Gas is the most popular fuel line in domestic plumbing. Plumbers are responsible for gas line installation necessary for the household heating and cooking. Natural gas is carried at low pressure to your home via underground street pipes while propane gas is delivered from storage tanks located behind buildings or buried underground.
The fuel gas codes require that piping beyond specified lengths be purged with an inert gas based upon the nominal pipe size. one of two methods: (a) fuel gas is used to directly displace the air, or (b) inert gas is used to displace the air and then fuel gas is used to displace the inert gas.nsure personnel involved in gas purging operations are fully trained and knowledgeable about safe gas venting practices, the proper use of gas detectors, and the danger of relying on the sense of smell alone to detect gas releases. Include training on the problem of odor fade in new gas piping systems.
