GOST Pipe Fittings Manufacturer

Russian Standard Steel Pipe Fittings for Industrial Pipeline Systems

GOST Pipe Fittings are steel pipeline components manufactured according to Russian and CIS technical standards for connecting, redirecting and controlling industrial piping systems.

We supply GOST steel pipe fittings including elbows, tees, reducers, caps, bends and customized fittings for oil & gas, petrochemical, power generation, chemical processing and industrial pipeline applications.

Our GOST pipe fittings are available in carbon steel, low-temperature steel, stainless steel and alloy steel materials according to customer drawings, technical specifications and project requirements.

With experience supplying international pipeline projects, we provide GOST fittings with material traceability, inspection documentation and export packaging.


What Are GOST Pipe Fittings?

GOST Pipe Fittings are pipeline connection components designed according to Russian standard requirements.

They are used to:

  • Change pipeline direction
  • Connect branch pipelines
  • Reduce pipe diameter
  • Close pipeline ends
  • Connect equipment and piping systems

Common GOST pipe fittings include:

  • GOST Elbow
  • GOST Tee
  • GOST Reducer
  • GOST Cap
  • GOST Bend
  • Custom GOST Fittings

Types of GOST Pipe Fittings

GOST 17375 ELBOW

GOST 17375 specifically defines sharply curved bends of Type 3D. The “3D” designation indicates that the bending radius of the elbow is roughly equal to 1.5 times the nominal diameter , which corresponds directly to a Long Radius (LR) elbow in Western engineering frameworks like ASME B16.9

GOST elbows are used to change the direction of pipeline systems.

Available types:

  • 45 Degree Elbow
  • 60 Degree Elbow
  • 90 Degree Elbow
  • 180 Degree Elbow

    GOST 17376 Tee

    GOST 17376 (current standard GOST 17376-2001) is the companion interstate standard that specifies the design, dimensional parameters, and structural requirements for carbon and low-alloy steel butt-welding piping tees.

    GOST tees are used for pipeline branching and flow distribution.

    Available types:

    • Equal Tee
    • Reducing Tee
    • Seamless Tee
    • Welded Tee

    GOST 17378 Reducer

    GOST 17378 Reducer is a Russian standard butt welding reducer fitting designed for connecting pipes with different outside diameters in pressure piping systems. Manufactured according to GOST 17378-2001, these reducers are widely used in oil & gas, petrochemical, power generation, and industrial piping applications across Russia and CIS countries.

    GOST reducers connect pipes with different diameters.

    Types:

    • Concentric Reducer
    • Eccentric Reducer

    GOST 17379 Cap

    GOST 17379 Cap (ГОСТ 17379 Заглушка эллиптическая) is a Russian standard butt welding elliptical pipe cap used for closing the ends of pipelines, pressure vessels, and piping systems. It is manufactured according to GOST 17379-2001, which specifies the design and dimensions of carbon steel and low-alloy steel elliptical caps

    GOST caps are used to close pipeline ends and equipment connections.
