Ipayipi lensimbi elijikelezayo lenziwa ngokugoqa insimbi yesakhiwo enekhabhoni ephansi noma umugqa wensimbi wesakhiwo one-alloy ephansi ibe yipayipi, ngokwe-engeli ethile yomugqa ojikelezayo (obizwa ngokuthi i-forming angle), bese kushiselwa imithungo yepayipi.
Ingasetshenziswa ukukhiqiza ipayipi lensimbi elinobubanzi obukhulu ngensimbi encane.
Ukucaciswa kwepayipi lensimbi elijikelezayo kuvezwa ubukhulu bodonga obungaphandle * ububanzi.
Ipayipi elihlanganisiwe kufanele lihlolwe ngokuhlolwa kwe-hydrostatic, amandla okunamathela kanye nokugoba okubandayo, ukusebenza komthungo wokunamathisela kufanele kuhlangabezane nezidingo zencazelo.
Inhloso eyinhloko:
Ipayipi lensimbi elijikelezayo lisetshenziswa kakhulu ekudlulisweni kukawoyela negesi yemvelo.
Inqubo yokukhiqiza:
(1) Izinto zokusetshenziswa: ikhoyili yensimbi, ucingo lokushisela kanye nokushintshashintsha. Ukuhlolwa okuqinile ngokomzimba nangokwekhemikhali kufanele kwenziwe ngaphambi kokukhiqizwa.
(2) Ukushisela isinqe ikhanda nomsila wekhoyili ukuze kwenziwe amakhoyili amabili ahlanganiswe, bese kusetshenziswa ukushisela i-arc engaphansi komhlaba ngentambo eyodwa noma izintambo ezimbili, bese kusetshenziswa ukushisela i-arc engaphansi komhlaba ngokuzenzakalelayo ukuze kushiselwe ngemva kokugingqika epayipini lensimbi.
(3) Ngaphambi kokwakheka, insimbi kufanele ilinganiswe, inqunywe, ihlelwe, ihlanzwe indawo, ithuthwe futhi igotshwe kusengaphambili.
(4) Igeyiji yokucindezela kokuxhumana kagesi isetshenziselwa ukulawula ingcindezi yesilinda kawoyela ecindezelayo ezinhlangothini zombili ze-conveyor ukuqinisekisa ukuthuthwa kwensimbi eqoshiwe kahle.
(5) Ukuze uhlele umqulu, sebenzisa ukulawula kwangaphandle noma ukulawula kwangaphakathi.
(6) Sebenzisa idivayisi yokulawula igebe lokushisela ukuqinisekisa ukuthi igebe lokushisela lihlangabezana nezidingo zokushisela, khona-ke ububanzi bepayipi, ukungalungi kahle kanye negebe lokushisela kungalawulwa ngokuqinile.
(7) Kokubili ukushisela kwangaphakathi kanye nokushisela kwangaphandle kusebenzisa umshini wokushisela we-American Lincoln Electric we-single wire noma izintambo ezimbili ezifakwe ngaphansi kwe-arc welding, ukuze kutholakale ukusebenza okuzinzile kokushisela.
(8) Zonke izithungo zokushisela zihlolwa yisitholi seziphambeko ezizenzakalelayo ze-ultrasonic esiqhubekayo ku-inthanethi ukuqinisekisa ukuthi ukuhlolwa kwe-NDT okungu-100% kuhlanganisa zonke izithungo zokushisela ezijikelezayo. Uma kukhona iziphambeko, kuzoxwayisa ngokuzenzakalelayo futhi kufake amamaki okufafaza, futhi abasebenzi bokukhiqiza bazolungisa amapharamitha enqubo nganoma yisiphi isikhathi ukuze kususwe iziphambeko ngesikhathi.
(9) Ipayipi lensimbi lisikwa libe yingcezu eyodwa ngomshini wokusika.
(10) Ngemva kokusikwa kube yipayipi elilodwa lensimbi, inqwaba ngayinye yepayipi lensimbi izobe ingaphansi kohlelo lokuhlola lokuqala oluqinile ukuze kuhlolwe izakhiwo zemishini, ukwakheka kwamakhemikhali, isimo sokuhlanganiswa, ikhwalithi yobuso bepayipi lensimbi kanye ne-NDT ukuqinisekisa ukuthi inqubo yokwenza ipayipi iyafaneleka ngaphambi kokuba isetshenziswe ngokusemthethweni.
(11) Izingxenye ezinezimpawu zokubona amaphutha aqhubekayo e-acoustic kumthungo wokushisela zizohlolwa kabusha nge-ultrasonic kanye ne-X-ray. Uma kukhona amaphutha, ngemva kokulungiswa, ipayipi kufanele liphinde libhekane ne-NDT kuze kube yilapho kuqinisekiswa ukuthi amaphutha asusiwe.
(12) Ipayipi lomthungo wokuwelda we-butt kanye nomthungo wokuwelda we-spiral ohlangana ne-T-joint kufanele uhlolwe ngokuhlolwa kwethelevishini ye-X-ray noma ifilimu.
(13) Ipayipi ngalinye lensimbi lingaphansi kokuhlolwa kwe-hydrostatic. Ingcindezi nesikhathi sokuhlola kulawulwa ngokuqinile yidivayisi yokuthola ikhompyutha yengcindezi yamanzi epayipi lensimbi. Amapharamitha okuhlola aphrintwa futhi aqoshwe ngokuzenzakalelayo.
(14) Isiphelo sepayipi senziwe ngomshini ukuze silawule ngokunembile ukuthambekela, i-angle ye-bevel kanye nobuso bempande.
