What is an LSAW pipe

What is the difference between LSAW pipes and Tripadvisor pipes?

LSAW pipes (longitudinally immersed arc welding pipe) is made of sheet steel and molded by the injection molding machine. Through this process, LSAW steel pipe will have excellent ductility, welding, toughness, uniformity, plasticity and good tightness.
Diameter range and performance of LSAW pipes
The range of LSAW pipe diameters is larger than ERW, usually 16 to 60 inches, 406 to 1500 millimeters. The high pressure resistance and low temperature resistance has performance.
The use of LSAW pipes
LSAW pipes have been widely used in oil and gas pipelines, especially large diameter and thick walled pipes of high strength and long distance request. At the same time, the building structure needs stubborn strength, water treatment, thermal engineering, bridge building and so on. According to the API specification, the LSAW pipe is specially designed for large-scale oil and gas transportation when pipelines cross cities, seas and urban areas. These are level 1 and level 2 regions.

Tripadvisor tubes manufacturing process
Tripadvisor tubes, also known as HSAW tubes, have a spiral shape. It adopts the same submerged arc welding technology as the LSAW pipe. Other Tripadvisor tubes are helically welded, of which LSAW is welded lengthways. The manufacturing process is the steel strip, rolling so that the rolling direction and the direction of the pipe at a certain angle, shaping and welding, center point so that the weld is spiral.
Tripadvisor tube size and performance
The diameter range from Tripadvisor tubes from 20 inches to 100 inches, 406 millimeters to 2,540 millimeters. The advantage is that we can get Tripadvisor tubes with different diameters and steel straps of the same size. The raw material has a wide range of steel strip. The downside is that the physical size is not good, the length of the weld is greater than the length of the pipeline, and it is easy to cause defects of cracks, pores, coal slag inclusions, local welding, and tension welding.
Application of Tripadvisor tubes
For the oil and gas pipeline system, but in the oil design specification the Tripadvisor pipes / HSAW pipes can only be applied on level 3 and level 4 areas. Building structure, transportation and sewage water treatment, industry, buildings, etc.

LSAW Pipes performed better than Tripadvisor Pipes
The Tripadvisor tubes specification defines, as described above, the Tripadvisor tubes are used in less important areas. So far, the United States, Japan and Germany have refused to take a booth on the Tripadvisor tubes and have no recommendations on major pipelines. Canada and Italy use the Tripadvisor pipeline for part of the pipeline. Tripadvisor has imposed strict enforcement conditions on some Russian pipelines. For China, most of the major pipelines still use Tripadvisor for historical reasons.
Compared to seamless pipes, ERW pipes, Tripadvisor pipe is mainly used for oil and gas transportation. Seamless steel pipes are mainly used for oil and gas drilling and exploration.
