Zambiri

Chiyambi cha Zamalonda

Mitundu yosindikizira yamtundu wa neck butt welding flange ndi:
RF, FM, M, T, G, FF.
Ubwino:
Kulumikizana sikophweka kupunduka, kusindikiza kwake ndikwabwino, ndipo kumagwiritsidwa ntchito kwambiri. Ndi yoyenera mapaipi omwe amasinthasintha kwambiri kutentha kapena kuthamanga, kutentha kwambiri, kuthamanga kwambiri komanso kutentha pang'ono, komanso mapaipi onyamula zinthu zotsika mtengo, zoyatsira ndi zophulika, komanso mpweya wapoizoni.
Zoyipa:
Chowotcherera khosi la khosi ndi chokulirapo, chokulirapo, chokwera mtengo, komanso chovuta kuyiyika ndikuchipeza, kotero ndikosavuta kugunda panthawi yamayendedwe.

Pali machitidwe awiri muyezo wa khosi matako kuwotcherera flange ku China: imodzi ndi dongosolo European, ndi zina ndi dongosolo American. The pazipita kuthamanga kukana wakhosi matako-kuwotcherera flangemu dongosolo European ndi 25Mpa, ndi pazipita kukanikiza kukana mu dongosolo American ndi 42Mpa.

Flange yowotcherera matako imatchedwanso khosi lalitaliflange. Ndizosiyana ndi flange yowotcherera yosalala chifukwa pali khosi lalitali komanso lopendekeka lalitali kuchokera pamalo owotcherera a flange ndi chitoliro kupita ku mbale ya flange. Makulidwe a khoma la gawo ili la khosi lalitali pang'onopang'ono amapita ku makulidwe a khoma la chitoliro motsatira njira ya kutalika, zomwe zimapangitsa kuti kusokonezeka kwapang'onopang'ono kuwonjezere mphamvu ya flange.

Ma flanges amawotcherera matako amagwiritsidwa ntchito makamaka m'malo omwe malo ogwirira ntchito amakhala ovuta kwambiri, monga momwe kupanikizika kumachitikira.flangendi lalikulu kapena kupsinjika maganizo kumasintha mobwerezabwereza chifukwa cha kuwonjezereka kwa kutentha kwa payipi kapena katundu wina, mapaipi ndi kusinthasintha kwakukulu kwa kuthamanga ndi kutentha, kapena mapaipi omwe ali ndi kutentha kwakukulu, kuthamanga kwambiri ndi kutentha kochepa pansi pa ziro. Kuwotcherera matako sikophweka kupunduka, kumamatira bwino, ndipo kumagwiritsidwa ntchito kwambiri. Kuthamanga mwadzina ndi PN1.0MPa~PN25.0MPa.
