Several standards dictate the manufacturing of steel pipes to ensure consistency, quality, and safety. Among the most prominent are:
ASTM A53
This specification covers a range of black and hot-dipped galvanized welded and seamless steel pipes. It is widely used to convey gas, water, and oil in the natural and oil industries.
ASTM A106
Specifically designed for high-temperature services, ASTM A106 addresses seamless carbon steel pipe for high-temperature applications. It finds its usage in pressure vessels and processing plants.
ASTM A333
ASTM A333 focuses on seamless and welded steel pipes that operate at low temperatures. This specification is critical for applications where resistance to brittle fracture is essential, such as cryogenic installations.
ASTM A335
ASTM A335 covers seamless ferritic alloy steel pipes for high-temperature services and corrosion resistance. These pipes are used in power plants and other industrial settings.
Standard Specifications for Pipe Fittings
Like steel pipes, pipe fittings also adhere to standards to guarantee their quality and compatibility. Notable specifications include:
ASTM A234
Covering both wrought carbon and alloy steel fittings, ASTM A234 ensures suitable material composition, mechanical properties, and testing requirements.
ASTM A403
ASTM A403 focuses on standardizing wrought austenitic stainless steel pipe fittings for pressure piping applications.
ASTM A815
This specification addresses high-strength, corrosion-resistant duplex (austenitic-ferritic) stainless steel fittings for various industries, including chemical and petrochemical. Yaang can produce pipe fittings of such metal materials:
