Use to pipe friends should understand that in the winter is colder, in this environment is easier to use the cracking, which requires us to be insulation, thermal insulation material when bonding surface of the pipe must be debris, dust, oil clean up, in order to ensure adhesion of glue. Here is a brief introduction of its insulation measures: 1, plaster protective shell insulation jobs, Shi winter when water pipes freezing measures have to. 2, for insulation pipes and equipment should only be done after corrosion and water pressure test pass, and if do first insulation layer, the interface and the weld should stay out of the pipeline, to be qualified before the hydrostatic test interface insulation . 3, must be cleaned of debris inside the trench before the insulation tube wells clean of debris left over construction process, should be ready to clean up, to ensure the smooth flow of waste; 4, the ceiling and the building needs to be done within a tubewell pipe insulation, corrosion test pressure must be qualified, after the completion of the implicit seized qualified insulation, construction can finally be closed, non-reversed process of construction. Water supply pipe insulation design requirements and specifications shall be carried out, especially the thickness of the insulation layer according to design requirements, the practice does not allow unauthorized changes to the insulation, insulation adhesive should be used in reference to the product specification shall apply too much or too little. Note that you need to do the ceiling of the building insulation and pipe pipeline pressure test must be qualified in corrosion, insulation inspection pass after completing hidden, and then finally closed, non-reversed process of construction.
