Kwa eni malo ogulitsa mafuta ndi ogwiritsa ntchito, zida zopangira mapaipi ndi zida zopangira mafuta zochokera ku fiberglass pakadali pano zimakhala zovuta kupeza chifukwa cha kusowa kwa resin, zomwe zimapangitsa kuti zikhale zovuta kupeza ma vent tube (UST) oyika matanki osungira pansi pa nthaka. Kusowa kumeneku kumalepheretsa kuyika ma system atsopano kapena okonzedwanso, chifukwa utsi ndi gawo lofunikira pakuyika mafuta chifukwa umayenda kuchokera ku UST kupita ku utsi wa vacuum wa pressure system.
Mzere wotulutsira mpweya ndi wofunikira kwambiri pakugwira ntchito kwa dongosolo la UST chifukwa umalola thanki kutulutsa mpweya pamene kupanikizika kwake kwamkati kapena vacuum kwapitirira malo enaake, zomwe zimapangitsa kuti thankiyo "ipume". Ngakhale kusowa kwa fiberglass mosakayikira ndi vuto, pali njira yodziwikiratu komanso yotsimikizika: njira zopumira mpweya zosinthasintha.
Mapaipi Otulutsa Mpweya Opanda KukhumudwaOPW imapereka mitundu yonse ya mapaipi otulutsa utsi osinthasintha komanso kutalika, zomwe zonse zapangidwa ndikuvomerezedwa kuti zipereke zabwino zambiri zikagwiritsidwa ntchito ndi mafuta osiyanasiyana a injini omwe alipo pamsika wamafuta.
Mapayipi akhala akugwiritsidwa ntchito poyika makina amafuta kwa zaka zoposa 25, makamaka kuti apereke malo olumikizirana pakati pa UST ndi chotulutsira mafuta. Kuphatikiza apo, mu 2004, UL/ULc idawonjezera dzina la "Common Exhaust" ku UL-971 "Standard for the Safety of Nonmetallic Underground Piping for Fireable Liquids," zomwe zimapangitsa kuti chitoliro chosinthasintha chikhale chisankho choyamba pakuyika makina amafuta. Kusamalira zinthu zamadzimadzi ndi kugwiritsa ntchito njira zotulutsira mpweya.
Ubwino wa chitoliro chosinthasintha chikagwiritsidwa ntchito ngati chitoliro chotulutsira mpweya cha UST ndi wofanana ndi womwe umagwiritsidwa ntchito popereka mafuta:
Poyerekeza ndi zipangizo zina zomwe zimagwiritsidwa ntchito popanga mapaipi opumira mpweya, mapaipi osinthasintha amaperekanso zabwino zotsatirazi:
Kampani ya OPW Retail Fueling yokhala ku Smithfield, NC idayambitsa mzere wake wazinthu za FlexWorks mu 1996. Kuyambira pamenepo, mapaipi opitilira mamita 10 miliyoni - omwe adalembedwa ndi UL kuti azipumira mpweya mu 2007 - agulitsidwa kuti agwiritsidwe ntchito mu mafuta amagetsi, mafuta osakanikirana kwambiri, mafuta olemera, ndi mafuta oyendetsa ndege ndi am'madzi padziko lonse lapansi.
Machubu Osinthasintha a OPW amapezeka m'makoma amodzi ndi awiri, ndipo amapezekanso m'mautali osiyanasiyana pa ma reel kapena mu "ndodo" zathyathyathya za mapazi 25, 33, ndi 40 zokhala ndi mainchesi 1.5, 2, ndi 3 motsatana. Malinga ndi PEI/RP 100-20 "Njira Zovomerezeka Zokhazikitsira Makina Osungira Madzi Otsika Pansi pa Dziko." OPW imapitilira kuposa momwe PEI/RP 100-20 imalimbikitsira, yomwe imalimbikitsa kuti ma ducts opumira azikhala otsetsereka 1/4 inchi pa phazi, osati PEI Recommended 1/8 inchi pa phazi.
Mapaipi olumikizira utsi osinthasintha ayenera kupangidwa ndi chitsulo chosapanga dzimbiri ndipo akhoza kuphatikizidwa m'zipinda zosinthira kapena m'ma sump, makamaka m'maiko omwe mapaipi awiri amafunikira. Ngati palibe zolumikizira zachitsulo chosapanga dzimbiri kapena mapaipi osinthira mafuta, zolumikizira ziyenera kukulungidwa ndi tepi ya Densyl™ (yomwe imadziwikanso kuti tepi yamafuta kapena tepi ya sera) kuti ipewe dzimbiri.
Kwa zaka 25 kuchokera pamene idakhazikitsidwa, OPW yasintha chitoliro chake chosinthasintha cha FlexWorks, kuphatikizapo kusinthasintha kwakukulu ndi mphamvu zochepa zopindika komanso kuyika kosavuta; kuchepetsa kulemera kwa chitoliro kuti muchepetse ndalama zotumizira; komanso kuchepetsa kwambiri kukumbukira chitoliro kuti mupeze kulumikizana mwachangu komanso kuthekera koyika chitolirocho pansi pa ngalande; ndikugwiritsa ntchito chitoliro cholimba cha Kynar® ADX (PVDF), chomwe ndi cholimba komanso cholimba kuti chisalowe madzi ndi nthunzi, zomwe zimapangitsa kuti chikhale choyenera kugwiritsidwa ntchito ndi madzi ndi nthunzi.
Pambuyo pa zaka makumi ambiri akuwonetsa kufunika kwake ngati gawo la njira zoperekera mafuta pansi pa nthaka, mapaipi osinthasintha akukhala chisankho choyamba chogwiritsa ntchito mapaipi otulutsa mpweya, ndipo kuphulika kwa fiberglass komwe kulipo pano ndi chifukwa china chomwe chitoliro chosinthira mpweya chimakhala njira yodalirika m'malo mwa chitoliro cholimba kapena mapaipi a fiberglass osasunthika.

Gawani momwe malonda amagwirira ntchito pa zakumwa, makeke, golosale, chakudya chopakidwa/utumiki wazakudya ndi zokhwasula-khwasula.
Winsight ndi kampani yotsogola yopereka chithandizo cha chidziwitso cha B2B yomwe imayang'ana kwambiri makampani azakudya ndi zakumwa, kutumikira atsogoleri a mabizinesi m'njira zonse (masitolo ogulitsa zinthu zosavuta, ogulitsa zakudya, malo odyera ndi ntchito zogulitsa zakudya) kuti ogula agule chakudya ndi zakumwa kudzera m'manyuzipepala, zochitika, deta. Imapereka chidziwitso ndi zinthu zanzeru pamsika, ntchito zolangizira ndi ziwonetsero zamalonda.
