Kune varidzi vezviteshi zvepeturu nevashandi, zvikamu zvemapombi nemafuta zvakagadzirwa nefiberglass pari zvino zvakaoma kuwana nekuda kwekushomeka kwe resin, zvichiita kuti zviome kuwana ma vent tube (UST) ekuisa matangi ekuchengetera pasi pevhu. Kushomeka uku kunotadzisa kuiswa kwemasystem matsva kana akagadziridzwa, sezvo exhaust iri chikamu chinodiwa mukuisa mafuta sezvo ichimhanya kubva kuUST kuenda ku pressure vacuum exhaust yesystem.
Mutsetse wemhepo unokosha pakushanda kweUST system sezvo uchibvumira tangi kuti ribude kana kumanikidzwa kwaro kwemukati kana vacuum kwapfuura nzvimbo yakati, zvichibvumira tangi kuti "rifeme". Kunyange hazvo kushomeka kwefiberglass kuri dambudziko, pane mhinduro yakasimbiswa: nzira dzekufema dzinochinjika.
Mapaipi Emhepo Asina KugumbukaOPW inopa huwandu hwakakwana hwemapombi emhepo anochinjika uye kureba, ese akagadzirwa uye akatenderwa kupa mabhenefiti akawanda kana achishandiswa nemafuta akasiyana-siyana einjini aripo pari zvino mumusika wepeturu.
Mapombi ave achishandiswa mukuisa masisitimu emafuta kwemakore anopfuura makumi maviri nemashanu, kunyanya kupa nzvimbo yekubatanidza pakati peUST nechinhu chinopa mafuta. Pamusoro pezvo, muna 2004, UL/ULc yakawedzera zita rekuti "Common Exhaust" kune yayo UL-971 "Standard for the Safety of Nonmetallic Underground Piping for Fireable Liquids," zvichiita kuti pombi inochinjika ive sarudzo yekutanga yekuisa masisitimu emafuta. Kubata zvigadzirwa zvemvura uye mashandisirwo emhepo.
Zvakanakira zvepaipi inochinjika kana ichishandiswa sepombi yeUST vent zvakafanana nepainoshandiswa mukutumira mafuta:
Zvichienzaniswa nezvimwe zvinoshandiswa kugadzira mapaipi ekufema, mapaipi anochinjika anopawo zvakanakira zvinotevera:
Kambani yeOPW Retail Fueling iri kuSmithfield, NC yakatanga chigadzirwa chayo cheFlexWorks muna 1996. Kubva ipapo, mapaipi anochinjika anopfuura mamiriyoni gumi - akanyoreswa neUL kuti apinzwe mhepo muna 2007 - akatengeswa kuti ashandiswe mumafuta emota, mafuta anosanganiswa zvakanyanya, mafuta akapfuma, uye mafuta endege neemugungwa pasi rese.
OPW Flexible Tubing inowanikwa mumadziro maviri kana maviri, uye inowanikwawo muhurefu hwakasiyana-siyana pamareels kana mu "matanda" akatsetseka ane 25, 33, uye 40 foot ane dhayamita ye 1.5, 2, uye 3 inches, zvichiteerana. Sekureva kwePEI/RP 100-20 "Maitiro Anokurudzirwa Ekuisa Underground Liquid Storage Systems." OPW inopfuura zvinokurudzirwa nePEI/RP 100-20, iyo inokurudzira kuti machubhu emhepo atsvedzerere 1/4 inch pa foot, kwete PEI Inokurudzirwa 1/8 inch pa foot.
Mapaipi emagetsi anochinjika anofanira kugadzirwa nesimbi isina ngura uye anogona kuiswa mumakamuri ekuchinja kana ma sump, kunyanya munzvimbo dzinodiwa mapaipi emadziro maviri. Kana zvisungo zvesimbi isina ngura kana mapani emafuta ekuchinja asingasviki, zvinofanirwa kuputirwa netepi yeDensyl™ (inozivikanwawo setepi yemafuta kana tepi yewakisi) kudzivirira ngura.
Mumakore makumi maviri nemashanu kubva payakagadzirwa, OPW yakagadziridzwa pombi yayo inochinjika yeFlexWorks, kusanganisira kuwedzera kuchinjika nesimba diki rekukotama uye kuiswa kuri nyore; kuderedza huremu hwepombi kuderedza mari yekutumira; uye kuderedza zvakanyanya memory yepombi kuti pave nekubatana nekukurumidza uye kugona kuisa pombi yakati sandara mumugero; uye kushandisa Kynar® ADX (PVDF) pipe liner yakasimbiswa, iyo ine simba uye inodzivirira kupinda mumvura, zvichiita kuti ive yakakodzera kusvibiswa nemvura neutsi.
Mushure memakumi emakore ekuratidza kukosha kwayo sechikamu chemasisitimu ekutumira mafuta pasi pevhu, mapaipi anochinjika ari kukurumidza kuva sarudzo yekutanga yekushandisa mapaipi anopinza mhepo, uye kupwanyika kwefiberglass pari zvino ndicho chimwe chikonzero nei mapaipi anochinjika emhepo ari imwe nzira yakavimbika pane mapaipi anopinza mhepo akaomarara kana kuti mapaipi efiberglass asina kuomarara.
