Ipayipi lensimbi le-DN550 libhekisela epayipini lensimbi losayizi othize, lapho elithi "DN" liyisifinyezo se-"Diameter Nominal", okusho ukuthi "ububanzi obujwayelekile". Ububanzi obujwayelekile buwusayizi ojwayelekile osetshenziselwa ukukhombisa ubukhulu bamapayipi, ukufakwa kwamapayipi, namavalvu. Embonini yamapayipi ensimbi, buyini ububanzi obungaphandle bepayipi lensimbi le-DN550? Impendulo imayelana 550 mm.

Ipayipi lensimbi liyipayipi elivamile lensimbi elenziwe ngensimbi futhi lisetshenziswa kabanzi ekwakhiweni, ukukhiqizwa kwemishini, i-petrochemical, amandla kagesi, i-aerospace, neminye imikhakha. Ipayipi lensimbi linezinzuzo zamandla aphezulu, ukumelana nokugqwala, nokumelana nokushisa okuphezulu, ngakho-ke lisetshenziswe kabanzi kumaphrojekthi ahlukahlukene kanye nezicelo.

Ngaphezu kobukhulu bobubanzi obungaphandle bepayipi lensimbi le-DN550, singaqonda futhi eminye imingcele ebalulekile ehlobene namapayipi ensimbi, njengokujiya kodonga, ubude, nezinto ezibonakalayo.

1. Ukujiya kodonga: Ukujiya kodonga kubhekisela ebukhulu bepayipi lensimbi, ngokuvamile elivezwa ngamamilimitha noma amayintshi. Ukuqina kodonga lwepayipi lensimbi kuhlobene eduze nobubanzi balo, futhi izimo ezihlukene zohlelo lokusebenza kanye nezidingo nazo zinezidingo ezihlukene zokuqina kodonga.
2. Ubude: Ubude bamapayipi ensimbi ngokuvamile bulinganiselwe, futhi ubude obuvamile buhlanganisa amamitha angu-6, amamitha angu-9, amamitha angu-12, njll Yiqiniso, ngaphansi kwezidingo ezikhethekile, ubude bungenziwa ngokwezifiso ngokuvumelana nezidingo zamakhasimende.
3. Impahla: Kunezinhlobo eziningi zezinto zokwakha amapayipi ensimbi, futhi ezivamile amapayipi ensimbi ye-carbon, amapayipi ensimbi engagqwali, amapayipi ensimbi ye-alloy, njll. Izinto ezihlukene zinezici ezahlukene kanye nobubanzi obusebenzayo. Lapho ukhetha amapayipi ensimbi, kuyadingeka ukwenza izinqumo ezifanele ngokusekelwe ezidingweni ezithile zokusetshenziswa.

Ngemva kokuqonda ulwazi oluyisisekelo lobubanzi obungaphandle bepayipi lensimbi le-DN550, singaqhubeka sihlola ezinye izihloko ezihlobene namapayipi ensimbi, njengenqubo yokukhiqiza, ukusetshenziswa, kanye nesidingo semakethe.
1. Inqubo yokukhiqiza: Inqubo yokukhiqiza amapayipi ensimbi ikakhulukazi ihlanganisa amapayipi angenamthungo namapayipi ashiselwe. Amapayipi angenamthungo enziwa ngokushisisa i-billet yensimbi emazingeni okushisa athile bese eyawelula noma ayibhoboze. Zinamandla aphezulu kanye nokuvala uphawu. Amapayipi ashiselwe enziwa ngokugoba amapuleti ensimbi abe ama-tubular shapes bese ewashisela. Inqubo yokukhiqiza ilula futhi izindleko ziphansi.
2. Ukusetshenziswa: Amapayipi ensimbi anezinhlobonhlobo zokusetshenziswa. Angasetshenziselwa ukuthutha uketshezi, amagesi, nezinto eziqinile, futhi angasetshenziswa ukwakha izakhiwo nezisekelo ezihlukahlukene. Ngokwesibonelo, embonini ye-petrochemical, amapayipi ensimbi asetshenziswa kakhulu ukuthutha uwoyela, igesi yemvelo, nemikhiqizo yamakhemikhali; embonini yokwakha, amapayipi ensimbi asetshenziselwa ukwakha izakhiwo zensimbi, ukusekela izitebhisi ezithwala izindonga, njll.
3. Isidingo semakethe: Ngokuthuthuka komnotho kanye nenqubekela phambili yezimboni, isidingo semakethe samapayipi ensimbi siye sakhula unyaka nonyaka. Ikakhulukazi ekwakhiweni kwengqalasizinda, ukwakhiwa kwamadolobha, nokuthuthukiswa kwezimboni, kunesidingo esikhulu samapayipi ensimbi. Ngakho-ke, imboni yamapayipi ensimbi ibilokhu iyimboni enamandla nokuncintisana.

Kafushane, ububanzi obungaphandle bepayipi yensimbi ye-DN550 cishe bungama-550 mm. Kuyinto evamile yokucaciswa kwepayipi yensimbi futhi isetshenziswa kabanzi emikhakheni ehlukahlukene. Abantu embonini yensimbi kudingeka baqonde ukucaciswa kwamapayipi ensimbi, okusiza ukukhetha amapayipi ensimbi afanele futhi kuzuzwe imiphumela engcono kakhulu ekusebenziseni okusebenzayo. Ngokuthuthuka komnotho kanye nokuthuthuka kobuchwepheshe, imboni yamapayipi ensimbi izoqhubeka nokukhula futhi ihlangabezane nesidingo samapayipi ensimbi emikhakheni ehlukahlukene. Asibheke ngabomvu imboni yamapayipi ensimbi idale ikusasa elingcono ekuthuthukisweni okuzayo!
