Oil and gas companies and mining companies seeking cost cutting measures might be considering high density polyethylene (HDPE) pipe being a money-saving substitute for PEX-AL-PEX pipe. Reinforced thermoplastic pipe (RTP) offers the benefits of corrosion resistance and light weight which is already used in moderate temperature and pressure applications.

The Plastic Pipe Institute web site explains several of the reasons why plastic pipe meets the requirements from the mining industry:

Polyethylene (PE) pipe is rustproof, break-resistant and corrosion-free.

PE pipe can withstand harsh chemical environments.

PE pipe is abrasion resistant and is well designed for the solids environment in mining applications.

PE pipe is semi-rigid to resist high external loads. Its flexible nature expands with pressure surges that improves the life of the pipeline.

PE pipe installations have long-term cost advantages because of its physical properties, leak-free joints and reduced maintenance costs.

The service life for HDPE pipe fittings is definitely an estimated 50-100 years.

The “allowable water leakage” is zero instead of typical the leakage rates of 10% to 20% for PVC and Ductile Iron.

Lightweight PE is definitely installed without heavy lifting equipment. Alternate installation methods (Horizontal Directional Drilling, Pipe Bursting, Sliplining, Plow and Plant, Submerged or Floating Pipe, etc.) could save considerable money and time in the majority of applications.

PE pipe is produced in straight lengths as much as 50 feet long and coiled in diameters up through 6-inches. Coiled lengths over 1,000 feet are offered depending on size.

PE and HDPE pipe has been utilized within the oil and gas exploration industry for a long time. As outlined by a post on Pipeline & Gas Journal, HDPE pipe is utilized in fracking for the collection and transportation of hydrocarbons, and also the transportation and variety of water used in this technique. Composite pipe comprising layers of HDPE and metallic and non-metallic (glass and carbon fiber) substrates has been used for pressures from 300 psi up to 3,000 psi and in a few of the 18dexkpky difficult terrains country wide. Plastic pipe is additionally valued for the flexibility; gas distribution systems are more apt to survive severe ground shifts, especially from earthquakes, when they are made from fused PE pipe.
