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
Certificates:API 5L ,API 5CT ,ISO ,CE, etc
Standard:ASTM A53,API 5L PSL1,PSL2, CE, API 5CT,KS,ISO,BV ,etc
Features of Dredge Spiral Steel Pipe :
Smooth wall improves transportation efficiency,it has long service
The mechanical strength is the same with steel pipe.
It has mature installation process,it is convenient.
Weather resistance is good,it is suitable for desert,salt and other
Chemical corrosion resistance,soil and marine organisms corrosion.
Excellent physical properties,many years experience.
Outer diameter,wall thickness,length can be customized
The material is various, such as Q235B,Q345B, A53(A,B), Gr.B, X42,
X46, X52, X56, X60-- X80,etc
The technology is double-side spiral submerged ARC welded.
The steel grade includes Q235, Q345, J55, X65,X70.
Note:Special design can be customized according to clients’
