Uyilo lwezinto ezintsha: Uhlalutyo lokusebenza kweeFlange zeNtsimbi engagqwaliyo kwiindawo ezidlakadlaka
Iinkcukacha zeMveliso eziphambili:
-
Ulwakhiwo lwe-alloy:Izinto eziphambili zentsimbi engagqwaliyo iiflange ziyintsimbi engagqwaliyo engama-304 okanye engama-316. Eyokuqala ine-18% ye-chromium kunye ne-8% ye-nickel, efanelekileyo kwiindawo ezingathathi cala; eyesibini yongeza i-2-3% ye-molybdenum, ephucula ukumelana nokugqwala kwe-chloride ion.
-
Iipropati zoomatshini:Ngokwemigangatho ye-ASTM A182, amandla okutsalwa kweeflange zentsimbi engagqwaliyo anokufikelela kwi-500-600 MPa, aphezulu kakhulu kune-400 MPa ye Intsimbi yeCarbonItshathi elandelayo ibonisa uthelekiso lwamandla okutsalwa kwezinto zeflange eziqhelekileyo (iyunithi: MPa), igxininisa ukusebenza okulungeleleneyo kwentsimbi engagqwaliyo.
-
Iindlela zoQhagamshelo:Iiflange zentsimbi engagqwaliyo zixhasa iindlela ezahlukeneyo zoqhagamshelo ezifana nokuwelda kunye nokubopha, okuqinisekisa ukuthembeka kokutywina.
-
Iintlobo zezinto ezikhethekileyo:Olu didi lukwabandakanya iintsimbi ezingenasici zeDuplex kunye neSuper Duplex, ezisebenza kakuhle kwiindawo ezine-chloride ephezulu, zimelana nokuqhekeka kwemingxuma kunye nokuqhekeka koxinzelelo.
-
Indlela Yokumelana Nokugqwala:Ukumelana nokugqwala kwentsimbi engagqwali kuvela kumaleko we-chromium oxide owakheka phezu komphezulu. Lo maleko uyazilungisa ngokwawo, ubonelela ngokhuseleko lwexesha elide.
-
Ukusebenza kwiindawo ezineasidi:Intsimbi engagqwaliyo inika ukumelana okuhle kwiiasidi ezininzi, kuxhomekeke kuxinzelelo kunye nohlobo. Umzekelo, kwi-asidi ye-sulfuric exineneyo, izinga lokugqwala linokuba liphantsi njengee-micrometer ngonyaka.
-
Ukucubungula:Ngexesha lokwenziwa, iiflange zentsimbi engagqwaliyo zihlala ziphathwa ngobushushu ukuze kuphuculwe isakhiwo sekristale kwaye kuphuculwe ukuqina. Emva kokudityaniswa, zihlala zicoliwe kwaye zingasetyenziswa ukuze kuphuculwe umaleko womphezulu okhuselayo.
Itshathi elandelayo ithelekisa amandla okutsalwa (iyunithi: MPa) ye-common iflengi izixhobo, ezibonisa ukusebenza okulungeleleneyo kwentsimbi engagqwaliyo:
Idatha ekumfanekiso ibonisa ukuba intsimbi engagqwaliyo inexabiso lamandla eliyi-515 MPa, nto leyo ebangela ukuba izinga lokuguquguquka libe yi-0.2% kuphela xa kushushu kakhulu kwaye kucinezelwe, ngelixa i-PVC, enamandla angama-50 MPa kuphela, ifanelekile kwiimeko ezinoxinzelelo oluphantsi.
Idatha yovavanyo ibonisa ukuba kwindawo yokutshiza ityuwa, izinga lokugqwala kweeflange zentsimbi engagqwaliyo liyi-0.01 mm ngonyaka kuphela, eliphantsi ngokuphindwe kalishumi kunezinga lentsimbi yekhabhoni eliyi-0.1 mm ngonyaka, nto leyo ekhokelela ekwandeni ngokuphindwe kalishumi kobomi benkonzo. Ngokukodwa:
-
304 Intsimbi Engagqwaliyoinokumelana neendawo ezine-chloride ion concentrations ukuya kuthi ga kwi-200 PPM.
-
316 Intsimbi Engagqwaliyoinika ukumelana okuphezulu nangakumbi, nto leyo enciphisa kakhulu amazinga okungaphumeleli okunxulumene nokugqwala kubunjineli bezolwandle.
Kwizicelo ezifana nezityalo ze-sulfuric acid, intsimbi engagqwaliyo igcina ukumelana okuhle nokugqwala nokuba kubushushu obuphezulu obuyi-200°C. Ngaphezu koko, kwishishini lamayeza, iiflange zentsimbi engagqwaliyo zifuna ukugqitywa okuphezulu, okuhlala kungaphantsi kwe-Ra 0.8μm, ukuthintela ukukhula kwebhaktheriya.
Iphepha leDatha yokuSebenza kwezinto
| Uhlobo lwezinto | Amandla okuThamba (MPa) | Ukumelana nokugqwala | Uluhlu lobushushu (°C) | Izicelo eziqhelekileyo |
| Intsimbi yeCarbon | 400 | Iphakathi | -29 ukuya ku-425 | Iipayipi eziQhelekileyo |
| Yenziwe ngentsimbi eshayinayo | 515 | Igqwesile | -196 ukuya ku-816 | Iikhemikhali, zaselwandle |
| Intsimbi ye-alloy | 600 | Kulungile | -46 ukuya ku-540 | Ubushushu obuphezulu, Uxinzelelo oluphezulu |
| I-PVC | 50 | Igqwesile | 0 ukuya kuma-60 | Iindawo eziGcolisayo eziphantsi koxinzelelo |
| Intsimbi yobhedu | 300 | Kulungile | -100 ukuya kuma-200 | Uqhagamshelo lokuhombisa |
Ngokusekelwe kwidatha enikiweyo, iiflange zentsimbi engagqwaliyo ziye zaba lolona khetho lukhethwayo kwiindawo ezirhabaxa, nto leyo eqhuba ukukhula kwesabelo semarike. Izifundo ezisebenzisekayo zibonisa ukusebenza kwazo:
-
Kwisityalo seekhemikhali, ubomi benkonzo yezixhobo bandiswa yi Iminyaka emi-5–10emva kokwamkela iiflange zentsimbi engagqwali ezingama-316, iindleko zokulungisa zincitshiswe kakhulu.
-
Kwiqonga lokugrumba eliselunxwemeni, ukusetyenziswa intsimbi engenasici kabinikubangele ukuba Ukunciphisa ngama-30%kwiintsilelo ezinxulumene nokugqwala.
Lo mzobo ulandelayo ubonisa ezi nzuzo:
Ukubonelela ngomfanekiso oneenkcukacha ngakumbi wesakhiwo sangaphakathi kunye neengqimba zezinto zeflange yentsimbi engagqwali, olu cwangciso longezelelweyo lwemveliso lugxininisa ukwakheka kwe-alloy kunye nonyango lomphezulu:
Uphuhliso lwexesha elizayo lweeflange zentsimbi engagqwaliyo lubandakanya iteknoloji yokwenza i-nano-coating yokuphucula ngakumbi ukumelana nokugqwala, kunye nokwamkelwa kwezinto ezisetyenzisiweyo kwimveliso ezinzileyo ukunciphisa impembelelo yokusingqongileyo.
