The production process of flexible waterproof casing.

First of all, we must first understand the structure of flexible waterproof casing. Flexible waterproof casing has two wing rings, an upper plate, a gland, a tube body, retaining ring and, sealing ring and other parts. Flexible waterproof casing in the pipeline project, flexible waterproof casing is mainly used for the connection of the pipeline. In the need to connect the pipeline, a variety of installation of a piece of flange, low-pressure pipeline can use the silk flange, the two pieces of flange between the gasket, and then fastened with bolts. Flexible waterproof casing can be widely used in a variety of transmission machinery in the reduction of transmission, such as metallurgy, mining, lifting, chemical, construction rubber ships and other industries, as well as other mechanical equipment, flexible waterproof pipe sleeve shaft can be positive and negative rotation.
When making the flexible waterproof casing interface, the location, coordinates, elevation and size of the reserved holes should be checked in accordance with the requirements of the construction drawings; installation, despite the length and slope of the cut pipe control within the prescribed range, but if improperly installed, leakage can still occur.
Check all pipes for cracks, trachoma and uniformity of pipe wall thickness.
Flexible waterproof casing suitable for drinking water pool waterproof casing installation, after the completion of asbestos cement filling hit, filling sealing paste, should ensure that all contact surfaces in the seam without rust, paint skin, dirt, and clean, dry. The flexible waterproof casing is generally used for structures that are subject to vibration or have strict waterproofing requirements where the pipe passes through the wall.
