(IS:13592-1992)
CONSTRUCTION: Tijaria/Vikas SWR Pipes & fittings are manufactured by compounding uPVC resin along with chemicals such as heat stabilizers, processing aids, lubricants, benzotriazole, phosphite based U.V. stabilizers, pigments and carbon black UV stabilizers which noticeably improves the light stability of uPVC, prevents yellowing, imbritflement and loss of mechanical strength.
PRODUCT RANGE:
Selfit: These pipes have bell type socket at one and. Available in 40 to 160 mm sizes.
Ring-O-Socket: These Pipes have ring type socket at one and . Available in 40 mm to 160 mm sizes. |
|
| ADVANTAGES:
Easy installation: Due to light in weight these pipes are easy to install and less time consuming than cast iron or cement Pipes. High Chemical Resistance : Highly resistant to acid alkalies, cement, lime, Oils and domestic effluents. Free Flow: Due to it's smooth inside surface any liquid flows very. Durable: These are strong and durable because of weather and sunlight resistant. These are also unaffected by termite, bacteria and fungus.
