What is SSAW pipe/tube？

1.General introduction

SSAW steel pipe is also known as the Spiral Submerged- Arc Welded Steel Pipe that is a type of spirally welded steel pipe produced by using the double-sided submerged arc welding method. Spiral welded pipes are formed using narrower plates or hot rolled coils, which lowers their production costs significantly. The spiral welding process permits the production of large-diameter pipes suitable for transporting large volumes of oil and gas. Traditional SSAW pipes were historically limited to low pressure applications; however, modern SSAW pipes have been used extensively in Russia, Canada, and Asian countries in high pressure gas pipelines.Generally used: welded pipes convey fluid, metal structures, pile and so on.

2.Application

Our products are widely used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, and spiral submerged steel pipe is one of 20 key products of development. For the transport of liquids: water supply, drainage. For gas transportation: gas, steam, liquefied petroleum gas. For structural purposes: as piling pipe, for bridges; piers, roads, buildings and other structures tube.

JINBAICHENG has overwhelming advantages over cometiotors in manufacturing this SAWH steel pipe.We have 10 traditional one-step production lines and 1 two-step production line that enables to produce finely pre-welded SAWH steel pipe of 36000 tons per year,and we have become the leading enterprise in this industry in virtue of large productivity and advanced technical equipment.

3.Advantage and disadvantage

Since the defect is parallel to the weld, the defect of the weld is an oblique defect for the spiral pipe. In the course of use, the principal stress direction of the steel pipe, that is, the equivalent defect length in the axial direction of the steel pipe is smaller than that of the straight seam pipe; secondly, since the pipeline steel is a rolled steel plate, the impact toughness has a large anisotropy.

The CVN value in the rolling direction can be three times higher than the CVN value perpendicular to the rolling direction. The main stress of the straight seam pipe is exactly perpendicular to the direction of the lowest impact resistance of the pipe, while the spiral pipe staggers the direction of the lowest impact resistance of the pipe, which turns the disadvantage of the long weld of the spiral pipe into an advantage.
