ASTM A53 GR.B ERW Steel Pipe DN300 For Low Pressure Fluid

ASTM A53 Gr.B carbon steel is commonly selected for low-pressure pipelines due to its balanced strength and good weldability. The material typically provides a minimum yield strength of approximately 240 MPa and tensile strength ranging from about 415 to 550 MPa, ensuring sufficient resistance to internal pressure and external mechanical loads. Its chemical composition is controlled with carbon generally below 0.30 percent and manganese content up to about 1.20 percent, contributing to stable mechanical properties and ease of fabrication.

Huayang Steel Pipe manufactures DN300 ERW pipes using advanced high-frequency electric resistance welding technology, producing a continuous and uniform longitudinal weld seam with consistent metallurgical properties. Precision forming ensures accurate outer diameter and uniform wall thickness along the pipe body. Each pipe undergoes hydrostatic pressure testing, weld seam ultrasonic inspection, and dimensional verification to meet quality standards. For low-pressure fluid applications, additional treatments such as galvanizing or internal coatings can be applied to enhance corrosion resistance and extend service life.
