Pipe plugs mechanical models: WA.GP-Z plugs may be utilized as flow stoppers or have a by-pass fitting for by-pass or vent relief.
Working pressures will depend on the diameter of the pipe. All large pipe plugs must be secured with bracing or friction fit bolts, to insure against possible displacement.
Mechanical pipe plugs block pipeline flow pressure for maintenance procedures, they are gas and and water tight.
Reinforced plates allow higher higher pressures on the plugs, once placed and braced mechanical plugs do not require constant monitoring.
Rim seals may be expansion modular seal links or compression disk seals, seal material is EDPM or NBR.
Mechanical pipe plugs have advantages over pneumatic pipe plugs for longer term maintenance projects. They are left in place for the duration of the project and require less monitoring.
Plugs requiring diver installations have designed internal air chambers for buoyancy assistance. Pressure resistance depends on the plug diameter and physical construction of the plug.
Mechanical seals pressure resistance depends on the diameter and type of plug being used.
Pipe Plugs mechanical - 8" diameter and greater.
- The rim seals may be EDPM, or NBR elastomers for oil/gas related projects.
- Mainframes may be 304L stainless or 316L stainless.
Our experienced staff can provide solution guidance and recommendations
Pipe Plugs mechanical for pipe diameters 8" or less.
Mechanical pipe plugs WA.GP-Z for small diameter pipes may be fixed in place for extended work periods.
The seal elastomer is EDPM (other elastomers are also available). The compression plates are corrosion resistant 304L stainless. (316L is also available)
WA.GP-Z plugs may be fitted with a by-pass opening. Fits all American or International pipe sizes up to 8 inch, 200 mm.
Mechanical plugs can seal wall openings for future pipe passage into a building.
Mechanical pipe plugs WA-GP-Z-DL up to 28 psi ( 2 bar) are available, the units have a double seal.
Low Pressure gas pipe line flow stoppers, with NBR elastomer seals.
Mechanical Gas pipeline plugs can be used for PVC or steel pipes.
Mechanical model plugs with stainless steel, aluminum or steel plate.
Mechanical plugs with annular pneumatic seals are a cost effective way to plug pipes. The elastomer expands against the pipe wall for an effective flow stopper.
Available in a range of diameters and configurations.
Inflatable test plugs WA-Pipe Plugs: are one piece construction, thick wall multi-use test plugs, durable and safe for the temporary blocking of pipelines. They have 2-3 times thicker rubber than other plugs.
Plugs are made with one piece elastomer - no welds.
Units are fiber reinforced for high strength with excellent resistance to wear and organic solvents. Plugs are made from natural rubber having a thickness of no less than 10 mm which is two to three times thicker than comparable products.
They are thoroughly tested on all possible aspects before being delivered to our customers insuring a safe working environment.
Inflatable Pipe Test plugs WA-PP units, are equipped with one or more flow through valves. The plugs are suitable for carrying out pressure tests with water or air in accordance with local standards.
The plugs can be used for bypass functions as well as pipeline testing. They are very robust and the couplings are of the high quality for a no leak around seal.
Inflatable Pipe Plugs
Plugs are constructed with consideration for the safety of installers and personal working in or near the lines. Unique and specific production process guarantee safe and durable pipe plugs.
Test pipe plugs - NBR rubber
Onshore - Offshore applications.
NBR rubber has a much better resistance against oil instead of natural rubber and suited to off-shore applications.
Resistant to oils, greases , hydrocarbons and dilute acids makes this plug particularity suitable for industrial sealing.
Plugs are completely made of nitrile rubber (NBR) and reinforced with Aramid © cording. They are designed with a safety factor of 4x maximum pressure. For priority safe installation.
NBR rubber test pipe plugs are equipped with one or more flow through. These test pipe plugs are suitable for carrying out pressure tests with water or air in accordance with the local standard/Nitrile test pipe plugs can also be used for a bypass function as well.
NBR is resistant to oils, greases , hydrocarbons and dilute acids. This makes this plug particularity suitable for industrial or Petrol Chemical pipeline sealing.
Please note that the chemical resistance will depend on various factors such as: the type, the temperature, the concentration, the duration of the contact. The operating temperature is limited to approximate. 100°C.
