ERW Black Steel Pipe DN150 ASTM A53 GR.B For Water Supply Projects

ASTM A53 Gr.B carbon steel is commonly used in water supply pipelines due to its balanced strength and good weldability. The material 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 installation stress. Its chemical composition typically limits carbon to below 0.30 percent and manganese up to about 1.20 percent, contributing to stable mechanical performance and ease of fabrication.

Huayang Steel Pipe manufactures DN150 ERW pipes using advanced high-frequency electric resistance welding technology, ensuring a continuous and uniform weld seam with stable metallurgical bonding. Precision forming guarantees accurate outer diameter and consistent wall thickness along the pipe body. Each pipe undergoes hydrostatic pressure testing, weld seam ultrasonic inspection, and dimensional verification. The black surface coating provides basic protection during storage and transportation, and can be supplemented with internal lining or external anti-corrosion coatings for extended service life in water supply environments.
