Extrusion line for polymeric packing production was started up in Belarus

Carnevalli together with Terra Print have realized a large project in the field of plastic film production — the extrusion line Carnevalli Polaris COEX 3 PO was opened up at BZPI.

Polypropylene pipes and fittings for inner hot water and cold water supply

Pipes and fittings made of polypropylene “Random copolymer” are used for inner hot water and cold water supply conduits and for industrial pipe-lines. Pipe-line made of PPRC is a remarkable decision for internal wiring of cold and hot water supply.

Polypropylene pipes from the Borisov Plastic Products Plant are produced from high-quality propylene of modern generation – random copolymer BOREALIS RA 130E.

Random copolymer (type3) is a modification of polypropylene, which supplies with better characteristics and, first of all, continuous firmness to high temperature and pressure. Pressure conduits made of this material gave an excellent account of themselves during 1980s and 90s in many developed and developing countries. They can be considered to be an optimal industrial solution in our conditions: modern, ecologically neutral, long-lasting supply and heating systems, which allow to replace traditional steel wiring – by parts as well as entirely – with minimum expenses.

The reason for PPRC pipes success primarily is in material properties. First of all, polypropylene is absolutely non-toxic: even if to bring it to fire, only carbonic acid and water will escape. Secondly, this material is not sensitive to high temperature and pressure. With good safety margin it withstands common for water supply loads.

Polypropylene pipes, in comparison with steel pipes, have much plainer inner surface and possesses minor thermal conduction. Owing to these properties, PPRC pipes are notable for lesser pressure and heat loss. Condensate is not generated so abundantly on cold water pipes, and it is required less insulating material for lagging arrangement. When fluid in PPRC pipes is congealed, they don’t destroy, but enlarge in diameter and reacquire the previous size when defrosted.

One more attractive characteristic of PPRC pipes is the bounding technique. Fittings and stop valve are produced not from expensive non-ferrous metals, but from the same polypropylene. Sleeve welding used for assembling is highly a simple technology, and anyone who wishes is able to master it. Pipes are bounded by means of contact thermal welding. Special combined details allow to join polypropylene pipes with metal pipes.

The relative drawback of PPRC pipe-lines is sufficiently high thermal-expansion coefficient. The given problem is solved by compensator usage.
