SA691 5CR Alloy Steel EFW pipe Description

SA691 5CR welded pipe is A691 5CR welded pipe, which is used in high temperature and high pressure environment.
SA691 is ASTM A691, which is a standard formulated by the American Society for Testing and Materials (ASTM), which stipulates the technical requirements and test methods of carbon steel and alloy steel electric fusion welded steel pipes under high temperature and high pressure conditions.
5CR refers to 5% chromium alloy steel. This material has high strength, good high temperature resistance and certain corrosion resistance. It can maintain good stability and reliability under high temperature and high pressure environment. It is suitable for some industrial fields with high material performance requirements, such as high temperature pipeline systems in petrochemical, power and other industries.
