Product Description

 

 Product Description

ASTM A250/A250M is a standard specification published by the American Society for Materials and Testing (ASTM). This standard specifies the material and performance requirements for resistance welding carbon steel and alloy steel pipes.
ASTM A250/A250M is primarily suitable for resistance welded carbon steel and alloy steel tubes for use in high temperature and high pressure operating environments. The standard covers a wide range of types and sizes of resistance welded carbon steel and alloy steel pipes, including seamless and welded pipes.
The standard has detailed requirements and test methods for the chemical composition, mechanical properties, tensile properties, bending properties, hardness and impact toughness of the pipe. In addition, the standard also specifies the size of the pipe, appearance quality, allowable defects and other requirements.
The ASTM A250/A250M standard is designed to ensure the high quality, reliability and durability of resistance welded carbon and alloy steel pipe materials to meet the needs of a variety of industrial applications, such as oil and gas transmission, chemical, and power.
