11. Inspection:  chemical and mechanical test on raw material (steel coil) and finished pipes, first production test, 100% UT, 100% hydraulic test, 100% dimension and visual test.

12.Usege:used for conveyance gas ,water ,petroleum  and conveyance of other fluid

13.Feature:

a. Low Cost: Low raw material cost and manufacturing cost makes its prices more competitive than longitudinal seam submerged-arc welded pipes and seamless pipes.

b. High Weld Seam Security: As a result of special welding method of melting the parent metal together,without filler metal,the weld property is better than submetged-arc welded pipes;and the weld seam is much shorter than spiral seam welded pipes,the seam security is greatly improved.
