|
Standard type of steel in accordance with the technical
specification for tube connections according to DIN 3859. The nuts are cold- or
hot-pressed respectively.
|
|
| Surface protection | |
|
Standard design steel, phosphatized, oiled, Znph r 5f in accordance with DIN 50942. Other surfaces available:
To be specified separately, when ordering. AVIT welding cones and welding parts are oil protected.
|
|
| Standardization | |
|
As far as applicable, AVIT welding couplings are identical with the dimensions of DIN 2353/ EN - ISO 8434-1. In case of standardized connections the respective DIN/EN ISO-number has been indicated. Technical specifications in accordance with DIN 3859 are adhered to, as far as applicable.
|
|
| Pressure range | |
|
AVIT couplings
reach higher values than indicated in the respective DIN- and ISO-tables.
The tables for the pressure selection as shown on pages 1.08 -1.09,
include nominal and bursting pressure values. The calculation is based on
DIN 2413/III for dynamical loads. The use of couplings for higher pressures than indicated in the above-mentioned tables, is permissible on the condition that the safety factor is reduced accordingly.
