Kubanikazi beziteshi zikaphethiloli kanye nabaqhubi, izingxenye zamapayipi kanye nezinhlelo zokufaka uphethiloli ezisekelwe ku-fiberglass okwamanje kunzima ukuzithola ngenxa yokushoda kwe-resin, okwenza kube nzima ukuthola ukufakwa kwe-vent tube (UST) yamatangi okugcina angaphansi komhlaba. Lokhu kushoda kuphazamisa ukufakwa kwezinhlelo ezintsha noma ezithuthukisiwe, njengoba i-exhaust iyisici esidingekayo ekufakweni kukaphethiloli njengoba isuka ku-UST iye ku-vacuum exhaust yokucindezela kohlelo.
Ulayini womoya ubalulekile ekusebenzeni kohlelo lwe-UST njengoba uvumela ithangi ukuthi likhiphe umoya lapho ingcindezi yalo yangaphakathi noma i-vacuum idlula iphuzu elithile, okuyisisekelo okuvumela ithangi ukuthi "liphefumule". Nakuba ukuntuleka kwe-fiberglass ngokungangabazeki kuyinkathazo, kukhona ikhambi elisebenzayo neliqinisekisiwe: imigudu yomoya eguquguqukayo.
Amapayipi Omoya Angenakho Ukukhungatheka I-OPW inikeza uhla oluphelele lobukhulu nobude bamapayipi okukhipha umoya aguquguqukayo, konke okuklanyelwe futhi kwavunyelwa ukuhlinzeka ngezinzuzo eziningi uma kusetshenziswa uphethiloli wenjini ohlukahlukene otholakala emakethe kaphethiloli njengamanje.
Amapayipi asetshenziswe ekufakweni kwesistimu kaphethiloli iminyaka engaphezu kwengu-25, ikakhulukazi ukuhlinzeka ngendawo yokuxhumana phakathi kwe-UST kanye nesisabalalisi sikaphethiloli. Ngaphezu kwalokho, ngo-2004, i-UL/ULc yengeza igama elithi “Common Exhaust” ku-UL-971 yayo ethi “Standard for the Safety of Nonmetallic Underground Piping for Flammable Liquids,” okwenza ipayipi eliguquguqukayo libe yisinqumo sokuqala sokufakwa kwesistimu kaphethiloli. Ukuphatha imikhiqizo yoketshezi kanye nezicelo zokukhipha umoya.
Izinzuzo zepayipi eliguquguqukayo uma lisetshenziswa njengepayipi lokungenisa umoya le-UST ziyafana nalapho lisetshenziswa ekulethweni kukaphethiloli:
Uma kuqhathaniswa nezinye izinto ezisetshenziswa ukukhiqiza amapayipi okungenisa umoya, amapayipi aguquguqukayo nawo anikeza izinzuzo ezilandelayo:
I-OPW Retail Fueling eseSmithfield, NC yethule umkhiqizo wayo we-FlexWorks ngo-1996. Kusukela ngaleso sikhathi, amapayipi aguquguqukayo angaphezu kwamamitha ayizigidi eziyi-10 - abhalwe yi-UL ukuze asetshenziswe ekuphefumuleni ngo-2007 - athengiswe ukuze asetshenziswe kumafutha ezimoto, amafutha axubile kakhulu, amafutha acebile, kanye namafutha ezindiza kanye nawolwandle emhlabeni jikelele.
I-OPW Flexible Tubing iyatholakala ngezindlela zokwakheka zodonga olulodwa nolubili, futhi iyatholakala nangobude obuhlukahlukene kuma-reels noma “ezindongeni” eziyisicaba ezingamafidi angu-25, 33, kanye no-40 ezinobubanzi obuyi-1.5, 2, kanye no-3 amayintshi, ngokulandelana. Ngokusho kwe-PEI/RP 100-20 “Imikhuba Enconywayo Yokufaka Izinhlelo Zokugcina Uketshezi Ngaphansi Komhlaba.” I-OPW empeleni idlula okunconywa yi-PEI/RP 100-20, encoma ukuthi imibhobho yokungenisa umoya ithambekele ku-1/4 intshi ngonyawo, hhayi i-PEI Enconywa yi-1/8 intshi ngonyawo.
Ukuxhumeka kwamapayipi okukhipha umoya okuguquguqukayo kufanele kwenziwe ngensimbi engagqwali futhi kungafakwa emakamelweni okushintsha noma ezihlanjeni, ikakhulukazi ezifundazweni lapho kudingeka khona amapayipi odonga oluphindwe kabili. Uma izinto zokufakelwa kwensimbi engagqwali noma amapani kawoyela okuguqukayo zingatholakali, ukuxhumeka kufanele kusongwe ngetheyipu yeDensyl™ (eyaziwa nangokuthi i-grease tape noma i-wax tape) ukuvimbela ukugqwala.
Eminyakeni engama-25 selokhu yasungulwa, i-OPW yenze ngcono ipayipi layo eliguquguqukayo le-FlexWorks, okuhlanganisa ukuguquguquka okwandisiwe ngamandla amancane okugoba kanye nokufakwa okulula; ukunciphisa isisindo sepayipi ukunciphisa izindleko zokuthumela; kanye nokunciphisa kakhulu inkumbulo yepayipi ukuze kufezwe ukuxhumana okusheshayo kanye nekhono lokubeka ipayipi phansi emseleni; kanye nokusebenzisa ipayipi eliqinisiwe le-Kynar® ADX (PVDF), eliqinile futhi elimelana kakhulu nokugcwala kwamanzi, okwenza libe yindawo ekahle yokuvezwa uketshezi kanye nomhwamuko.
Ngemva kwamashumi eminyaka okufakazela ukubaluleka kwayo njengengxenye yezinhlelo zokulethwa kukaphethiloli ngaphansi komhlaba, ipayipi eliguquguqukayo liba yisinqumo sokuqala sokusetshenziswa kwamapayipi omoya, futhi ukuqhekeka kwe-fiberglass kwamanje kungenye yezizathu ezenza ipayipi lomoya eliguquguqukayo libe yindlela ethembekile esikhundleni sepayipi lomoya eliqinile noma amapayipi e-fiberglass aqinile kancane.

I-Top 202 ichaza kabanzi ngezinkampani ezinkulu embonini yezitolo ezithengisa izinto ezishibhile kanye nezindaba ezinkulu ze-M&A zonyaka odlule.
Ukuthengisa ngezigaba kweziphuzo, amaswidi, ukudla, ukudla okupakishiwe/isevisi yokudla kanye nokudla okulula.
I-Winsight iyinkampani ehamba phambili yezinsizakalo zolwazi ze-B2B egxile embonini yokudla neziphuzo, ikhonza abaholi bebhizinisi kuzo zonke iziteshi (izitolo ezilula, izitolo zokudla, izindawo zokudlela kanye nezinsizakalo zokudla ezingezona ezentengiselwano) ukuze abathengi bathenge ukudla neziphuzo ngemidiya, imicimbi, idatha. Ihlinzeka ngemikhiqizo yokuqonda kanye nobuhlakani bemakethe, izinsizakalo zokubonisana kanye nemibukiso yezohwebo.
