Rigid stainless steel flexible waterproof casing pipe through the wall of cold galvanized wall pipe manufacturers offer

Stainless steel waterproof casing Description: stainless steel waterproof casing used in corrosive media papermaking, sewage, pharmaceuticals, petrochemicals, crude oil, fuel oil, lubricating oil, refined oil, water, oil, acids, alkalis, etc., generally applies to pipe through the walls of the place by vibration or water tight structures required; wall at the wall, in case of non-concrete walls should switch to concrete and must be solidified in a flexible waterproof casing wall; stainless steel waterproof casing applied to the construction, chemical, steel, water, sewage treatment and other units. When the pipeline crossing foundation, walls, floors, etc., to avoid the pipeline (pressure pipes, such as water supply, heating, etc.), when used, causing disturbance to the building, at the same time flexible waterproof casing for easy installation and maintenance of the pipeline, set greater than the outer diameter of the pipe installation, material and length conform to the requirements of installed base, walls, floors and other pipeline crossing at the short tube. Stainless steel waterproof casing, the use of welding control into rebate ends should be mechanical (eg, toothless saws, etc.), strict requirements for thickness. Building "waterproof casing" pipeline crossing basement has water requirements, when structures, set up a special production casing. Commonly used rigid waterproof casing. Rigid waterproof casing, the need to weld the sleeve outer sealing ring wing, thickness, thickness of the sleeve of the ring-wing have strict requirements, and shall ensure that the weld quality. Pipe wear foundation concrete shear wall structure, through the beam, wearing special-shaped column, should be installed together with civil engineering. The reason is that after the reserve hole, the second pouring concrete between the casing and hard to deal with; some can not handle, such as the installation of rigid waterproof casing base basement concrete shear wall. Means the pipeline through concrete slabs, ordinary brick wall, usually reserved for holes in the concrete floor, ordinary brick can be eye after cutting off the wall. Floor office, before the security pipeline, out through the line, mounting sleeve. Brick wall, drawing a line, planted stented, find a good slope, mounting sleeve.
