Seamless Vs Welded Pipe
Different In Nature
a. Seamless steel pipe: a steel pipe manufactured entirely of one piece of metal with no visible seams.
b. Steel strips or plates are bent and deformed into round or square shapes, then welded into steel pipes with surface seams.
The Characteristics Are Different
a. The largest diameter of a seamless steel pipe is 650mm, and the lowest diameter is 0.3mm. There are thick-walled pipes and thin-walled pipes for various applications.
b. Welded steel pipes: T-welded steel pipes containing Ni offer excellent corrosion resistance in acidic situations. The higher the Ni content in T-welded steel pipes, the better the corrosion resistance in situations containing sulfuric acid or hydrochloric acid. Most of the time, simply adding Cr to the T-welded steel pipe is enough to keep it from corroding.
The Role Is Different
Seamless steel pipes by Stainless Steel 317L Seamless Pipes Supplier are commonly used in petroleum geological drilling pipes, petrochemical cracking pipes, boiler pipes, bearing pipes, and high-precision structural steel pipes for autos, tractors, and airplanes.
Electric welded steel pipes are used in oil drilling and machinery manufacturing, for example; furnace welded pipes can be used as water gas pipes, and large-diameter longitudinally welded pipes are used for high-pressure oil and gas transportation; spiral welded pipes are used for oil and gas transportation, pipe piles, and bridge piers, for example.
