HDPE Pipes

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.

UV Resistance

HDPE Pipe contains a minimum of 2% carbon black additive to protect the product from ultraviolet light. This gives HDPE Pipe maximum weather resistance in applications where continuous exposure to the elements is expected.

Chemical Resistance

HDPE has the highest level of chemical resistance of all traditional sewer products. HDPE Pipe brings the gravity flow sewer market the same exceptional performance remaining tough and resistant under conditions that could seriously damage pipe made of other conventional materials.

Abrasion Resistance

Tests indicate that HDPE Pipe is highly resistant to abrasion, giving it a significant advantage over other pipe materials in both acidic and abrasive environments. Piping made from polyethylene is a cost effective solution for a broad range of piping problems in municipal, industrial, marine, mining, landfill, duct and agricultural applications. It has been tested and proven effective for above ground, surface, buried, slip lined, floating, and sub-surface marine applications.

Corrosive Resistance

Polyethylene is resistance to corrosive acids, bases and salts than most piping materials. In addition, polyethylene is unaffected by bacteria, fungi and the most “aggressive” naturally occurring soils. It has good resistance to many organic substances, such as solvents and fuels.
