IDT-Profile FD 30
Designs

High-quality PTFE seal (Dyneon™TFM™) occluded by means of a special steel interior and exterior eyelets for use between flanges using a groove and tongue.
Thickness of the eyelet steel 0.15㎜
Eyelet formed without seams up to DN 300 on the interior DN 200 on the exterior. The butt-welding process which is especially used guarantees corrosion resistant double eyelet butt joint seams.

Characteristics
No running of the seal when subjected to surface pressure
Very low construction (from 1.5㎜ thickness)
Very good gas impermeability (<0.01mg/s·m)
Easy removal of the seal from the groove when removing the flanged connection
No soiling of the product (FDA-conform)
High-quality seal as defined in German "TA-Luft" (limits for emissions)

Areas of Use

Between flanges with a groove and tongue
Against corrosive media (flange materials selectable according to the operational media)
Alternative design to grooved profiles and spiral seals for low flanged groove depths
  (max. DN 80 is the groove depths 2.5㎜)


 
IDT-Profile WD 60

 

Designs

High-quality PTFE/Steel compound seal with 5㎜ wide diffusion stop and optimised special steel corrugated ring inserts. The compound components are so matched to each other that these results in excellent characters with regard to the sealing technology. The Dyneon™TFM™ 1600 which is used as a much lower deformation rate when subjected to pressing than conventional PTFE, even when subjected to high temperatures whilst the structure which has a low number of pores reduces the gas permeability.

The special steel corrugated ring occludes the PTFE, resulting in a high level of blow-out certainty and reduces the diffusion cross section of the seal.

The diffusion stop which is positioned in the interior diameter minimises the leakage rate further and protects the corrugated ring against corrosion resulting from the media.

Areas of Use

The main areas of use are there where a high level of safety standards are required when sealing highly corrosive, hazardous and toxic media, with the realisations of relatively low surface pressures, as well as such sensitive areas as the lacquer, paints, pharmaceutical and food industries. The vacuum is reliably controlled.

The users are provided with detailed assembly instructions and if they should so require, calculations concerning the design of the sealing connections

Characteristics

High-quality seals defined the German "TA-Luff" (limits for emissions), excellent gas and liquid
  sealing properties with a relatively low surface pressures
Resistant to almost all chemicals and solvents
No subsequent tensioning required
Blow-out certainty
No special demands placed on the raised and flat faces; flange form C is sufficient
