1. Inkcazo ye-DN80 yombhobho wensimbi
I-DN80 yentsimbi yombhobho ibhekisela kumbhobho wentsimbi owenziwe ngesinyithi kunye nobubanzi obungaphandle obuyi-80 mm kunye nobukhulu bodonga lwe-3.5 mm. Ingumbhobho wensimbi ophakathi, osetyenziselwa ukuthutha kunye neenjongo zesakhiwo kumashishini afana nolwelo, iigesi, i-petroleum, iikhemikhali, ukwakha iinqanawa kunye noomatshini.

2. Imigangatho ye-DN80 yemibhobho yentsimbi
Kukho imigangatho emibini ye-DN80 yeepayipi zensimbi: imigangatho yasekhaya kunye nemigangatho yamazwe ngamazwe. Imigangatho yasekhaya ikakhulu i-GB / T 3091-2015 "I-Welded Steel Pipe" kunye ne-GB / T 13793-2016 "I-Long Straight Welded Seam Steel Pipe". Imigangatho yamazwe ngamazwe ikakhulu ASTM A53, BS1387, EN10255, DIN2440, njl. Le migangatho inezibonelelo ezithile eziphathekayo, ukwakheka kweekhemikhali, iimpawu zoomatshini, ubukhulu, ubunzima, kunye nokumakishwa kwe-DN80 imibhobho yentsimbi, eqinisekisa umgangatho kunye nokusetyenziswa kwe imibhobho yentsimbi.

3. Ubungakanani boluhlu lwe-DN80 yombhobho wentsimbi
Ubungakanani bobungakanani bepayipi yensimbi ye-DN80 inqunywe ngokwemigangatho kazwelonke nakwamanye amazwe. Ngokwemigangatho yasekhaya ye-GB / T 3091-2015 "I-Welded Steel Pipe" kunye ne-GB / T 13793-2016 "I-Long Straight Welded Seam Steel Pipe", uluhlu lobungakanani be-DN80 yombhobho wentsimbi owenziwe ngamazimba ngolu hlobo lulandelayo:
Ubukhulu bangaphandle: 76.1 ~ 81.0 mm
Ubunzima bodonga: 3.0 ~ 3.5 mm
Ubude: ngokubanzi iimitha ezi-6, kwaye zinokwenziwa ngokweemfuno zomsebenzisi.

4. Izinto eziluncedo kunye nokungonakali kwe-DN80 yombhobho wentsimbi
Iingenelo ze-DN80 zentsimbi yombhobho yentsimbi zixhathisa kakuhle, ukuxhathisa ukubola, ubomi benkonzo ende, ixabiso eliphantsi, ukwakhiwa okulula, njl.; izinto ezingeloncedo zinzima kwaye kulula ukurusa. Nangona kunjalo, emva kwe-galvanizing, ukuchasana kwayo kwe-corrosion kuye kwaphuculwa kakhulu, okunokuthi kuphephe ngokufanelekileyo ukugqwala kunye nokubola kwemibhobho yensimbi kunye nokuqinisekisa ubomi benkonzo.

5. Iinkalo zesicelo ze-DN80 zemibhobho yensimbi
Imibhobho yentsimbi yentsimbi ye-DN80 isetyenziswa ngokubanzi kulwakhiwo, uthutho, i-petroleum, ishishini lemichiza, isinyithi, oomatshini, i-aerospace, kunye namanye amashishini. Ikakhulu zisetyenziselwa ukuthutha amanzi, igesi, i-oyile, umphunga, kunye nezinye izixhobo zeendaba. Zingasetyenziselwa ukwenza iibhulorho, izakhiwo zokwakha, iinxalenye zoomatshini, njl.

Ngamafutshane, i-DN80 ipayipi yensimbi luhlobo oluqhelekileyo olusetyenziswayo lombhobho wensimbi kunye nokumelana nokugqwala okulungileyo kunye nobomi benkonzo ende. Ngenye yezinto ezikhethiweyo zothutho kunye neenjongo zesakhiwo kumashishini ahlukeneyo.
