Ingcaciso yeMveliso

Imibhobho yentsimbi ye-Spiral, ekwabizwa ngokuba yi-helical submerged arc-welded (HSAW) imibhobho, luhlobo lombhobho wentsimbi ophawulwa ngenkqubo yawo yokwenziwa eyahlukileyo kunye neempawu zesakhiwo.Le mibhobho isetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yamandla ayo, ukuqina, kunye nokuguquguquka.Nantsi inkcazo eneenkcukacha yemibhobho yentsimbi ejikelezayo:

Inkqubo yokuVelisa:Imibhobho yentsimbi ye-Spiral iveliswa ngenkqubo eyodwa ebandakanya ukusetyenziswa kwekhoyili yomgca wentsimbi.Umcu awunakwenzakala kwaye wenze imilo ejikelezayo, emva koko udityaniswe kusetyenziswa ubuchule be-arc welding ephantsi kwamanzi (SAW).Le nkqubo iphumela ekuqhubekeni, i-helical seam kunye nobude bombhobho.

Uyilo loLwakhiwo:Umthungo we-helical wemibhobho yensimbi ejikelezayo inika amandla angokwemvelo, okwenza ukuba ifanelekele ukujamelana nemithwalo ephezulu kunye noxinzelelo.Olu yilo luqinisekisa ukusabalalisa okufanayo koxinzelelo kunye nokwandisa amandla ombhobho ukuxhathisa ukugoba kunye nokuguqulwa.

Uluhlu lobungakanani:Imibhobho yentsimbi ye-Spiral iza kuluhlu olubanzi lweedayamitha (ukuya kwi-120 Intshi) kunye nobukhulu, okuvumela ukuguquguquka kwizicelo ezahlukeneyo.Ngokuqhelekileyo zifumaneka kwiidamitha ezinkulu xa kuthelekiswa nezinye iintlobo zemibhobho.

Usetyenziso:Imibhobho yentsimbi ye-Spiral isetyenziswa kumashishini ahlukeneyo afana ne-oyile negesi, unikezelo lwamanzi, ulwakhiwo, ezolimo, kunye nophuhliso lwezakhiwo.Ziyafaneleka kuzo zombini izicelo ezingaphezulu komhlaba naphantsi komhlaba.

Ukuxhathisa ukonakala:Ukomeleza ubomi obude, imibhobho yentsimbi ejikelezayo isoloko ifumana unyango lokulwa nokubola.Ezi zingabandakanya iingubo zangaphakathi nangaphandle, ezifana ne-epoxy, i-polyethylene, kunye ne-zinc, ekhusela imibhobho kwizinto ezisingqongileyo kunye nezinto ezitshabalalisayo.

Izinto eziluncedo:Imibhobho yentsimbi ye-Spiral inika iingenelo ezininzi, kubandakanywa umthamo ophezulu wokuthwala umthwalo, ukuphumelela kweendleko kwimibhobho yobubanzi obukhulu, ukufakwa lula, kunye nokuchasana nokuguqulwa.Uyilo lwazo lwe-helical lukwanceda ekukhupheni amanzi ngokufanelekileyo.

Ixesha elideVSI-Spiral:Imibhobho yentsimbi ye-Spiral iyahlukaniswa kwimibhobho edityaniswe ngobude ngokwenkqubo yokwenziwa kwayo.Ngelixa imibhobho ye-longitudinal yenziwe kwaye idityaniswe kunye nobude bombhobho, imibhobho ejikelezayo inomthungo we-helical owenziwe ngexesha lokuvelisa.

Ulawulo lwemeko:Uveliso kunye neenkqubo zokulawula umgangatho zibalulekile ekuveliseni imibhobho yentsimbi ejikelezayo ethembekileyo.Iiparamitha ze-Welding, ijometri yombhobho, kunye neendlela zokuvavanya zijongwa ngononophelo ukuze kuqinisekiswe ukuthotyelwa kwemigangatho yoshishino kunye neenkcukacha.

Imigangatho kunye neNgcaciso:Imibhobho yentsimbi ye-Spiral yenziwa ngokuhambelana nemigangatho yezizwe ngezizwe kunye neshishini elithile njenge-API 5L, ASTM, EN, kunye nabanye.Le migangatho ichaza iipropati eziphathekayo, iindlela zokuvelisa, kunye neemfuno zokuvavanya.

