  • Pipes can also be offered as per DIN 8062, ISO 4422-2, BS 3505/6.

For HOT & COLD Water Application

Corrosion resistance:

SAGAR CPVC Pipe gives excellent resistance even under the harshest of water conditions so there are none of the purity worries from corrosion of metal pipe or soldered joints. SAGAR CPVC Pipe keeps pure water pure.

Lower bacterial growth:

Bacteria build up with CPVC is far lower than with alternative piping materials - Copper, Steel and other thermoplastics.

No Scale, pit or leach formation:

Even after years of use in the most aggressive conditions, SAGAR CPVC pipe won’t corrode, standing up to low pH water, coastal salt air exposures and corrosive soils. SAGAR CPVC Pipe stays as solid and reliable as the day it was installed. It maintains full water carrying Capacity because its scale resistance means no build up to cause water pressure loss.

Unaffected by chlorine in the water

Some materials may be adversely affected by chlorine contained in the water supply, which can cause breakdown of the polymer chains and potential leaks. In this respect, SAGAR CPVC pipe is unaffected by the chlorine present in potable water supply.

Low thermal expansion:

SAGAR CPVC pipe has a lower coefficient of thermal expansion than alternative plastics, reducing the amount that the pipe expands when hot water is running, again reducing unsightly ‘looping’ of the pipe.

Easy Plumbing process:

CPVC uses a simple, solvent cement jointing method. Tools required are very simple and inexpensive (chamfering tool and pipe cutter only) and avoid the need for an electrical source. Superior insulation : SAGAR CPVC pipe is more energy efficient than metal pipe. As an insulator it does not lose heat the way metal pipe do. Heat loss and thermal expansion are reduced. Superior insulation:

Hot water compatible:

SAGAR CPVC pipe is compatible with both hot and cold water. It withstand very high temperature compared to any other thermoplastic plumbing systems. Many solar and electric water heaters have CPVC piping system for heat efficiency and lower installation cost.

Tough, rigid material:

SAGAR CPVC pipe has a much higher strength than other thermoplastics used in plumbing. This means that CPVC needs less hangers and supports and there is no unsightly looping of the pipe. SAGAR CPVC pipe Has a higher pressure bearing capability. This leads to the same flow rate with a smaller pipe size.

Fire safety:

CPVC has a limiting Oxygen Index (LOI) of 60. Thus in air, SAGAR CPVC pipe does not support combustion. No flaming drips, does not increase the fire load, low flame spread, low smoke generation.

Approved world wide:

CPVC plumbing system is approved for contact with potable water in wide range of countries including USA, UK, Canada, Germany, France, The Netherlands, Middle East among others. Here in India, SAGAR CPVC plumbing system is approved by BMC and CPWD for potable water supply.

CPVC Pipes & Fittings Joining Instructions

Cutting

If necessary, cut the ends of pipe square. Cutting the pipe as squarely as possible provides the surface of the pipe with a maximum bonding area. If whole pipe is to be assembled, there is no need for cutting the pipe.

Bevelling/Deburring

Burrs can prevent contact between pipe and fitting during assembly. So use chamfering tool or file to remove the burrs from outside and inside surfaces of the pipe. For easy entry of the pipe into the socket and to minimize the chances of wiping PVC cement from the socket, a slight bevel of about 10º-15º shall be placed at the end of pipe.

Joining Preparation

Keep ready all the pipes and fittings which are to be joined, inspect them for any damage or irregularities. Check dry fit of pipe and fitting. Pipe should easily go 1/4 to 3/4 way in into the fitting.

PVC Cement Application

PVC cement is to be applied on clean surfaces and while primer is still tacky. It is to be applied with proper applicator on the O.D. of the pipe end, equal to the depth of the fitting socket. Coat of PVC cement should be even and heavy enough to fill any gap. If necessary, apply second coat. Apply medium coat to the fitting socket with a suitable applicator. Avoid pudding.

Assembly

Assemble the cemented parts quickly while cement is wet. If interrupted, recoat both parts. Push pipe fully into fitting by twisting 1/8 to 1/4 turn. To avoid pushout, hold the assembly for about 60 seconds. Excess cement should be wiped off by cloth. A continuous bead of solvent cement should be the evidence of properly joining of pipes & fittings.

Set & Cure Times
