Carbon Steel Pipe

The A53 American standard seamless steel pipe is manufactured from high-quality steel billets using processes such as hot rolling, cold drawing, and others. The chemical composition and mechanical properties of this steel pipe adhere to the specifications outlined in the American standard ASTM A53/A53M.

ASTM A106 grade seamless steel pipe is extensively utilized as a low carbon steel in the petroleum, chemical, and boiler industries. This material is known for its favorable mechanical properties and finds widespread application in various industrial settings.

The A179 seamless cold drawn low carbon steel pipe is comparable to China’s No. 10 high-quality low-carbon steel. A179 is well-suited for cold-drawn, high-quality, low-carbon seamless steel pipes used in heat exchangers and condensers.

ASTM A192, also known as ASME SA-192, is the standard specification that encompasses seamless carbon steel boiler and superheater tubes with minimum wall thickness for high-pressure service.

A213 is a seamless steel pipe made of ferritic and austenitic alloy, designed for use in boilers, superheaters, and heat exchangers. Its products are required to adhere to the TSG D7002 pressure piping component type test regulations.

ASTM A252 serves as the standard specification for nominal-wall cylindrical steel pipe piles, where the cylinder functions as a permanent load-bearing member or shell to create a cast-in-place concrete pile. The ASTM A252 specification encompasses three grades: Grade 1, Grade 2, and Grade 3, with Grade 2 and Grade 3 being commonly.

ASTM A333 is the standard specification for seamless and welded carbon and alloy steel pipes designed for low-temperature applications or other applications necessitating notch toughness. This standard encompasses various grades of ferritic steel, including Grade 3, Grade 4, Grade 6, Grade 7, Grade 8, Grade 9, Grade 10, and Grade 11.

The ASTM A335 steel pipe may undergo hot finishing or cold drawing and is then subjected to the following finishing heat treatment. This specification encompasses seamless pipes made of “chrome-molybdenum” with outstanding corrosion resistance and high-temperature tensile strength.

API Spec 5L is a global standard that outlines the manufacturing criteria for two product specification grades (PSL 1 and PSL 2) of seamless and welded steel pipes utilized in pipeline transportation systems within the oil and gas industry.

The carbon steel square tube is a steel pipe with a square cross-section, primarily consisting of elements such as carbon, manganese, silicon, phosphorus, sulfur, and others. These square pipes find extensive applications in areas such as building structures, mechanical manufacturing, highway construction, and more.

DIN 1629 seamless steel pipes consist of three primary grades: St37.0, St44.0, and St52.0. Typically, the DIN 1629 standard does not impose restrictions on the working pressure value, while the working temperature is limited to below 300°C.

This standard pertains to seamless steel tubes intended for general structural and mechanical applications. The primary steel pipe grades produced include Gr 10, Gr 20, Gr 35, Gr 45, Q345, 15CrMo, and 12Cr1MoV.
