SWR Pipes & Fittings
Airwin SWR pipes and fittings are specially designed and manufactured using high grade raw material and are an ideal solution for efficient removal of waste in the drainage system.
SWR pipes and fittings are used for non-pressure plumbing applications, such as transportation of soil, waste and rainwater, non-pressure industrial drainage applications, and waste discharge systems in residential and commercial complexes, resorts, and hospitals.
Airwin PVC SWR pipes system is an ideal replacement for CI and GI piping systems because it is lightweight, economical, non-corrosive and UV stabilised, which makes it highly durable. It offers extreme climate resistance and a smooth inner surface to prevent clogging.
Our stringent quality assurance approach across all stages of manufacturing gives the product a high-degree of reliability making Airwin PVC SWR pipes a preferred choice of leading MEP consultants, architects, builders, plumbing contractors, plumbers, and quality-conscious people across the country.
SWR pipes are available in various sizes ranging from 40 mm to 160 mm. These pipes are manufactured as per IS 13592 and are offered with Integrated Ringfit and Selfit socket systems.
SWR pipes are offered in two primary types; type A for rainwater and vents, and type B for soil and waste discharge. Fittings are available in various sizes from 40 mm to 160 mm in Selfit and integrated ring type sockets. Fittings are manufactured as per IS 14735.
SWR SELFIT PIPES
Conforming to IS 13592
Airwin Selfit SWR pipes are manufactured in a way that one end of the pipe is plain, while the other
is self-socketed and facilitates ease in jointing by the use of Airwin Solvent Cement.
SWR SELFIT FITTINGS
Fittings are available in various sizes from 40 mm to 160 mm in selfit sockets.
SWR PIPES WITH INTEGRATED RINGS
Airwin SWR pipes and fittings support easy installation as the Integrated Ring pre-fitted in the groove of the socket remains permanently positioned. The joint is made simply by pushing the spigot end into the socket end, without the use of any Solvent Cement. Airwin lubricant should be used for easy insertion. The ring forms a leak proof joint and absorbs the linear expansion and contraction, keeping the seal intact.
SWR FITTINGS WITH INTEGRATED RINGS
SWR pipe and Fittings are available in various sizes from 75 mm to 160 mm in integrated ring type sockets.

Technical Details
JOINTING
• For Selfit Pipes & Fittings:
1. Measuring : Measure the required length of pipe and marking done.
2. Cutting : The pipe must be cut in a square shape. The base of the fitting socket needs a rubber ring to seal it, since an angled cut may result in leakage.
3. Deburring & Chamfering : All the burr must be removed from the inside and outside of the pipe with a knife, file or de-burring tool. A 10° – 15° chamfer must be made at the end of the pipe.
4. Cleaning : The surface dirt, grease or moisture must be removed with a clean dry cloth.
| 5. Check Dry Fit : Using light pressure, the pipe should be inserted one third to half the way into the socket. Note that pipes and fittings that are too tight or too loose should not be used. |
6. Solvent Cement Application : An even layer of cement should be applied to the outer side of the pipe and a medium layer of the plumbing solvent cement to the inside of a fitting.
7. Assembly : Join the pipe and fitting socket till in contact with the socket bottom. Hold the pipe and fitting together until the pipe does not retract. The excess cement can be removed from the exterior surface of the pipe and fitting. A properly made joint will show a continuous bead of cement around the perimeter of the pipe and fitting.
For Pipes & Fittings with Integrated Rings:
1. Measuring : Measure the required length of pipe and marking done.
2. Cutting : The pipe must be cut in a square shape. The base of the fitting socket needs a rubber ring to seal it, since an angled cut may result in leakage.

Additional Information
THERMAL EXPANSION
SWR pipes and fittings are not concealed and are always exposed to external surfaces and sunlight. The diurnal
temperature varies at many places between 5°C to 20°C, which naturally leads to expansion & contraction of
pipes. This thermal expansion is required to be taken into consideration in the design of a sanitation system.
The expansion & contraction occurs more in vertical lines. Therefore SWR pipes with integrated rings are most
suitable for a vertical stack. It is necessary to maintain an expansion gap at rubber ring joints to allow movement
of pipe due to thermal expansion.
Please measure the socket length by a measuring tape and mark along the pipe. During installation, push the
pipe firmly into the socket fitted with an integrated ring till the gap between the mark on the spigot and
socket is about 10mm, to allow for thermal expansion. Airwin recommends selfit jointing for all horizontal
wastewater lines. Selfit fittings makes the system cost effective, without affecting the performance. Horizontal
pipes require closer support compared to vertical pipes. Pipe brackets/pipe clips must be used to anchor
expansion joints.
