Description

TECH Pipe Section MT 4.1 is the preformed concentric-rolled stone mineral wool pipe section for the insulation of industry process pipelines for diameters from 12.7 mm to 254 mm (1/2'' to 10''), exhaust ducts and stacks. Pre-slit to facilitate the opening and fitting over the pipes, TECH Pipe Section MT 4.1 are easy to handle. With a length of 1.2m, installation time on straight pipes and thermal bridges can be reduced by 20%.

 TECH Pipe Section MT 4.1 can be used for service temperatures of up to 650°C.

Key Benefits

  • Sound absorption
  • High service temperatures
  • Fire reaction
  • Mechanical resistance
