Oil and gas companies and mining companies seeking cost cutting measures may be considering high density polyethylene (HDPE) pipe being a money-saving option to HDPE pipe fittings. Reinforced thermoplastic pipe (RTP) offers the advantages of corrosion resistance and lightweight weight and is also already getting used in moderate temperature and pressure applications.
The Plastic Pipe Institute site explains some of the main reasons why plastic pipe meets the requirements of your 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 it is well suitable 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 improves the lifetime 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 undoubtedly an estimated 50-100 years.
The “allowable water leakage” is zero as an alternative to typical the leakage rates of 10% to 20% for PVC and Ductile Iron.
Lightweight PE is easily installed without heavy lifting equipment. Alternate installation methods (Horizontal Directional Drilling, Pipe Bursting, Sliplining, Plow and Plant, Submerged or Floating Pipe, etc.) can help to save considerable time and money in many 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 can be found based on size.
PE and HDPE pipe has been utilized inside the oil and gas exploration industry for several years. In accordance with an article on Pipeline & Gas Journal, HDPE pipe is utilized in fracking for that collection and transportation of hydrocarbons, as well as the transportation and variety of water used in this procedure. Composite pipe composed of layers of HDPE and metallic and non-metallic (glass and carbon fiber) substrates is now being utilized for pressures from 300 psi approximately 3,000 psi and also in some of the 18dexkpky difficult terrains country wide. Plastic pipe is also valued for its flexibility; gas distribution systems will be more apt to survive severe ground shifts, especially from earthquakes, when they are made from fused PE pipe.
