| SAE high pressure flange |
| |
HANSA-FLEX approves flanges according to the following standards:
- standard for SAE flange: SAE J 518 C, ISO 6162
- standard for CETOP flange: CETOP RP 63H
- standard for square flange: ISO/DIS 6164
|
| All flange connections are bright steel standard versions with corrosion protection.
The utilised materials for the different flange connection types are listed in the
catalogue for each product group. Optionally and in the manufacturers discretion
different materials can partly be used. The flange connections can be delivered
optionally with complete mountings (set of bolts and sealing ring).
|
| |
| All pressure indications require a temperature application between -20° C and + 90° C.
Outside this temperature range the physical properties of the material are affected leading to a
decrease of the operating pressure.
|
| |
| Please note the pressure indication before initial operation. Maximum working pressure refer
exclusively to the flange connections. For any other components such as the implemented tubes
and hoses, the fittings and couplings etc. the respective pressure indications of the
manufacturers have to be taken into account.
|
| |
All HANSA-FLEX flange connections seal with a round type sealing form. The sealings
delivered from HANSA-FLEX are alternatively also available in NBR (=acrylonitrile butadiene
rubber) hardness 90 shore (standard) or Viton hardness 85- 90 shore (by request). For the
installation of the flanges we recommend the following tube types:
- precision steel tubes according to DIN 2391, grade C
- bright annealed (NBK) and seamless bright-drawn material: ST 37-4 or ST 52-4
- seamless boiler tubes according to DIN 2441, 1 and 2 of St 37-4 and St 52-4
- tubes according to ASA B36-10
