ISOflanges' presentation at the 36th Oldenburger Rohrleitungsforum 2024 will focus on the new HTG insulating flange connection. Made from a material with high thermal resistance and excellent electrical insulating properties, the design fulfils KKS requirements and is characterised by high temperature resistance (HTB) in accordance with DIN EN 1775.
The HTB test was carried out at the DBI (Gastechnologisches Institut gGmbH Freiberg). The insulating flange connection was successfully tested in accordance with the test requirements - at 650 °C for 30 minutes - and its functionality was verified. This means that the HTG version is suitable for use in district heating pipes with a maximum operating temperature of 260 °C (superheated steam).
The HTB certificate is also relevant for insulating isolators that are used inside buildings where this certificate is required due to safety requirements. Standard insulating isolators are not sufficient here. They often only have a maximum operating temperature of up to 100 °C and therefore do not fulfil the HTB test requirements.
ISOflanges also presents high-performance insulating flange connections in the HP high-performance version, for example. These DVGW-certified components now also demonstrate their strengths in application scenarios with up to 100% hydrogen.
With the HP SW5 B and SW3 B versions, there are also solutions for the safe electrical (galvanic) isolation of steel pipes in "black-white connections" to protect against bimetal corrosion.
The new insulating flange design type HP RF5-KKS and type HP RTJ5-KKS offers a 100 % KKS solution even in confined installation conditions - such as the conversion of existing 5 mm "insulating gaskets".
