Dredge Spiral Steel Pipe

Description of Dredge Spiral Steel Pipe

Dredge Spiral Steel Pipe is suitable for transporting silt,slurry and other mixed sundries.It can be worked with dredge floater and dredge rubber hose for one pipeline.Dredge spiral steel pipe can be used on land and offshore.Flanges are available as required.

First and foremost,the production technology of dredge spiral steel pipe is simple. Its production efficiency is high.Its cost is low. Its development is rapid.The strength of the dredge spiral welded pipe is generally higher than dredge straight seam welded steel pipe.The narrow billet can be used for producing larger diameter welded steel pipe.The same width of billet can also be used for producing different diameter welded steel pipes.But dredge spiral steel pipe is compared with the same length of dredge straight seam steel pipe,its welded length will increase by 30 ~ 100%and the production speed is low.As a result, large diameter dredge welded steel pipe mostly adopts spiral welded spiral steel pipe.

All the Hi-sea dredge spiral steel pipes passe the strict test,especially ISO9001:2000.

Certificates:API 5L ,API 5CT ,ISO ,CE, etc

Standard:ASTM A53,API 5L PSL1,PSL2, CE, API 5CT,KS,ISO,BV ,etc
