Njengezakhiwo ezinhle kakhulu zamapayipi ensimbi ezingagqwali ziya ngokuya aziswe kabanzi, amapayipi ensimbi angenasici abelokhu asetshenziswa kabanzi ezimbonini ezahlukahlukene. Kodwa-ke, ngenxa yezindleko zokukhiqiza, amapayipi wensimbi engagqwali anokusebenza okuqhathaniswa namapayipi ensimbi angenasici futhi amukelwa kabanzi. Hangao tech (seko mishini), onayo iminyaka engama-20 yesipiliyoni ekwakhiweni kwezimboni eziqhakazile I-Stainless Steel Pidlo yeWelld Weld Bead Ringing Umshini Womshini Wokugibela , Namuhla sethula izinyathelo zokuphepha zemisebenzi ye-welding, ukuze ukwazi ukuthola ukumelana okungcono kokugqwala kwamapayipi ensimbi engagqwali.

Ingxenye eyodwa
1. Ungalokothi ukhiphe i-arc ngezikhathi ezithile ebusweni bemicu yensimbi engenasici, uma kungenjalo kuzodala ukushiswa kwasendaweni ebusweni bepayipi. Ukushiswa kwasendaweni ebusweni bamapayipi kungumthombo wokugqwala, ikakhulukazi Ulayini wokukhiqiza wensimbi ongagculi odinga ukusetshenziselwa izimboni ezidinga ukumelana okuphezulu okuvumayo, njengokuphuza, imithi, uwoyela negesi, nokunye.
2. Nakisisa ukuguqula ijubane lokusebenza lomugqa wokukhiqiza. Uma uphishekela ngephutha ngejubane elikhulu futhi unganaki ikhwalithi ye-welding, umphumela we-welding uzokweneliseka.
I-3. Induku ye-welding esetshenziselwa ukufudumala kwe-tack belding kufanele ifane nenduku ye-welding esetshenziswe ngesikhathi se-welding, futhi ngokuphelele ayivunyelwe ukuyifaka esikhundleni se-rod yensimbi yensimbi enqola.
4. Ngaphambi kokuthi kukhishwe umucu wensimbi engagqwali futhi kufakwe insimbi, noma ngemuva kokudalwa kushubhu, akumelwe kube nezitica, amamaki we-arc, amabala, kanye ne-slag crust ngemuva kokushiswa kwe-welding ebusweni. Ngaphandle kwalokho, lokhu kuzokwengeza ukugcwala komhlaba wensimbi engenasici, okufanele kubhekwe. Singafaka idivaysi esezingeni eliphakeme ekugcineni kwengxenye yokwakha. Lesi sakhiwo esincane singasiza ekususeni ama-burrs emiphethweni yemithi, futhi ngasikhathi sinye senze umucu wokubushelela futhi kube lula ukuwathola.
5 I-tube yensimbi engagqwali ngemuva kokuvela okugqamile akukwazi ukuqeda ukucindezela okungatheni. Ngemuva kokunxusa, ifilimu eliminyene futhi elinomfaniswano futhi lingakhiwa ebusweni bepayipi lensimbi ukuvikela insimbi yangaphakathi kwi-oxidation kanye nokugqwala.
Ingxenye emibili
I-6. Lapho i-welding isiqediwe noma iphazamisa, ukuze igweme ama-craters arc noma imifantu, ama-craters we-arc kufanele agcwaliswe.
7. Lapho i-welding, i-weldentiment kufanele ibe nokuxhumana ngocingo olusondelene nokugwema ukuxhumana kabi phakathi kwe-weldenting kanye nentambo yomhlabathi, okuholela ekushisweni kwensimbi engenasici futhi kuthinte ukumelana kwayo kokugqwala.
8. Ukuze uvikele ikhabhoni noma okunye ukungcola kusuka ku-weld ngesikhathi se-welding futhi kuthinta ukumelana nokugqwala kwezinsimbi zensimbi engagqwali, kungcono ukuhlanza umucu wensimbi ngaphakathi kwama-20 ~ 30mm ezinhlangothini zombili ngaphambi kokushiswa. Ungakhetha ukufaka idivaysi yesingeniso evuselelayo ekugcineni kwangaphambili kwesigaba se-Welding.
9. Lapho ugcina noma uhambisa umucu wensimbi engagqwali, akukuhle ukukufaka ngensimbi ejwayelekile ukugwema ukungcoliswa ezinye izinkawu nokunye ukungcola.
10. Gwema ukuklwebheka noma ukuklwebheka ebusweni bamapayipi wensimbi engenasici lapho ekhona imishini yepayipi yezimboni yokucutshungulwa. Ungqimba oluvikelayo lwe-cushioring cushioning lungasongelwa kwi-rack yokulayisha.
Ingxenye yesithathu
11. Lapho ipayipi lensimbi engenasici liqonde, kwenqatshelwe ngokulingisa ngokuqondile ngesando ukugwema ama-dents ngaphezulu kwepayipi. Ngaphandle kwalokho, ukumelana kwawo ukugqwala kuzothinteka kakhulu.
12. Kuhle ukusebenzisa ukucindezela okubandayo ukwakha ikhanda le-seal nezinye izingxenye zesitsha, kunokuba kucindezelwe okushisayo. Uma kwakhiwa ama-Hot Press ekwakheni, izinguquko ekuphindisweni kokugqwala kufanele zihlolwe futhi ukwelashwa okushisa okuhambisanayo kufanele kwenziwe.
14. Lapho insimbi engenasici ifakwa ngaphansi kokwelashwa okushisa ngemuva kokushisa, akufanelekile ukushiya uwoyela kanye nokunye ukungcola ebusweni bensimbi ngaphambi kokushisa. Kufanele ihlanzwe ukugwema ukuqeqeshwa ngesikhathi sokushisa. Ngaphandle kwalokho, ngeke kuthinte kuphela umphumela we-annealing, kepha futhi kunciphisa impilo yezisetshenziswa zesithando se-annelling futhi kwandise izindleko zokulungisa. Cabanga ukungeza idivaysi yokuhlanza neyomiswa ngaphambi kwenqubo yokuvuselela. Idivayisi isebenzisa amanzi ashisayo ukuhlanza ingaphezulu lepayipi, bese ngokushesha lome umbhobho ngommese womoya ukugcina ubuso bepayipi buhlanzeke futhi bomile. Izinga lokushisa lokushisa kumele lifane. Lapho wenza ukwelashwa kokusiza kwengcindezi ngenhla kwama-800 ~ 900 ℃, izinga lokushisa kufanele liphakanyiswe kancane ngaphansi kwama-850 ℃. Kodwa-ke, lapho izinga lokushisa lifinyelela ku-850 ° C noma ngaphezulu, ukukhuphuka kwezinga lokushisa kufanele kube okusheshayo ukugwema ukuthambekela kokusanhlamvu zekristali ukwanda.
15. Ukwelashwa komhlaba kwamapayipi ensimbi angenasici njengokuphamba, ukupenda, ukukhatha nokuphambukisa kudinga ukuthathwa ngokungathi sína. Inqubo yokwelashwa kumele ihambisane nezinqubo zokusebenza. Izinga ukuthi ingaphezulu lensimbi liyi-silvery emnyama.
