ABM Rockwool Pipe Section is made of rock wool fiber, preformed through some mould and cured by high temperature. For easy installation, the pipe section is split in one side with a joint cutting on the opposite side along with the axis of the pipe. It makes pipe section tightly fit with pipeline. The outer face of the pipe section can be polished to make the consistent and exact insulation thickness in all directions or faced with aluminum glass cloth [ALGC).
