Qhov zoo ntawm Ductile Iron Pipe Rubber Ring Interface

Kev siv cov yeeb nkab hlau thiab roj hmab nplhaib interface muaj qhov zoo hauv qab no:

① Cov kav dej hlau muaj qhov elongation siab, thiab cov kabmob siab ntawm K9 cov kav dej tuaj yeem ncav cuag 6MPa;

② Cov kav dej hlau tsis yooj yim rau kev tsim hluav taws xob vim lawv qhov kev tiv thaiv siab, thiab lawv txuas nrog cov roj hmab sealing nplhaib nrog rwb thaiv tsev ua haujlwm, yog li lawv muaj hluav taws xob tiv thaiv corrosion, thiab muaj cov txiaj ntsig zoo hauv daim ntawv thov nyob rau hauv qhov chaw uas muaj ntau yam stray tam sim no. ;

③ Cov yeeb nkab hlau muaj zog qaug zog zoo, kev ua haujlwm zoo, tsis muaj nqi thiab tsim khoom yooj yim;

④ Sab nrauv ntawm nodular cam khwb cia hlau yeeb nkab yog txau nrog zinc thiab asphalt xim, thiab sab hauv tuaj yeem ua cov cement, uas tuaj yeem tsis tsuas yog txhim kho nws cov kev ua tau zoo, tab sis kuj tiv thaiv cov dej zoo, yog li nws tuaj yeem hloov mus rau hauv av noo ib puag ncig. thiab ncua kev pab cuam lub neej ntawm cov yeeb nkab;

⑤ Cov yeeb nkab hlau siv tau hloov pauv tau, thiab cov yeeb nkab sib txuas tuaj yeem hloov tau, yog li nws yooj yim heev rau nruab rau hauv qhov chaw ntawm txoj kab nruab nrab ntawm txoj kab nkhaus.
