Features of LSAW Carbon Steel Pipes
LSAW Carbon Steel Pipes are carbon steel pipes manufactured using the straight seam submerged arc welding process. The manufacturing process begins with high-quality carbon steel plates, which are subjected to edge curling treatment to form a straight seam butt joint shape. Submerged arc welding technology is used to form continuous and solid welds. This welding process can penetrate deep into the bottom of the weld seam, ensuring good penetration and strength of the weld seam, giving the entire pipeline excellent sealing and pressure bearing capacity.
Employment of the Longitudinal Submerged Arc Welding (LSAW) technique engenders welds of superior quality. It is capable of generating welds with substantial depth and consistent quality, thereby guaranteeing the integrity and leak-proof integrity of the pipeline. This enables the pipeline to effectively endure internal pressure and precludes the leakage of media.
The forming process exhibits a high degree of precision, endowing the pipeline with a regular shape and permitting excellent control over dimensional accuracy. Such characteristics are conducive to subsequent installation and utilization procedures.
Material demonstrates reliable performance. Owing to the inherent properties of carbon steel, its chemical composition can be calibrated in accordance with specific engineering exigencies.
A comprehensive spectrum of outer diameter options is available, spanning from small to large diameters. The wall thickness can be adaptively determined based on the pressure rating that the pipeline is designed to withstand.
It exhibits remarkable yield strength and tensile strength, fulfilling the stringent requirements of diverse engineering structures and fluid conveyance applications with respect to pipeline strength.
Favorable toughness attribute empowers the pipeline to effectively attenuate external impacts or vibrations, thereby diminishing the likelihood of damage.
It commands a wide-ranging application domain:
Oil and gas industry: long-distance pipelines, gathering pipelines, offshore platform pipeline systems
Construction industry: water supply and drainage system, building structural support
In the field of hydraulic engineering: large-scale water conveyance projects, irrigation system pipelines
Chemical industry: Chemical raw material transportation pipelines, chemical product transportation pipelines
