As a whole, our company is, and always has been, focused on ingenuity as a basis of our operations. We are
consistently committed to discovering new solutions that function as solutions capable of solving even the
most complex issues
Quality Goal: Continuous improvement & Zero defect, Meeting and even exceeding the quality and service
needs of customers.We own interior quality assurance system, implementing over all quality management in
the whole process. Every and each valve has a unique heat number to achieve traceability. All raw materials
must carry on the material composition and mechanical performance review before entering the factory, to
completely eradicate unqualified materials. Nondestructive testing for valvepipes is necessary before and during
raw material processing. Valves should pass valve body strength test, hydraulic pressure seal test and gas seal test
one by one before leaving factory. Besides, valves for specific application need more tests, such as RT, DPI, MT, UT,
spectral analysis, PMI, low leakage test, high & low temperature cycle test, life test, fire test, extra-cryogenic test,
microstructure test, all type mechanical properties test, deoiling skim cleanness test and so on, to guarantee all
products are all qualified before delivery.
Except internal severe work system and workflow, there are also the third party certification authority and customer
approval to ensure quality. company has been passed ISO9001，CE-PED，API6D，API607 certified. We are still working
on the improvement of quality control and management capacity.
