I-Spiral Welded Pipe

(1) Imathiriyeli ekrwada zizikhoyili zentsimbi, iingcingo zokuwelda, kunye ne-fluxes.Ukuhlolwa okungqongqo ngokomzimba kunye neekhemikhali kuyafuneka phambi kotyalo-mali.

(2) Impundu edityanisiweyo yentloko yentsimbi kunye nomsila, yamkele intambo enye okanye ucingo oluphindwe kabini oluntywiliselwe i-arc ukuwelda, emva kokubhijela kumbhobho wentsimbi, yamkele ukuwelda okuzenzekelayo kwe-arc ukulungisa ukuwelda.

(3) Ngaphambi kokuqulunqwa, umgca uhambelana nomgangatho, ukunqunyulwa komphetho, ukucwangciswa komphetho, ukucocwa komphezulu kunye nokuhanjiswa, kunye nokunyangwa kwangaphambili.

(4) I-gauge yokudibanisa yombane isetyenziselwa ukulawula uxinzelelo lweesilinda kumacala omabini omqhubi ukuqinisekisa ukuhanjiswa okugudileyo komcu.

(5) Ukwamkela ulawulo lwangaphandle okanye ukwenziwa koluhlu lolawulo lwangaphakathi.

(6) Isixhobo sokulawula i-welding seam gap sisetyenziselwa ukuqinisekisa ukuba i-gap ye-welding seam ihlangabezana neemfuno ze-welding, kunye nobubanzi bombhobho, ubungakanani bokungahambi kakuhle kunye ne-welding seam gap zonke zilawulwa ngokungqongqo.

(7) Zombini i-welding yangaphakathi kunye ne-welding yangaphandle zamkela umatshini wokuwelda wombane we-American Lincoln we-welding ye-arc enye okanye i-double-wire submerged arc welding, ukuze ufumane iinkcukacha ezizinzileyo ze-welding.

(8) I-welded seams zonke zihlolwe nge-intanethi eqhubekayo ye-ultrasonic i-flaw isixhobo esizenzekelayo, esiqinisekisa i-100% yovavanyo olungonakalisi ukugubungela i-spiral welds.Ukuba kukho isiphene, kuya ngokuzenzekelayo i-alamu kwaye itshize uphawu, kwaye abasebenzi bemveliso banokuhlengahlengisa iiparitha zenkqubo nangaliphi na ixesha ngokutsho oku ukuphelisa isiphene ngexesha.

(9) Umatshini wokusika i-plasma yomoya usetyenziselwa ukusika umbhobho wensimbi kwiinqununu zomntu ngamnye.

10 ukuqinisekisa ukuba inkqubo yokwenza umbhobho ifanelekile.Emva koko, inokufakwa ngokusemthethweni kwimveliso.

(11) Amalungu aneempawu eziqhubekayo zokufumanisa i-sonic flaw kwi-weld ziphinda zihlolwe yi-manual ultrasonic kunye ne-X-ray.Ukuba kukho isiphene, emva kokulungiswa, kuya kuphinda kuhlolwe ngokungenakonakala kuze kube kuqinisekiswa ukuba i-defect isusiwe.

(12) Imibhobho apho umthungo wentsimbi uthungelwa ngeempundu kunye namalungu amile okwe-D anqumla imithungo ye-welding ejiyileyo yonke ihlolwa ngomabonakude weX-reyi okanye ukufotwa.

(13) Ipayipi nganye yensimbi ifumana uvavanyo loxinzelelo lwe-hydrostatic, kwaye uxinzelelo luthatha uphawu lwe-radial.Uxinzelelo lovavanyo kunye nexesha lilawulwa ngokungqongqo ngumbhobho wensimbi we-hydraulic microcomputer isixhobo sokubona.Iiparamitha zovavanyo ziprintwa ngokuzenzekelayo kwaye zirekhodwe.

(14) Isiphelo sombhobho sicutshungulwa ngoomatshini, ukwenzela ukuba ukuqina kobuso besiphelo, i-angle ye-bevel kunye ne-obtuse edge inokulawulwa ngokuchanekileyo.
