A135 Resistance Welded Steel Pipe

A135 electric resistance welded steel pipe is a steel pipe produced according to the A135 standard established by the American Society for Testing and Materials (ASTM), and is mainly used to transport gas, steam, water or other liquids. This steel pipe is manufactured through the electric resistance welding process and has unique performance characteristics and a wide range of applications.
A135 electric resistance welded steel pipe sizes range from NPS 2 to NPS 30 (DN 50 to DN 750), with a nominal (average) wall thickness of up to 0.500 inches (12.70 mm). For smaller sizes of steel pipes (NPS 1/4 to NPS 5, DN 20 to DN 125), the nominal (average) wall thickness ranges from 0.083 inches (2.11 mm) to 0.134 inches (3.40 mm).
The A135 standard specifies two grades of electric resistance welded steel pipe, but only Grade A is suitable for flanging and bending. This means that in specific application scenarios, when the steel pipe needs to have a specific shape change capability, Grade A steel pipe should be selected.
Depending on the manufacturer's choice, A135 electric resistance welded steel pipe can be provided in non-expanded or cold-expanded versions. When cold-expanded steel pipe is selected, its expansion shall not exceed 1.5% of the outer diameter of the pipe size to ensure that the steel pipe maintains its structural integrity and performance stability during the expansion process.
The suitability of A135 electric resistance welded steel pipe depends on its size, performance and service conditions. Therefore, when ordering, the intended use of the steel pipe should be clearly stated to ensure that the selected steel pipe can meet the specific application requirements. This steel pipe is widely used in various industrial fields, such as petroleum, chemical, power, etc., as well as construction and civil fields.
In addition to meeting the requirements of ASTM A135 standards, A135 electric resistance welded steel pipe can also be customized according to user requirements. This includes customization according to specific size, wall thickness, material and performance requirements to meet the needs of specific application scenarios.
