Rigid waterproof casing production quality rules

Rigid waterproof casing production quality rules
In the pool installation, according to the atlas standard can be seen, there is no flange gland one end of the rubber ring is waterfront, is placed in the pool's inner end, with flange gland, rubber ring seal this end should be placed on the outside of the pool wall. So that the later pipe installation sealing outside the pool can be constructed, the later flexible waterproofing casing sealed maintenance inspection outside the pool is also more convenient to operate. Flexible waterproof casing installed in buildings that are not pools, such as pump rooms pipeline through the wall, this time should be flange gland rubber ring end facing indoors, because there is no waterproofing requirements, but only to play a shock and protect the role of the pipeline, flange gland seal end placed indoors, whether it is more convenient to install or later inspection and maintenance.
 
Rigid waterproof casing stop ring width design based on very simple and practical, on the width of the stop ring design alone is a unified standard, that is, according to the 02S404 drawing set size for material processing, different requirements of construction projects can also be specially customized, such as conventional rigid waterproof casing products stop ring is set in the middle position, while some need to be set near a section of 10 cm, some For thicker walls need to do lengthening treatment, and according to the actual lengthening situation to increase the wing ring, and the product's wing ring width is based on the product's standard. The national standard has a uniform size, there is a factory standard, that is, according to the degree of engineering requirements have been developed by manufacturers, such standards of the width and thickness of the water stop ring and tube thickness are slightly different from the national standard, but will be based on customer needs, let's say to save budget, but even so we will be in absolute assurance that the quality of the production of no problem.　Rigid waterproof casing according to the design requirements to determine the diameter of the pipe, that is, DN100 below the casing than the installation of pipe diameter 2, DN100 above the casing installation pipe diameter 1. According to 02S404 waterproof casing atlas size table to determine the thickness of the water stop steel plate, small diameter 10mm thick steel plate for the water stop wing ring, large diameter water stop wing ring according to the standard production 12, 14, 16, 20mm thick. The width of the wing ring is 50-80mm. water stop wing ring is welded on the steel pipe, double-sided welding, full weld, no porosity, no edge biting phenomenon, for the roof waterproof casing wing ring welding position should be 50-60m from the bottom of the casing. general through the wall rigid waterproof casing set, the casing length should be slightly shorter than the wall thickness 3 ~ 5mm, wing ring welded in the middle of the casing. Rigid waterproof casing polished smooth at both ends.
