Cold drawn / soft | +LC (BKW) | After the last heat treatment, follows the cold drawing there is a light finishing pass. |
Cold drawn and stress relieved annealed | +SR (BKS) | After the final cold drawing process, the tubes are stress-relieved and annealed in a controlled atmosphere. |
Annealed | +A (GBK) | After the last cold drawing process, the tubes are annealed in a controlled atmosphere. |
Normalized | +N (NBK) | After the last cold drawing process, the tubes are normalized in a controlled atmosphere. |
Quality Control
Strict Testing Chemical composition analysis: Ensure that the material composition meets the standard requirements. Mechanical performance testing: Including tensile testing, impact testing, etc., to ensure that the steel tube has sufficient strength and toughness. Non destructive testing: Using ultrasonic, eddy current, or radiographic testing techniques to detect internal defects in steel tubes. Hydraulic test: Each steel tube undergoes a hydraulic test to ensure good sealing and pressure bearing capacity in high-pressure environments. | Testing Standards Compliant with international standards such as GB3087, DIN17175, ASTM A53, ASTM A519, ASTM A106, ASTM A179, ASTM A192, etc. Each batch of products comes with detailed quality inspection reports and certificates of conformity. | Certification Guarantee Obtained ISO/TS16949:2009 quality system certification and obtained the national special equipment pressure pipeline component manufacturing license. |
