INTRODUCTION
The main raw material of PVC-U piping network is PVC resin, which is added moderate stabilizer, lubricant, fillers, and toner. After the process of mixing, extrusion, sizing, cooling, and cutting, the PVC-U pipe can be made. The PVC-U fittings are made by injection. The PVC-U material doesn’t readily conduct electricity, which can undertake more than 25KV voltage. The PVC-U material has very good chemical properties, physical property and insulating property, which can suit for most of the normal insulation protection application.
This series of PVC-U insulting electrical pipes and fittings are suit for the standard PNS 14 and JG 3050.
FEATURES OF PRODUCT
High Insulating Property:
PVC-U material resists the electricity, which can undertake more than 25KV voltage.
High Impact Resistance:
This material of pipes and fittings can suit to be laid in the concrete.
Non – flammable:
PVC-U material has high limiting oxygen index, which is very difficult to burn, and has died out by itself, when it is away from the fire.
Corrosion Resistant:
PVC-U material has strong resistance to most of acid and alkali. No rust, no antiseptic treatment. The service life is 4 times than that of cast iron.
Light Weight and Easy Installation:
Weight is very light. The density of PVC-U is only 1/5 to 1/6 of that of cast iron. The method of connection is very simple, and the process of installation is very quickly.
High Tensile Strength:
PVC-U has high tensile strength, and high shock strength. The piping network of PVC-U is not easy to break, and it works safety.
Long Service Life:
The piping network with normal material can be used around 20 to 30 years, but the PVC-U piping network can be used longer than 50 years.
Cheaper Prices:
The prices of PVC-U piping network are cheaper than that of cast iron.
FIELDS OF APPLICATION
Piping networks for power or lighting in building.
Piping networks for being laid in the concrete or wall.
Piping networks for post, telecommunications, and network cabling.
