where tolerances, datums, thread callouts, and grade substitutions are settled before the first cut. For early-stage programs, our new product development services extend that support into concept work and design ahead of tooling. Prototyping typically takes 3 to 7 days, and revisions are absorbed inside the same fixturing rather than restarting qualification. Production scales in the same facility under the same quality system, and inspection records travel with the parts at both stages.
Why Oil and Gas Manufacturers Choose Yijin

Precisión y calidad
Yijin Solution machines components to plus or minus 0.01 mm on suitable features under an ISO 9001-certified quality system, with Zeiss CMM dimensional reports available on request.

Material Breadth
Machining and fabrication run across 316 and 316L stainless steel, 17-4 PH, duplex grades, alloy steel, and nickel alloys, with grade selection confirmed against the drawing.

Prototyping to Production
Prototyping typically takes 3 to 7 days and moves into production inside the same facility, with no requalification at a second supplier.

Order Any Size
887 pieces of production equipment, including 136-plus CNC machining centers, support single replacement spares through repeat production runs.

Rentable
Direct factory pricing pairs with a free DFM review at the quote stage, which settles tolerance questions before cutting starts.

Oil And Gas Parts Manufacturer FAQs
Which certifications does Yijin hold for oil and gas work?
The certifications held are ISO 9001, ISO 14001, ISO 13485, and IATF 16949. API Q1 is not among them, and the quality system instead provides documented in-process inspection, final inspection records, and lot traceability on request. An API monogram is issued by the American Petroleum Institute against its own specification and covers a licensed facility rather than an individual machined part.
What tolerances are achievable on oil and gas components?
Machined features reach plus or minus 0.01 mm when geometry and material allow, and standard machined work sits at plus or minus 0.05 mm. Sheet metal parts reach plus or minus 0.10 mm at precision tolerance and plus or minus 0.30 mm at standard tolerance. Achievable tolerance depends on feature type, wall section, material condition, and the inspection method agreed upon at the quote stage.
Which corrosion-resistant grades are machined for oilfield components?
Common grades include 316 and 316L stainless steel, 17-4 PH, duplex grades, alloy steel, and nickel alloys. Grade choice affects both cost and lead time. Nickel alloys and duplex grades cut more slowly than austenitic stainless steel, which extends machining time. Buyers specifying sour service reference NACE MR0175 hardness limits, and grade selection with heat treatment conditions are confirmed against the customer drawing before quoting.
What is the maximum part size for machined oil and gas components?
Milled work runs within 3000 mm long, turned work within 400 mm diameter, and sheet metal within 2440 by 1220 mm. Larger valve and wellhead bodies fall outside that envelope and are better placed with a shop built around heavy turning. Confirming the envelope early saves a quoting cycle on parts that were never a fit.
Are material certificates and first article inspection reports available?
Both are available on request and are prepared alongside the parts rather than after shipment. Mill test reports carry chemical composition, mechanical properties, and the heat number for the supplied material. First article inspection reports carry measured features against the drawing, recorded on Zeiss CMM and supporting instruments.
What lead times apply to oilfield prototypes and production runs?
Prototyping typically takes 3 to 7 days, with production following in 2 to 4 weeks. Part complexity, grade availability, finishing scope, and inspection requirements all move those figures. Confirmed lead times are issued with the quote once the drawing package and grade are settled.

An oilfield component program is judged at the end on whether the parts and their records hold up when a customer reviews them.
Yijin Solution machines those components under an ISO 9001-certified quality system, with inspection records prepared alongside the parts.
