Product Description
LSAW(Longitudinally Submerged Arc Welding) Pipe can be divided into UOE and JCOE pipe according to their processing methods. LSAW steel pipe has the characteristics of relatively simple process and fast continuous production, and has widely used in oil and gas, water transmission, engineering, offshore projects.
Process
The three main forming steps of the UOE LSAW pipe forming process include: steel plate pre-bending, U forming and O forming. Each process uses a special forming press to complete the three processes of steel plate pre-bending, U forming, and O forming in sequence, so that the steel plate is deformed into a round tube.
After several steps of stamping on the JCO forming machine, first half of the steel plate is pressed into a "J" shape, and then the other half of the steel plate is pressed into a "J" shape to form a "C" shape, and finally an open "O" is formed by pressing from the middle Type tube blank.
Application
LSAW steel pipe is widely used in the energy field due to its advantages such as high strength, good pressure resistance, and high dimensional accuracy. It is the main pipe material for long-distance oil and natural gas pipelines, ensuring a stable energy supply. It is also used in cooling water pipelines and coal pipelines in thermal power plants, helping develop the power industry.

Using high-quality steel as raw materials, it is processed through strict quality control and advanced production technology. It has high tensile strength and yield strength, can withstand large pressure and load, and is suitable for various high-pressure transmission and load-bearing scenarios.
The stress distribution of its straight seam structure is relatively uniform when it is under stress. Compared with other pipes such as spiral welded pipes, it is not easy to have stress concentration, which further enhances the overall structural stability of the pipeline, prolongs its service life, and reduces maintenance costs.
Usually, professional surface treatment is performed, such as sandblasting and rust removal, coating with anti-corrosion coatings, etc. These coatings can effectively isolate the pipeline from contact with external corrosive media, greatly improving the corrosion resistance of the pipeline.
Adopting advanced production technology, the dimensional accuracy of the pipeline can be accurately controlled, including parameters such as pipe diameter, wall thickness, length, etc., with small dimensional deviation and a strict tolerance range within the standard range.
The characteristics of high strength, corrosion resistance, and reliable welding quality make the service life of LSAW pipes relatively long. Under normal use and maintenance, it can operate stably for a long time, reducing the replacement frequency and maintenance cost of the pipeline.