Isishwankathelo, iibhobho zensimbi ezijikelezayo zisisombululo esiguquguqukayo kunye nesigxina kumashishini ahlukeneyo.Inkqubo yabo yokuvelisa eyodwa, amandla endalo, kunye nokufumaneka kobukhulu obahlukeneyo kunegalelo ekusetyenzisweni kwabo ngokubanzi kwiziseko zophuhliso, ezothutho, amandla, ukwakhiwa kwezibuko nokunye.Ukhetho olufanelekileyo, ulawulo lomgangatho, kunye nemilinganiselo yokukhusela i-corrosion idlala indima ebalulekileyo ekuqinisekiseni ukusebenza kwexesha elide lemibhobho yentsimbi ejikelezayo.

Ukusetyenziswa kunye nesicelo

Imibhobho yentsimbi ye-Spiral iguquguquka kwaye isetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yeempawu zabo ezizodwa kunye neenzuzo.Ziyilwa ngokudibanisa imicu yentsimbi kunye ukwenza umbhobho onomthungo ojikelezayo.Nazi ezinye izicelo eziqhelekileyo zemibhobho yentsimbi ejikelezayo:

● UThutho lolwelo: Le mibhobho iwahambisa kakuhle amanzi, ioyile, nerhasi ukunqumla imigama emide kwimibhobho ngenxa yolwakhiwo olungenamithungo namandla ayo aphezulu.
● Ioli NeGesi: Ibalulekile kwimizi-mveliso yeoli nerhasi, ithutha ioli ekrwada, igesi yendalo, nezinto ezisulungekisiweyo, ezinceda ekuhlolweni nasekuhanjisweni kwazo.
● Ukufakwa kwemfumba: Iimfumba ezisisiseko kwiiprojekthi zokwakha zixhasa imithwalo enzima kwizakhiwo ezifana nezakhiwo neebhulorho.
● Ukusetyenziswa Kwesakhiwo: Xa zisetyenziswa kwiziseko zokwakha, iintsika kunye nezixhaso, ukuqina kwazo kufak' isandla kuzinzo lwesakhiwo.
● I-Culverts kunye ne-Drainage: Isetyenziswe kwiinkqubo zamanzi, ukuxhathisa ukubola kunye ne-interiors egudileyo ikhusela ukuvala kunye nokuphucula ukuhamba kwamanzi.
● IiTubhili zoomatshini: Kwimveliso kunye nezolimo, le mibhobho ibonelela ngezisombululo ezingabizi kakhulu, ezomeleleyo kumacandelo.
● Ezaselwandle kunye ne-Offshore: Kwimekobume erhabaxa, isetyenziswa kwimibhobho engaphantsi kwamanzi, amaqonga akude nonxweme, kunye nolwakhiwo lweenqanawa.
● Ukwembiwa kwemigodi: Bahambisa imathiriyeli kunye nodaka kwimisebenzi yemigodi efuna ngamandla ngenxa yolwakhiwo oluqinileyo.
● Ubonelelo lwaManzi: Ilungele imibhobho yobubanzi obukhulu kwiinkqubo zamanzi, ukuthutha ngokufanelekileyo umthamo wamanzi abalulekileyo.
● IiNkqubo zeGeothermal: Zisetyenziswa kwiiprojekthi zamandla e-geothermal, zijongana nokuhanjiswa kolwelo olukwaziyo ukumelana nobushushu phakathi kwamadama kunye nezixhobo zombane.

Ubume obuguquguqukayo bemibhobho yentsimbi ejikelezayo, edityaniswe namandla ayo, ukuqina, kunye nokuguquguquka, ibenza ibe yinxalenye ebalulekileyo kuluhlu olubanzi lwamashishini kunye nokusetyenziswa.

