Thermal and waterproof belt (TWB) of the INNOVATOR® series

Designed to protect the weld from the insecure cooling, protect the pipe insulation from spatter during welding, or when pipe joints heaters are used.

INNOVATOR® TWB is made from modern flame-retardant materials. The carrier materials are glass cloth, aramid cloth (Kevlar ®, Nomex ®), polyester, polyamide, variations of foil and felt (polyethyleneterephthalate, aluminum wool, aramids). The coating materials are silicone, fluoro rubber (Viton ®), acrylic, polyester, adhesives (silicone, polyester acrylate), resin (silicone).

Key advantages:

  • provide a high quality weld during cooling
  • adjustable diameter
  • operating temperature from–60° С to +250° С, no shrinkage
  • water- and vapor-proof
  • fire-resistant, non-stick, anti-adhesive
  • excellent electrical insulating properties
  • elastic at low temperatures
  • the properties remain unchanged during long storage and operation; long lifetime

Pipe centralizers

CZN (ЦЗН) link external centralizers are designed to centralize the pipe ends before welding joints from57 mmto 1420mm in diameter at ambient temperature from 233 to 313K ( -40 to +40ºC).

The centralizer is a polyhedron equipped with press rollers. Master links have hooks and a clamp screw by which the centralizer inner radius decreases thus making the external surfaces of the welded pipes fit.

The centralizers are easy to use and have a light construction, which makes them indispensable when installing or repairing pipelines. The model we offer is made of a lighter alloy, so it is twice as light as similar models made by other manufacturers, which is especially valuable in the field.

Sample manual

Designed to compensate the magnetic flux in pipes during arc welding in field conditions.

The set helps to reduce the magnetic field in a junction to the value of max 20 gauss.
The machine is specifically designed for installation and repair requiring the consistently high quality of welding.

  • Each set of belts includes a set of connecting cables.
  • Upon request, we can manufacture sets of belts for pipes having a different diameter.

Delivery on the territory of the Russian Federationis made by any transport company.

OOO PERMTRANSGAZ SAMPLE MANUAL
FOR MAGNETIC FLUX COMPENSATOR FOR ARC WELDING IN FIELD CONDITIONS

 

the Town ofChaikovsky, 2005





1. General

1.1. This manual is intended for installers, burners and electrical/gas welders who carry out the training and installation of pipe joints for welding. The manual shows the sequence of operations that must be completed before welding a joint to compensate for the magnetic field arising in the pipeline after in-line inspection.

 

2. List of operations to compensate the magnetic flux


2.1. Measure the magnetic field direction with a compass around the perimeter of the joint. To do this, move the compass perpendicular to the junction of the pipe body (see Figure 1).

 

Figure 2. Wiring magnetic flux compensator to DC.Figure 1. Measuring the magnetic field direction with a compass.

2.2. Put the belts on the joint: put the wide belt on the pipe and the narrow belt on the coil (see Figure 2).


2.3. Connect the connectors of the belts so as to form a spiral (make sure that the belts do not face each other).

2.4. Connect the two belts together using a special jumper wire (ensure that the red mark on the belts are located next to each other).

2.5. Connect the extension cable to the welding machine through a ballast resistor; connect pivot ends of the welding cable to the extension cables.

2.6. Set the value of the welding current on the welding machine as corresponding to the machine’s ПН - 100% (about 40 - 80 amps); increase the resistance of the ballast resistor to the maximum.

2.7. Using the compass, check the change in the magnetic field. If the magnetic field has increased, it is necessary to change the pole at the joints with the magnetic field compensator or on the welding machine.

2.8. Keep reducing the resistance of the ballast resistor until the magnetic field in the junction reaches the normal range of ± 20 gauss (the electrode does not stick to the edge of the joint, and welding operations are possible).

2.9. Weld the tacks around the perimeter of the joint. If necessary, repeat steps 7 and 8 for each tack.

2.10. After welding the tacks, perform the necessary steps according to the regulatory process documentation to prepare the joint for welding and weld the root layer.

2.11. After welding the root layer the magnetic blast will disappear, and you can disconnect the magnetic field compensator from the welding machine and weld other layers of the seam.

Note: All persons involved in the compensation of the magnetic flux must be guided by the Rules of Electrical Installations Operation.
