Product Introduction

Effective quality control and inspection during the manufacturing process of SS400 ERW Weld Steel Pipe are essential to ensure the pipe's performance. Here are some key steps and measures to consider:

Material Testing: Raw materials should be tested for quality and consistency to ensure they meet the required standards for strength and durability.

Dimensional Inspection: The dimensions of the pipe, including diameter and wall thickness, should be checked to ensure they meet the required specifications.

Welding Inspection: The welding process should be closely monitored to ensure proper fusion without defects. This can involve visual inspections as well as non-destructive testing (NDT) methods.

Non-Destructive Testing (NDT): NDT methods such as ultrasonic testing, radiographic testing, and magnetic particle inspection can be used to detect internal and surface defects in the weld and the pipe's body.

Hydrostatic Testing: This test involves pressurizing the pipe with a non-compressible fluid to ensure it can withstand the internal pressures it will be subjected to in service.

Flattening and Flaring Tests: These destructive tests are performed to check the weld's ductility and integrity by deforming the pipe and observing if the weld area shows any cracks.

Online Monitoring: Real-time monitoring of the welding process is crucial. This can include the use of advanced systems like the ONWELD system, which uses laser profile sensors or vision systems to scan and analyze the weld surface geometry, providing immediate feedback on weld quality.
