Bell

Bells of PVC pipes and fittings are equipped in the factory with fixed rubber rings that greatly simplifies installation of the system and makes it possible to achieve more reliable connections.

1. Smooth end of the tube and funnel with a rubber ring should be thoroughly cleaned of dirt, sand and dust. Make sure the rubber ring is correctly located in the hub, have no deflections, bulges. Make sure the smooth tube end is blunted.

2. Lubricate the smooth end of the tube and a rubber ring in the socket with silicone grease. Do not use grease petrochemical oils. Keep on sand or dirt do not get on the greased surface.

3. Point the smooth end of the pipe into the socket. Connecting tubes should be on the same axis (Fig. 2, 3).

4. Insert the smooth end of the pipe into the socket at the depth specified by wiring label , not pushing the tube forward. Compiling is done manually. You can use scrap as a lever (in this case there should be a wooden strip between the scrap and the end of the pipe). 

If efforts of a scrap are not enough, you can use a jack, using bucket or attachment with slings or straps and hand winch as a support.

To prevent damage to the pipe be sure to use a wooden or rubber gasket between the pipe and machinery. You can not stick a tube directly by bucket.

If necessary, you can verify the position of the O-ring in the bell after installation. You should take a metal plate with thickness of 0.5-0.8 mm and place it between the socket and the smooth end of the tube so that it comes into contact with sealing ring. Move the plate in circumference of the pipe, we can determine the position of the O-ring in the bell (with proper installation the distance to it should be the same all the way around).

If necessary at the building area machining of tubes and nozzles (cutting and chamfering) is allowed. Cut and shortening of fittings is prohibited. 

As defective during the installation are rejected::
a) All parts of polyvinyl chloride having a cracked or chipped;
b) Rubber rings, with breaks, not withdrawn by overflow, and not included when lightly pressed in the groove of the bell.
