24/5/2007· I know the use of HDPE pipe is becoming more and more common for water mains, but I also believe it is fairly new in this type of use, so truly understanding it''s life span seems to be an issue. From the little research I''ve done, it seems that the most important part of construction that ensures a longer life-span is correctly welding the joints together.
24/10/· I would also say that not all cast iron and HDPE is created equal. For cast iron, an outer anti-corrosion layer is essential. Some manufacturers use a zinc/aluminum alloy on the pipe while others use zinc and aluminum but not an alloy, which is a game changer.
When galvanized iron suffers the same fate, it’s best to replace it since damage can also erode the zinc layer, which makes it rust-free. In turn, it may be more expensive to work with galvanized HDPE pipe than an HDPE in the long run. PVC vs. HDPE

In the constant battle between ductile iron and PVC, simple truths are sometimes forgotten in the fog of war. We would like to take a moment to remind all of the following: PVC Pipe [Fittings]: Unsurpassed Longevity and Sustainability PVC pipe [fittings’] life
2 DUCTILE-IRON PIPE AND FITTINGS had been achieved in producing lower-cost iron by using coke instead of charcoal. Fol-lowing this success, the more progressive cities began to install cast-iron mains. The use of cast-iron pipe was introduced in the United
* HDPE pipe can be heat fused together to form a joint that is as strong or stronger than the pipe itself and is leak free. o o This eliminates the potential leak points every 10-20 feet as found with PVC and Ductile Iron bell and spigot connections. * The Life Cycle
Whereas Ductile Iron pipe standards have always been conservatively consistent for all sizes, the C905 and C900-07 standards for pvc pipe differ substantially from the C900-97 standard. C905 and C900-07, for example, provide for a thinner wall, greatly reduced Puhui Pipe manufacturer in China

in support of this study indied that ductile iron was used, rather than plastics. In total, the Cities collectively installed approximately 1% to 3% of all pipe as plastic during 2013 to 2015, in comparison to 97% to 99% ductile iron. Materials data were not
Ductile iron pipes are beneficial when used in certain soil types and ground conditions. These pipes are particularly useful in areas of high pressure, where the surface pressure can transfer to the pipe and cause damage or deformations in the pipe materials.
Puhui HDPE pipeline’s HDPE pipe for water and sewer is manufactured for excellent performance and a long life expectancy. Its butt-fused joints eliminate potential leak points, common at 10 to 20 feet with ductile iron pipe, for a zero leak rate. Highly resistant to corrosion and
Considering the relative difference in pipe wall thicknesses, DI pipe has the largest inside diameters (where the flow happens) amongst Ductile iron, HDPE and PVC pipes. Using 12-inch pipe as an example, the present worth of excess energy costs to pump the same volume of water through each mile of HDPE pipe (versus 12-inch DIP) in just the first 25 years of operation computes to well over Puhui Pipe manufacturer in China

Repairs to ductile iron pipe are generally much easier to complete. When issues occur, they are typically point source repairs that can easily be remedied with the installation of a stainless HDPE repair clamp or a spool piece of pipe and a couple of restrained Mechanical Joint sleeves. sleeves.
