Oil and gas companies and mining companies seeking cost cutting measures can be considering high density polyethylene (HDPE) pipe as being a money-saving substitute for PEX-AL-PEX pipe. Reinforced thermoplastic pipe (RTP) offers the advantages of corrosion resistance and light weight and it is already being used in moderate temperature and pressure applications.
The Plastic Pipe Institute web site explains a few 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 which is well suitable 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 lifetime of the pipeline.
PE pipe installations have long lasting cost advantages due to the physical properties, leak-free joints and reduced maintenance costs.
The service life for HDPE pipe fittings is undoubtedly an estimated 50-100 years.
The “allowable water leakage” is zero as opposed to 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.) will save considerable time and expense generally in most applications.
PE pipe is made in straight lengths as much as 50 feet long and coiled in diameters up through 6-inches. Coiled lengths over 1,000 feet are available dependant upon size.
PE and HDPE pipe has been used from the oil and gas exploration industry for years. Based on articles on Pipeline & Gas Journal, HDPE pipe is commonly used in fracking for that collection and transportation of hydrocarbons, plus the transportation and variety of water found in this process. Composite pipe made up of layers of HDPE and metallic and non-metallic (glass and carbon fiber) substrates has been used for pressures from 300 psi as much as 3,000 psi as well as in several of the 18dexkpky difficult terrains throughout the country. Plastic pipe is likewise valued for the flexibility; gas distribution systems will be more apt to survive severe ground shifts, especially from earthquakes, when they are produced from fused PE pipe.
