 advantages
1.Our company has been dedicated to producing stainless steel seamless pipe since 1995, owning complete producing technology and abundant managing experience.
2.The raw material such as mother tube, round bar we use is from chinese biggest and well-known steel mill.
3.Our company owns a full set of inspection/testing equipents including germany-imported direct-reading spectrometer, ultrasonic fault detector, eddy current flaw detector, hydrostatic testing machine, x-ray scenograph, nitrogen/oxyen analyzer, universal testi ng machine, impact tester, automatic carbon/sulfur analyzer, endoscope ect.We have iso 9001 and ped certificate, and the third party inspection certificates such as tuv, bv, lloyds, sgs, etc, also can be provided according to customers requirements,
4.Wooden case package which is strong and suitable for sea transportation is our main method to pack the pipes. And the economical packing method such as packed in bundles is also welcomed by some customers.
5.The tolerance control we use is d4/t4 (+/-0.1mm) on both inside and outside diameter and wall thickness, which is much higher than international standard astm, din.
6.The surface condition is one of our main advantages: in order to meet different requirements for surface condition, we have annealing and pickling surface, bright annealing surface, od polished surface, od & id polished surface etc.
