PIPE PIPE Canada, Australia, Philippines Service | Metalok360
METALOK360 specialises in pression pipe bending with end-to-end pipe connection solutions.
METALOK360  can minimise your plant shutdown time during pipe installation periods. We prefabricate, precision bent pipes with  “Weldless” or “Welded” connection systems. The advantage to our pipe systems is that we reduce the overall cost of pipe installations, by reducing the number of total welds, compared to fully welded pipe systems.  
METALOK360  produces repeatable, accurate pipe bends up to 6” (154.2mm) diameter, with pipe schedules  from SCH10 to XXS . We achieve high quality complex and repeatable pipe bends by using state of the art hydraulic CNC pipe benders. To round off our service, METALOK360  can also fabricate larger size pipe, from 8” and above, using induction bends, standard weld fittings and flanges, including our end-to-end fitting solutions which are a combination of weldless and fully welded.

All pipe systems are custom built, this ensures that you have  a hassle-free pipe installation that fits first time. METALOK360 can help you reduce installation costs by reducing the number of welds required on a pipe or pipe installation.
METALOK360 offers complete end to end pipe connections on onsite with our  weldless systems, which is “COLD WORK”. Learn more about our “Weldless Connection System”
METALOK360 also offers flexibility to clients by supplying green end pipes and end fittings that can be welded on site. This ensures 100%  flexibility for our customers.

Metalok360 can bend and fabricate pipe assemblies and systems from the following materials-
  • Carbon Steel
  • Stainless Steel
  • Duplex
  • Super Du[plex
  • CUNi
METALOK360 only sources quality pipe from reliable suppliers, ensuring the best products and quality for our clients.
Size & Dimension

Pipe Dimensions are covered in following Standards

ASME B36.10 – Welded and Seamless Wrought Steel Pipe (Carbon & Alloy Steel)
ASME B36.19 – Stainless Steel Pipe

Three different terms are commonly used to define the size of the pipe.

1. NPS – Nominal Pipe Size All American standard used NPS designation to define pipe size. This is a modern derivation of earlier IPS – Iron Pipe Size. NPS is not an OD or ID of the pipe it is in-between of the outer and the inner diameter of the pipe. For example, NPS 2 size pipe outside diameter is 60 mm or 2.375 inches. In general, NPS 12 and the smaller pipe has outside diameter greater than the size and for NPS 14 and above size pipe outside diameter is the same as the size in inches.

2. NB – Nominal Bore This is the European equivalent of NPS. In this standard pipe sizes are mentioned in millimeter

3. DN – Diameter nominal

In the below table, you can see the correlation of pipe size and OD.

NPS 1 1 ½ 2 3 4 6 8
NB / DN 25 40 50 80 100 150 200
OD in mm 33.4 48.3 60.3 88.9 114 168 219

ASME B31.3 provides the list of material that can be used in Process Piping. in below table, you can see the most commonly used material types & their Grades.

Carbon steel Used up to 425°c Stainless steel Used for corrosive fluid Low alloy steel Used for temp > (425°c) Low temp carbon steel Used for temp < (-29°c)
A53 Gr B
A106 Gr B
A312 Gr TP304
A312 Gr TP316
A312 Gr TP321
A335 Gr P2 , P12, P11, P22, P5, P9 A333 Gr 6

Duplex stainless steels are typically used in:

  • Chemical processing, transport and storage
  • Oil and gas exploration and offshore rigs
  • Oil and gas refining
  • Marine environments
  • Pollution control equipment
  • Pulp & paper manufacturing
  • Chemical process plant

Heat Resistance
The high chromium content of duplex stainless steels that protects against corrosion, causes embrittlement at temperatures over about 300°C.

At low temperatures duplex stainless steels have better ductility than the ferritic and martensitic grades. Duplex grades can readily be used down to at least -50°C.

Copper Nickel tubes, CUNI
Application range: Copper-Nickel Alloy tube for condenser and heat-exchangers, Water Evaporators, Boiler Blowdown Heat Exchangers, air coolers, Gland Steam Condensers, Steam Ejector, Turbine Oil Coolers, Fuel Oil Heaters, Compressed Air Inter and After Coolers, Ferrules, Oil Well Pump Liner, and Distiller etc.

Copper Nickel tubes, CUNI 70/30 – C71500 – has, in general, the best resistance of any of the copper alloys to impingement attack and to corrosion from most acids and waters. It is being used in severe corrosive conditions in which service lives longer than those of other copper alloys are desired.
