Quality Assurance
Chemical Composition Control
- Spectrometer testing of all raw material lots before storage
- 100% PMI verification of mother pipes
- 100% PMI verification of finished pipes
Heat Treatment Process
Utilizing a 24-meter full-automatic natural gas furnace with temperature tolerance maintained within ±10°C for consistent material properties.
Comprehensive Quality Control
- Incoming raw material inspection
- Material segregation to prevent grade mix-ups
- Heating and hammering end preparation for cold drawing
- Cold drawing and cold rolling with online inspection
- Precision heat treatment (+A, +SRA, +LC, +N, Q+T)
- Straightening, cutting, and final dimensional inspection
- Complete mechanical testing including tensile strength, yield strength, elongation, hardness, impact, and microstructure analysis
Product Marking Requirements
- Marking includes condition: hot finished or cold finished
- For austenitic stainless steels with grain size requirements: includes heat number and heat-treatment lot identification
- For T2/T12 grades with higher sulfur content: includes letter "S" following grade designation
