Flexible waterproof casing type flexible waterproof casing pipe factory direct Gongyi Hua Yang

Flexible waterproof casing waterproof seals on how to install a flexible rubber ring before using the casing for inspection, not a split, crack, dislocation, mismatch, flash and so on. The surfaces in contact with the rubber ring should be clean, set in the wall pipe rubber ring should be straight, without distortion, you should set the necessary pipe supports and buttresses near the structure (building) buildings at the wall, in order to ensure wear When the pipe wall to the uniform mounting rings, flange sleeve and flange gland axis concentric gap, and rubber ring sealing performance and service life, bolts and other fasteners should be set on the side of easy manual operation, the bolts should be symmetrical low tightened. DN1500 parameters 02S404 flexible waterproof casing waterproof casing above the flexible waterproof casing portfolio is the largest model DN1000 and DN1000 and rigid waterproof casing over there DN1200,1400,1600,1800,2000. DN1000 is greater than the actual production of flexible waterproof casing generally in accordance with the same type of rigid waterproof casing wear tube diameter do, and wing ring, tube thickness is slightly larger than DN1000. But DN1500 flexible waterproof casing that according to what criteria do? Because there is no rigid waterproof casing part DN1500 parameters. In this case only in accordance with the actual pipe diameter design and production, 1520 DN1500 pipe diameter, and therefore made out of flexible waterproof casing diameter must be greater than 1520, but not too big. The actual production casing diameter is generally to do by 1530, so wear tube 1520 without any problems.
