Oil and gas companies and mining companies seeking cost cutting measures may be considering high density polyethylene (HDPE) pipe as a money-saving replacement for PEX-AL-PEX pipe. Reinforced thermoplastic pipe (RTP) offers the main advantages of corrosion resistance and light-weight weight and is already being used in moderate temperature and pressure applications.
The Plastic Pipe Institute web site explains a few of the explanations 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 best for the solids environment in mining applications.
PE pipe is semi-rigid to withstand high external loads. Its flexible nature expands with pressure surges that increases the lifetime of the pipeline.
PE pipe installations have long term cost advantages due to its physical properties, leak-free joints and reduced maintenance costs.
The service life for HDPE pipe fittings is definitely an estimated 50-a hundred 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 time and expense generally in most applications.
PE pipe is created in straight lengths as much as 50 feet long and coiled in diameters up through 6-inches. Coiled lengths over one thousand feet can be found dependant upon size.
PE and HDPE pipe has been utilized inside the oil and gas exploration industry for several years. Based on a post on Pipeline & Gas Journal, HDPE pipe is commonly used in fracking for your collection and transportation of hydrocarbons, and also the transportation and collection of water found in this technique. Composite pipe composed of layers of HDPE and metallic and non-metallic (glass and carbon fiber) substrates is being utilized for pressures from 300 psi approximately 3,000 psi and in some of the 18dexkpky difficult terrains throughout the country. Plastic pipe can also be valued for the flexibility; gas distribution systems are definitely more likely to survive severe ground shifts, especially from earthquakes, if they are made out of fused PE pipe.
