4. Ukumelana nokugqwesa okuphezulu: Iipayipi zensimbi ze-DN300 zihlala ziphathwa ngonyango oluchasene ne-corrosion, olunokuthi luxhathise ngokufanelekileyo ukukhukuliseka kwezinto zeekhemikhali kunye neendaba ezitshabalalisayo kunye nokwandisa ubomi babo benkonzo.

Okwesibini, ukusetyenziswa kwepayipi yensimbi ye-DN300

Umbhobho wentsimbi we-DN300 unoluhlu olubanzi lokusetyenziswa, ngakumbi kubandakanya le miba ilandelayo:
1. Ukuthuthwa kweoli kunye negesi yendalo: Iipayipi zensimbi ze-DN300 zihlala zisetyenziselwa ukuthutha ioli kunye negesi yendalo kwaye zenze umsebenzi obalulekileyo wokudibanisa iindawo ezahlukeneyo. Ubukhulu bayo obukhulu kunye namandla aphakamileyo kwenza kube yinto efanelekileyo yokuthutha ioli kunye negesi.
2. Iiprojekthi zokwakha: Kwiiprojekthi ezinkulu zokwakha, ezifana neebhulorho, izakhiwo eziphakamileyo, njl., iipayipi zensimbi ze-DN300 zihlala zisetyenziselwa ukuxhasa izakhiwo, iitrasi, iikholomu ezithwala imithwalo, njl., ukuba zidlale indima ekuzinziseni. kunye nenkxaso.
3. Izixhobo zemizi-mveliso: Imibhobho yobubanzi obukhulu iyafuneka kwizixhobo ezininzi zoshishino. Iibhobho zetsimbi ze-DN300 zinokuhlangabezana neemfuno zezi zixhobo zemidiya yokuthutha, njengezixhobo zokuvelisa imichiza, izixhobo zokufudumeza, njl.
4. Ukunyangwa kwamanzi: Iipayipi zensimbi ze-DN300 zikwasetyenziswa ngokubanzi kwiinkqubo zokubonelela ngamanzi kunye neenkqubo zokuhambisa amanzi ukuthutha amanzi acocekileyo, ugutyulo kunye namanzi acociweyo.

Okwesithathu, inkqubo yokuvelisa i-DN300 yentsimbi yombhobho

Inkqubo yokuvelisa i-DN300 yentsimbi yombhobho idla ngokubandakanya la manyathelo alandelayo:
1. Ukulungiswa kwezinto: Khetha intsimbi efanelekileyo njengezinto eziluhlaza, ngokubanzi i-carbon steel, i-alloy steel, njl.
2. Ukucutshungulwa kombhobho ongenanto: Intsimbi iyasikwa, ifudunyezwe, kwaye igqojozwe ukwenza umbhobho ongenanto ubude obuthile.
3. Ukuqengqeleka okungenanto kombhobho: Ngokuqengqeleka kombhobho omninzi ongenanto kwindawo yokusila, umbhobho wentsimbi onobubanzi obufunekayo kunye nobukhulu bodonga uyenziwa ngokuthe ngcembe.
4. Ukuqulunqa kunye nokulungelelanisa: Umbhobho wensimbi ogqityiweyo ulungelelaniswa kwaye unqunywe ngomatshini wokwenza ukuba ube nenkangeleko echaziweyo kunye nobukhulu.
5. Unyango lwe-Welding: Weld umbhobho wensimbi njengoko kufunekayo ukuze uqinisekise ukunyaniseka kunye nokudibanisa kombhobho.
6. Unyango lomphezulu: Yenza unyango olungaphezulu olunjengokususwa komhlwa kunye nokunqanda ukubola kumbhobho wentsimbi ukuphucula ukuxhathisa ukudumba kunye nomgangatho wenkangeleko.
7. Ukuhlola kunye nokupakishwa: Ukuqhuba ukuhlolwa komgangatho ohlukeneyo kwimibhobho yensimbi ye-DN300 eveliswayo, njengokuhlola ubungakanani, ukuhlolwa kokusebenza komzimba, njl., kunye nephakheji kunye neleyibhile ukuze kube lula ukuthutha kunye nokusetyenziswa.

Ukushwankathela, ipayipi yensimbi ye-DN300, njengombhobho wensimbi oqhelekileyo osetyenziswa ngokuqhelekileyo, usetyenziswa ngokubanzi kumashishini kunye nemimandla yokwakha. Iimpawu zibandakanya ububanzi obukhulu, udonga olungqingqwa, ukusetyenziswa okubanzi, kunye nokumelana nokukhula okuphezulu. Ngeenkqubo ezifanelekileyo zokuvelisa, iipayipi zensimbi ze-DN300 ezinomgangatho ophezulu kunye nokusebenza okugqwesileyo kunokuveliswa ukuhlangabezana neemfuno ezahlukeneyo zobunjineli. Kuphuhliso lwexesha elizayo, kunye nokuqhubela phambili kwenzululwazi kunye nobuchwepheshe kunye nokuphuculwa kobuchwepheshe, i-DN300 ipayipi yensimbi iya kulungelelanisa ngakumbi kwiimfuno zazo zonke iinkalo zobomi kwaye yenze igalelo elikhulu kuphuhliso loluntu.
