Of all the plastic materials available for piping systems PVC has been found to all possess the best combination of properties and economy. Poly Vinyl Chloride (PVC) is a thermoplastic used and approved worldwide as a dependable engineering material. PVC pipes are produced by mixing PVC resin (a petro-chemical product) with stabilizers, lubricants, pigments, fillers, processing aids and plasticizers
‘Hari Plaast‘ PVC PIPES & FITTINGS are manufactured conforming to various Indian & International standards like IS : 4985 , IS : 12818, ASTM- D- 1785, BS, DIN and ISO in various sizes ranging upto 315 mm in diameter in all classes and pressure rating.
It produces PVC pipes for every conceivable applications from drinking water supply and bore well systems to transportation of abrasive slurries.

These pipes are manufactured as per BIS 12818-1992 and supplied in 2, 3 & 4 meters length with one end having male threads & the other end having female threads. Threads are V or trapezoids type and protection caps are provided on the threads to protect the threads in transit. Two types of pipes i.e. Shallow Well (C.S.) and Medium Well (C.M.) are available.
Hari Plaast PVC Ribbed Screen pipes have longitudinal ribs and transverse slots. These pipes are generally used in combined wells where normal Screen pipes does not work. These pipes carries BIS Certification mark and manufactured in lengths 1, 2, & 3 meters with one end having male threads and the other end having female threads. The slot width range for screens is 0.2mm,0.3mm,0.5mm,0.75mm,1.0mm,2.0mm & 3.0mm.
These pipes are manufactured as per ASTM D 1785 and supplied in 3, 5 & 6 meters length with one end having male threads & the other end having female threads. These pipes are well accepted by the users everywhere for plumbing, water distribution and particularly in deep tube well connection because of higher collapse strength.
