Beta PVC-U Pressure Pipes & Fittings

Share Via

Beta PVC-U pressure pipes are manufactured in conformity with BS 3505:1968 & 1986, BS 3506:1969 and PS 3051:1991. Beta PVC-U pressure pipes are used for drinking water distribution. The high strength-to-weight ratio, coupled with corrosion resistance, makes these pipes ideal for major infrastructure applications. Additionally, we offer customized solutions based on the requirements of our valued clients and possess the expertise to manufacture in accordance with other international standards such as ASTM D1785 (Schedule 40, 80 & 120), ASTM D 2241, DIN 8061/62 & ISO 161.

▪ Resistant to elements injurious to health i.e. free from corrosion, abrasion, growth of
bacteria, algae and fungi.
▪ Installation is easy as the weight is low and the simplicity to join reduces the installation time, which ultimately makes it cost effective.
▪ High flow capabilities since PVC-U pipes are non-corrosive and inert to chemical or
electrochemical resistance.
▪ It does not support combustion.
▪ Thermally and electrically insulated.
▪ It doesn’t affect the taste, odor, or smell of drinking water.

▪ Cold potable water distribution systems
▪ Agriculture, Horticulture and Greenhouse Irrigation System
▪ Tube wells
▪ Fire-ring mains
▪ Effluent pipelines for pumped sewage, industrial and rural wastes.
▪ Slurry pipelines carrying abrasive and corrosive mine or quality material.
▪ Electrical cable safety system.

▪ Solvent Cement Jointing
Solvent cement jointing is a welding not a gluing process. Priming fluid and solvent cements
work by softening the surfaces, so when they are brought together the two PVC surfaces
bond together.

▪ Rubber Ring/Push-Fit Jointing
Push-fit fittings are remarkably easy to use and require no particular skill and no dangerous torches or solvents. The fittings are engineered with a rubber ring of metal spurs inside the fittings that tightly grip the pipes when they are inserted into the fitting sockets. Rubber O- rings inside the fittings form tight, waterproof seals against the pipes.

▪ Mechanical Jointing

Mechanical assembly requires the use of fittings, generally working on the compression
principle. It is normally used with PVC for joining the PVC-U to a pipe or fitting of a different material.

▪ Flange Joint Connection
Flange connection is used for connecting PVC-U pipes to cast iron or galvanized steel or
valves and appurtenances.

Dimensions

Beta Pipes are classified based on their maximum sustained working pressure into various classes, determined by the working stress of the material at 20°C. The maximum sustainable working pressure and field pressure are provided in the table according to BS 3505:1968 and PS 3051:1991.
