6. Product Introduction:

Pipe commonly used material for: Q235A, Q235C, Q235B, 16Mn, 20 #, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb like.

Welded steel pipe blank is used in steel or steel, because of its different welding process is divided into the furnace pipe, welding (electric resistance welded) pipes and automatic arc welded pipe. Because of the different forms of welding pipe is divided into two and spiral welded pipe.


7. Production Process

Longitudinal production process is simple, high production efficiency, low cost, rapid development. Spiral Welded Longitudinal generally higher than high, can narrow the billet production of large diameter pipe, you can also use the same width of the billet production of different pipe diameters. However, compared with the same length of straight seam pipe weld length of 30 to 100%, and lower production rate.

Diameter larger or thicker pipe, usually made of steel billets directly, but only a small thin-walled pipe welded steel welded directly through it. Then after a simple polished, brushed on it


8. Pipe Process

Raw material unwinding - flat - cut and weld ends - Looper - Forming - Welding - both inside and outside bead removal - pre correction - induction heat treatment - sizing and straightening - Eddy Current Testing - off - pressure check - pickling - Final inspection (strictly) - Packaging - shipping.

9. Feature
Longitudinal production process is simple, high production efficiency, low cost, rapid development. Spiral Welded Longitudinal generally higher than high, can narrow the billet production of large diameter pipe, you can also use the same width of the billet production of different pipe diameters. However, compared with the same length of straight seam pipe weld length of 30 to 100%, and lower production rate.

10. Applications

Our products are widely used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, is one of the products of China's 20 key development. For the transport of liquids: Water supply, drainage. For gas transportation: Gas, steam, liquefied petroleum gas. For structural purposes: As piling pipe, as the bridge; Docks, roads, pipes and other building structures.
