Ukuhlolwa kweFlange Fasteners

Ukuhlolwa kweefasteners zeflange yinxalenye ebalulekileyo yokugcina ingqibelelo kunye nokhuseleko lweenkqubo zemibhobho, iinqanawa zoxinzelelo, kunye nezinye izixhobo zoshishino. Iiflange zisetyenziselwa ukudibanisa imibhobho, iivalve, kunye namanye amacandelo, kunye nezibophelelo (iibholiti kunye namantongomane) ezikhuselayo kufuneka zibekwimeko elungileyo ukuqinisekisa uqhagamshelo olungavuziyo nolukhuselekileyo. Nantsi eminye imiba ephambili ekufuneka uyiqwalasele xa uhlola iziqhoboshi zeflange:

1. UHlolo oluBonakalayo:

•Jonga iimpawu zomhlwa, umngxuma, okanye umhlwa kwiibholithi kunye namandongomane.

•Jonga iintanda okanye iifracture.

•Hlola ukuguqulwa, njengokuzolula okanye ukugoba.

•Qinisekisa ukuba akukho monakalo kwimisonto.

•Qinisekisa ukuba zonke iziqhoboshi zikhona kwaye akukho nanye ilahlekileyo.

2. Ukuqina kunye neTorque:

•Qinisekisa ukuba i-fasteners igxininiswe kwi-torque echaziweyo. Ukuqiniswa kakhulu kunokubangela umonakalo, ngelixa ukuqiniswa ngaphantsi kunokukhokelela ekuvuzeni.

•Sebenzisa i-torque wrench yokulinganisa ukujonga kunye nokulungelelanisa i-torque ukuba kuyimfuneko.

•Landela izikhokelo zomenzi okanye imigangatho yoshishino ngolandelelwano oluchanekileyo lokuqinisa kunye namaxabiso etorque.

3. Ulungelelwaniso:

•Qinisekisa iiiflangezilungelelaniswe ngokufanelekileyo. Ukungalungelelani kakuhle kunokubeka uxinzelelo olungalinganiyo kwiifasteners, ezikhokelela ekungaphumelelini kwangaphambi kwexesha.

•Khangela ukuba i-gasket ixinzelelwe ngokulinganayo kwaye ayiphumeli emacaleni.

4. Ukuthambisa:

•Ukuba kuyasebenza oku, qinisekisa ukuba iziqhoboshi zifakwe i-lubriberi ngokweenkcukacha. I-lubrication efanelekileyo inokunceda ukukhusela ukubamba kunye nokwenza kube lula ukufezekisa i-torque echanekileyo.

5. Imeko yeGasket:

•Nangona ingeyiyo i-fastener, i-gasket yinxalenye ebalulekileyo yejoint flanged. Jonga i-gasket ngomonakalo, ukusikwa, okanye iimpawu zokuwohloka.

•Qinisekisa ukuba i-gasket luhlobo oluchanekileyo kunye nobukhulu besicelo.

6. Ukuhambelana kwezinto:

•Qinisekisa ukuba izinto zokubopha ziyahambelana neemeko zenkonzo, kubandakanywa ubushushu, uxinzelelo, kunye nendawo ephathwayo.

•Khangela nayiphi na imiqondiso ye-galvanic corrosion, enokuthi yenzeke xa izinyithi ezingafaniyo zidibanisa phambi kwe-electrolyte.

7. Ukumakishwa kunye namaxwebhu:

•Qinisekisa ukuba iziqhoboshi zineempawu ezifanelekileyo zokuchonga amabakala azo kunye nemathiriyeli.

•Gcina iirekhodi zohlolo, kubandakanywa naziphi na izinto ezifunyenweyo, izenzo ezithathiweyo, kunye nomhla wokuhlolwa okucwangcisiweyo okulandelayo.

8. UVavanyo olungangonakalisiyo (NDT):

•Kwezinye iimeko, iindlela zovavanyo ezingonakalisi ezifana nokuhlolwa kwemagnethi (MPI), ukuhlolwa kwe-liquid penetrant inspection (LPI), okanye uvavanyo lwe-ultrasonic (UT) kunokufuneka ukuba kubonwe iziphene zangaphakathi ezingabonakali ngexesha lokuhlolwa okubonakalayo.

9. ULondolozo lwarhoqo:

•Ukuseka ishedyuli yokugcinwa rhoqo yokuhlola kwakhona kunye nokuqinisa kwakhona izibophelelo, njengoko kufunwa yimiqathango yokusebenza kunye neengcebiso zomenzi.

Kubalulekile ukulandela iikhowudi ezifanelekileyo kunye nemigangatho, efana ne-ASME B16.5 yeeflange zemibhobho kunye nokufakwa kwe-flanged, kunye ne-API 6A ye-wellhead kunye nezixhobo zomthi weKrisimesi, xa usenza uhlolo. Ngalo lonke ixesha qinisekisa ukuba abasebenzi abenza uhlolo baqeqeshiwe kwaye bakulungele ukwenza oko.
