Pipework Elements For Oil And Water Circuits Image Text

Pipework Elements for Oil and Water Circuits

Close-coupled and temperature-resistant media supply for the feed and return of oil, water and other fluids.

  • design according to customer specifications
  • preferably with a corrugated section
  • with or without bending in the plain tube or corrugated section
  • compensation of vibrations, thermal expansions, fitting tolerances
  • technically gas-tight
  • temperature-resistant / corrosion-resistant thanks to suitable selection of materials

Pipes for Hydrogen and Fuel Cell Drives

Areas of Application

  • fuel cell, medium and low pressure range

Technical characteristics

  • customer-specific certified stainless steels
  • extreme safety: designed for pressures of 10-20 bar; burst pressure testing over 500 bar
  • 100% helium leak-tested components
  • customer-specific weld certificates and specific certificates of approval of welding power

Pipe Assemblies

The restricted mounting space in refrigeration systems, for example in the transformer oil cooling circuits, places high demands on the geometrical and technical characteristics of flexible assemblies.

  • compensation of thermal expansion and installation tolerances, decoupling of vibrations
  • heat and pressure-resistant due to selection of suitable materials and multi-ply construction
  • resistant to corrosive media or media elements due to selection of suitable materials

Pipe Assemblies in the Exhaust Gas Area

Pipe assemblies optionally consist of segment and/or bare pipe elbows from in-house production (up to DN 150) and can be manufactured with or without insulation. A bellows or stripwound hose is used as a flexible metallic element.

  • geometric and technical characteristics as well as the connection technology can be adapted to the particular customised mounting situation
  • temperature, pressure, corrosion and ageing-resistant

Exhaust Gas Return Pipes

Exhaust gas pipes help to reduce pollutant emissions from combustion engines in order to meet the strictest laws.

  • design according to customer specifications
  • preferably with a corrugated section
  • with or without bending in the plain tube or corrugated section

Exhaust Gas Return Pipes with finest filter

Exhaust gas pipes help to reduce pollutant emissions from combustion engines in order to meet the strictest laws.

  • design according to customer specification in the low pressure EGR range
  • preferably with silencer
  • with or without bending in the plain tube
  • connection via flange, V-band clamp connection, casting or deep-drawing parts according to customer specification
