ASTM A106 A36 A53 Spiral Welded Black Mild Carbon Steel Tube Round
Square Rectangle Pipe
Advantages of spiral welded pipe:
(1) Steel pipes of different diameters can be produced using strip
steel of the same width, and
steel pipes of large diameter can be produced from narrow strip
steel.
(2) Under the same pressure conditions, the stress of the
spiral welded seam is smaller than that of the straight seam, which
is 75% to 90% of that of the straight seam welded pipe, so it can
withstand greater pressure. Compared with the straight seam welded
pipe of the same outer diameter, the wall thickness can be reduced
by 10% to 25% under the same pressure.
(3) The size is accurate, the general diameter tolerance does not
exceed 0.12%, the deflection is less than 1/2000, and the ovality
is less than 1%. Generally, the sizing and straightening process
can be omitted.
(4) Continuous production is possible. In theory, long steel pipes
can be produced, with small head and tail loss, and can
increase the metal utilization rate by 6% to 8%.
(5) The equipment is light in weight and low initial investment. It
can be made into a trailer-type mobile unit to directly produce
welded pipes at the construction site where the pipeline is laid.
