Oil and gas companies and mining companies seeking cost cutting measures might be considering high density polyethylene (HDPE) pipe being a money-saving option to HDPE pipe fittings. Reinforced thermoplastic pipe (RTP) offers some great benefits of corrosion resistance and light-weight weight and it is already used in moderate temperature and pressure applications.
The Plastic Pipe Institute web site explains several of the main reasons why plastic pipe meets the requirements of 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 also well suitable for the solids environment in mining applications.
PE pipe is semi-rigid to stand up to high external loads. Its flexible nature expands with pressure surges that raises the life 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 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 readily installed without heavy lifting equipment. Alternate installation methods (Horizontal Directional Drilling, Pipe Bursting, Sliplining, Plow and Plant, Submerged or Floating Pipe, etc.) can save considerable money and time in most applications.
PE pipe is manufactured in straight lengths approximately 50 feet long and coiled in diameters up through 6-inches. Coiled lengths over 1,000 feet can be purchased according to size.
PE and HDPE pipe has been utilized in the oil and gas exploration industry for years. As outlined by articles on Pipeline & Gas Journal, HDPE pipe is commonly used in fracking for the collection and transportation of hydrocarbons, plus the transportation and selection of water employed 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 around 3,000 psi and also in some of the 18dexkpky difficult terrains across the country. Plastic pipe can also be valued because of its flexibility; gas distribution systems are definitely more likely to survive severe ground shifts, especially from earthquakes, while they are created from fused PE pipe.
