operating media:
diesel, LPG, fuel oil, fuel oil bio, industrial oil, petrol, inflammable gases and liquids of category 1 to 3 and non-flammable gases and liquids as well as water-endangering liquids
The seamless precision steel pipe meets the requirements:
- of AD 2000 instruction sheets HP 100 R and W 4
- of worksheet DWA-A 791
- pursuant to EN 10305-4 / ISO 10763 for connecting compression fittings pursuant to EN ISO 8434-1
- of MVV TB
- 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!
