Comparison of straight seam welded steel pipe and spiral Spiral submerged arc welded pipe was spiral distribution, long weld, especially in the dynamic conditions of welding, the weld is too late to leave the molding of the cooling point, prone to welding hot cracks. The direction of cracks and weld parallel, and the steel pipe into an angle, usually between 30-70 °.
Spiral submerged arc (SSAW) is its forward direction and forming tube centerline hose reel molding angle (adjustable), side molding edge welding and weld them into a spiral, the advantage of the same specification to produce a variety of diameter sizes steel pipe, raw materials to adapt to a wider range, the weld can avoid the main stress force
Differences between High Frequency Resistance Welded Pipe 1. Comparison of process characteristics and quality performance of several steel pipes:ERW Pipe is divided into induction welding and contact welding according to different welding methods. Using hot-rolled wide strip steel coils as raw materials, through pre-bending, continuous forming, welding, heat treatment, sizing, straightening, cutting and other processes, compared with spiral welded
Differences between High Frequency Resistance Welded Pipe At present, the most widely used areas are city gas, crude oil and refined oil transportation. Spiral submerged arc welded pipe (SSAW) is a strip steel coiled pipe whose advancing direction has a forming angle (adjustable) with the center line of the forming pipe. It is welded while forming, and its weld is spiral.

How to select LSAW and SSAW in API 5L spec line pipe?According to the forming process, the SSAW pipe has a lot of residual tensile stress (Maximum up to 200 ~ 300 Pa). While in the process of UOE forming process, there is an enlarged diameter. The surface of that compressive residual stress is - 200 ~- 300M Pa. In the process of mechanical expansion, UOE tube has higher dimensional accuracy than SSAW.
LSAW steel pipes vs SSAW steel pipes LSAW steel pipe millOct 05, 2018 · Thought SSAW steel pipe is using the same welding technology of Submerged Arc-Welding with LSAW steel pipes. Differently, the SSAW pipe is spiral welded where the LSAW is longitudinally welded. 5) Application Difference:Application of LSAW steel pipes have been widely used in the oil and gas pipelines, especially required large diameter and
Spiral Submerged-arc Welded Steel Pipe / SSAW Steel Pipe:Usage:Low pressure liquid delivery, such as water, gas, and oil, Offshore Piling Pipe / Port Construction Pipe, Structure Pipe We sell 160,000 tons steel pipes per year, including the steel pipes for the high, medium and low pressure boilers, shipping, transporting liquid products
SPIRAL PIPE CASING SUPPLIER PHILIPPINES - Alberdo Spiral Submerged Arc Welded or SSAW pipes are highly noticeable because of their helical welding seam. Spiral steel pipe casing, which is also called pipe piles and bored pipe casing, is normally used in the foundation of structures that have soft soil. These pipes can also be used in water lines that require big diameter and lengths. Our
SPIRAL WELDED STEEL PIPE - Meever KonnectionSPIRALLY WELDED PIPE SPIRAL WELDED STEEL PIPE Our spiral steel pipe production lines are equipped with advanced automatic double-sided submerged arc welding apparatus which produce the high-quality pipes with high density and permeating defending weld seam.MAIN CHARACTERISTIC:Reliable manufacture method A wide range of steel grades

The Advantages and Disadvantages and Classification of 3, Spiral submerged arc welded pipe features:spiral weld line distribution, long welds, especially under dynamic conditions is in the welding, the weld had a chance to cool and left the molding point, easy to produce welding hot cracking. Direction parallel to the weld crack, a certain angle the axis of the steel pipe, typically between 30-70 °.
The difference between ERW, SSAW, LSAW(UOE) Steel pipe When the spiral submerged arc welded pipe (SSAW) is a coiled steel pipe, its advancing direction has a forming angle (adjustable) with the centerline of the forming pipe, and the edge is welded while forming. The welding seam is a spiral line. The advantage is that the same specification steel strip can be produced. A variety of diameters of steel pipe, raw material to
Spiral submerged arc pipe (SSAW pipe) is its forward direction and forming tube centerline hose reel molding angle (adjustable), side molding edge welding and weld them into a spiral, the advantage of the same specification to produce a variety of diameter sizes steel pipe, raw materials to adapt to a wider range, the weld can avoid the main
What is a spiral steel pipe? - pipelinedubaiSpiral submerged arc welding(SSAW) is its forward direction and forming tube centerline hose reel molding angle (adjustable), side molding edge welding and weld them into a spiral. (Spirally Submerged Arc Welding pipes) SSAW pipes:SSAW pipes are produced by spiral (helicoidal) welding of steel coil and have a cost advantage over LSAW pipes, as the
What is a spiral steel pipe? - ugsteelmill(Spirally Submerged Arc Welding pipes) SSAW pipes:SSAW pipes are produced by spiral (helicoidal) welding of steel coil and have a cost advantage over LSAW pipes, as the process uses coils rather than steel plates. As such, in applications where spiral-weld is acceptable, SSAW pipes may be preferred over LSAW pipes.
What is a SSAW pipe?. Spiral submerged arc welded steel pipe is a kind of metal pipe with spiral seam welded by submerged arc welding technology.. SSAW pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature. All the pipes are produced according to API Spec 5L, GB/T9711.1, GB/T9711.2, ASTM A252-89
