Tanktec® PTFE Envelope Gaskets for bottom outlet arrangement
Tanktec® PTFE Envelope gaskets combine the chemical resistance and hygienic properties of virgin PTFE with the better mechanical properties of a Compressed Non-Asbestos Fibre (CNAF) filler. The PTFE Envelope is 0.5mm thick with a unique inner diameter profile. The filler is made from non-asbestos mineral and organic fibres with a NBR rubber binder.
Many years of experience in the fluid transportation industry and close cooperation with end-users have resulted in a comprehensive range of tailored PTFE Envelope gaskets for tank containers Tanktec® PTFE Envelope gaskets are available in specific flange dimensions as well as various Multi-fit sizes, designed to fit and seal various flanges and thereby eliminating the need for additional stock of gasket sizes. We offer both Inside Bolt Circle (IBC) or flat ring as well as Full Face (FF) gaskets with bolt holes for exact positioning on flanges.
The Tanktec® PTFE Envelope gaskets are machined from virgin PTFE and have a unique inner diameter profile:
The dimensions of the PTFE Envelopes are such that they cover the complete area with serrations on the flanges.
Service capabilities:
Pressure >10 Bar (145psi)
Temperature Max 250°C (482°F)
Media PTFE is inert to almost all chemicals, with the exception of some alkali metals (molten or in solution) and by some rare fluorinated compounds at high temperatures and pressures.
Coating Center can offer flange gaskets in a large variety of materials from filled or modified PTFE to elastomeric and graphite based materials.
