Specialty and advantages:
The raw material such as mother tube, round bar we use is from Chinese biggest and well-known steel mill.
We have advanced NDT equipment for the tests such as Eddy Current test, Ultrasonic test, Hydraulic test and so on.
We have ISO 9001 and PED certificate, and the Third Party Inspection Certificates such as TUV, BV, SGS, etc, also can be provided according to customers’ requirements,
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.
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.
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.
In order to keep the inside surface of pipe clean and make it free from deburring, our company develops the unique and special technology --- Sponge Washing with high pressure.
We have complete after-sale service to deal with the problems in time.
