Kubanini bezikhululo zepetroli kunye nabaqhubi, izixhobo zemibhobho kunye neenkqubo zokufaka amafutha ezisekelwe kwi-fiberglass okwangoku kunzima ukuzifumana ngenxa yokunqongophala kwe-resin, okwenza kube nzima ukufumana ukufakelwa kwetyhubhu yomoya (UST) kwiitanki zokugcina ezingaphantsi komhlaba. Oku kunqongophala kuthintela ukufakwa kweenkqubo ezintsha okanye eziphuculweyo, njengoko umbane uyinto efunekayo ekufakelweni kwepetroli njengoko uhamba ukusuka kwi-UST ukuya kwi-vacuum exhaust yoxinzelelo lwenkqubo.
Umgca womoya ubalulekile ekusebenzeni kwenkqubo ye-UST njengoko ivumela itanki ukuba ikhuphe umoya xa uxinzelelo lwayo lwangaphakathi okanye i-vacuum idlula inqanaba elithile, nto leyo evumela itanki ukuba "iphefumle". Nangona ukunqongophala kwefiberglass ngokungathandabuzekiyo kuyingxaki, kukho isisombululo esingaqhelekanga nesiqinisekisiweyo: imibhobho yomoya eguquguqukayo.
Iipayipi zomoya ezingenangxaki I-OPW inikezela uluhlu olupheleleyo lweepayipi zokukhupha umoya eziguquguqukayo kunye nobude, zonke eziyilwe kwaye zavunywa ukubonelela ngeenzuzo ezininzi xa zisetyenziswa kunye neendidi ezahlukeneyo zamafutha enjini ezikhoyo ngoku kwimarike yepetroliyam.
Iipayipi bezisetyenziswa ekufakweni kweenkqubo zepetroli kangangeminyaka engaphezu kwama-25, ngokuyintloko ukubonelela ngendawo yokudibanisa phakathi kwe-UST kunye nesixhobo sokukhupha ipetroli. Ukongeza, ngo-2004, i-UL/ULc yongeza igama elithi "Common Exhaust" kwi-UL-971 yayo ethi "Standard for the Safety of Nonmetallic Underground Piping for Flammable Liquids," nto leyo eyenza ipayipi eguquguqukayo ibe lolona khetho luphambili lokufakelwa kwenkqubo yepetroli. Ukuphatha iimveliso zolwelo kunye nokusetyenziswa komoya.
Iingenelo zombhobho oguquguqukayo xa usetyenziswa njengombhobho wokukhupha umoya we-UST ziyafana nezo zisetyenziswa xa kusenziwa izicelo zokuhambisa ipetroli:
Xa kuthelekiswa nezinye izinto ezisetyenziselwa ukwenza imibhobho yokungenisa umoya, imibhobho eguquguqukayo ikwabonelela ngezi zibonelelo zilandelayo:
I-OPW Retail Fueling eseSmithfield, NC yaqalisa uluhlu lwayo lwemveliso yeFlexWorks ngo-1996. Ukusukela ngoko, ngaphezulu kwe-10 yezigidi zeemitha zeepayipi eziguquguqukayo - ezidweliswe yi-UL zokungenisa umoya ngo-2007 - zithengisiwe ukuze zisetyenziswe kwi-motor fuels, kwi-high-mix fuels, kwi-richest fuels, nakwi-aircraft kunye ne-marine fuels kwihlabathi liphela.
I-OPW Flexible Tubing ifumaneka kwiindlela zodonga olunye noluphindwe kabini, kwaye ikwafumaneka ngobude obahlukeneyo kwiireyile okanye kwiindlela ezithe tyaba ezingama-25, 33, kunye “neentonga” ezithe tyaba ezingama-40 intshi ezinobubanzi obuyi-1.5, 2, kunye ne-3 intshi, ngokulandelelana. Ngokwe-PEI/RP 100-20 “Iindlela Ezicetyiswayo Zokufaka Iinkqubo Zokugcina Ulwelo Ezingaphantsi Komhlaba.” I-OPW idlula lee kune-PEI/RP 100-20 ecetywayo, ecetyisa ukuba imibhobho yokungenisa umoya ithambeke nge-1/4 intshi ngenyawo, hayi i-PEI eCetyisiweyo yi-1/8 intshi ngenyawo.
Uqhagamshelo lwemibhobho yokukhupha umoya eguquguqukayo kufuneka lwenziwe ngentsimbi engagqwaliyo kwaye lungafakwa kwiigumbi zotshintsho okanye kwi-sumps, ingakumbi kumazwe apho kufuneka khona imibhobho yodonga oluphindwe kabini. Ukuba izixhobo zentsimbi engagqwaliyo okanye iipani zeoyile eziguqukayo azifumaneki, uqhagamshelo kufuneka lusongelwe ngeteyipu yeDensyl™ (ekwaziwa ngokuba yiteyipu yamafutha okanye iteyipu yewax) ukuthintela ukugqwala.
Kwiminyaka engama-25 ukususela ekudalweni kwayo, i-OPW yenze uphuculo kumbhobho wayo oguquguqukayo weFlexWorks, kuquka ukwanda kokuguquguquka ngamandla amancinci okugoba kunye nokufakelwa okulula; ukunciphisa ubunzima bombhobho ukunciphisa iindleko zokuthumela; kunye nokunciphisa kakhulu inkumbulo yombhobho ukufikelela kuqhagamshelo olukhawulezayo kunye nokukwazi ukubeka umbhobho ngokuthe tyaba emseleni; kunye nokusebenzisa umbhobho oqinisiweyo weKynar® ADX (PVDF), oxineneyo kwaye omelana nokugcwala kwamanzi, okwenza ukuba ube ngowona ufanelekileyo ekuvezweni kolwelo kunye nomphunga.
Emva kwamashumi eminyaka ibonakalisa ukubaluleka kwayo njengenxalenye yeenkqubo zokuhambisa ipetroli phantsi komhlaba, ipayipi eguquguqukayo ngokukhawuleza iba lolona khetho lokuqala lokusetyenziswa kwepayipi yokukhupha umoya, kwaye ukuqhekeka kwefiberglass okwangoku sesinye isizathu sokuba ipayipi yokukhupha umoya eguquguqukayo ibe yindlela ethembekileyo endaweni yepayipi yokukhupha umoya eqinileyo okanye iityhubhu zefiberglass eziqinileyo.
