S235JR Automatic Arc Welding Pipe

S235JR Automated Submerged Arc Welding Straight Seam Welded Pipe Product Introduction

The S235JR type automated electric arc welded pipe is a welded steel pipe formed using submerged arc welding technology. This product achieves stable weld formation through an automated welding system. After heat treatment, the mechanical properties of the weld are coordinated with the base material, possessing both good pressure resistance and structural strength. It is mainly suitable for low-pressure fluid transportation, building structural support, and general engineering fields, providing a cost-effective and practical solution for medium and large diameter pipes.

Non-destructive Testing of S235JR Submerged Arc Welded Straight Seam Pipe

For S235JR automatically welded arc pipes, we implement a rigorous non-destructive testing process: ultrasonic testing is used to scan the entire length of the weld seam to accurately detect internal defects such as incomplete fusion and porosity; radiographic testing is used to record and analyze images of the weld joints to ensure the internal quality of the weld seam; and magnetic particle testing is used to detect surface and near-surface cracks in the pipe body. This complete testing system can effectively identify various defects that may exist during the manufacturing process, ensuring the structural integrity and safety reliability of each welded pipe, and fully complying with international standards for the quality requirements of structural welded pipes.
