Protective closed casing type A
The protective closed casing type A is a building prefabricated pipe fitting mainly used for hardware pipes. The protective casing type A is mainly composed of: steel casing, wing ring, and is suitable for pipes with steel-plastic composite pipes. A wing ring is welded to the outside of the casing. The casing is cast in the civil air wall through the wing ring. Its outer casing is cast on the wall at one time, the pipe passes through the middle of the casing, and the outer diameter of the pipe is sealed with the packing between the casing. Waterproof.

[product specifications]: DN32-DN1800
[Product Certification]: ISO 9001-2008
[Scope of application]: underground engineering, chemical, steel, construction, chemical, steel, tap water
[product material]: carbon steel, stainless steel, ductile iron
The protective closed casing type A is suitable for waterproofing the wall through the wall; it is mostly used for filling linseed and asbestos cement. The casing must be fully welded to both sides of the wing ring, and the weld is full, smooth, smooth, free of slag inclusions, no bubbles, no cracks, etc. During installation, the ends of the casing shall be clamped and fixed firmly by three or more bars, and shall not be skewed.
The protective closed casing type A is suitable for structures (buildings) that do not withstand pipeline vibration and expansion and deformation at the pipeline wall. For areas with seismic fortification requirements, such as rigid waterproof casings, should enter the pool wall or outside the building. A flexible connection is provided on the wall of the wall, and the type A is suitable for the steel pipe.
