Ipayipi yensimbi ye-DN550 ibhekisela kumbhobho wensimbi wobungakanani obuthile, apho "i-DN" isifinyezo se "Diameter Nominal", oku kuthetha "ububanzi obuqhelekileyo". Idayamitha yegama yisayizi esemgangathweni esetyenziselwa ukubonisa ubungakanani bemibhobho, izifakelo zemibhobho, kunye neevalvu. Kwishishini lombhobho wensimbi, yintoni i-diameter yangaphandle ye-DN550 yensimbi yombhobho? Impendulo imalunga nama-550 mm.

Umbhobho wensimbi ngumbhobho wentsimbi oqhelekileyo owenziwe ngentsimbi kwaye usetyenziswa ngokubanzi ekwakheni, ukuveliswa koomatshini, i-petrochemical, amandla ombane, i-aerospace, kunye nezinye iindawo. Umbhobho wensimbi uneenzuzo zamandla aphezulu, ukuxhathisa kwe-corrosion, kunye nokumelana nobushushu obuphezulu, ngoko ke isetyenziswe ngokubanzi kwiiprojekthi ezahlukeneyo kunye nokusetyenziswa.

Ukongeza kubukhulu bedayamitha yangaphandle ye-DN550 yentsimbi yombhobho, sinokuqonda ezinye iiparitha ezibalulekileyo ezinxulumene nemibhobho yentsimbi, njengobunzima bodonga, ubude kunye nezinto eziphathekayo.

1. Ubukhulu bodonga: Ubukhulu bodonga bubhekisela kubukhulu bombhobho wensimbi, ngokuqhelekileyo ubonakaliswe ngeemilimitha okanye i-intshi. Ubunzima bodonga lombhobho wensimbi buhambelana ngokusondeleyo nobubanzi bayo, kwaye iimeko ezahlukeneyo zesicelo kunye neemfuno nazo zineemfuno ezahlukeneyo zobunzima bodonga.
2. Ubude: Ubude bemibhobho yensimbi ngokuqhelekileyo bulungelelaniswa, kwaye ubude obuqhelekileyo bubandakanya iimitha ezi-6, iimitha ezili-9, iimitha ezili-12, njl. Ngokuqinisekileyo, phantsi kweemfuno ezikhethekileyo, ubude bunokulungiswa ngokweemfuno zabathengi.
3. Izinto eziphathekayo: Zininzi iintlobo zezixhobo zemibhobho yensimbi, kwaye eziqhelekileyo ziyimibhobho ye-carbon steel, i-stainless steel pipes, i-alloy steel pipes, njl. Izinto ezahlukeneyo zineempawu ezahlukeneyo kunye nemida esebenzayo. Xa ukhetha iipayipi zetsimbi, kuyimfuneko ukwenza ukhetho olufanelekileyo olusekelwe kwiimfuno ezithile zokusetyenziswa.

Emva kokuqonda ulwazi olusisiseko lwe-diameter yangaphandle ye-DN550 yentsimbi yombhobho, sinokuphinda sihlolisise ezinye izihloko ezinxulumene nemibhobho yentsimbi, njengenkqubo yokuvelisa, ukusetyenziswa, kunye nemfuno yemarike.
1. Inkqubo yokuvelisa: Inkqubo yokwenziwa kwemibhobho yentsimbi ikakhulu ibandakanya imibhobho engenamthungo kunye nemibhobho edityanisiweyo. Imibhobho engenamthungo yenziwa ngokufudumeza i-billet yensimbi kwiqondo lobushushu elithile ize iyolule okanye igqobhoze. Banamandla aphezulu kunye nokutywinwa. Imibhobho edityanisiweyo yenziwe ngokugoba iipleyiti zentsimbi zibe yimilo ye-tubular kwaye emva koko i-welding. Inkqubo yokuvelisa ilula kwaye ixabiso liphantsi.
2. Ukusetyenziswa: Imibhobho yentsimbi inoluhlu olubanzi lokusetyenziswa. Zingasetyenziselwa ukuthutha ulwelo, iigesi, kunye nezinto eziqinileyo, kwaye zingasetyenziselwa ukwakha izakhiwo ezahlukeneyo kunye nezixhaso. Ngokomzekelo, kwishishini lepetrochemical, imibhobho yentsimbi isetyenziswa kakhulu ukuthutha ioli, igesi yendalo, kunye neemveliso zemichiza; kwishishini lokwakha, iipayipi zetsimbi zisetyenziselwa ukwakha izakhiwo zetsimbi, ukuxhasa izitebhisi ezithwele iindonga, njl.
3. Imfuno yemarike: Ngophuhliso loqoqosho kunye nenkqubela phambili yoshishino, imfuno yemarike yeepayipi zensimbi iye yanda ngonyaka. Ngokukodwa kulwakhiwo lweziseko ezingundoqo, ukwakhiwa kweedolophu, kunye nophuhliso lwemizi-mveliso, kukho imfuno enkulu yemibhobho yentsimbi. Ngoko ke, ishishini lombhobho wensimbi liye lahlala lishishini elinamandla kunye nokukhuphisana.

Isishwankathelo, ububanzi bangaphandle bombhobho wensimbi we-DN550 malunga ne-550 mm. Yinkcazo yepayipi yensimbi eqhelekileyo kwaye isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo. Abantu abakwishishini lensimbi kufuneka baqonde iinkcukacha zeemibhobho zetsimbi, ezinceda ukukhetha iibhobho zensimbi ezifanelekileyo kunye nokufezekisa iziphumo ezilungileyo kwizicelo eziphathekayo. Ngophuhliso loqoqosho kunye nokuqhubela phambili kobuchwepheshe, ishishini lombhobho wensimbi liya kuqhubeka likhula kwaye lihlangabezane neemfuno zemibhobho yentsimbi kwiinkalo ezahlukeneyo. Masijonge phambili kwishishini lombhobho wensimbi ukudala ikamva elingcono kuphuhliso lwexesha elizayo!
