API Large spiral steel tube mill line

This pipe mill is used to process the strip into required spiral steel pipe in line with relative national standard by going through uncoling, leveling, edge shearing, forming and welding. Pipe produced can be used in different industries like low-pressure fluid transportation, gas pipeline, electric& heat power pipe network, industrial and construction.

Spiral steel tube usage:
1) high strength pertoleum& natural gas transportation pipeline;
2) low pressure liquid transportation pipeline, city coal gas and water drainage pipe;
3) piling pipe for project construction;
4) steel pipe for industrical structure;
5) other usages
Product quality:

Pipe product of this unit can meet with API-5L standard and GB/T3091-2001 standard.

Features:
A. Be adapted with hydraulically roll-and-shear cutting which makes cutting edges smoothly and without burrs. Process is no sparks and noises, even safety.
B. Be adapted with fixing finalized mold which makes the dimensions of ducting precisely and unite, also process is even stable and speedy.
C. Exchanging different sizes molds then will be convenient for adjusting spiral angle, being adapted with automatic way for better agility and precision.
D. Be adapted with hydraulic presure sytem for achieving feeds, locking, cutting turn-down movements ect.
E. Running for material package, it will run after hydraulic pressre has pressed the materials. Be flexible for adjusting pressure which ensures quality for ducting according to different materials, thickness, and dimension.
F. Carrying out locking. Be adapted with Manos tat for controlling occluded which assures the quality of seaming.
G. Collocating of hydraulic pressure system, using with energy saving, safety and easy going measure etc.
H. Hydraulic pressure adapts constant power variable axial piston pump for energy saving.
I. Overall valve, redactor valve for ensuring stable system pressure.
J. Add-in accumulator, reduces ripple controlling of hydraulic pressure system for even stable.
K. Be adapted with two-way throttle valve which makes movement parts for easy adjust.
