API 5L LSAW Steel Pipe
Product Overview
API 5L LSAW pipe is longitudinal submerged arc welded steel pipe produced in accordance with API 5L standards. It is the core material for high-strength, high-standard long-distance oil and gas transmission pipelines.
Under official API industry specifications, this pipe type is the only certified pipeline material for large energy transmission projects crossing Class 1 and Class 2 high-risk areas, such as frigid alpine zones, seabed subsea environments, and densely populated urban zones with strict safety limits.
Core Product Advantages
The pipe is manufactured with mature submerged arc welding technology, adopting two-stage welding flow: pre-forming welding and finish welding. This stable production process ensures perfect weld seam quality. Stable welding performance Submerged arc welding forms uniform defect-free weld joints, greatly improving the structural safety of long-distance pipelines. High production efficiency Automated welding lines support mass production, making LSAW pipes the ideal material for heavy steel structures including pressure vessels and pipeline spools. Excellent comprehensive mechanical property It passes strict pressure, impact and fatigue tests to fit various harsh construction conditions.
Overseas Engineering Project Case
Project Name: Paira Bridge (Lebukhali Bridge), Bangladesh Completion Year: 2017 Main Material: ASTM A36 structural steel and matching API 5L LSAW steel pipe Project Scale: The total bridge length is 1470 meters, including auxiliary access roads and river bank anti-scour protection works along the 26km section of Borissa-PATUAKHLI National Highway N-8. Our structural steel and steel pipes were supplied for this large cross-river transportation project, which fully proves the stability of our products for international heavy engineering projects.
