Presents a new method from British Gas on testing leaks in gas pipelines. Passage of pressured air into the pipe; Measurement of drift rate in differential pressure. Evaluation of failure risk due to use of high-strength HDPEs in pipelines.
GIS/PL2-8: Polyethylene pipes & fittings for transport of natural gas and suitable manufactured gas – Part 8: Pipes for use at pressures up to 7 bar Codes of Practice are generally specific to individual countries, industry sectors or utilities.
The performance of buried natural gas pipelines loed in areas prone to ground movement is a major concern for utility owners since the failures of such pipeline systems during service is extremely serious due to the potential for loss of life, as well as the associated environmental and economical impacts. With plastic pipes now the industry standard for most utility distribution systems (e Puhui Pipe manufacturer in China
Piping made from polyethylene is a cost effective solution for a broad range of piping problems in municipal, industrial, marine, mining, landfill, duct and agricultural appliions. It has been tested and proven effective for above ground, surface, buried, sliplined,
The gas ducting must be yellow and perforated. This allows the pipe work to be identified as gas and for the gas to vent safelyin the event of a leak. Gas ducting must be to British Standard BS4962 “Specifiion for plastic pipes and fittings for use as sub soil
ETI Polyethylene Line Pipes & Fittings are manufactured on state-of-the-art German and Austrian equipment to meet the performance requirement of British Gas Technical Specifiion for gaseous fuel. liions: • Distribution pipe for Natural Gas, Liquefied Petroleum Gas
Use of thermoplastics pipe systems for gas distribution Polyethylene (PE) and polyvinyl chloride (PVC) were discovered in the 1930s and the use of these materials for production of water pipe commenced after the war. In the 1960’s Du Pont developed a PE
The nascent metal pipes industry, with the industrial Midlands at its centre, created companies that were to develop, amalgamate and go on to produce polyethylene pressure pipe for water. It also ultimately led to the formation of the UK’s largest ever single organisation in this field, Glynwed Pipe Systems Ltd.

IGEM provide gas standards that cover safety regulations, knowledge, best practice and gas engineering requirements for the gas industry in the UK and overseas. Our suite of technical gas standards are trusted by gas professionals and highly regarded by organisations such as Ofgem, the Health and Safety Executive (HSE) and Gas Safe Register.
1/1/1991· Pipes, typically of medium density polyethylene for use in underground distribution systems for natural gas are joined by fusion using a very short period (25 seconds) for heating the pipe ends and a Method for joining polyolefin pipes by fusion - British Gas Corporation
Polyethylene Pipe Polyethylene pipes are used in a wide range of pipes for drainage, irrigation, water service and even some varieties for underground gas transport. It is durable and provides long-term resistance to environmental conditions in outdoor and underground uses.
Manufacturer of standard and custom polyethylene pipe for natural gas distribution. Offers low resistance to fluid flows. Products are lightweight and are chemical, abrasion and corrosion resistant. Protects against rain, snow, sleet, hail, dust, dirt, sand and debris.
Specifiion for polyethylene pipe and fittings for natural gas and suitable manufactured gas. Yellow PE4710 and Secura-Line pipes up to 630 mm Part 1 General and polyethylene compounds for use in polyethylene pipe and fittings Raw materials Self-certified
English:A polyethylene gas main being laid in a trench under Chesterton Road, Caridge. The bright yellow polyethylene (PE) pipes have been used to replace older ductile iron pipes since the 1970s. Once complete, the pipeline will operate at a pressure of 75 millibar since it
The pipe and fittings covered by this specifiion are intended for use in the transmission and distribution of natural gas. Requirements for the qualifying of polyethylene systems for use with liquefied petroleum gas are also covered. This specifiion does not
Canadian Western Natural Gas (CWNG), like most U.S. and Canadian gas distribution utilities, was slow to adopt electrofusion for joining polyethylene pipe, but after extensive evaluation the hdpe pipes has approved the fusion method for difficult tie-ins and repairs.
Gas mains in the united Kingdom fall into the following types: 1. Intermediate pressure mains operating between 2 and 7 bar and constructed from either HDPE or polyethylene pipe. 2.Medium pressure mains operating between 75ar and 2bar
