Quality Control System
We have a strict Quality Control System, from raw material incoming inspection, production process control, finished product inspection, we have strict procedures to control quality and cost:
1. Inspection of incoming raw materials: chemical analysis, metallographic analysis
2. For welding products we will take welding evaluation report before welding
3. After welding, after post-weld heat treatment in strict accordance with the process, the finished product is 100% Nondestructive Tested: X-ray non-destructive testing, ultrasonic testing, penetration testing, etc.
4. Other strength test, Mechanical performance experiments.
Thus to ensure the strength and pressure of our products can meet the requirements of seamless pipe.
All products that pass the inspection can arrange packaging, shipping, etc.
Standard
