Have Smooth internal surface.Also these pipes are rust proof.corrosion free and do not
allow any deposit formation which implies better flow.
uPVC Plumbing Pipes (as per ASTM D 1785)
Strong and Durable
"Tirupati" uPVC Plumbing Pipes are strong and breakage free
Have Smooth internal surface.Also these pipes are rust proof.corrosion free and do not allow any deposit formation which implies better flow.
Are Fire resistant and have good electric insulation.
Have smooth internal surface which implies low frictional loss hence the power consumption is on lower side.
Long Lasting and Maintenance free:
Are free from breakage and environmental stress,which make it a life time investment.
Are very economical as reasonably priced,long lasting and maintenance free.
Installation Method :
Concealed Installation :
Under ground Installation :
Dimension of Unplasticized Pvc Pipes ( as per is 4985-2000)
|Nominal Outside Diameter. (m)||Mean Outside Diameter||Wall Thickness (mm)|
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.
