Seamless Pipe

A seamless pipe is a pipe that is made of a single piece of metal without any welds or joints. Seamless pipes are stronger, more resistant to corrosion, and can withstand mechanical stress better than welded pipes. They are also able to operate at higher pressures. 

Seamless pipes are made from solid round billets, which are formed through a variety of processes, including:

• Extrusion: A solid billet of stainless steel is heated and formed into a hollow, oblong circular mold. The mold is then drawn through a mandrel rod to increase its length, forming a seamless tube. 

• Hot rolling: A method for manufacturing seamless pipes. 

• Cold drawing: A method for manufacturing seamless pipes. 

Seamless pipes can be used for a variety of purposes, including: 

• Petroleum geological drilling

• Cracking pipes for the petrochemical industry

• Boiler pipes

• Bearing pipes

• High-precision structural steel pipes for automobiles, tractors, and aviation
