What to pay attention to when welding the extended flexible waterproof casing
We all know that the length of flexible waterproof casing depends on the thickness of the wall it passes through, which is indisputable. With the diversified needs of buildings, the thickness of the wall varies, and the lengthened flexible waterproof casing has been improved on the basis of the original. Its excellent performance has won the favor of more and more users.
 
Since conventional welding cannot guarantee its stability and sealing waterproof performance, here I suggest you five points that should be noted when welding extended flexible waterproof casing:
 
1 . Please take off in advance when welding. Lower the flange gland and rubber seal of the flexible waterproof casing to avoid deformation or melting of the rubber seal due to high temperature during operation;
 
2 . Steel structure should ensure that the flexible waterproof casing stop ring centered, welding directly around the wing ring welding ;
 
3 . When the length of flexible waterproof casing is greater than the thickness of the wall, the concrete thickness can be partially thickened and lengthened outside the inner or outer wall;
 
4 . Pre-embedded welding to ensure a good seal inside and outside, there can be no water and debris into;
 
5 . If the welding part has been painted, the paint should be removed so that the flexible waterproof casing and welding rod and concrete effective combination; lengthened waterproof casing due to more contact with the concrete, large force area, production as far as possible in accordance with national standards.
