ADVANTAGES OF SPIRAL-WELDED STEEL PIPE

WIDE RANGE IN DIAMETER AND WALL THICKNESS

We manufacture spiral welded steel pipes with diameters ranging between 100 mm – 3,600 mm and in standard thicknesses between 3.4 mm – 25 mm. This means savings on the part of the customer as the customer can select the right size and wall thickness to meet exact design requirements.

INFINITE LENGTHS

IPI can manufacture pipes in any desired length; as long as the pipe length is capable of being transported from our manufacturing plant to client site.  However, fewer joints required in pipe lines will  result to lower handling, laying and jointing costs.

PERFECT ROUNDNESS AND STRAIGHTNESS

The spiral method of forming and manufacturing  IPI pipes, means roundness and a straightness of pipe formed, compared to other means of production. This is due to the regularity inherent in the spiral forming of the pipe, and the fact that shrinkage of the welding is uniformly distributed throughout the length of the pipe.  Such perfect concentricity makes it easier to weld two pipes together, which proves to be of great advantage particularly in pipe lines and piling applications.

GREATER STRENGTH

The double welded seam has the effect of a spiral band around the IPI pipe, which significantly increases its strength.

EVEN THICKNESS

The pipes are manufactured from strip with minimum tolerances which produces a thickness that is perfectly uniform over the entire length of the pipe.

THINNER WALL

The double welding spiral process makes it possible to manufacture thin-walled large diameter pipes used for pipe lines, piling requirements, or structural projects. This means savings on raw material steel thereby making the pipes cost effective.

GREATER RESISTANCE TO PRESSURES

The IPI spiral-shaped double-welded seam pipe has as an effect of adding greater structural strength which can withstand 25% higher pressures than longitudinally welded pipes of equivalent wall thickness.

TEST AND INSPECTION

All IPI pipes undergo several quality control tests such as: material control tests, hydrostatic pressure tests, and inspection by ring gauges and X-RAY tests.  Aside from the standard quality testing foregoing routine procedures, IPI statistically selected sample pipes are also subject to destructive testing by third party quality inspectors to validate quality of IPI manufactured pipes.

FLEXIBILITY

The spirally welded IPI pipes are easy to bend compared to seamless or longitudinally welded tubes of equal diameter, wall thickness and basic material quality.

GOOD WELDABILITY

The good welding properties of IPI raw material ensures smooth manufacturing process. The weldability of IPI pipes makes it easy to use IPI pipes at construction sites.
