ERW Welded Black Schedule 40 Carbon Steel Pipe

ERW Welded Black Schedule 40 Carbon Steel Pipe

​ERW steel pipes are made of hot rolled coils. It adopts cold-bending forming, and the sizing is completed by 0.6% reduction. The process temperature is basically constant at room temperature, so the outer diameter control is accurate and the fluctuation range is small, which is beneficial to prevent black leather buckle.

The tensile properties of ERW steel pipes are in line with API standards. Its strength index is in excellent condition, and the plasticity index is higher than the standard 33.3%. The reason is that the performance of the raw material is determined by means of microalloying smelting, refining outside the furnace and controlled cooling and rolling.
