I-Spiral Deeld Piped Ping ye-Piper yeNdalo engaphantsi komhlaba
Yazisa:
Phantsi kwemibhobho yegesi yendalo idlala indima ebalulekileyo ekunikezeleni lo msebenzi uxabisekileyo kumakhaya, amashishini kunye nomzi mveliso. Ukuqinisekisa ukhuseleko kunye nokusebenza kakuhle kwale mibhobho, kubalulekile ukusebenzisa izixhobo ezichanekileyo kunye neenkqubo ze-welding ngexesha lokwakha. Siza kuphonononga ukubaluleka kombhobho wentsimbi ye-spil welding kunye nokubaluleka kweenkqubo ezifanelekileyo zefelding xa usebenza ngePhantsi kombhobho wegesi yendalo.
Imibhobho ye-Welding Welding:
Imibhobho ye-Welding ye-Welding ithandwayo ekwakhiweni kwemibhobho yegesi yendalo engaphantsi komhlaba ngenxa yamandla ayo kunye nokuqina. Le mibhobho yenziwa ngokugoba intsimbi eqhubekayo yentsimbi ibe yimo ye-spiral kwaye emva koko yayiyityalela emigqomeni. Isiphumo yimibhobho ngamalungu aqinileyo, atywinwa anokujamelana noxinzelelo lwangaphandle olubalulekileyo kwaye alungelelanise iintshukumo zomhlaba. Esi sakhiwo sahlukileyo senzaI-Spil Deeld Pipe PipeIlungele imibhobho engaphantsi komhlaba apho uzinzo lubalulekile.

Uvavanyo lwe-hydrostatic
Ubude bombhobho buya kuvavanywa ngumenzi kwingcinezelo ye-hydrostatic eya kuthi ivelise udonga lombhobho woxinzelelo olungaphantsi kwe-60% yamandla egumbi elichaziweyo kubushushu begumbi. Ingcinezelo iya kugqitywa ngale quation ilandelayo:
P = 2st / d
Umahluko ovumelekileyo kwimilinganiselo kunye nobungakanani
Ubude bombhobho buya kuba bunzima ngokwahlukeneyo kwaye ubunzima bayo abuyi kudliwa ngaphezulu kwe-10% ngaphezulu okanye i-5.5% phantsi komzimba wayo, ukubalwa kusetyenziswa ubude bayo.
Ububanzi bangaphandle abuyi kwahluka ngaphezu kwe- ± 1% ukusuka kwibala elichaziweyo langaphandle.
Ubunzima bodonga nangayiphi na inqaku aliyi kuba ngaphezulu kwe-12,5% phantsi kobunzima obuchaziweyo.
Ubude
Ubude obungakhethwanga okanye i-16 ukuya kwi-25ft (4.88 ukuya kwi-7.62m)
Ubude obuPhindwe kabini: Ngaphezulu kwe-35ft ukuya kwi-35ft (7.62 ukuya kwi-10.67m)
Ubude be-iyunifomu: ukwahluka okwaneleyo ± 1in
Iphela
Imfumba yepayiwe iya kugcinwa ngobutyebi ecacileyo, kwaye iifayili eziphelweni ziya kususwa
Xa umbhobho wokuphela echazwe ukuba i-Bevel iphela, i-engile iya kuba ngama-30 ukuya kwi-35 degree
IINKQUBO ZE-PAIM
KufanelekileInkqubo ye-welding ye-Pelingzibalulekile ekuzinqeni nasekukhuselekeni kwemibhobho yegesi yendalo engaphantsi komhlaba. Nazi izinto ezimbalwa ezibalulekileyo ekufuneka ziqwalaselwe:
1. Iziqinisekiso ze-Welder:Abenzi abanamava nabanamava kufuneka baqeshiwe, qinisekisa ukuba banolwazi oluyimfuneko kunye nobuchule bokujongana neenkqubo ezithile ze-welding ezifunekayo kwimibhobho yegesi yendalo. Oku kunceda ukunciphisa umngcipheko wesiphene se-welding kunye nokuvuza okunokwenzeka.
2. Ukulungiswa ngokudibeneyo kunye nokucoca:Ukulungiswa ngokudibeneyo kubalulekile ngaphambi kokuba kwelding. Oku kubandakanya ukususa naluphi na ubumdaka, ubugebenga okanye ubugqwetha obunokuchaphazela kakubi ingqibelelo ye-shld. Ukongeza, inkansa imiphetha yombhobho inceda ukudala i-Welded eyomeleleyo.
I-3. Iindlela ze-welding kunye neeparamitha:Iindlela ezifanelekileyo ze-welding kunye neeparamitha kufuneka zilandelwe ukufumana i-werds ekumgangatho ophezulu. Inkqubo ye-welding kufuneka ithathele ingqalelo izinto ezinje ngombhobho wobunzima, indawo ye-welding, ukwenziwa kwe-welding, njl. Njl.
4. Uvavanyo kunye novavanyo:Ukuhlolwa ngokuchanekileyo kunye nokuvavanywa kwe-WOTT kubalulekile ukuqinisekisa umgangatho wayo kunye nengqibelelo. Itekhnoloji efana novavanyo olungelulo uqhekekayo (i-NDT), kubandakanya i-X-ray okanye uvavanyo lwe-Ultrasonic, linokufumana nasiphi na isiphene esinokubakho esinokuthi sityeshele ukuthembeka kwexesha elide lombhobho.
Ukuququmbela:
Ukwakhiwa kwemibhobho yegesi yendalo engaphantsi komhlaba usebenzisa imibhobho yentsimbi ye-Welfd ye-Weld ifuna ukuthotyelwa kweenkqubo ezifanelekileyo ze-weldiy. Ngokuqesha abaphikisi abafanelekileyo, belungiselela ngononophelo, kwaye bafumana uhlolo olufanelekileyo, sinokuqinisekisa ukhuseleko, ukuqina, kunye nokusebenza kakuhle kwale mibhobho. Ngokuqwalasela ngononophelo kwiinkcukacha kwinkqubo ye-welding, singayihambisa ngokuzithemba irhasi yendalo ukuhlangabezana neemfuno zamandla kwiindawo zethu zoluntu xa zibeka phambili intlalo-ntle yokusingqongileyo kunye nokhuseleko loluntu.
