Customer Visit to Production Line

During their visit, the Thai customer had the opportunity to tour our production line for 316 stainless steel seamless pipes. The customer was impressed with the level of precision and technology used throughout the manufacturing process, from billet selection and extrusion to final inspection. Our production team demonstrated the various stages involved in creating seamless pipes, highlighting the importance of maintaining high standards of quality and accuracy.

 ASTM A312 / ASME SA312

The customer observed how our team ensures the precise dimensions, surface quality, and material integrity of every pipe. They were also given insight into our advanced testing processes, including dimensional checks, pressure testing, and chemical composition analysis, to guarantee that every pipe meets international standards.

Inspection and Testing: Every batch of pipes undergoes rigorous testing, including:

Dimensional Accuracy: Ensuring that the pipes conform to precise size and thickness specifications.

Surface Quality Checks: Verifying that the pipes are free from surface defects such as scratches, dents, or oxidation.

Chemical Composition Analysis: Confirming that the pipes meet ASTM A312 standards for material composition.

Hydrostatic and Pressure Testing: Ensuring the pipes can withstand high-pressure environments without failure.

Non-Destructive Testing (NDT): Ensuring that no internal defects compromise the pipe's performance.
