Supply stretch waterproof casing

Divided into two kinds of rigid and flexible waterproof casing. Selection should pay attention to: the waterproof casing is developed and designed under the Building Research S312, 02S404 standard atlas manufacturing. Rigid waterproof casing for the installation of drinking water pond waterproof casing, asbestos-cement fill after the fight finished, fill in embedded sealant, should ensure that the seam within the contact surface no rust, paint, dirt, and clean, dry . Flexible waterproof casing is generally applicable in the place of the pipe through the wall by vibration or strict water requirements of the structures; through the wall at the wall, in the case of non-concrete should switch to concrete walls, and must casing once solidified in the wall within; waterproof casing applied to the construction, chemical, steel, water, sewage treatment units. 
 Waterproof casing Category: 
 Flexible waterproof casing, rigid waterproof casing, steel flexible waterproof casing, both sides of the protective rigid airtight casing 04FS02 flexible airtight casing, the elongated flexible waterproof cover, stainless steel, waterproof casing. 
 Waterproof casing instructions: 
 A flexible filler materials: bitumen, flax, polystyrene board, PVC foam board. 
 Sealant: polysulfide sealant, polyurethane density on cream 
 Casing wear the wall at the case of non-concrete walls, the local switch to the concrete wall, its casting range to fly large ring diameter (D5) 200 and the casing must be first poured solid in the wall. 
 Wearing a tube at the concrete wall thickness should be less than 300, otherwise the side of the thicker wall or thickening on both sides of the diameter of the thicker part at least to D5, to +200. 
 The weight of the casing to L = 300 such as wall thickness greater than 300, should be calculated separately. 

 - Pipeline crossing based on interior walls, floors, etc., to avoid pipeline (pressure pipelines, such as water supply, heating, etc.) to buildings caused by disturbance, while allowing the installation and maintenance of the pipeline, setting, greater than installation of the pipe diameter, material and length to meet the requirements, installed in the foundation, interior walls, floors and other pipeline crossings of short tubes. 
 - Ordinary casing, multi-purpose welding control into the casing at both ends shall be mechanical (such as cut mouth, toothless saws, etc.), the strict requirements of wall thickness. Waterproof casing 
 - Pipe through the basement, and other water requirements of buildings, structures, set up a special production casing. Commonly used in rigid waterproof casing. 
 - Rigid waterproof casing, need to be welding outside of the casing seal ring wing, the wall thickness of the casing, the wall thickness of the ring-wing, there are stringent requirements, and shall ensure that the weld quality. 
 - New stretch waterproof casing, custom-made for the thicker wall stretch waterproof casing, to meet the thick wall, wearing a tube requirements. 
 - Anti-corrosion waterproof casing, the special treatment of the anti-corrosion coatings waterproof casing, effectively preventing the oxidation and corrosion of the waterproof casing.
