tanya jawab: Seputar HDPE


 What fittings are available for HDPE pipe?

HDPE fittings in standard configurations, including straight and reducing tees, elbows, crosses, Concentric and eccentric reducers, flanges, mechanical joint adaptors, outlet branch-saddles, etc. These can be fused directly to the HDPE pipe. Custom fittings are also available upon request.


In what lengths is HDPE pipe available?

It is available either in coils or straight lengths. Coils are normally  available for small diameter pipe ( 6 inch and smaller). For diameters 3 inch and larger pipe is normally available in straight lengths up to 50' in length.

Is the pipe available in both ductile iron pipe size and iron pipe size outside diameters?

Yes, HDPE pipe is available both in iron pipe (lPS) and ductile iron pipe sizes (DIPS), Sometimes also known as cast-iron pipe sizes (CIPS). Ductile iron pipe sizes are available in 3 Inch to 54-inch diameters. Iron pipe sizes are available from 3/4 inch to 63-inch diameters.

How long has HDPE been used in sewer and water applications?

Polyethylene has been used for sewer force mains, gravity flow sewers, and  pressure water Main applications for approximately 50 years. After many years of field proven performance, it became a standardized material and product. The first American Water Works Association (AWWA) Standard for HDPE Pipe, C901, HDPE Pipe and Tubing inch through 3 inch was adopted in 1978. AWWA Standard for larger pipe, C906, HDPE Pipe and Fittings, 4 inch through 63 inch, was adopted in 1990.

What is the life expectancy of HDPE pipe?

The US EPA expects 1O0-year service life from HDPE land fill liners. Buried  solid wall or profile wall HDPE pipe should last at least as long .HDPE pressure pipe was first used in water service over 50 years ago. Current accelerated testing methods predict that today's HDPE pressure pipes will last much longer than 50 years. Everything points to a service life of at least 100 years in a properly designed and installed HDPE pipe system.
