Plastic Welding Machines & Equipment


Welding machines for plumbers and constructors of installation plants

WIDOS Miniplast/2
The Miniplast/2 is a welding machine for heating element butt welding of PE, PP and PVDF pipes and fittings from OD 20 to OD 110 mm. The basic machine has two large aluminium basic clamping tools which are swivelling up to 15° on each side for the fabrication of segmented bends. By screwing in 4 small reduction inserts, a double clamping is obtained at the smaller diameters. For fittings with short legs, a small fitting clamping tool is available.

Due to the special construction of the pressure build-up device, the machine can be fixed directly at very short pipe ends on walls and sheets. Due to its light and compact construction as well as due to the horizontal and vertical motion, the machine is ideally suited for use in the pipeline system and for installation work. In the case of stationary use, the machine can be fixed in the vice or at the table support.

Accessories

mural flange

The WIDOS mural flanges out of EPDM can be applied in all areas where pipelines are guided through masonries, walls and floor panels. In case of water, ground water or an increased ground water level in areas of water streams and rivers, the mural flange which is placed on the pipe in the middle of the masonry protects the building against permeating humidity. When dealing with swimming pools and floor pans, the mural flange protects against leaking water resp. the underground against leaking liquids.

At the interior wall of the flange, densely fitted key ribs are placed especially for uneven pipe surfaces. The mural flange is 70 mm wide and warrants a safe halt with all pipe materials. In case of extreme mounting conditions, the highly minted profile depth at the leak-proof flange provides a solid halt in the filling material. The revolving groove externally inserted on each side provides a correct fit and mounting of the non-corrosive clamping belts. The elasticity of the mural flange permits a mounting on pipes out of plastic, stoneware, concrete, casting iron, steel and coated pipes.
Available for pipes from OD 32 up to OD 400, larger dimensions on request.

casing tube

WIDOS casing tubes are manufactured from a special non-asbestos polymer quartz cement and appropriate for the installation in wall and ceiling. By the great amount of selected filling materials like quartz sand, stone flour and cement that are bound by a special polymer resin, these casing tubes build a very good interconnection with concrete. They are resistant to pressure water and by using proven material appropriate for the application in drinking water facilities. Due to high quality materials it is possible to reach optimally mechanical properties in comparison to conventional fiber-cement components, especially high load capacities of impact and peak pressure. WIDOS casing tubes are equipped with an exterior wall creasing which results in an additional protection against water permeation due to capillary attraction. The groove resembling shape and the dimensioning of the fittings correspond to the factory standard of one of the largest German water suppliers. The interior diameters of the casing tubes are between 80 mm and 300 mm and available in lengths of up to 1000 mm (other dimensions on request). In case of a supplementary installation, the casing tubes are longitudinally divided.

ring seal

Before leading pipelines or cables through external walls being above or below ground level, through ceilings or in so-called sheath tubes, it has to be made sure that the lead-through areas are permanently sealed. Neither pushing water nor gas may permeate by the lead-through of the building resp. the protective pipe sealing.
WIDOS Ring-Seal lead-throughs of buildings and sealing inserts enable simple, quick and clean lead-throughs of pipelines and cables through walls, ceilings and sheath tubes. The sealing inserts are designed in pressure-tight form in two steps (20 mWS / 50 mWS) and additionally prevent a transmission of heat and sound.

sani pipe refurbishment

With WIDOS SANI-Pipe you can securely and permanently seal problematic places/passages from media pipe to underground. Since the elements are not mechanically fixed but fastenend with an especially flexible system glue, there is no direct transmission of the forces which are caused by movement of the media pipes. They are shaped in a way that transmitted tensions are absorbed. Even in case of a strong load capacity no cracks will appear within the sealing elements. At the glued joints no tensions will appear that might interfere the fixation and lead to an underflow.
At the same time, the system glue provides an effective sealing against water due to its excellent adhesive properties. Fixing and sealing of the SANI-Pipe elements is only made in one time saving working step. A further advantage is that they can be also fixed where water lines up - outside on the sealing level. Water cannot thus permeate the component at all. It is already effectively stopped in advance. The outer fixation of the SANI-Pipe elements (out of solid hard plastic) offers an additional protection for the lead-through, especially when using annulus gaskets.
