Monel K500 N05500 Amapayipi anama-Flanges

Ukuphikiswa kokugqwala kwe-monel K-500 ngokufanayo kuyafana no-Alloy 400, ngaphandle kwalokho esimweni esinzima sonyaka, i-Alloy K-500 inokuthambekela okukhulu ekucindezelekeni kwezindawo ezithile. I-Monel K-500 itholakale ukuthi ingamelana neminyaka eminingi kagesi.

Izidingo zeklayenti¡. Futhi singanikeza okususwayo kokusebenza okuqukethwe okuqukethwe okuqukethwe, kufaka phakathi amamojula wokusika amapayipi, ukubheja, ukuhlangana futhi

I-Incons 718 iqukethe ngokuyinhloko i-nickel (52%). Izakhi zezabelo zifaka i-iron (19%), i-chromium (18%), i-niobium + tantalum (5%), i-aluminium (0.5%), ngaphezu kwezinye izindlela zokulandela umkhondo njengeBaron, iCobalt, i-MANnganese kanye ne-Silicon.

Ezinye izindawo ezithandwayo ze-nickel-chromium ziseminyakeni evulwe ngokwanele ngokungezwa kwe-aluminium ne-titanium.

Njengo-Alloy omelana nokonakala, i-monel 400 ingamelana nezinga lokushisa eliphakeme le-Steams ezindaweni ezisheshayo ezihamba nge-brackish

Lokhu kuxhumana kufakwa ngaphakathi kwezindonga zikakhonkolo ngaphambi kokuthululwa kokhonkolo. Lolu hlelo kumele luhambisane kahle ngaphambi kokuthulula ukhonkolo ngoba ludinga ukumelana nesisindo namandla wesakhiwo.

Njengokuqala kokukhiqiza, zonke izinto kufanele zimakwe ukuze zikhulise ukubonwa kwezinto zokwakha. Umsebenzi wokumaka ungaqaliswa ngenxa yenombolo ethile yezakhi. Ngaphezu kwalokho, zonke izilinganiso zepayipi amapayipi kumele zikubekele zona. Ukulandelwa kwezakhi akumele kungcolise impahla ngaphandle kokulandela kungasabela ngezinto ezibonakalayo futhi lokhu kungadala izinkinga ezisusiwe.

Abahlinzeki be-Hastelloy B3 nabakhiqizi be-hasteloy B3 bangafinyelelwa kulo lonke izwe.

Enye yezinto ezehlukanisa ukwahlukanisa kwe-Incon 718¡¯s ukwakheka kwe-niobium ukuvumela ubusuku obuvumayo obuvumela ukuhlanganisa nokushiswa ngaphandle kokuqina kokushisa nokupholisa.

Hastelloy C276 2.4819 I-alloy ehlukahlukene kakhulu yokumelana ne-alloy etholakalayo yamapayipi atholakalayo

Ukuqina kwensimbi kungenye yezinzuzo ezinhle kakhulu zezinhlelo zepayipi. Kuqinile futhi kungamelana nezingcindezi, amazinga okushisa, ukushaqeka okusindayo, nokudlidliza. Iphinde ibe nokuguquguquka okuhlukile okunikezela ukunwetshwa okulula.

Insimbi yebanga le-304 ngokuvamile libhekwa njengensimbi evame kakhulu ye-auntenitic.

? Ukuqukethwe okuphansi kwekhabhoni ye-alloy 317l kukuvumela ukuthi kufakwe i-weld ngaphandle kokugqwala okuvela ekugxoliseni kwe-chromium carbide ukukwenza kube lula ukusetha isehlakalo se-as-welded.

Amapayipi ensimbi abuye abhekiswe njengezakhi ezenziwa kabusha zohlelo lwamapulangwe anjengamapayipi, ama-flanges kanye nokufakwa kwamapayipi, futhi afakwa ngesikhathi sokuthuthuka ngaphambi kokuwathumela ekwenzeni.

I-Hastelloy C276 ayithambekele ekutholeni imingcele yokusanhlamvu kunesimo se-welded futhi ngakho-ke ilungele izinhlelo eziningi zamakhemikhali.

Ngakho-ke irediyo ekhethiwe ye-elbow ingabaluleka kakhulu. Olunye uhlobo lwe-elbows lunciphisa ama-elbows. Kulolu hlobo lwe-elbows, ubukhulu bemisebe ye-Centre-Line Radius ilingana nengxenye yosayizi ophakeme wokuphela okukhulu. Ukunciphisa ama-elbows, futhi, gcina ushintsho lwe-90¡Ã flu flow ohlelweni lwepayipi. Ngaphezu kwalokho, ushintsho olungu-180¡Ã0Flow lungagcinwa ngokusebenzisa uhlobo oluthile lokunciphisa i-elbow ebizwa nge-¡®return bends.

