Te whakamahi paipa whakamahanangongo maitai tuituikia whakamahia hei fehokotaki'anga, i roto i te tua ki te whakamahi ka hono ki te taputapu, vaolo flanged hononga miro ranei.hau fehokotaki'anga whakamahi diameter iti iho i te 5omm, diameter nui ake i te 5omm whakamahi fehokotaki'anga.Kei te whakamahia te paipa paipa i roto i te pouaka whakamātao, ina tika mo te whakaurunga me te tiaki, ka whakamahia te hononga flanged, miro ranei.Ko te whakamahi i te mata convex flat fehokotaki flange tapawha flange whatukuhu-āhua ranei, ka hono flange, gaskets ki te matotoru o te 1 ~ 3mm hinu rapa asbestos, me te whakarerekētanga o graphite pani ki te hinu.I te hononga miro, me whakamahi koe i te penehīni, te kahinihi ranei hei horoi i te hinu i runga i nga miro, katahi ka pania ki te glycerol ki te whakakotahi i te kai pumukawai, te riipene Teflon ranei hei takai kekeno, ka aukati i te whakamahi mata hei hinu harakeke me te hiri.

He iti iho i te 25 mm te diameter o te putorino whakamahana freon me te putorino parahi, he maha nga tikanga hononga.

(1) nga waahanga parahi kua oti.te puka atanga mo te momo turanga, hononga brazing.

(2) turanga hono e te parahi brazing, te annealing kia tuatahi putorino mutunga, a ka whakawera i te pokepokea ai ki te turanga, kia nui ake te diameter turanga i te diameter o waho o te ngongo kōkuhu 0.25 ~ 0.5mm, te turanga whaimana hohonu taea e e rite ana ki te diameter o te paipa, te ahunga whakapuru Te titiro ki te rere reo.

(3) hononga flange.E ai ki nga whakaritenga hoahoa me nga ahuatanga motuhake, ka taea te whakamahi i nga mahi whakaurunga pipeline mo te parahi me te parahi koranu putorino flange flange wewete, fehokotaki'anga mowhiti flange wewete me flange paiherea, paiherea puka hononga flange.
