Seamless pipe is a tube that does not have any welding seam. Seamless
pipes are
derived from solid steel that is in sheet or bar form and is formed into a
solid round shape known as “billets” which are then heated and cast over a form
such as a piercing rod to create a hollow tube or shell. Seamless Steel Pipe is made from a solid
round steel ‘billet’ which is heated and pushed or pulled over a form until the
steel is shaped into a hollow tube. The Usage of Seamless Pipe They are generally used for high-temperature and
high-pressure equipment such as high-pressure oil pipes and high-pressure
boiler tubes. Seamless pipes are commonly used in commercial, housing and
industrial walls, labs, several of factories, building infrastructure etc.

difference between seamless pipe and normal pipe? v Seamless
Pipe: - As the name suggests, seamless pipe is a pipe that is
manufactured without any welds or seams. It is typically made by piercing a
solid block of metal and then rolling it into a tube.
v Normal
Pipe: - Normal pipe, also known as welded pipe, is made by joining
two or more pieces of metal together with a weld. There are many different
types of welded pipe, but the most common are electric resistance welded (ERW)
pipe and submerged arc welded (SAW) pipe. ERW pipe is made by passing a sheet
of metal through a high-frequency electric current, which melts the edges of
the metal and fuses them together. Uses and Applications:
Heat exchanger: Heat exchangers often
operate under high pressure and temperature conditions. Seamless pipes, with
their uniform structure and absence of welded seams, can withstand higher
pressure and temperature levels compared to welded pipes. Seamless pipes
provide enhanced structural integrity, reducing the risk of failure over time. Fertilizer industry: The areas of
application in the fertilizer industry primarily include the
following: Melamine plants high-pressure tubes and piping systems
apparatus and heat exchangers of urea synthesis ethylene plants. Fertilizer production
often involves corrosive substances, including acids and other chemicals. Seamless pipes
typically have a smooth internal surface. This smoothness facilitates efficient
fluid flow, minimizing friction and pressure drop.
Automotive industry: In
the automotive field, DMV products are used especially in the following areas:
Other important areas of use are hydraulic braking systems. Seamless pipes are
widely used in automotive exhaust systems. The pipes that transport exhaust
gases from the engine to the tailpipe need to withstand high temperatures,
corrosive gases, and vibrations.
