The difference between seamless and welded stainless steel pipes
One of the most versatile alloys used in fabrication and
fabrication is stainless steel. SS pipes are widely used in various
industries. Seamless steel pipes and welded steel pipes are the two
most common types of stainless steel pipes
Seamless tubes are made from solid steel sheets or rods that are
formed into solid circular shapes called "bills," which are then
heated and cast over a perforated rod-like shape to form a hollow
tube or shell. It is made of a steel cylinder. After heating the
bar to high temperature, the probe is inserted into the cylinder to
form the hole. It is a circular pipe with a hollow section and no
seams. Seamless steel pipes are made from carbon steel, alloy
steel, stainless steel ingots or solid billets and then rolled.
These pipes are said to be superior to welded pipes because they
are constructed using monolithic billets with inherent mechanical
strength and no seam welds
Welded pipe is a pipe that bends steel strip or steel plate
material into round, square or other shapes with steel pipe joints
on the surface. After that, it was soldered in place. Roll or plate
bending machines are used to cold-form flat strips, sheets or
sheets into round or round shapes. A high energy source is then
used to weld the pipe with or without filler material. Welded pipes
are available in a variety of sizes and can be made to length
The benefits of seamless pipes:
strength
Corrosion resistance
High pressure
Durability
higher material purity
Can be used in critical applications in harsh environments
The benefits of stainless steel pipes:
Cost-effectiveness
faster manufacturing
Easy to customize
consistent concentricity
higher tolerance
Welded steel pipes are widely used in boilers, automobiles,
shipbuilding, furniture, agricultural machinery, scaffolding,
conduits, roof racks, containers and other applications. And
seamless pipes are used in seawater applications, gas and fluid
transfer, chemical lines, oil and gas flow lines, chemical and
thermal processing plants
