Part 3 Line Pipe
Special shaped seamless pipe is the general name given to pipes of any sectional form that is not round. It is widely
used in various structures, tools and mechanical parts.
Compared to the round pipe, it generally has higher moment of inertia, section modulus and bending and torsion resistance
which will greatly reduce the weight of structure and save steel.
square pipe, rectangular pipe, elliptical pipe, light elliptical pipe, semicircular pipe and other more than one hundred complicated
square pipe, rectangular pipe, elliptical pipe, light elliptical pipe, semicircular pipe and other more than one hundred complicated
cross section of ERW and seamless irregular pipe. The suitable material can be carbon steel, high grade steel,
extreme temperature steel, stainless steel, etc.
