DB28 High-frequency Tube Welding

Carbon Steel Tube Mill line Product Descriptions

This DB25 Welding tube machine line is specially used for producing carbon high frequency welded pipe mill. This welded machine line is specially used for producingΦ8-Φ23mm, δ0.2-1.3mm high-frequency straight seam welded pipe and corresponding square pipe and special-shaped pipe(δ≤1mm). It made by refined materials in high precision and equipped with fixed length cutting saw. The main machine includes forming, welding, sizing and straightening device. The composition of equipment is from decoiler to fixed length-cutting saw. Rolling speed can be adjusted correspondingly within suitable range of pipe diameter and wall thickness.

At first, the coil is loaded at the uncoiler, then but-welding the ends of coil, delivering to accumulator. After accumulator, the strip is pulled from accumulator contentiously by fixed speed, is formed to opened-pipe at forming machine, then welded by High frequency welder, deburred, cooled, shaped and sized as round pipe and rectangular&square pipe at the sizing area. Then the sized pipe is straightened after Turkey-head device and then cut to fixed length by flying saw. At last, the fixed pipe is delivered from run-out table and inspected at the table.

Application picture
The blanks used for welded steel pipes are steel plates or strip steels, which are divided into furnace welded pipes, electric welded pipes and automatic arc welded pipes due to different welding processes. Due to the different welding forms, it is divided into straight seam welded pipe and spiral welded pipe. Because of its shape, it is divided into round welded pipes and special-shaped (square, flat, etc.) welded pipes.
