U TECH Pipe Section MT 4.0 is the efficient and light alternative for the insulation of industry process pipelines for standard pipe diameters from 15 mm to 356 mm (1/2'' to 14''). The ULTIMATE mineral wool preformed concentric-rolled pipe section is equipped with a pre-slit to facilitate the opening and fitting over the pipes. 

U TECH Pipe Section MT 4.0 are light and easy to handle. With a length of 1.2 m, installation time on straight pipes and thermal bridges threw joints can be reduced by 20 %. 

U TECH Pipe Section MT 4.0 can be used for service temperatures of up to 660 °C.

Key Benefits
