DIN 17175 is a standard specification for seamless tubes of heat-resistant steels used in elevated temperatures and high-pressure environments.

This standard applies to seamless steel tubes for general structural and mechanical structures. The main production of steel pipe grade includes Gr 10, Gr 20, Gr 35, Gr 45, Q345, 15CrMo, and 12Cr1MoV.

ASTM A333 is the standard specification for seamless and welded carbon and alloy steel pipe for low temperature applications or other applications requiring notch toughness. This standard covers several grades of ferritic steel: Grade 3, Grade 4, Grade 6, Grade 7, Grade 8, Grade 9, Grade 10 and Grade 11.

ASTM A252 is the standard specification for nominal-wall cylindrical steel pipe piles, where the cylinder acts as a permanent load-bearing member or shell to form a cast-in-place concrete pile. The ASTM A252 specification has three grades: Grade 1, Grade 2, and Grade 3, of which Grade 2 and Grade 3 are commonly used materials.

A213 is a ferrite and austenitic alloy seamless steel pipe for boilers, superheaters and heat exchangers. Its products should comply with TSG D7002 pressure piping component type test rules.

ASTM A192 is the same as ASME SA-192 and is the standard specification covering seamless carbon steel boiler and superheater tubes of minimum wall thickness for high pressure service.

A179 seamless cold drawn low carbon steel pipe is equivalent to China's No. 10 high-quality low-carbon steel. A179 is suitable for cold-drawn high-quality low-carbon seamless steel pipes for heat exchangers and condensers.

Grade S355 is a low carbon manganese-containing steel alloy. This medium-strength carbon steel has both good weldability and good impact resistance. Grade S355 steel is also well suited for sub-zero temperature applications.

ASTM A335 steel pipe may be hot finished or cold drawn and subjected to the following finishing heat treatment. The specification covers chrome-molybdenum seamless pipes with excellent corrosion resistance and high temperature tensile strength.