Ukupakisha kunye nokuThumela

Ukupakisha:
Inkqubo yokupakisha imibhobho yentsimbi ejikelezayo ibandakanya amanyathelo aphambili aliqela ukuqinisekisa ukuba imibhobho ikhuselwe ngokwaneleyo ngexesha lothutho nokugcinwa:
● Ukudityaniswa kwemibhobho: Imibhobho yentsimbi engqukuva idla ngokudityaniswa kusetyenziswa amaqhina, amaqhina entsimbi, okanye ezinye iindlela zokubopha ezikhuselekileyo.Ukudibanisa kuthintela imibhobho nganye ukuba ihambe okanye itshintshe ngaphakathi kokupakishwa.
● Ukukhuselwa koMbhobho wokuPhepha: Iiplastiki zeplastiki okanye izikhuselo ezikhuselayo zifakwe kwiiphelo zombini zemibhobho ukukhusela umonakalo kwiiphelo zombhobho kunye nomgangatho wangaphakathi.
● Ukuthintela amanzi: Imibhobho isongelwe ngezinto ezingangeni manzi, njengeplastiki okanye ukusongelwa, ukuze ikhuseleke kubumanzi xa ithuthwa, ngokukodwa xa ithunyelwa ngaphandle okanye elwandle.
● Ukufakwa kwezingxobo: Izinto ezongezelelekileyo zokugquma, ezifana nezifakelo ezinogwebu okanye izinto zokuthambisa, zinokudityaniswa phakathi kwemibhobho okanye kwiindawo ezibuthathaka ukuze kufunxe ukothuka kunye nokungcangcazela.
● Ukufaka iilebhile: Inyanda nganye ibhalwe ngolwazi olubalulekileyo, kuquka neenkcukacha zombhobho, imilinganiselo, ubungakanani, kunye nendawo ekuyiwa kuyo.Oku kunceda ekuchongeni nasekuphatheni lula.

Ukuhambisa ngenqanawe:
● Ukuthumela imibhobho yentsimbi ejikelezayo kufuna ukucwangciswa ngenyameko ukuze kuqinisekiswe uthutho olukhuselekileyo nolusebenzayo:
● Indlela yezoThutho: Ukhetho lwendlela yothutho (indlela, uloliwe, ulwandle, okanye umoya) luxhomekeke kwizinto ezifana nomgama, ungxamiseko, kunye nokufikeleleka kwendawo.
● Ukufakwa kwizikhongozeli: Imibhobho inokulayishwa kwizikhongozeli zokuhambisa ezisemgangathweni okanye kwizikhongozeli ezikhethekileyo ezisicaba.I-Containerization ikhusela imibhobho kwizinto zangaphandle kwaye inika indawo elawulwayo.
● Ukukhusela: Imibhobho ibotshelelwa kwizikhongozeli kusetyenziswa iindlela ezifanelekileyo zokuyibopha, njengokuyiqinisa, ukuyivalela, nokuqhwatywa.Oku kuthintela ukunyakaza kunye nokunciphisa umngcipheko womonakalo ngexesha lokuhamba.
● Amaxwebhu: Amaxwebhu achanekileyo, kuquka ii-invoyisi, uludwe lokupakisha, kunye nemanifefethi yokuthumela ngenqanawa, alungiselelwa ukukhutshwa kwempahla neenjongo zokulandelela umkhondo.
● I-inshorensi: I-inshorensi yempahla idla ngokufunyanwa ukuze kuhlawulelwe ilahleko okanye umonakalo osenokubakho ebudeni bohambo.
● Ukubeka iliso: Kuyo yonke inkqubo yokuthumela, iipayipi zinokulandelwa ngokusebenzisa i-GPS kunye neenkqubo zokulandelela ukuze kuqinisekiswe ukuba zihamba ngendlela efanelekileyo kunye neshedyuli.
● UCwangciso lweRhafu yoRhwebo: Amaxwebhu afanelekileyo anikezelwe ukuququzelela ukukhutshwa ngokutyibilikayo kwizibuko okanye kumda.

Isiphelo:
Ukupakishwa ngokufanelekileyo kunye nokuthunyelwa kweepayipi zensimbi ezijikelezayo zibalulekile ukugcina umgangatho wemibhobho kunye nokunyaniseka ngexesha lokuthutha.Ukulandela iindlela ezingcono zoshishino kuqinisekisa ukuba imibhobho ifikelela kwindawo yayo ikwimeko efanelekileyo, ilungele ukufakela okanye ukuqhubekeka phambili.
