ASTM A733 Material classification and scope of applicationCarbon steel pipe fittings
- Welded carbon steel: This is a material widely used in general piping systems, in accordance with ASTM A53/A53M and ASTM A333/A333M standards. ASTM A333/A333M is mainly used for low-temperature applications (such as liquefied natural gas equipment)
- Seamless carbon steel: Mainly suitable for ASTM A53/A53M (general application), A106/A106M (high temperature application) and A333/A333M (low temperature application), because the seamless design allows it to work normally under high temperature and high pressure, and can cope with special scenes and various overload working environments.
Austenitic stainless steel pipe fittings
In accordance with ASTM A312/A312M standards, the fittings are specially designed for high temperature and corrosive environments and are widely used in chemical design, food processing and other industries.
