Kulwakhiwo lwemibhobho yegesi yendalo, ukhetho lwezinto eziphathekayo kunye neenkqubo ze-welding zibalulekile ekuqinisekiseni ukhuseleko nokusebenza kakuhle. I-SSAW (i-Spiral Submerged Arc Welded) ipayipi yensimbi yenye yezona zinto zisetyenziswa ngokuqhelekileyo kweli shishini. Kule ngxelo yeblogi, siza kuhlolisisa ukubaluleka kweenkqubo zokuwelda ezifanelekileyo zokufakelwa kombhobho wegesi yendalo usebenzisa umbhobho wensimbi we-SSAW kunye nokubonelela ngesikhokelo esisisiseko sokuqonda le nxalenye ebalulekileyo yokwakhiwa kwemibhobho.
Yintoni i-SSAW Steel Pipe?
Umbhobho wentsimbi we-SSAWwenziwa ngemicu yentsimbi edityanisiweyo ne-spiral ukuvelisa umbhobho oqinileyo, oqinileyo wobubanzi obukhulu. Olu hlobo lombhobho luthandwa kakhulu kumashishini egesi kunye neoli ngenxa yokuchasana noxinzelelo oluphezulu kunye nokubola. Inkqubo yokwenziwa kwayo isebenzisa i-arc welding ephantsi kwamanzi, evelisa i-welds ecocekileyo kwaye eyomeleleyo, eyenza ibe yinto efanelekileyo kwizicelo ezibalulekileyo ezifana nemibhobho yegesi yendalo.
Ukubaluleka kweeNkqubo zeWelding efanelekileyo
I-Welding linyathelo elibalulekileyo kwinkqubo yokufakela umbhobho wegesi yendalo, kwaye umgangatho we-weld unokuchaphazela kakhulu ingqibelelo yonke yombhobho. Iinkqubo zokuwelda ezichanekileyo ziyimfuneko ukuze kuqinisekiswe ukuba i-SSAW izidibanisi zemibhobho yentsimbi yomelele kwaye ayinakuvuza. Nazi ezinye izinto eziphambili ekufuneka ziqwalaselwe xa udityaniswa umbhobho wentsimbi we-SSAW kwimibhobho yerhasi yendalo:
1. I-Welding Technique: Ukukhethwa kobuchule be-welding buchaphazela umgangatho we-weld. Ngokuxhomekeke kwiimfuno ezithile zeprojekthi, iindlela ezifana ne-TIG (i-Tungsten Inert Gas) okanye i-MIG (i-Metal Inert Gas) ingasetyenziswa. Ubuchule ngabunye buneenzuzo kunye nokungalungi, kwaye ukukhetha ubuchule obufanelekileyo kubalulekile ukufezekisa ibhondi eyomeleleyo.
2. Ukulungiswa kwezinto: Ngaphambi kwe-welding, umphezulu we-spiral submerged arc welded steel pipe kufuneka ulungiswe. Oku kubandakanya ukucoca umphezulu kunye nokususa nayiphi na into engcolileyo enokuthi yenze buthathaka i-weld, njenge-rust, ioli okanye ukungcola. Ukongeza, umbhobho kufuneka ulungelelaniswe ngokufanelekileyo ukuze uqinisekise i-weld elinganayo.
3. Iiparamitha ze-Welding: Izinto ezifana nesantya se-welding, i-voltage kunye ne-current kufuneka ilawulwe ngononophelo ngexeshaumbhobho wentsimbi wokuwelda. Ezi parameters zichaphazela igalelo lobushushu kunye nezinga lokupholisa, nto leyo echaphazela iimpawu zomatshini we-weld.
4. Ukuhlolwa kwe-post-weld: Emva kwe-welding, kufuneka kuhlolwe ngokucokisekileyo ukuze kubonwe naziphi na iziphene okanye izixhumanisi ezibuthathaka kwi-weld. Iindlela zokuvavanya ezingonakalisi ezifana novavanyo lwe-ultrasonic okanye uvavanyo lwe-radiographic zingasetyenziselwa ukuqinisekisa ukuthembeka kwe-weld.
Ukuzibophelela kwethu kuMgangatho
Ifumaneka eCangzhou, kwiPhondo leHebei, inkampani ibe yinkokeli kushishino lokuvelisa umbhobho wentsimbi ukususela ngo-1993. Le nkampani igubungela indawo ye-350,000 square metres, ine-asethi epheleleyo ye-RMB 680 yezigidi, kwaye inamagcisa angama-680 azinikele ekuveliseni umgangatho ophezulu we-spiral submerged arc welded steel pipes. Amava ethu atyebileyo kunye nezixhobo eziphucukileyo zisenza sikwazi ukuhlangabezana neemfuno ezingqongqo zoshishino lombhobho werhasi yendalo.
