Changzhou Tenjan Steel Tube Co., Ltd. has earned the trust and choice of numerous customers through its unwavering commitment to quality consistency. We understand that every seamless steel tube carries the weight of our customers' product quality and corporate reputation, which is why we regard quality consistency as the lifeline of our enterprise.

End-to-End Quality Control: Precision Management from Raw Materials to Finished Products

Quality consistency begins with the selection of raw materials. We have established strategic partnerships with large steel groups such as Baosteel and Shagang to ensure the reliability and stability of raw material sources. Every batch of incoming raw materials undergoes rigorous testing, including chemical composition analysis using direct-reading spectrometers to ensure full compliance with requirements. This strict control from the source lays a solid foundation for the quality consistency of our seamless steel tubes.

During the production process, we implement standardized operating procedures to ensure that every step has clear operational guidelines and inspection standards. From tube piercing, rolling, heat treatment, to finishing, each process is equipped with strict control points. Through digital control systems, we monitor process parameters in real time, ensuring stability and consistency throughout production.

Advanced Equipment: Technical Assurance for Quality Consistency

We have invested significantly in advanced production equipment to provide hardware support for quality consistency. Cold rolling mills, heat treatment production lines, and various testing instruments ensure the precision and stability of our production processes.

Testing System: Multi-Layered Assurance for Quality Verification

We have established a comprehensive testing system equipped with advanced inspection devices such as ultrasonic flaw detectors and eddy current testing instruments. Every seamless steel tube undergoes over 20 testing procedures, including dimensional inspection, surface examination, non-destructive testing, and mechanical performance testing.

To ensure the accuracy of test results, we regularly calibrate and verify our testing equipment. All testing personnel are professionally trained and certified.

Certification System: Quality Management According to International Standards

We have obtained ISO 9001 Quality Management System certification and IATF 16949 Automotive Quality Management System certification, strictly implementing quality management in accordance with international standards.
