- 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 17376 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 17378 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.
