VML pipes as a compound pipe system
The VML pipe is a clean, stable and simple alternative to the elaborate insulation of pipeline parts that are subject to water condensation or frost. The compound pipe system has an excellent thermal insulation and protection from water condensation for a standard environmental temperature of 25°C and an admissible relative humidity below 75%. An accompanying heating is available as a special version. The smooth galvanised steel plate (also available as stainless steel plate) protects reliably from mechanical attacks. The push-in connection is pre-installed with integrated flange rings, which are linked thrust-resistant with profile clamps of galvanised steel.
