A178 C seamless steel pipe has excellent mechanical properties, with a tensile strength of up to 410MPa and a yield strength of 245MPa. Therefore, it performs well in situations with high strength and pressure, and can meet the application requirements of various complex working conditions.
A178 C seamless steel pipe has a high surface hardness and can reach a hardness of 60-85 HRA after heat treatment. Therefore, in situations where friction and wear are large, it can effectively resist wear and deformation, and has good wear resistance.
A178 C seamless steel pipe has good corrosion resistance because it is made of high-quality steel. In harsh environments such as strong acid, strong alkali, high temperature, and high pressure, it is not prone to corrosion and oxidation and has a long service life.
ASTM A192 is the standard for minimum wall thickness seamless carbon steel boiler and superheater tubes for high pressure applications. This kind of steel pipe is usually used in high-pressure boilers whose working pressure does not exceed 9.8Mpa.
ASTM A192/ASME SA-192 carbon steel seamless pipes are widely used in various industrial fields, including sugar cane industry, fossil thermal power plants, chemical and petrochemical industries, etc. These steel tubes play a vital role in the construction of boilers and superheaters, providing critical support for the reliability and durability of these equipment. They are also often called "boiler tubes" or "superheater tubes".
