Seamless Pipe - A brief definition

Seamless pipe is a pipe without a seam or weld-joint. The pipe is extruded, under head, from a solid round 'billet' over a form to be shaped into the hollow pipe.

The seamless pipe is then finished to dimensional and wall thickness specifications to meet specific international standards.

The benefits of seamless pipe

Increased Pressure Ratings

One of the key advantages of seamless alloy pipes is their increased ability to withstand pressure. The weakest point in a welded pipe is the welded seam. Because a seamless pipe does not have a welded seam, it is equally strong around the entire circumference of the pipe.

This makes is easier to determine pressure calculations without being required to take weld quality into consideration.

Although seamless pipe can be more expensive than the equivalent welded pipe, this increased ability to withstand pressure can allow thinner and lighter pipes to be used in certain applications.

Increased Corrosion Resistance

Similar to the benefit of increased pressure ratings, seamless pipe offers increased corrosion resistance when compared to welded pipe, due to the lack of a welded seam. Many of the seamless pipes we supply are in specific alloys used in highly corrosive environments.

Common highly corrosive applications include sour service oil fields, chemical manufacturing and processing plants, sulphur recovery and desalination plants.

Uniformity of shape

Seamless pipe is a continuous extrusion of alloy, meaning that it will have an incredibly accurate round cross section, when compared with welded seam pipe.

In comparison, welded seam pipe is wrapped around another form prior to welding, and then has heat and other variables added in the forming processes, meaning it can never achieve as accurate a round cross section as seamless pipe.

Strength under load and in extreme environments

Pipe failures under load or in extreme environments usually occur at the welded seam. As seamless pipe doesn't have that seam, it isn't subject to those failures. Making it a much better choice for use in demanding environments.

Materials of Construction

We specialise in stocking and supplying seamless pipe in specialist nickel alloys, titanium alloys, duplex and super duplex materials.

Common alloys that we stock include nickel alloy 400, nickel alloy 825, nickel alloy 625, nickel alloy C-276, nickel alloy 600, nickel alloy 800HT, 800H, 800, nickel 201, nickel 200 and a range of titanium alloys.
