HDPE Pipes

Sterling Pipe Incorporation (SPI) is a well-known manufacturer in the industrial, municipal, agricultural/irrigation, domestic pipe markets.

Sterling Pipe Incorporation (SPI) is a well-known manufacturer in the industrial, municipal, agricultural/irrigation, domestic pipe markets. Engineered for gravity flow systems and also pumping mains a wide range of HDPE Pipe are available to meet specific requirements of customers. Proper raw materials with specified grades (PE63, PE80, and PE100) are selected for production and these polyethylene’s’ are polymerized in controlled environment thus producing PE pipes of high quality products, superiority on nature.
Polyethylene (PE100) pipes can carry potable water, waste water, slurries, chemicals, hazardous wastes and compressed gases. In fact, PE100 is strong, extremely tough and very durable when compared to it preceding material like PE 80 grade and PE63 grade. PE100 pipe has superior qualities in terms of mechanical and all also other properties when compared to PE80, PE63.
The Polyethylene material used for the manufacture of pipeline systems are classified and dimensioned by long term performance under hydrostatic pressure in accordance with IS-4984:1995. The design basis used in IS-4984:1995 for Pressure rating (PN rating) of PE pipes in order to determine the minimum wall thickness for each diameter and PN rating provides for the steady and continuous application of the maximum allowable working pressure over an arbitrary period of 50 years.
The selection of the long term hydrostatic design stress value (HDS) is dependent on the specific grade of PE and the pipe material service temperature.
