APPLICATIONS

  • Developed for seal­ing of the expan­sion joint 
  • Also suit­able for use in slid­ing ring seals if a sep­ar­ate seal is fit­ted for each pres­sure direction

CHARACTERISTICS

  • Radi­al adapt­ab­il­ity com­pensates for off­set and misalignment
  • Small base cross-sec­tions cause only slight com­pon­ent stress
  • Easy to handle due to robust construction 
  • For ret­ro­fits the seals can be adap­ted to the exist­ing install­a­tion dimensions 
  • Avail­able in any diameter

TEMPERATURE RANGE

From -20 to +100 °C

but depend­ent on the seal­ing ring mater­i­al in each case.

MATERIALS

IDG stand­ard seal­ing ring material

  • U95

Pen­stocks are used to dis­charge the head­wa­ter from a reser­voir. Due to thermal and dynam­ic effects on the pipelines which are usu­ally run under­ground in the moun­tain, com­pens­a­tion for expan­sion is necessary.

By fit­ting an expan­sion joint, slow creep move­ments, eccent­ri­city, dila­tion and also pipe mis­align­ment can be reli­ably absorbed.

The MANOY® sys­tem seal WP, type 436, was spe­cially developed for leak­age-free oper­a­tion of an expan­sion joint.
