17 Introduction controlled area requiring certified pipes of the highest quality and traceability of both product and raw material. Our gas pipes are used for the transportation of e.g. natural gas and biomethane. Extena was quick off the mark to develop systems for maximum control and traceability and today offers Inspection certificate 3.1 according to EN 10204 for customers who require it. Our traceability makes it easy to trace e.g. suppliers of raw materials, pipes and pipe fittings, including the extrusion line and date of manufacture. The aim is to ensure that our customers are confident in their choice and know that their gas pipelines are of the highest quality. We offer pipes for gas pipelines installed in trenches (standard pipe 90/10) as well as for alternative installation methods (SLM®). Our range of gas pipes also includes the unique multilayer pipe HexelOne®, which can withstand a gas pressure of 16 bar. We can also offer pipes and pipe fittings from the same batch and with 3.1 certificates. • Gas can be fatal • Gas pipelines with maximum control • High traceability • EN 10204 Inspection certificate 3.1 • EN 1555 • Option to order pipes and pipe fittings from the same batch The manufacture of gas pipes is defined in various standards and directives such as EN 1555. SS-EN 10204 is a European standard that regulates the design of Inspection certificate 3.1. We can supply pipes with Inspection certificate 3.1 according to EN 10204 for customers who require it. Swedish Gas Association and EGN 2020 Extena is a member of the Swedish Gas Association (Energigas Sverige), an organization for stakeholders in the energy gas industry. Members of the association include grid operators, gas suppliers, manufacturers and suppliers of gas equipment, installation companies, consulting companies, etc. Grid operators that are members of the Swedish Gas Association have undertaken to comply with these standards. A central part of the association’s activities is to promote the safe use of energy gases (natural gas, biogas, LPG, vehicle gas and hydrogen). This involves drawing up standards and instructions. The regulations up to 4 bar for natural gas, biogas and LPG in the gas phase are coordinated in EGN 2020. The construction, inspection and operation of distribution systems for gas, natural gas, biogas and LPG in the gas phase as well as associated installations according to EGN ensure compliance with the reasonable precautions clauses of the legislation on flammable and explosive materials. Industry Plastic pipes have many applications in industry, which means that requirements vary significantly. Extena offers probably the widest range of high quality pipes and pipe fittings on the market, including various special pipes adapted for special functions and conditions. We offer pipes for every demand – for high pressures and temperatures as well as large flows, abrasive media and heavy external loads. Plastic pipe systems have many advantages, including the fact that they are corrosion resistant and that they are highly resistant to a large number of chemicals and aggressive media. Plastic pipe systems also provide high operational reliability because they are both robust and flexible. Combining polyethylene pipes with another type of plastic or metallic material such as aluminium creates new functions and application options. Permeation tightness, high pressure resistance and extra durability for transporting heavy media are just some of the functions that can be achieved with these material combinations.
