Pipes

  • Carbon Steel /Seamless
  • Carbon Steel Welded Pipes
  • Stainless Steel Pipes

Seamless Pipes:

Seamless pipe is a high-tensile steel pipe used under extreme conditions such as those at oil fields and in the transportation of gas. Made by boring a hole through a steel bar and then rolling it, s seamless pipe is considered one of the strongest steel pipes out there today.

Application :

Considered the stronger alternative to welded pipes, SMLS pipes have no seam, hence are capable of withstanding more pressure than welded parts making them the preferred choice in the following industries:

  • Oil & Gas
  • Petrochemical
  • Engineering
  • Power & Water

Advantages:

Due to the very reason that a seamless pipe does not contain any seams, it offers quite a few advantages over welded pipes:

  • Higher pressure ratings
  • Ensures no leaks at the length of the pipe
  • Allows smaller wall thickness to be used due to durability (lack of seam)
  • Most reliable with fewest failure points
  • Less susceptible to bending and breaking
  • More likely to maintain their true round cross-section uniform shape once heated.

Seamless Pipe Quick Specs:

  • Size range: (¼” – 24” )
  • Wall Thickness: Sch. 40 – XXS
  • Length: 6-12-18 Meters Standard
  • Finishing: Plain Both Ends (PBE), Threaded Both Ends (TBE), Beveled Both Ends (BBE)
  • Material: Carbon Steel, Stainless Steel, Alloy Steel, Copper, Cu-Ni Alloys

ERW Pipes

The manufacturing process of an ERW pipe starts of as a flat sheet. This is then rolled up to form a cylinder shape and then welded, hence forming what we know as an Electric Resistance Welded (ERW) pipe.This type of pipe is manufactured using resistance heating to make a longitudinal weld. However, most pipe mills today use HFI (High Frequency Induction) heating for better consistency and control. Despite that, they’re still referred to as an ERW pipe

Application:

While the general consensus in the industry today is that ERW pipes are not as strong as Seamless pipes, they still possess numerous advantages that make them quite a popular product and are used for many different (lower pressure) applications such as the following:

  • Water
  • Pipe Line Construction
  • Pipe Piling
  • Fabrication
  • Utility & Oil
  • Sign Poles

Advantages:

  • Cost Effective Alternative
  • Cheaper to Manufacture
  • Larger OD sizing

Can be rolled to any thickness

ERW Pipes Quick Specs:

  • Size range: (¼” – 24” )
  • Wall Thickness: Sch. 10 – XS
  • Length: 6-12 Meter Standard
  • Finishing: Plain Both Ends (PBE), Threaded Both Ends (TBE), Beveled Both Ends (BBE)
  • Material: Carbon Steel, Stainless Steel, Alloy Steel, Copper, Cu-Ni Alloys

Submerged Arc Welded (SAW)

This type of steel pipe comes in two forms: Longitudinal and Spiral

The manufacturing process of Longitudinal SAW pipe is formed by bending rectangular steel plates that are subsequently welded longitudinally (internally and externally) along the seam to form the pipe. Usually, a longitudinal seam weld is preferred for larger diameter pipes.

As for the Spiral SAW pipe, the pipe is formed by conversion on Hot Rolled Coils and are subsequently welded internally and externally to form a Spiral pipe.

Application:

These types of pipes are mainly used for low pressure liquid delivery such as oil, gas, and water,

  • Onshore and Offshore Oil and Gas Pipelines
  • Conveyance of flammable & nonflammable liquids
  • Structural members in construction
  • Piling Construction

Advantages of Spiral SAW:

  • Large choice diameter
  • Large choice of thickness
  • Stress distribution is even throughout entire pipe lengths
  • High rigidity

SAW Pipes Quick Specs:

  • Size Range: Longitudinal – 16” – 60” / Spiral – 18” – 120”
  • Wall Thickness: Longitudinal – Sch.10 to XS / Spiral – Sch. 10 to XS
  • Length: Longitudinal/Spiral – 6-12-18 Meters Standard
  • Finishing: Plain Both Ends (PBE), Threaded Both Ends (TBE), Beveled Both Ends (BBE)
  • Material: Carbon Steel, Stainless Steel, Alloy Steel, Copper, Cu-Ni Alloys
