S235JR Electric Straight Seam Welded Pipe

S235JR Straight Seam Welded Pipe HFW/ERW Introduction

S235JR electric straight seam welded pipe is a longitudinally welded steel pipe made from S235JR structural steel using high-frequency resistance welding technology. This product has a minimum yield strength of 235MPa, and the weld, after heat treatment, exhibits properties consistent with the base material, possessing both good mechanical properties and process ductility. It boasts high dimensional accuracy and stable weld quality, and is widely used in building steel structures, low-pressure fluid transportation pipelines, and machinery manufacturing.

Quality Inspection of S355JR Electric Straight Seam Welded Pipe and ERW Pipe

In the quality inspection and testing process, we strictly adhere to international standards and implement comprehensive quality monitoring for S235JR electric straight seam welded pipes: We use ultrasonic flaw detection to perform non-destructive testing on the weld seam to ensure the integrity of the weld; we verify the pipe's pressure-bearing capacity and sealing performance through hydrostatic testing; we test key indicators such as the steel pipe's yield strength, tensile strength, and elongation through mechanical property testing; and we also conduct dimensional accuracy, surface quality, and chemical composition analysis to ensure that each batch of products meets specifications from internal performance to external dimensions, providing customers with reliable quality assurance.
