Premium Quality LSAW Pipes Supplier from India Tricon Steel & Alloys. These pipes boast unrivalled corrosion resistance and impressive high-temperature strength. Trusted across chemical processing, petrochemicals, pharmaceuticals, and beyond, they epitomise reliability and quality, making them the preferred solution for demanding industrial applications.
LSAW pipe is a large-diameter welded steel pipe characterised by straight threads welded along the length of the pipe. This pipe is manufactured by a submerged arc welding system, where a combination of pressure and heat is applied to fuse metal plates.
The key feature of LSAW pipelines is high efficiency and stability, making them suitable for long-distance transportation of various liquids and gases. They are commonly used in oil and gas transportation, water supply, and construction projects requiring great pipelines.
LSAW pipe offers many advantages over other types of welded pipe. Their straight weave ensures uniform wall thickness, increasing the pipe's structural integrity. In addition, the welding process allows precise control of pipe dimensions and tolerances, ensuring consistent quality and efficiency.
LSAW pipe finds extensive application in onshore and offshore applications. The oil and gas industry transports crude, natural gas and refined products from production to processing and distribution sites. Their size and high carrying capacity make it ideally suited for this complex application. In addition, LSAW pipes are used in infrastructure projects such as bridge construction, piling, and construction support due to their ability to withstand heavy loads and harsh environmental conditions.
Testing is an important part of ensuring the quality and reliability of LSAW pipelines. During and after the process, tests are conducted to evaluate factors such as weld integrity, mechanical properties, dimensional accuracy, etc. These tests may include ultrasonic testing, hydrostatic testing, radiographic testing, and visual survey. Ultrasonic testing is especially important for detecting defects in the weld zone, while hydrostatic testing controls the strength and leak-tightness of the pipe under pressure.

The Rolling and Welding Stage
To begin our process, we first need to go through the rolling and welding stage. The Carbon steel is placed through a checking process and cut at the edges in this stage.
Cleaning and Warming Stage
The rolled Carbon steel pipes thus manufactured are cut to the required lengths depending upon the industrial demand.
Cold-Drawing Stage
Sometimes, the required size isn’t obtained when the steel is brought through the mill directly. When using the cold-drawing process, the desired size is achieved when the pipes and tubing are coated with oxalic and soap solution and dragged over die plugs—the oxalic and soap solution help reduce friction when going through the cold cycle.
The Finishing Process
The final process is the finisher. Once the process of manufacturing LSAW Pipes and tubing is completed, you’ll now have to take them to a jet printer.
