3/4 Schedule 10 40 Standard Pipe ERW Iron Pipe 6 Meter Welded Steel Pipe
Our company also known as welded pipe, is a steel pipe made by
welding steel plates or strips after being rolled and formed.
Welded steel pipes are divided into straight seam welded pipes and
spiral welded pipes according to the form of welds. Classified by
production method: arc welded pipe, resistance welded pipe,
(high-frequency, low-frequency) gas welded pipe, furnace welded
pipe. The production process of straight seam welded pipe is
simple, with high production efficiency, low cost, and rapid
development. The strength of spiral welded pipes is generally
higher than that of straight seam welded pipes. Narrow billets can
be used to produce larger diameter welded pipes, and billets of the
same width can also be used to produce welded pipes of different
diameters. However, compared to straight seam pipes of the same
length, the weld length increases by 30-100% and the production
speed is lower. Thick wall coil products include: large coil, large
diameter thick wall coil, various materials thick wall coil, hot
rolled thick wall coil, cold rolled thick wall coil, etc.
All welded pipes can be made into galvanized welded pipes, which
can be found through product consultation on the homepage
