Valves and Melt Pipes

Bleed Valves and Melt Pipe Systems at a Glance

  • Conical valves or cylindrical valves with proven design, electrically, oil or vapour heated
  • Design allows safe operation even after longer time of non-operation
  • Leakage free (conical) or very low leak rates (cylindrical), easy maintenance
  • Operation manually by manual torque driver or automatically by electrical or hydraulic drive
  • 2- and 3-way valves for melt pipe diameters up to 90 mm (others on request)
  • Melt pipes with electrical-, oil- or vapour heating
  • Including insulation and instrumentation (melt pressure, melt temperature)
  • Incl. static mixers if required
  • Melt pipe length without flanges up to 4 m, flanges also oil- or vapour heated
  • Design according to pressure vessel codes if required (AD2000, ASME)


Custom-made melt pipes

  • We design the melt pipe according to customer‘s application
  • Calculation of pressure drop, shear rates, residence time etc.
  • Layout and detailed design by our experienced engineering staff
  • Supply of complete melt systems incl. melt filters, melt pumps etc.
  • Manufacturing of melt pipes by certified welding companies
  • Quality assurance incl. pressure tests, weld seam inspections etc.
  • Assembly of insulation, instrumentation etc.
  • Supervision of on-site installation
