The product is heat shrinkable patch with shrinkable≥15%m and a stater,which is usually applied to repair the large-scale  damage or defect of the duct or anticorrosion layer.

It is applied to the anticorrosion works on the pipelining site with satisfactory effed,which has been proved in many pipeworks.

Used together with high quality hot-meit adhesive and primer,the proved of our company is able to adapt to different kind of operating temperature,with strong oreep resistance and a service life as long as that of the pipe.
