Ngemuva komkhuba wokuthuthuka okusheshayo we-strip esezingeni eliphakeme ukukhiqizwa okuqhubekayo okuqhubekayo kanye nokuthuthukiswa kobuchwepheshe bokushiswa kukagesi, ukuthuthuka okuqhubekayo kwamapayipi we-welding, izinhlobo ezingama-316l zensimbi ezingenamibuncu zezimboni ziyanda, futhi zithathe indawo ethile emikhakheni eminingi. Thunga ishubhu. Enqubweni yokukhiqiza yamapayipi we-welded, ukuqiniswa kweWeld kungashiwo ukuthi kuyinkinga ebucayi kakhulu.
Ukuphakama kwe-welder ethe xaxa kwe-316l insimbi engagqwali yensimbi engenasici anezimboni ezihlaselwe izimbotshana ezifihlekile, ngokulandelayo:
.
Isihluthulelo sengcindezi ye-butt ehlanganisiwe sakhiwa ukuphakama kwe-welding, kanye nengcindezi ye-in-situ eWeld Toe ye-Butt Joition inkulu.
Ubukhulu bezinkomba zezinkomba zokucindezela yi-Weld Heate h, i-angle yokuhlangana θ ku-weld uzwane kanye ne-semi-warp r. Ukwanda kokuphakama kwe-welding h kukhulisa i-angle θ, futhi ukwehla kwenani kuzokwengeza inkomba yokucindezela.
Lapho kukhulisa ukuqiniswa kwe-Weld, kubaluleke kakhulu izinga lokucindezela, kepha amandla acindezelayo we-butt welding azokwehla. Ngemuva kokufudumala, faka ukuphakama okweqile, uma kuphakeme kune-butt weld, wehlisa ukucindezela. Kwesinye isikhathi kungandisa amandla acindezelayo we-butt welding. I-weld yangaphandle inokuphakama okukhulu okusalayo, okuzobeka engcupheni ukwanda kweshubhu ngemuva kokwanda kwengcindezi.
Lapho ipayipi eliqondile le-arc eqondile linwetshwa ngaphansi kwengcindezi, ipayipi lensimbi elingenamthungo ligoqwe ngokuya ngezikhunta zangaphakathi ezingenhla nakwesokudla ngodonga olufanayo lwangaphakathi kanye nokucaciswa kwamapayipi wensimbi. Ngakho-ke, uma ukuqiniswa kwe-weld kukhulu kakhulu, lapho ububanzi bunwetshiwe, ukucindezela kwe-shear okucatshangwe ukuthi iWeld ithambekele ku- 'imiphetho emincane eqondile ' kuzo zombili izinhlangothi ze-wever enkulu.
Kodwa-ke, okuhlangenwe nakho komsebenzi kuveze ukuthi lapho ukuqiniswa kwe-weld yangaphandle kuphethwe ngo-2mm noma ngaphansi, akulula ukuba namagadlandla amancane aqondile 'lapho ingcindezi inwetshiwe. Uhlobo lwepayipi akulula ukulimala. Lokhu kungenxa yokuthi ukuqiniswa kwe-wald yangaphandle kuncane, futhi ukucindezelwa kwe-shear okuthwalwa yi-butt weld nakho kuncane. Uma lolu hlobo lokuxineka lwe-shear luphakathi kobubanzi be-dectile deformation, ngemuva kokulayisha, kwakhiwa ukuqina, futhi ipayipi lamanzi libuyela kokujwayelekile.
.
Uma indawo yangaphandle yepayipi le-arc ye-arc
(3) Ubukhulu be-welding bangaphandle bukhulu, okungathandeki ukuvikela ukugqwala.
Uma indwangu yengilazi ye-epoxy isetshenziselwa ukulonakala nge-anti-corrision ngesikhathi somsebenzi, ukuphakama okwengeziwe komthungo we-wald yangaphandle kuzokwenza kube nzima ukucindezela ngokuqinile e-Weld Toe. Ngaphezu kwalokho, i-Welding Serving ephakeme bese kuthi ungqimba lwe-anti-corolusion kufanele lube khona, ubukhulu besendlalelo se-anti-torosion esijwayelekile kubalwa ngokususelwa ekupheleni kwesendlalelo.
Qhathanisa nohlobo lwangaphakathi lwe-scraper lwangaphakathi lwe-Weld Desal Opment, Hangao tech (seko mishini) Imishini yokufakelwa yomoya epholile ye-Airled ye-Weld inezinkambo ezimbalwa odongeni olungaphakathi lwepayipi lensimbi engenasici. Umgomo wayo wokusebenza ukusebenzisa i-mandrel eyakhelwe ngaphakathi ukuze uhlanganyele nokugoqa okufayo ukuze wenze ama-roll aphindaphindwe izikhathi ezingama-30 / imizuzu ku-Weld Seam yangaphakathi, ukuze i-wet sears ihlanganiswe kakhulu futhi nengcindezi incishisiwe.
Uma unezinkinga ezifanayo, sicela uthintane. Sijabule kakhulu ukukuphendula.
