HDPE pipe has been utilised in non-potable water applications for decades. HDPE pipes, in particular, are popular because of their welded connections. While welding requires special equipment to make the weld, it does away with the necessity for separate fittings, which are a common cause of leaks and contaminant infiltration.
HDPE is a very flexible polymer that can withstand more abuse on the job site than more brittle polymers like PVC. Turns in the piping system can also be made without the use of additional joints because to flexibility.
Because it is lightweight, corrosion resistant, quick to install, and has a low maintenance cost, high density polyethylene (HDPE) is utilised as a drainage pipe material. The premise behind the design of HDPE corrugated drainage pipe is that it will deform and so reduce stress. As a result, ductility is a critical property for allowing for permitted deflection during the pipe's service life. Due to a process known as "slow crack progression," HDPE resins with low ductility might cause unexpected cracking in the pipe. The stress crack resistance (SCR) of HDPE resins must be appropriately analysed to reduce such cracking.
HDPE pipes are non-corrosive and easy to deal with, making them more convenient and long-lasting. HDPE pipes are lightweight and use less energy in the production process. Other polyethylene’s, on the other hand, have different densities, hyper-branched crystallinities, and molecular weights and chain structures. In general, the processing temperature for HDPE is 160oC-250oC, with a shrinkage rate of 1.5 percent to 3%. HDPE is a major polymer in the production of a wide range of plastic items due to its high heat resistance, flexibility, and machinability.
The India HDPE Pipes Market was worth $99.9 million in 2018, and is predicted to grow at a CAGR of 11.2 percent from 2019 to 2026, reaching $233.5 million. Raw materials such as PE 63, PE 80, and PE 100 are used to make high density polyethylene (HDPE) pipes. HDPE pipes are 6-8 times lighter than cast iron and galvanised iron pipes, which is one of their major advantages. Because of its great chemical resistance, HDPE pipes may be easily shaped and welded together. Furthermore, they are non-corrosive, making them an excellent choice for a variety of applications.
