Open all Close all Technical data Note Information for ordering
- technical delivery conditions according to EN 10305-1 and EN 10305-4, steel type E235+N (normal annealed in delivery condition), material number: 1.0308
- dimensions and tolerances according to EN 10305-1 and EN 10305-4
- surface design: galvanised coat according to EN 50961, layer thickness 8 up to 12 μm and with Cr-6-free passivation
- minimum and maximum temperature TS: 0 °C to +300 °C
- If an inspection certificate 3.1 pursuant to EN 10204 is required, please indicate this separately when placing your order.
- The surcharge for wear and tear c0 in the event of corrosion according to AD 2000 instruction sheet B0, also known as the corrosion surcharge c pursuant to EN 13480-3, amounts to c0 = 1 mm for ferritic steels.
It does not apply if the steel is sufficiently protected against the influences of the operating medium. On the other hand, in the event that a heavily corroding operating medium is used, a higher surcharge for wear and tear must be agreed. - The maximum permissible pressure PS (at +20 °C) according to EN 13480-3 is specified in the table of products as case 1 and case 2:
- case 1 (c0 = 0 mm) e.g. for LPG
- case 2 (c0 = 1 mm) e.g. for fuel oil, water
- The indicated transportation length results from a 5 m rod that is shortened for transportation!
No liability assumed for the specifications for maximum permitted pressure!
Product note For the correct selection and assembly of compression fittings, please refer to the GOK assembly manual and the data sheets for compression fittings and screw-in connectors (at www.gok.de/en/data-sheets or www.gok.de/en/installation-instructions). If you are installing a compression fitting with copper or aluminium pipe, you must use a reinforcement ring. For aluminium pipes, use a reinforcement ring made of steel! All compression fittings are approved by the DVGW.
