GOST 17376-2001 PDF

Full title and description

GOST 17376-2001 — "Carbon and low-alloy steel butt-welding fittings. Tees. Design." The standard specifies design and general dimensional requirements for seamless and welded T-shaped pipe fittings (equal and reducing tees) manufactured from carbon and low-alloy steels for industrial piping systems.

Abstract

GOST 17376-2001 defines the constructional (design) parameters for steel butt-weld tees used in pipelines and pressure systems, including execution types, basic dimensions, material families (carbon and low-alloy steels), marking and designation conventions, and typical operating ranges. The standard is applied to tees for oil, gas, chemical and power industry piping and covers both equal and reducing tees in common industrial diameters and wall thicknesses.

Scope

The standard applies to the design of butt-welding tees (T-fittings) made of carbon and low-alloy steels intended for use in industrial piping systems (including oil, gas, chemical and energy sectors). It covers equal and reducing tees, execution variants, nominal diameter and wall-thickness ranges commonly produced to GOST practice, and the designation/marking rules used to identify tees manufactured per this standard. It does not replace detailed material specifications, welding procedure qualifications, or project-specific pressure/temperature ratings — those are taken from material standards and project requirements.

Key topics and requirements

• Design and geometry for equal and reducing butt-weld tees (basic dimensions, branch geometry and transitions).
• Execution types and dimensional series (commonly referenced as execution 1 and execution 2 variants).
• Applicable steel types: carbon and low-alloy steels commonly used for pressure piping (material grades referenced to national lists or companion material standards).
• Designation, marking and example symbols for tee items (format for indicating diameters, wall thickness and steel grade).
• Tolerances, permissible deviations and basic quality requirements related to manufacturing of seamless and welded tees.
• Reference to related GOST standards for complementary fittings (elbows, reducers, flanges) and inspection/testing practices where required by contract.

Typical use and users

Main users are pipe-fitting manufacturers, fabricators and suppliers who produce butt-weld tees to meet Russian/Eurasian market requirements; engineering, procurement and construction (EPC) contractors and pipeline designers who specify fittings for oil & gas, chemical, power generation and industrial piping; and procurement/quality teams that verify compliance of tees supplied to projects. Manufacturers selling to international projects that accept GOST fittings also use this standard to align product dimensions and marking.

Related standards

GOST 17376-2001 is commonly referenced alongside other GOST piping-fitting standards in the same family, for example GOST 17375 (elbows), GOST 17378 (reducers), GOST 17379 (crosses) and GOST 17380 (flanges) as well as material and testing standards that specify steel grades and inspection requirements. Vendor and standards catalogs list these as companion documents when ordering complete fitting sets.

FAQ

Q: What is this standard?

A: GOST 17376-2001 is a Russian national standard that sets out design requirements for carbon and low-alloy steel butt-welding tees (T-shaped pipe fittings).

Q: What does it cover?

A: It covers constructional (design) parameters and dimensional series for equal and reducing tees, marking/designation conventions and related tolerances; it serves as the design reference for manufacturing tees to GOST practice but defers to material and testing standards for steel grades and inspection regimes.

Q: Who typically uses it?

A: Manufacturers of butt-weld tees, pipeline and plant designers, EPC contractors, procurement and quality teams working on oil & gas, chemical, power and general industrial piping projects where GOST fittings are specified or accepted.

Q: Is it current or superseded?

A: Catalog listings and standards distributors show GOST 17376-2001 as an active/valid document in public catalogs (publication/registration date commonly shown as 01.01.2003); users should check the national registry or Rosstandart for the absolute current status and any amendments before relying on it for procurement or certification.

Q: Is it part of a series?

A: Yes — it is part of a family of GOST standards dealing with butt-weld pipe fittings (the 1737x series), which includes related documents for elbows, reducers, crosses and flanges used together in piping systems.

Q: What are the key keywords?

A: Butt-welding fittings, tee, equal tee, reducing tee, carbon steel, low-alloy steel, design, GOST 17376-2001.
