USAGE AND APPLICATION RANGE

2 1/2" High Frequency Pipe Welding Line is mainly used to weld round and square/rectangular pipes. This line utilizes roll forming to process steel strip into various shapes. Using high frequency induction heating, this line is capable of producing section material of various diameters and sizes by squeezing weld seam together into closed shape.

ADVANTAGES

Easy adjustment, good weld seam quality. Rigid machine structure. Easy operation and maintenance.

The forming stand arrangement of this line uses double radius pass design.
