Umbhobho wegesi we-PE
Intshayelelo yePe Gas Pipe
Iipayipi ze-PE zegesi ziipayipi zentsimbi zemveli kunye neemveliso zokutshintshwa kwegesi ze-PVC. Iipayipi zegesi ze-GKBM PE ziveliswa ziintambo zemveliso ezingenisiweyo ezivela eBattenfeld-Cincinnati, eJamani. Ezi zinto ziluhlaza zivela kwamanye amazwe kwiBorealis ME3440 kunye ne-HE3490LS, ezisebenza ngokhuseleko oluphezulu. I-GKBM ifumene iLayisensi yokuVelisa izixhobo ezikhethekileyo zeRiphabliki yabantu baseTshayina – iiComponents zoMbhobho woXinzelelo ekhutshwe yi-General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China ngoJulayi 16, 2012, kwaye ivumelekile ukubandakanyeka ekuveliseni izixhobo zombhobho woxinzelelo (iipayipi ze-polyethylene ze-A2 grade). Inombolo yeSatifikethi: TS2710W16-2016.
Iimpawu zePe Gas Pipe
1. Ukusebenza okuphezulu: Izixhobo zemveliso zisebenzisa umgca wokuqala wemveliso ongeniswe eBattenfeld-Cincinnati, eJamani. Izinto ezisetyenzisiweyo zingeniswa zizinto ezikhethekileyo ezixutyiweyo ezivela eBorealis ME3440 kunye neHE3490LS. Le mveliso inamandla aphezulu okhuseleko.
2. Umgangatho wemveliso ozinzileyo: Izixhobo zokuvavanya izinto eziluhlaza kunye neemveliso ezigqityiweyo zigqityiwe, kwaye iimveliso ziveliswa kwaye zihlolwe ngokuhambelana ngokungqongqo nomgangatho we-GB15558. 1-2003.
3. Uqhagamshelo oluqinileyo, akukho kuvuza: Iinkqubo zemibhobho ziqhagamshelwe ngezixhobo zombhobho we-electrofusion, kwaye amalungu aqhagamshelwe ngokuqinileyo kwaye awayi kuvuza.
4.Ixesha elide lenkonzo: imveliso ine-2-2.5% ye-carbon black esasazwa ngokulinganayo, enokugcinwa okanye isetyenziswe ngaphandle emoyeni ovulekileyo kangangeminyaka engama-50; Izinto ezingasebenziyo, ukumelana kakuhle kweekhemikhali, iikhemikhali ezisemhlabeni aziyi kubangela naluphi na uphazamiseko kumbhobho;
5. Ukumelana okugqwesileyo noxinzelelo kunye nokumelana nokuguguleka: Inamandla aphezulu okucheba, ukumelana nokukrwela okugqwesileyo kunye nokumelana nokuguguleka okuhle, okunokuthintela ngempumelelo ukonakala kwenkqubo yemibhobho ngexesha lokwakha.
6. Ukumelana okunamandla nokuhlaliswa kwesiseko: Ukwandiswa kodonga xa kuqhekeka umbhobho wamanzi we-HDPE kudlula i-500%, kwaye iyakwazi ukuzivumelanisa nokungalingani kokuhlaliswa kwesiseko kunye nokusebenza okugqwesileyo kokulwa nokushukuma komhlaba.
Ulwahlulo lweMibhobho yeGesi yePE
Kukho iimveliso zepayipi zegesi ze-PE ezingama-72, ezahlulwe zibe ziintlobo ezimbini: i-PE80 kunye ne-PE100. Ngokwexinzelelo lokusebenza oluphezulu oluvumelekileyo, iimveliso zahlulwe zibe ziiklasi ezi-4: i-PN0.5MPa, i-PN0.3MPa, i-PN0.7MPa kunye ne-PN0.4MPa. ukusuka kwi-dn32-dn400, iinkcukacha ezili-18 zizonke, ezisetyenziswa kakhulu ekuthuthweni kwegesi yendalo.
