Xov txuas yog siv hauv qab DN100
DN50 ~ DN300 txais kev txuas clamp
Flange kev twb kev txuas yog saws rau saum DN50
DN100 tuaj yeem siv bimetal vuam
Cov kev sib txuas uas siv rau faus yas-coated hluav taws kav yog flange, clamp txuas thiab vuam. Ntawm lawv, welding yog txoj kev sib txuas zoo tshaj plaws. Vuam tuaj yeem siv bimetal thiab tsis muaj kev puas tsuaj, uas tuaj yeem tiv thaiv cov txheej txheem los ntawm kev puas tsuaj tom qab vuam. Thiab qhov tshwm sim ntawm cov raj xa dej tawg tau tshwm sim los ntawm geological subsidence hauv kev siv.
