Our products are manufactured in strict accordance with the international recognized and accredited product standards, including API, ASME, ASTM and TEMA.   We are making every effort to ensure all of our manufacturing facilities follow the strict guidelines established under quality-control organization standards ISO 9001, 9002 and ISO 14000.  We have been working very closely with BV, Lloyds, PED, TUV and other world-standard certificate-awarding organizations.
As a part of the comprehensive quality control due diligence, we maintain a quality management system, which monitors the complete manufacturer process, starting from the selection of raw material through to final inspection and packaging.  Before completion, all of our products undergo rigid tests, including the testing of chemical and mechanical properties, metallographic, hardness, impact, ultrasonic, hydrostatic, liquid penetrant and radiography.
From time to time, we also require our experienced inspectors and engineers undergo various types of continuing education and training.  In this way, they can improve their technical levels in order to better perform such non-destructive inspection.
