Stainless steel waterproof casing

Stainless steel waterproof casing generally applies to pipe through the wall at by vibration or leak water requirements structures; through the wall at the wall, in case of non-concrete should switch to concrete walls, and must be flexible waterproof casing once solidifiedstainless steel waterproof casing applied to the wall; construction, chemical, steel, water supply, sewage treatment and other units.
  Piping through the foundation, interior walls, floors, etc., to avoid pipeline (pressure pipes, such as water supply, heating, etc.) the use of the building, causing a disturbance, flexible waterproof casing to facilitate the installation and maintenance of the pipeline, set outer diameter greater than the installed pipeline, material and length to meet the requirements of the short tube installed in the foundation, interior walls, floors, and other pipeline crossings.
Stainless steel waterproof casing, the use of welded tubes, both ends should a mechanical cutting mouth (eg, using tooth saws, etc.), the wall thickness requirements lax. The waterproof casing pipe through the basement has water requirements of buildings, structures, set production casing. Commonly used rigid waterproof casing.
Rigid waterproof casing, need welding seal ring wing outside the casing, the wall thickness of the casing, the wall thickness of the ring-wing has strict requirements and ensure the quality of the weld.
Pipeline wear the basis of the shear wall of concrete construction, wear the beam, to wear special-shaped columns should be installed together with the civil works. The reason is reserved holes, secondary between the casing and the concrete pouring bad; Some can not handle, such as the basement foundation concrete shear walls installed on rigid waterproof casing.
Refers pipeline through the concrete floor, ordinary brick wall, are generally reserved holes in the concrete floor, ordinary brick wall can chisel through the wall of the eye. Floor office, before Ann pipeline, off the pass line, install the casing. Brick wall, drawing a line, planted set bracket, find a good slope, installing casing.
