Introduction Strangling clip of PE pipeline
Strangling clip PE pipeline DN 25-90 mm ŠS25-90
Technical description of the equipment
The equipment is intended for a temporary strangulation (stopping of Media flow) of PE pipeline SDR 11 (heavy row) DN 25, 32, 40, 50, 63, 90 mm and SDR 17,6 (middle row) DN 90 mm,
of PE 80 material and PE 100 below an operational overpressure of Medium.
The working principle of the equipment is: mechanical compression of a pipeline between two steel cylinders. The lower cylinder is removable and makes it possible to set
strangling clips on uninterrupted line of a pipeline. The upper compressive cylinder has got two rotary limiting segments with a bullet detent in positions for individual
dimensions of a pipeline. The pipeline strangulation is provided by turning of a spindle after holding of a movable forehammer handle. Displacement of an upper
compressive cylinder to the positron of determinated by segments is made by a shaft, equipped with a rolled scroll - TR26x5. Limit segments provide an interruption of a Medium flow
and at the same time those obstruct the excessive burst of sides of a pipeline. The compressed place of a pipeline after removing of a strangling clip is necessary by return
to shape and repair by the electro-shaped piece by the help of a rounder. The equipment has got a surfacing - movable parts - a zinc coating and a frame with guiding stirrups - a
cartophoresis painting.

The construction is designed with regard on necessity of exclusion of a possible deformation of supporting parts at the excessive constriction. The weight of the equipment is 8,2 kg. The service is provided by one person.
Service instructions
- Turn the lower cylinder to the removable position and take out the cylinder.
- Push out the upper cylinder to the top position by turning of a screw spindle.
- Set both of limiting segments of the upper cylinder to the position in accordance with DN of the compressed pipeline by moving round (for DN 32 and DN 25 there is a common position).
- Put a clip on the pipeline, insert the lower cylinder and adjust the position of the clip so that the axis of the pipeline is in the centre of both compressed cylinders.
- Compress the pipeline to the segments determinated position by turning of the screw spindle and holding of clip stirrups.
- Continuously check a clip tightening, especially before the working act on the pipeline.
- Release the strangulation of the pipeline by spindle turning (left) and by rolling out of the upper cylinder to the top position.
- Turn and take out the lower cylinder and take off the clip out of the pipeline.
- The compressed place of the pipeline is necessary to shape by the rounder and repair by the electro-shaped piece.
- Save and transport the equipment in position with tightened cylinders.
- Do not use the equipment with a dirty screw, before the manipulation is necessary to clean it up.
- Lubricate by an oil instillation to the nut of the screw. Do not use a lubricant grease.
