Yazisa:
Kwilizwe lentsimbi yentsimbi,I-Spiral Deped Pipeithandwa ngamandla ayo aphezulu, ngokutshintshana kunye nokusebenza kweendleko. Le mibhobho isetyenziswa ngokubanzi kumashishini ahlukeneyo anjengeoyile kunye negesi, ukuhambisa amanzi, ubunjineli bamanzi kunye nophuhliso lwezibonelelo. Ukuqinisekisa ukudityaniswa okungenamthungo kunye nokusebenza ngokugqibeleleyo, kubalulekile ukuba uqonde imigaqo-nkqubo elawula imibhobho ye-whidi. Kwezi bhlog, siya kuqhuba kwimiba ephambili yemibhobho ye-Pemiral ye-Spils, ecacisa imilinganiselo yabo, izixhobo kunye neemfuno ezithile.
1. Ubungakanani bombhobho:
Imibhobho ye-Welfled Welding ifumaneka kubungakanani beentlobo, ukuqinisekisa ukuhambelana neeprojekthi ezahlukeneyo. Imilinganiselo eqhelekileyo ibandakanya ububanzi bobubanzi (i-OD), ubukhulu bomhlaba (i-WT), kunye nobude. I-Diameter engaphandle isuka kwi-intshi ezingama-20 ukuya kwi-intshi ezili-120, kunye nobubanzi beWall busuka kwi-5 mm ukuya kwi-25 mm. Ngokwemde, amacandelo aqhelekileyo aqhelekileyo emibhobho ye-welfrals ye-spils ziimitha ezi-6, iimitha ezisi-8, kunye neemitha ezili-12 zokuziqhelanisa neemfuno zobunjineli ezahlukeneyo.
2. Izixhobo:
Ukhetho lwemibhobho ye-SSAW ibalulekile kwaye ixhomekeke ikakhulu kwisicelo esicetywayo kunye neemeko zokusingqongileyo. I-Carbon Steel isetyenziselwa amandla ayo, ukuqina, kunye nokunganyangeki. Ukongeza, kwizicelo ezithile ezifuna ukumelana nokunganyangeki okuphuculweyo okanye ukuxhathisa kobushushu obuphezulu, imibhobho eyenziwe ngentsimbi, intsimbi engenasitali, okanye ezinye izinto ezizodwa ezinokusetyenziswa.
I-3. Inkqubo yokuvelisa:
I-Spiral Deling Peped iveliswa ngenkqubo yokwakha i-spirals eqhubekayo isebenzisa amakhoyitha yentsimbi. Le ndlela iqinisekisa ukungalingani kobunzima obungasell, ububanzi kunye nengqibelelo yendlela epheleleyo. I-coil ityalwe kumatshini, nto leyo eyayifaka kwimilo enqwenelekayo yeSPIRAL kwaye ihlambe kunye. Iitekhnoloji eziphambili ezichaphazelekayo kwinkqubo yokwenziwa ivumela ulawulo oluchanekileyo ngaphezulu kobungakanani kunye nokusebenza kombhobho wokugqibela.
4. Imigangatho esemgangathweni:
Ukuhlangabezana nemigangatho yemizi-mveliso kunye nokuqinisekisa ukuthembeka kwemibhobho ye-spils, iindlela zokuqinisekisa umgangatho. Oku kubandakanya ukuthotyelwa kwemigangatho eyamkelweyo yamazwe aphesheya njenge-API 5L, i-ASTM A252 kunye ne-ISO 3183-3. Ukuthotyelwa kwezi ngxelo ziqinisekisa iipropathi zoomatshini, ubume bezikhemikhali, kunye nokuchaneka kombhobho wombhobho.
5. Uvavanyo kunye nokuhlolwa:
Ukuqinisekisa ukuthembeka kunye nokusebenza okukhuselekileyo kombhobho we-spil welding, uvavanyo olungqongqo kunye neenkqubo zokuhlola ziyafuneka. Sebenzisa iindlela zokuhlola ezizonke ezonakalisayo ezinje ngovavanyo lwe-Ultrasonic, uvavanyo lwe-radiographic kunye novavanyo lombala. Olu vavanyo luchonge zonke iimpazamo zezakhiwo okanye ukungangqinelani kwezinto ezinokuthi kuchaphazele intsebenzo kunye nokuqina kombhobho. Ukongeza, iimvavanyo zomzimba ezinjengokuvavanywa kwe-hydrostatic zenziwa ukuvavanya amandla kunye nokuthwala uxinzelelo lwemibhobho.
Ukuququmbela:
Imibhobho ye-Willic ye-Weldied inika izibonelelo ezininzi ngaphezulu kwezinye iintlobo zepayi kunye neenkcazo zazo zidlala indima ebalulekileyo ekugcineni umgangatho wabo, ukuthembeka kunye nokuhambelana nezicelo ezahlukeneyo. Ukuqonda ubungakanani, izixhobo, iinkqubo zemveliso kunye nemigangatho esemgangathweni enxulumene nombhobho we-welfral wels ebaluleke kakhulu ekuqinisekiseni intsebenzo efanelekileyo kunye nesisombululo esisebenzayo. Njengoko itekhnoloji iyaqhubeka ukuqhubela phambili, iinkcazo ezilawula imibhobho ziyaqhubeka nokuphucula, ukuphucula ukusebenza kwazo kunye nokungahambi kakuhle kumashishini ahlukeneyo. Ngokuqwalasela ezi ngcaciso, iinjineli kunye neengcali zinokwenza izigqibo ezinolwazi malunga nokukhethwa kunye nokusetyenziswa kombhobho we-spild ye-spils yeeprojekthi zabo.
