Cangzhou waterproof casing waterproof casing waterproof casing selection techniques characteristic Gongyi Hua Yang pipeline

DN900 and DN500 cast iron pipes should be used for what types of models of rigid waterproof casing the first to know A rigid waterproof casing is not used to wearing a cast iron pipe, and therefore should be used B or C rigid waterproof casing. Rigid waterproof casing B and C DN500 are wearing an outer diameter 528 and an outer diameter of 532 cast iron pipe ductile iron pipe, rigid waterproof casing B and C DN900 are wearing cast iron tube diameter and 939 an outer diameter of 945 ductile iron pipe. distinction B and C type rigid casing casing is different casing material itself, B-type casing made of carbon steel Q235-A, and C-type casing itself is made of HT150 cast iron. In addition, within the A DN500 rigid waterproof casing wear an outer diameter of 530 steel or PVC tube, DN900 the A rigid waterproof casing wear outer diameter of the pipe or PVC pipe 920, A-type casing material is Q235-A carbon steel, and B the same material. 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.
