Gas Reticulation Project
There are two types of fuel gases that are normally piped or reticulated to end-users which are liquefied petroleum gas (LPG) and natural gas. Due to its very low boiling point, natural gas is transported in pressurised vapour state from gas processing plants or terminals via pipelines to end-user appliances. There is no natural gas storage at the consumer’s premises. LPG, due to its relatively higher boiling point, is transported by road tankers in the liquid state from refineries or terminals and stored at consumer’s premises in storage vessels before it is vaporised and piped to end-user appliances. Hence, in LPG systems there is a risk of liquid being leaked or released from the system. Small volume of liquid LPG leaks from the storage system will expand to become an enormous volume of flammable vapour/air mixture, which may give rise to BLEVE (boiling liquid expanding vapour explosion). Since there is no natural gas liquid at the consumer’s premises, similar leakage of natural gas will give rise to a much smaller volume of flammable vapor and air mixture. Therefore, the purpose of this project is to study the piping installation and distribution in the real application. Comply of MS 930 and MS 830 standards during pipe system installation, performing leak test, pressure test and purging process as stated in Code of Practices and Safety should be taken would be cover in this project.
