Umbhobho wegesi we-PE

Intshayelelo yoMbhobho weGesi we-PE

Imibhobho ye-PE yegesi yimibhobho yentsimbi yemveli kunye neemveliso zokutshintsha igesi yePVC. Imibhobho yegesi ye-GKBM PE iveliswa ngemigca yokuvelisa evela kumazwe angaphandle eBattenfeld-Cincinnati, eJamani. Izinto eziluhlaza zingeniswa ngaphandle kwezinto ezixubileyo ezikhethekileyo ezivela kwi-Borealis ME3440 kunye ne-HE3490LS, ezinomsebenzi ophezulu wokhuseleko. I-GKBM ifumene iLayisensi yokuVelisa izixhobo eziKhethekileyo kwiRiphabhlikhi yaBantu baseTshayina – iMibhobho yoxinzelelo lweMihlaba ekhutshwe nguLawulo Jikelele loLawulo loMgangatho, uHlolo kunye nokuValwa kweRiphabhlikhi yaseChina ngoJulayi 16, 2012, kwaye ivunyelwe ukuzibandakanya kwimveliso. yamacandelo emibhobho yoxinzelelo (imibhobho ye-polyethylene yodidi lwe-A2). Inombolo yesatifikethi: TS2710W16-2016.

Iinkcukacha zeMveliso

Iimpawu ze-PE Gas Pipe

I-1.Ukusebenza okuphezulu: Izixhobo zokuvelisa zisebenzisa umgca wokuqala wokuveliswa kwamanye amazwe ovela eBattenfeld-Cincinnati, eJamani. Iimathiriyeli ekrwada zingeniswa kwamanye amazwe izinto ezixubeneyo ezizodwa ezivela kwi-Borealis ME3440 kunye ne-HE3490LS. Imveliso inomsebenzi ophezulu wokhuseleko.

I-2.Umgangatho wemveliso ezinzileyo: Izixhobo zokuvavanya izinto eziluhlaza kunye neemveliso ezigqityiweyo zigqityiwe, kwaye iimveliso ziveliswa kwaye zihlolwe ngokuhambelana ne-GB15558. 1-2003 umgangatho.

I-3.Uxhulumaniso oluqinileyo, akukho kuvuza: Iinkqubo zemibhobho zixhunywe ngokufakela umbhobho we-electrofusion, kwaye amajoyina axhunyiwe ngokuqinileyo kwaye akayi kuvuza.

I-4.Ubomi benkonzo ende: imveliso iqulethe i-2-2.5% ye-carbon black esasazwa ngokufanayo, enokugcinwa okanye isetyenziswe ngaphandle kwi-air open for 50 iminyaka; Izinto ezingasebenziyo, ukuchasana kweekhemikhali ezilungileyo, iikhemikhali emhlabeni aziyi kubangela nayiphi na impembelelo yokuthotywa kombhobho;

I-5.I-Excellent stress-cracking resistance and wear resistance: Inamandla amakhulu okucheba, ukuxhathisa ukukrazula okugqwesileyo kunye nokuchasana kakuhle kokugqoka, okunokuthintela ngokufanelekileyo umonakalo kwinkqubo yokubhobhoza ngexesha lokwakha.

6.Ukuchasana okunamandla kwisiseko sokuzinzisa: Ubude bobude bombhobho wonikezelo lwamanzi we-HDPE ludlula i-500%, kwaye lukwazi ukuziqhelanisa nokuhlaliswa okungalinganiyo kwesiseko kunye nokusebenza okugqwesileyo kokuchasene nenyikima.

Ulwahlulo lombhobho wegesi we-PE

Kukho i-72 iyonke yeemveliso zepayipi yegesi ye-PE, eyahlulahlulwe yaba ziindidi ezimbini: i-PE80 kunye ne-PE100. Ngokoxinzelelo oluphezulu oluvumelekileyo lokusebenza, iimveliso zihlukaniswe ngamabakala ama-4: PN0.5MPa, PN0.3MPa, PN0.7MPa kunye ne-PN0.4MPa. ukusuka kwi-dn32- dn400 iyonke yeenkcukacha ze-18, ezisetyenziswa ikakhulu kuthutho lwegesi yendalo.
