Ductile baƙin ƙarfe bututuwani nau'i ne na kayan bututu da yawaana amfani da shi wajen samar da ruwa, magudanar ruwa, watsa iskar gas da sauran fannoni. Yana da halaye na babban ƙarfi, juriya na lalata da kuma tsawon rayuwar sabis. Diamita kewayon DNSEN ductile baƙin ƙarfe bututu neDN80～DN2600 (diamita 80mm ~ 2600mm),gabaɗaya mita 6 kuma ana iya keɓance su.Matsayin matsin lamba: yawanci zuwa nau'in T (ƙananan matsa lamba), nau'in K (matsakaicin matsa lamba) da nau'in P (matsi mai ƙarfi).Danna don samun kasida na bututun ƙarfe na ductile.
Don hanyoyin haɗin haɗin tsarin bututun ƙarfe, DINSEN ya taƙaita su kamar haka:
1.Haɗin soket nau'in T:Abu ne mai sassauƙa, wanda kuma ake kira nunin faifan faifai, wanda shine babban haɗin gwiwa don bututun ƙarfe na gida. Matsin lamba tsakanin zoben roba da soket da spigot yana samar da hatimi don ruwa. Tsarin soket ɗin yana la'akari da matsayi da kusurwar juyawa na zoben roba, zai iya daidaitawa zuwa wani tushe na tushe, yana da juriya na girgizar ƙasa, yana da halaye na tsari mai sauƙi,sauki shigarwa da kyau sealing, da sauransu. Yawancin bututun ƙarfe na samar da ruwa a kasuwa suna amfani da wannan hanyar sadarwa.
Takamaiman matakai: 1. Tsaftace soket da spigot. 2. Aiwatar da mai zuwa bangon waje na spigot da bangon ciki na soket. 3. Saka spigot a cikin soket don tabbatar da yana cikin wurin. 4. Rufe tare da zoben roba.
2. Haɗin soket mai ɗaure kai:Yana ɗaukar tsarin rufewa na nau'in T-type, wanda ake amfani da shi a cikin yanayi inda turawar ruwa ke gudana a lanƙwasa bututun ya yi girma sosai, ko kuma wurin ya yi girma da yawa, wanda ke haifar da faɗuwa cikin sauƙi. Idan aka kwatanta da nau'in nau'in nau'in T, zoben walda, zobe mai riƙewa mai motsi, flange na musamman da kuma haɗa kusoshi da aka haɗa akan ƙarshen spigot na bututu ana ƙara su don sa ƙirar ta sami mafi kyawun anti-pullout ikon. Zoben riƙewa da flange na matsa lamba na iya zamewa, ta yadda mahaɗin yana da ƙayyadaddun haɓakawa da ikon jujjuyawa, wanda za'a iya amfani dashi lokacin da ba za'a iya saita hujin ba.
3.Haɗin flange:Ta hanyar ƙarfafa kusoshi masu haɗawa, flange yana matse zoben hatimi don cimma hatimin mu'amala, wanda ke da tsauri. Yana da yawaana amfani da su a lokuta na musamman kamar haɗin haɗin haɗin bawul da haɗin bututu daban-dabans. A abũbuwan amfãni ne high AMINCI da kyau sealing. Ya dace da yanayin da diamita na bututu yana da girma ko tsayin bututu yana da tsayi, kuma ya dace da wuraren da ke da alaƙa da bututun bututu da buƙatun rarrabawa akai-akai. Duk da haka, idan an binne shi kai tsaye, akwai haɗarin lalata a kan kusoshi, kuma aikin hannu yana da tasiri mafi girma akan tasirin rufewa.
Takamaiman matakai: 1. Sanya flanges a ƙarshen bututun. 2. Ƙara gasket ɗin rufewa tsakanin flanges biyu. 3. Daure flange da kusoshi.
4. Arc walda:Ana iya zaɓar sandunan walda masu dacewa irin su MG289 na walda don yin walda, kuma ƙarfin ya fi na simintin ƙarfe. Lokacin amfani da bakar zafi waldi, preheat 500-700℃kafin walda; idan aka zaɓi sandar walda mai tushen nickel mai kyau mai filastik da tsayin daka mai tsayi, ana iya amfani da walda mai sanyi mai ƙarfi, wanda ke da yawan aiki, amma walƙar sanyi na arc yana da saurin sanyaya, kuma walda yana da haɗari ga tsarin farin baki da fasa.
5. Walda Gas:Yi amfani da wayar walda nau'in RZCQ, kamar waya waldi na baƙin ƙarfe mai ɗauke da magnesium, yi amfani da harshen wuta tsaka tsaki ko harshen wuta mai rauni, kuma sannu a hankali bayan waldawa.
Takamaiman matakai: 1. Tsaftace ƙarshen bututu. 2. Daidaita ƙarshen bututu da walda. 3. Duba ingancin walda.
6. Haɗin zare:An haɗa bututun ƙarfe mai ductile tare da zaren a gefe ɗaya zuwa haɗin gwiwa tare da zaren da suka dace.Ya dace da aikace-aikace tare da ƙananan diamita da ƙananan matsa lamba.Yana da sauƙin shigarwa da sake haɗawa, amma aikin hatiminsa yana da iyaka, kuma yana da manyan buƙatu don daidaiton sarrafa zaren da ayyukan shigarwa.
Takamaiman matakai don wasu hanyoyin haɗi: 1. Tsara zaren waje a ƙarshen bututu. 2. Yi amfani da mahaɗin zaren ciki don haɗawa. 3.Rufe shi da ɗanyen tef.
7.Haɗin zobe na roba: Shigar da zoben rufewa na roba a ƙarshen kowane ɓangaren bututu, sa'an nan kuma tura sassan bututu biyu a ciki kuma ku haɗa su tare ta hanyar haɗin turawa. Zoben rufewa yana tabbatar da aikin hatimin haɗin gwiwa daya dace da bututu tare da ƙananan diamita.
8.Haɗin zobe mai ƙarfi mai hana ruwa:Weld zoben tsayawar ruwa a kan bututun ƙarfe na ductile, kuma a jefa shi kai tsaye cikin yanki ɗaya yayin ginin katangar da aka ƙarfafa. Ana amfani da shi sau da yawa don haɗa bututun ƙarfe na ductile don magudanar ruwa tare da bango kamar rijiyoyin dubawa.
A takaice, ana iya zaɓar hanyar haɗin haɗin bututun ƙarfe bisa ga yanayin gini. Musamman,haɗin soket ɗin ya dace da bututun ƙasa, haɗin flange ya dace da lokatai waɗanda ke buƙatar rarrabuwa akai-akai, haɗin da aka haɗa ya dace da ƙananan bututun diamita, haɗin walda ya dace da yanayin matsa lamba da yanayin zafi, kuma haɗin injin ya dace da yanayin wucin gadi ko na gaggawa.
