Introduction: When the waterproof sleeve is installed, it needs to install the sealing pipe fittings. What standards should the waterproof sleeve meet when installing the sealing pipe fittings, what should be paid attention to during the installation, and how to install correctly: when installing the sealing pipe fittings of the waterproof sleeve and flexible waterproof sleeve

Waterproof casing In the case of installation, sealing pipe fittings need to be installed. What standards should be met for the waterproof sleeve when installing the sealing pipe fittings, what should be paid attention to during the installation, and how to install correctly: when installing the waterproof sleeve, Flexible waterproof casing When sealing the pipe fittings, the smoothness of flange and gate valve convex surface and sealing gasket shall meet the requirements, and the defects such as scratch and black spot affecting the sealing characteristics shall not be allowed, and white vaseline shall be coated.
Specification and material condition of standard parts, carefully check the material, specification and size of bolts in drawings. Alloy steel bolts and nuts are selected for high and low temperature medium, and molybdenum disulfide is applied to some special positions. Before installation of high pressure flange, it is necessary to check whether there are axial scratches and rust on the trapezoidal groove. For the defects, it must be grinded by professional technicians (fitters), which can not be solved by themselves. During installation, wipe the tank body with fine gauze, then put the metal ring pad into the tank body, rotate 450, and check the tightness of the contact line and trapezoidal groove with red lead oil, without interruption. Whether the gasket class meets the requirements, for different media, temperature and pressure, choose different gasket. For the high pressure pipeline with specified tightening regulations (torque and prestress), special hydraulic torque wrench or hydraulic bolt stretcher shall be selected for tightening according to the pre tightening force or torque moment.
The product can be used as a kind of hardware pipe fittings for the areas with high waterproof requirements at the wall. The surface treatment of flexible waterproof casing is also the main factor of pipeline anti-corrosion. Therefore, for today's casing, rust prevention treatment should be done well. In case of rust prevention, several aspects should be considered. First of all, it is necessary to do a good job in cleaning up the surface of steel by using solvent, which can remove grease and rust on the surface of steel, which is an auxiliary way in anti-corrosion production. Two anti rust finish coat and waterproof finish coat are required for each casing. Before the construction process, we have always been that regulation, and also do that. The positions where the waterproof sleeve and the structural concrete touch each other are painted, which leads to the inseparable combination with the structure. It is felt that the joint position with the structural concrete only requires derusting.
