Seamless pipes can be manufactured to fit the different needs and specifications of the client. Seamless pipes are made with no weld and no seam.

The main methods for manufacturing seamless pipes include

  1. Hot Rotary Piercing
  2. Extrusion Process Method

Hot Rotary Piercing

This is the most common method. The manufacturer first forces the steel through a piercing mill. Then a hot, solid, round billet pushes through the center to make the pipe hollow. The machine uses a piercing plug to create the hole.

Extrusion Process

Hot billets go through extrusion dies. Then, a metal bar in the machine, known as the mandrel, forms the billets. This forms the seamless pipes.

How to transport seamless steel pipes?

The pipes must be packaged and shipped carefully. This will prevent damage to the pipes. The pipes must also be sealed from too much moisture when packaging them in bundles, especially if they have a smaller diameter. This could cause the ends of the pipe to rust.

Seamless steel pipes are typically exported by sea but can be transported in bundles by truck to job sites. A checking process occurs before the good is ready for export. In this process, a few things must be reviewed during packing and labeling. This may include breakage, security, excess weight, and proper identification markings. Another typical requirement for exporting is an export license.

Where to Buy Seamless Steel Pipes?

You may be able to find seamless steel pipes in small quantities in your area. But if you want to buy large quantities of seamless pipes, it is preferable to import directly from the manufacturers. They can issue certifications and provide cost savings which is better than buying the steel in small quantities locally or from a distributor.
