Product Description

Product Description

SSAW STEEL PIPE

SSAW steel pipe is abbreviation of spiral submerged arc welded steel pipe, is a spiral welded steel pipe produced by double-sided submerged arc welding. Spiral welded pipes are formed from narrower sheets or hot-rolled coils, which greatly reduces their production costs. The spiral welding process allows the production of large diameter pipes suitable for transporting large quantities of oil and gas.

Process
Carbon Steel Seamless Pipe UsesIn Spiral Submerged Arc Welding (SSAW) Process, also known as HSAW pipe, welding line shape like a helix. It is using the same welding technology of Submerged Arc Welding with LSAW pipe. Only major difference being SSAW pipe is spiral welded whereas the LSAW is longitudinally welded. Manufacturing process is rolling the steel strip, to make the rolling direction have an angle with the direction of the pipe center, forming and welding, so the welding seam is in a spiral line.
 

Application
Oil and Gas Pipeline, Water Transmission, Liquid Transportation, Building Construction, Steel Structure Construction, Offshore / Onshore Construction, Piling Works, Electricity, Heating Power etc.

ADVANTAGES OF SSAW STEEL PIPE

(1) The use of steel strips of the same width enables the production of steel pipes of different diameters, in particular the production of large-diameter steel pipes with narrow strip steel.

ADVANTAGES OF SSAW STEEL PIPE

(2) Under the same pressure conditions, the spiral welds are subjected to a smaller stress than the straight seams, which is 75% to 90% of the straight seam welded pipes, and can therefore withstand greater pressures. Compared with the straight welded pipe with the same outer diameter, under the same pressure, the wall thickness can be reduced by 10% to 25%.

ADVANTAGES OF SSAW STEEL PIPE

(3) Accurate size, general diameter tolerance is not more than 0.12%, deflection is less than 1/2000, ellipticity is less than 1%, and sizing and straightening processes are generally omitted.

(4) It can be continuously produced. In theory, it can produce infinitely long steel pipes, and the loss of cutting and cutting tails is small, which can increase the metal utilization rate by 6% to 8%.

ADVANTAGES OF SSAW STEEL PIPE

(5) Compared with the straight seam welded pipe, its operation is flexible and the adjustment of the replacement type is convenient.

(6) The equipment is light and the initial investment is small. It can be made into a trailer-type flow unit and the welded pipe can be produced directly at the construction site where the pipeline is laid.

(7)It is easy to realize mechanization and automation.
