GOST Butt Weld Pipe Fittings
Standard Guidelines:
GOST 17375-2001: Covers carbon/alloy steel buttweld fittings.
GOST 30753-2001: Applies to stainless steel buttweld fittings.
GOST 12220-84: Specifies welded fittings designed for the oil and gas industries.
Types of Pipe Fittings:
Elbows (45°/90°/180°), equal/reducing tees, concentric/eccentric reducers, and caps.
Production Description
GOST Butt Weld Pipe Fittings are pipe fittings that are manufactured according to the GOST standards and are used to connect, redirect, and control the flow of fluids and gases within a piping system. These fittings are primarily designed for welding onto the pipe using a butt-welding process, ensuring a strong and leak-proof joint.
Key GOST Standards We Manufacture
We produce the full suite of “Seamless Steel Butt-Welding Fittings” according to the following critical GOST specifications:
GOST 17375-2001: Carbon and Low-alloy Steel Elbows (Standard radius).
GOST 30753-2001: Carbon and Low-alloy Steel Elbows (Short radius for tight spaces).
GOST 17376-2001: Steel Tees (Equal and Reducing).
GOST 17378-2001: Steel Reducers (Concentric and Eccentric).
GOST 17379-2001: Steel Ellipsoidal Caps.
GOST 12820/12821: Steel Flanges (Plate and Weld Neck) for use with GOST fittings.

FAQ
Q: What is the difference between GOST 17375 and GOST 30753?
A: The main difference is the bend radius. GOST 17375 is Type 3D (R≈1.5D), which is the standard long radius. GOST 30753 is Type 2D (R≈1.0D), which is a short radius elbow used in confined spaces or specific vessel designs.
Q: Can you provide GOST fittings with “HL” (ХЛ) certification?
A: Yes, our 09G2S fittings are specifically processed to meet the HL (cold-resistant) category, suitable for deployment in Northern climatic zones.
