Standard Specifications for Steel Pipes
Various standards govern the production of steel pipes to ensure consistency, quality and safety. The most important include:
ASTM A53
This specification covers a variety of hot-dip galvanized and black seamless and welded steel pipes. It is widely used to transport gas, water and oil in the oil and petroleum industries.
ASTM A106
ASTM A106 is specifically designed for high temperature applications and includes seamless carbon steel pipes for high temperature applications. It is used in pressure vessels and processing plants.
ASTM A333
ASTM A333 focuses on seamless and welded steel pipes used at low temperatures. This specification is critical for applications where resistance to brittle fracture is critical, such as: B. in cryogenic systems.
ASTM A335
ASTM A335 includes seamless ferritic steel alloy pipes for high temperature applications and corrosion resistance. These tubes are used in power plants and other industrial environments.
Standard Specifications for Pipe Fittings
Like steel pipes, pipe fittings also meet standards to ensure their quality and compatibility. Key specifications include:
ASTM A234
ASTM A234 applies to forged carbon steel and alloy steel connections and ensures proper material composition, mechanical properties and testing requirements.
ASTM A403
ASTM A403 focuses on standardizing forged 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 from the following metal materials:
