②After completion, the tools should be cleaned and maintained.
(4) Five points for gasket installation
①The right choice: the form, material and size of flanges, bolts and gaskets should be selected according to the operating conditions and the structure of the flange surface.
②The inspection is detailed: the quality of flanges, bolts, nuts, and gaskets should be carefully checked before installation, and there should be no defects such as burrs, unevenness, and cracks. Carefully check the installation of flanges and pipes, and there should be no deviations, wrong openings, etc. Phenomena such as wrong holes.
