JIS G3445 ERW Carbon Steel Pipe

JIS G3445 electric resistance welded pipe is a carbon steel welded steel pipe that complies with the Japanese industrial standard JIS G3445. It is manufactured using the electric resistance welding process. The weld is parallel to the longitudinal direction of the steel pipe. It is mainly used for general structural purposes such as building support and fluid transportation. ‌

Its material is based on carbon steel. The heat generated by the current passing through the workpiece is used to form the weld during the welding process. It is highly efficient but the quality of the weld needs to be strictly controlled to prevent weak links. ‌

Advantages

• High production efficiency: It is made of steel plate or strip steel curled and welded. The production process is relatively simple and the production speed is fast. It can quickly meet market demand and improve production efficiency.
• Low cost: Compared with other types of steel pipes such as seamless steel pipes, the production cost of JIS G3445 welded pipes is lower, which makes it have certain advantages in price and can reduce the user's procurement cost.
• Various specifications: Steel pipes of various specifications can be produced according to different needs, including different outer diameters, wall thicknesses, etc., which can meet the requirements of different mechanical structure designs.
• Moderate strength: It has certain strength and rigidity, can withstand certain mechanical loads and pressures, and meet the use requirements of mechanical structures. At the same time, its strength is moderate, and it will not cause material waste due to excessive strength.
• Good welding performance: Carbon steel welded pipes have good welding performance, are easy to weld, and can be easily connected with other components to form complex mechanical structures.

‌Applications
Machinery and equipment parts: widely used in the manufacture of mechanical structural parts such as automobiles, bicycles, and furniture.
Architectural structure support: stability components such as railings and scaffolding serving the construction industry.
Fluid delivery system: used for pipelines for low-pressure media such as water, gas or air to ensure safe circulation.
