Selfit uPVC Pipe ( as per IS 4985-2000 )
   

Range:

Selfit pipes are manufactured in the range of 32mm to 400 mm diameters in 2,5,4.6,8 AND 12.5 KGF/cm2 Working Pressure.

 

Advantages:

• The pipes are odorless and hygienic for carrying drinking wter.

• Due to the smooth inside finish these pipes gives better flow characteristic in comparison to other metal pipes CI,GI or AC Pipes.

• These pipes are resitant to corrosion from chemical or galvanic action

• These Pipes are long lasting and maintenance free

• Selfit pipes offer fast installation and cost reduction due to less use of solvent cement.

Note1- The table is based on metric series of pipe dimension given in ISO 161/1 in respect of pipe dimensions and ISO DIS 4422.

Note2- The wall thickness of Pipe is based on safe working stress of 8.6 Mpa at 27°C.The working pressure gets reduced at sustained higher tempreatures.Occasional Rise in tempreature ,as in summer, with concurrent corresponding reduction in tempreature during rights has no deterious effect on the working pressure of pipes considering the total life of pipe.
