Ngelixa ubungakanani buyinto ebalulekileyo xa ukhetha iiflange, iingqiniba, kunye namanye amacandelo enkqubo yakho yokubhobhoza, iziphelo zemibhobho ziyingqwalasela ebalulekileyo ukuqinisekisa ukufaneleka okufanelekileyo, itywina eliqinileyo, kunye nokusebenza kakuhle.
Kwesi sikhokelo, siza kujonga kuqwalaselo lwesiphelo sombhobho olwahlukeneyo olukhoyo, iimeko abasoloko besetyenziswa kuzo, kunye nemiba omawuyiqwalasele xa ukhetha ukuphela kombhobho othile.
UMbhobho OQHELEKILEYO UPHELA
Uhlobo lwesiphelo sombhobho olukhethiweyo luya kugqiba ukuba ludibanisa njani namanye amacandelo kwaye zeziphi izicelo kunye namacandelo umbhobho olungele kakhulu.
Iziphelo zombhobho zidla ngokuwela kwenye yezi ndidi ezine:
- Iziphelo ezingenanto (PE)
- Iziphelo ezinemisonto (TE)
- Bevelled Ends (BW)
- Amalungu oMatshini aGrooved okanye iGrooved Ends
Umbhobho omnye unokuba neentlobo ezininzi zokuphela.Oku kudla ngokutyunjwa kwinkcazo yombhobho okanye ileyibhile.
Umzekelo, i-3/4-intshi ye-SMLS Shedyuli ye-80s A/SA312-TP316L TOE umbhobho unemisonto kwelinye icala (TOE) kwaye icacile kwelinye.
Ngokwahlukileyo, i-3/4-intshi ye-SMLS yeShedyuli ye-80s A/SA312-TP316L TBE umbhobho unemisonto kwiziphelo zombini (TBE).
ISIPHELO ESINGCACILEYO (PE) UKUSETYENZISWA KOMbhobho NOQWALASELWAYO
Imibhobho ye-PE iziphelo eziqhelekileyo zisikwe kwi-angle ye-90-degree ukuya kumbhobho oqhutywe ngeflethi, kunye nokupheliswa.
Kwiimeko ezininzi, imibhobho ecacileyo isetyenziswe ngokudibanisa ne-slip-on flanges kunye ne-socket weld fittings kunye neeflanges.
Zombini izitayile zifuna i-fillet ye-welding kulo naliphi na icala okanye omabini amacala okulingana okanye i-flange kunye nesiseko se-fitting okanye i-flange.
Apho kufanelekileyo, isiphelo sethafa siya kubekwa ngokwesiqhelo ⅛” ukusuka apho umbhobho uphumle khona ukuvumela ukwandiswa kwe-thermal ngexesha le-welding.
Oku kubenza balungele iinkqubo ezincinci zemibhobho edayamitha encinci.
ISIPHELO ESINOMICHUVA (TE) UKUSETYENZISWA KWAKUNYE NOQWALASELWEYO
Ngokuqhelekileyo isetyenziselwa imibhobho enobungakanani obuncinci bee-intshi ezintathu okanye ezincinci, imibhobho ye-TE ivumela itywina eligqwesileyo.
Uninzi lwemibhobho zisebenzisa i-National Pipe Thread (NPT) umgangatho ochaza iintambo ezinqamlekileyo ezisetyenziswe kumbhobho kunye neyona taper eqhelekileyo yokulinganisa i-3/4-intshi ngeenyawo.
Le taper ivumela iintambo ukuba zitsale ngokuqinileyo kwaye zenze itywina elisebenzayo ngakumbi.
Nangona kunjalo, ukudibanisa imicu kumbhobho we-TE ngokufanelekileyo kubalulekile ukuphepha ukulimaza imibhobho, izixhobo, okanye iiflange.
Ukudityaniswa okungafanelekanga okanye ukuchithwa kungakhokelela ekuqhumeni okanye ekuhluthweni.
Emva kokuba ingasetyenziswanga, umonakalo kwimicu okanye umbhobho unokunciphisa ngakumbi ukuxhatshazwa kwe-corrosion kunye neempawu zokucoceka - izizathu ezibini ezithandwayo zokukhetha umbhobho wensimbi engenasici.
Ngethamsanqa, ukunqanda ezi nkxalabo kuhlala kulula njengokulungisa imisonto phambi kokuhlanganisa.
Sincoma kwaye sithengise i-tape ye-Unasco yensimbi engenasici yokutywina.
Ifakwe nge-nickel powder, iteyiphu igcina ubuso bomsonto wendoda kunye nowasetyhini uphela ngokwahlukeneyo ngelixa uthambisa umdibaniso ukuze kube lula ukuhlanganisa kunye nokuqhawula.
I-BEVELLED END (BW) UKUSETYENZISWA KWE-PIPE KUNYE NEINGQWELO
Isetyenziswa kunye ne-buttwelding, izifakelo zemibhobho ye-BW zihlala zine-bevel ye-37.5-degree.
Ezi bevels zihlala zisetyenziswa ngabavelisi ngesandla okanye ngeenkqubo ezizenzekelayo zokuqinisekisa ukuhambelana.
Oku kuvumela umdlalo ogqibeleleyo kunye nokufakwa kombhobho we-BW kunye neeflange kunye nokuwelda lula.
UKUSETYENZISWA KOMbhobho WOKUPHELA KWAYE KUQWALASELWE
Amalungu omatshini adibeneyo okanye imibhobho yokuphela kwe-grooved isebenzisa i-groove eyenziwe okanye eyenziwe ngomatshini ekupheleni kombhobho ukuze ihlale i-gasket.
Indlu ejikeleze i-gasket iye yaqiniswa ukukhusela uqhagamshelo kunye nokuqinisekisa ukutywinwa kunye nokusebenza kakuhle.
Uyilo luvumela ukuchithwa lula kunye nomngcipheko oncitshisiweyo wokonakalisa amacandelo emibhobho.
UMbhobho OQHELEKILEYO UPHELA USHWANKATHELO NEMIGANGATHO
Uqhagamshelo lombhobho oludla ngokusetyenziswa kwiingono zemibhobho - zidla ngokuchazwa kusetyenziswa izishunqulelo.
Kwiimeko ezininzi, unobumba wokuqala uchaza uhlobo lwesiphelo esisetyenzisiweyo ngelixa oonobumba balandelayo bekwazisa ukuba zeziphi iziphelo ezigqityiweyo.
Izishunqulelo eziqhelekileyo ziquka:
- YIBA:Bevel End
- BBE:Bevel Zombini Iziphelo
- BLE:Bevel Enkulu End
- BOE:Bevel One End
- BSE:Bevel Small End
- BW:Buttweld End
- PE:Isiphelo esicacileyo
- PBE:Plain Zombini Iziphelo
- POE:Isiphelo esinye esicacileyo
- TE:Ukuphela komsonto
- TBE:Umsonto kwiziphelo zombini
- TLE:Umsonto Isiphelo Esikhulu
- ULWAZI:Umsonto Omnye Ukuphela
- TSE:Isiphelo Esincinci Somsonto
