What is BS EN 1555‑2 about?
BS EN 1555‑2 is the second part of the series of documents specifies the characteristics of pipes made from polyethylene (PE) for piping systems in the field of the supply of gaseous fuels. BS EN 1555-2 also specifies the test parameters for the test methods. BS EN 1555‑2 covers a range of maximum operating pressures and gives requirements concerning colours.
BS EN 1555‑2 covers three types of pipes:
- PE pipes (outside diameter dn) including any identification stripes
- PE pipes with co-extruded layers on either or both the outside and/or inside of the pipe (total outside diameter dn) as specified in Annex A, where all layers have the same MRS rating. A coextruded pipe made of a combination of PE 100 and PE 100-RC layers shall be regarded as PE 100 and marked accordingly
- PE pipes (outside diameter dn) with a peelable, contiguous thermoplastics additional layer on the outside of the pipe (‘coated pipe’) as specified in Annex B
NOTE-In conjunction with parts 1 and 3 to 5, BS EN 1555‑2 is applicable to PE pipes, their joints, and to joints with components of PE and other materials intended to be used under the following conditions:
- A maximum operating pressure, MOP, up to and including 10 bar1at a reference temperature of 20 °C for design purposes
- An operating temperature between −20 °C and 40 °C
Who is BS EN 1555‑2 for?
BS EN 1555‑2 on supply of gaseous fuel through PE is applicable to:
- PE manufacturers and quality testing personnel
- Industries dealing with gaseous fuels such as mining, oil, and gas
- PE pipe specifiers and installers
Why should you use BS EN 1555‑2?
Plastic pipe systems made from PE have a lower risk of cracking and leakage compared to alternative materials as they cope well with external stresses. Their flexibility characteristics allow plastic pipes often to be changed around angles and obstructions without requiring extra joints and fittings. These features of the plastic pipe will help you build a safe and efficient piping system when it comes to supply of gaseous fuels. BS EN 1555‑2 lists a specific plastic pipe called polyethylene (PE) pipe used for the supply so gaseous fuel which is beneficial for the mining, oil, and gas industries because it is rustproof, break-resistant, and corrosion-free pipes which are useful in the industries to supply the gases through this pipe.
BS EN 1555‑2 specifies the material requirements for the piping system and its components which is helps industries dealing with chemical gases, enabling them to withstand harsh chemical environment.
The service-life of PE pipes is an estimated 50-100 years. PE pipes are also lightweight which can easily be installed without heavy lifting equipment. All these benefits will be helpful for you to reduce the cost of production expenses as it not only economical but also durable.
Today, apart from its wide use in the oil and gas production industry, PE is also the material of choice for leak-free method of transporting natural gas to homes and industries. As the buyer of BS EN 1555-2, your business can be assured of best industry practice that will help build customer reliability and confidence and ease safety concerns.
What’s changed since the last update?
BS EN 1555‑2:2021 supersedes EN 1555-2:2010. BS EN 1555‑2:2021 includes some technical changes with respect to EN 1555-2:2010. These include:
- PE 100-RC type materials with enhanced resistance to slow crack growth have been added
- Test methods have been updated
- New test methods have been added for PE 100-RC materials
