301L, 301, 410, 316L, 316, 304, 439, 409L, 304L Gas Seamless Steel Pipe

To ensure the tubes meet the required standards, they are subjected to several tests like the Product Analysis, Hardness, Mechanical, Flattening, Flaring,

 Hydrostatic, or NDT tests, based on the client’s test requirements. The tubes must also conform to the applicable provisions of the current edition of Specification A 450/A 450M.
The ASTM A179 Tubes come in different sizes and varying wall thicknesses, and U-bending tubes can also be offered. Additionally, the tubes are subject to various test requirements, including ASTM A179 Tubes (ASME SA179 Tubes) Chemical Compositions, Mechanical Properties, Wall Thickness Tolerance, Outside Diameter Tolerance, Cut Length Tolerance, and Hydrostatic Test Pressures, to ensure quality.

Widely used in petroleum, chemical, medical, food, light industry, Industrial pipes and mechanical structural parts such as mechanical meters. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts. And engineering structure.It is also often used as furniture and kitchen utensils.
