Introduction:

Seamless pipe is made from a round steel billet (solid cylindrical hunk of steel that is cast from raw steel). This billet is then heated, stretched out and pushed or pulled over a form. It is then pierced through the center with a die and mandrel which increases the inside diameter and reduces the outside diameter. Even though seamless pipes are manufactured in a variety of sizes, with an increase in pipe diameter the production cost increases. The name seamless comes from its absence of a seam. Seamless pipes are widely used in process piping, power piping, shipbuilding, pressure vessel, construction, and chemical industries.

Advantages

• Strength: Seamless pipes have no seam. This means that the chance for a ‘weak’ seam is eliminated and therefore seamless pipe can typically withstand 20% more working pressure than welded ones of the same material grade and size. The strength is possibly the most significant benefit of using seamless pipe.
• Resistance: The ability to withstand higher resistance is another benefit of having no seam. This is because no seam means there is very little chance for impurities and defects to occur as they more naturally occur along a weld line.
• Less Testing: Having no weld means that seamless pipes don’t need to go through as much rigorous integrity testing as their welded counterparts.
• Less Treatment: Some seamless pipes don’t require heat treatment after manufacture as they harden during the process itself.
