GOST 17374 is a Russian standard that specifies the requirements for steel butt-welding pipe fittings. The standard covers a range of fittings including elbows, tees, reducers, caps, and flanges, and is intended for use in pipelines conveying liquids and gases at various pressures and temperatures.
The standard specifies the dimensions, tolerances, materials, testing methods, and marking requirements for the fittings. It also includes provisions for the design and manufacture of fittings, as well as requirements for their installation and maintenance.
GOST 17374 is widely used in Russia and the former Soviet Union countries, and is recognized as a reliable and high-quality standard for steel butt-welding pipe fittings. The standard is also used by many international companies that do business in Russia or with Russian partners.
Overall, GOST 17374 plays an important role in ensuring the quality and safety of steel butt-welding pipe fittings used in pipelines, and helps to provide a basis for international trade and cooperation in this field.
GOST 17374 is a Russian standard for steel butt-welding pipe fittings, and it has some similarities and differences compared to other international standards. Here are some key points of comparison:
1. Dimensions and materials: GOST 17374 specifies the dimensions and materials for steel butt-welding pipe fittings in metric units, while other international standards such as ASTM and ASME use imperial units. However, the dimensions and materials specified in these standards generally overlap and can be converted between units.
2. Testing methods: GOST 17374 specifies various testing methods for steel butt-welding pipe fittings, such as hydrostatic testing, radiographic testing, and ultrasonic testing. Other international standards such as ASTM and ASME also specify testing methods, but the details may differ slightly.
3. Certification and marking: GOST 17374 requires that steel butt-welding pipe fittings be certified and marked according to certain criteria, such as the manufacturer’s name, the nominal size, and the standard number. Other international standards may have similar requirements, but the specific details may vary.
4. Regional application: GOST 17374 is primarily used in Russia and the former Soviet Union countries, while other international standards such as ASTM and ASME are used more widely in other parts of the world. However, many international companies that do business with Russia or with Russian partners may also use GOST 17374 or have to comply with its requirements.
Overall, while there may be some differences between GOST 17374 and other international standards for steel butt-welding pipe fittings, they share many common features and serve similar purposes in ensuring the quality and safety of these fittings.
