ASTM A671 / 672 / 691 Welded Pipe
Made from carbon steel, ASTM A671, A672 and A691 welded pipes are designed for low and normal temperature service. They are made by welding the edges of a workpiece made of sheet metal.
Welding of the workpiece is done with a double weld, assuming full penetration. At the same time, the qualification of the welder provides for compliance with ASME requirements and the availability of access to welding of pressure vessels.
You can buy ASTM welded pipes with an outer diameter of 406 to 1118 millimeters, with a wall thickness of 8 to 25.4 millimeters.
Heat treatment can be used to achieve special properties determined by the operating conditions.
Products are distinguished by high impact resistance and resistance to corrosion manifestations.
For welded pipes, the cost depends on their size and compliance with the special requirements of operation.
Welded products are used to form pipelines and pressure vessels, as well as structural elements in construction and engineering.
