API 5L Line Pipe steel is a building material composed of chemical components such as silicon, sulfur and phosphorus.
API 5L Line Pipe can be used F, b, z were expressed as boiling steel, semi-static steel, killed steel. Boiling steel is incompletely deoxidized steel with poor plasticity and toughness. With welded structures made of this material, joints are prone to cracks when subjected to dynamic loads. It is not suitable to work at low temperatures, sometimes hardening. In contrast, the calm steel has excellent quality and good plasticity and toughness.
API 5L Line Pipe is widely used in construction and engineering structures. It is used to build plant houses, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc., and is also used as a mechanical part that does not require high performance.
