Characteristics of Submerged Arc Welded LSAW Steel Pipe

Characteristics of Submerged Arc Welded LSAW Steel Pipe

Characteristics of submerged arc welded straight seam steel pipe Submerged arc welded straight seam steel pipe body has a longitudinal weld. When the diameter is larger than 914mm, two welds are allowed. Welding wire is used for submerged arc welding. Submerged arc longitudinal weld steel is abbreviated as ASWL, which is a shielded flux weld; The most important feature of submerged arc welded straight seam steel pipe is the use of external welding wire for arc heat melting and the use of submerged arc flux.

What is the difference between the production process of HF LSAW steel pipe and submerged arc welding LSAW steel pipe?

The production differences between HF LSAW steel pipe and submerged arc welded LSAW steel pipe mainly lie in the different raw materials, different molding process, different welding process, different production units, and different production ranges.

Submerged arc welded LSAW steel pipe is the narrowest 1250mm coiled pipe, medium thickness plate and medium thickness plate are the raw materials for production. HF LSAW steel pipe is made of strip steel with maximum width of 1500mm. strip steel is less costly.

The molding process of submerged arc welded straight seam steel pipe is JCOE cold press molding, which is characterized by the gradual molding of steel plates in 50mm increments. J, C, O and E represent the molding process of submerged arc welded straight seam steel pipe.

The HF LSA steel pipe forming process is a cold roll forming process in which the ends of the strip are extruded through multiple rolls to finally align the ends of the strip. It is characterized by uninterrupted forming and continuous welding.

HF straight steel pipe production line is an uninterrupted production line with the same effect, while submerged arc welded straight seam steel pipe has a complete set of intermittent production units for up to 15 processes.

High-frequency LSAW steel pipe has less specification and thin thickness. Submerged Arc Welding LSAW Steel Pipe can be produced in any specification from 325 to 1600mm and any thickness up to 80mm.