Isetshenziselwa izakhi ezidinga ukuvezwa kwamanzi olwandle kanye nengcindezi ephezulu yemishini.

I-316l, nokho, ukukhetha okungcono kwephrojekthi edinga ukufudumala okuningi ngoba i-316 itholakala kalula ekuwohlokeni kwamandla ku-316L (ukugqwala ngaphakathi kweWeld).

Le alloy lensimbi ye-nickel isetshenziswe kalula futhi ingahle ifakwe kunoma yisiphi isimo se-annealed noma semvula (yobudala).

Imishini yokucubungula eshisayo ezinhlathini zezimboni, ezinjengamabhasikidi, amathreyi, nokulungiswa. Ngokucutshungulwa kwamakhemikhali noma kwe-petrochemical kusetshenziselwa ukushintshaniswa kokushisa nezinhlelo zamapayipi kuma-nitric acid media, ikakhulukazi lapho ukumelana nokuqhekeka kwe-chloride ukuxabana kokuqhekeka.

Ngakho-ke irediyo ekhethiwe ye-elbow ingabaluleka kakhulu. Olunye uhlobo lwe-elbows lunciphisa ama-elbows. Kulolu hlobo lwe-elbows, ubukhulu bemisebe ye-Centre-Line Radius ilingana nengxenye yosayizi ophakeme wokuphela okukhulu.

Ngaphezu kwalokho, ushintsho olungu-180¡Ã0Flow lungagcinwa ngokusebenzisa uhlobo oluthile lokunciphisa i-elbow ebizwa nge-¡®return bends.

Incoloy 800 N08800 Pipe Pipe Spools Ukumelana Okuhle Kokugqwala ezindaweni ezahlukahlukene ezilimazayo

Lezi zinenzuzo ye-nickel kanye ne-molybdenum enikeza ukumelana nezimo ezinciphisa kakhulu. Ukumelana ne-oxidation kuphakame kakhulu kulezi zinto zokwakha ngenxa yokungezwa kokuqukethwe kwe-chromium.

Ukucaciswa kwezinhlobo ze-Flange kwenziwa nge-ASME B16.5 Standards. Ngakho-ke ama-flanges ahlukaniswa ngokuthi; Intamo ye-Weld, ukushelela, iSocket Weld, i-Lap-Joint-Joint. Ama-flanges e-weld entamo kulula ukubona. Ukuqhuma kwe-cylindrical okunokwanda kancane kancane kuxhumeke engxenyeni eyinhloko eyize.

I-alloy yenziwa ngo-50-55% nickel + cobalt (nge-cobalt linqunyelwe ku-1% max) kanye ne-17-2% chromium.

I-Incoloy 800 N08800 Pipe Spools enezengezo ezifana ne-molybdenum Copper nitrogen kanye ne-silicon

nickel alloy hastelloy B2 2.4617 Ukumelana nepayipi kwe-Preak kuma-Sulfuric kanye ne-Acetic nePhosphoric Acids

Le alloy iyamelana nokwakhiwa kwemingcele yokusanhlamvu ethambekele endaweni ephazamiseka ukushisa, ngaleyo ndlela okwenza kube lulungele izinhlelo eziningi zenqubo yamakhemikhali esimweni se-welded.

I-Monel K500 iyi-alloy enobunzima be-nickel-Copper ehlanganisa ukumelana nokugqwala kwama-alloy 400 ngokukhathala okuphezulu kokugqwala kwamandla nokuphikiswa komoya.

Zisetshenziselwa insiza yokushisa ephezulu, lapho kudingeka khona i-oxidation kanye ne-carburburation. Ngezakhiwo ezinhle kakhulu zokucindezela kwengcindezi, noma insiza yomkhumbi yengcindezi engenhla kwe-815¡Ãc, incoloy 800h noma incoloy 800ht kufanele isetshenziswe.

Le ncwadi ye-nickel imelana ikakhulukazi nama-hydrochlecloric kanye nama-hydrofluoric acid lapho e-de-aerated. Njengoba kulindeleke ukuthi kulindelwe okuqukethwe kwethusi okuphezulu, i-Alloy 400 ihlaselwa ngokushesha yi-nitric acid kanye ne-ammonia systems.
