Imigoqo yensimbi yekhabhoni kanye nezinduku

Kodwa-ke, amandla abo okukhathala aphakeme kunama-flanges ashelelayo. Inkinga enkulu yeSocker Weld Flanges yingozi yokugqwala. Igebe phakathi kwe-flange nokufaneleka noma ipayipi kufanele ligcinwe ngaphambi kokushiswa. Uketshezi olulimazayo noma umswakama lungathola kulezi zindawo zokukhosela. Ngakho-ke, lesi sibonisi esinamanzi aqinile singadala ukugqwala emzimbeni.

I-Spool Spool yinto etholwayo yezakhi zamapayipi, eziqaliswa kabusha

Amapayipi angama-304 enziwe ngensimbi engama-304 engagqwali, impahla ejwayelekile futhi ethandwayo kuzinhlelo eziningi zezimboni ezidinga ukumelana nokugqwala kanye noximation. Lawa mapayipi amapayipi e-S30400 ahlanganiswe asebenzisa imishini ekhethekile nezinqubo, eziqinisekisa ukuthi zinembe kakhulu futhi zithembekile.

I-904L I-Steressless yensimbi ayifani nanoma iyiphi enye insimbi. Ngenxa yamanani angeziwe angeziwe we-chromium, i-molybdenum, i-nickel ne-zethusi, insimbi engu-904l ifaka ukumelana okuphezulu kokugqwala, ukugqwala kanye nama-acid.

Izingxenye ezihlangene kukhona ukushisa kuphathwe ngenhloso yokunciphisa izingcindezi zangaphakathi ezibangelwa. Inqubo yokwelashwa kokushisa yenziwa ngokusho kwe-ASME B31.3 Amazinga. Ngemuva kwalokho, amapayipi amapayipi kufanele apendwe ukuze avikelwe izindawo ezivela kunoma yiluphi ubungozi boxolo.

I-316l nayo yensimbi enhle engabi nesiqhingi ekushiseni okuphezulu, ukusetshenziswa okuphezulu kokugqwala, yingakho kudumile kakhulu ukusetshenziswa ekwakhiweni kwezokwakha nasezandleni zasolwandle.

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.

I-InColel iyi-superelloy eyenziwe ngokugxila okuphezulu kwe-nickel, i-chromium kanye ne-molybdenum. I-Incons 625 imelana kakhulu nemidiya ye-Contosive and oxidizing ezindaweni ezahlukahlukene. Lezi ze-alloys zinomkhondo omuhle kakhulu nokulukulela okuhle. Zingafakwa kalula futhi zimelana ne-post-weld carburhation noma ukusanhlamvu.

Ama-elbows ngokuvamile asetshenziselwa ushintsho ekuqondisweni kokugeleza. Izinhlelo ezijwayelekile ze-elbow zingashintsha i-angle yokugeleza ngo-180¡Ã, 90¡Ã noma i-45¡Ã noma i-45¡Ã noma i-45¡Ã. Uhlelo lwe-180¡Ã elbow lubizwa nangokuthi ¡® ®return bend¡¯. Amasistimu we-elbow angahlukaniswa abe ngamaqembu amabili ayi-butt weld elbows kanye nokunciphisa ama-elbows. I-butt-welded elbows iyizakhi ezivame kakhulu futhi ezifiselekayo.

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

Okuqukethwe okuphezulu kwe-chromium kukhuthaza futhi kugcinwe ifilimu nje evikela impahla ezindaweni eziningi ezilonakalisayo.

Hastelloy b3 preatparfication amapayipi ngama-flanges nakancane ukugxila kanye namazinga okushisa

Amapuleti ensimbi engagqwali namashidi namakhoyili

Alloy 347 (uns s34700) nguColumbium waqinisa ipuleti yensimbi engenacala engenacala ngokumelana kahle nokuphikiswa okujwayelekile kanye nokuphikiswa okungcono ezimweni eziqinile ze-oxidizing eziqinile kune-321 (uns s32100).

Inani lama-welds ku-spool kumele ligcinwe ukubala okuncane. Ubukhulu besikhala phakathi kwezindawo eziphakathi nendawo kanye nemigqa yesikhungo akumele ibe mikhulu kuneziphindwe kane udonga lwepayipi noma efanele. Ngemuva kwama-welds amakhulu, ama-tacks welds kumele enziwe ngokunembile. Zonke ama-welds e-spools kumele zisetshenziswe ngokuya ngokucaciswa kwenqubo ye-welding efanele (i-WPS). Ngemuva kokuthi inqubo ye-welding yenziwe, ukulawulwa kwekhwalithi kwezakhi kwenziwa ngochwepheshe.

Izinga eliphansi lokugqwala ngamanzi aqheleleni ageleza ngokushesha noma amanzi olwandle ahlanganiswe nokuphikiswa okuhle kakhulu ekuqhekekeni kwengcindezi kuma-frowwaters amaningi, kanye nokumelana kwawo ezinhlobonhlobo zezimo ezilonakalisayo eziholele ekusetshenzisweni kwalo ngokwanele kwezixazululo zasolwandle nezinye izixazululo ze-chloride.

Ukudalulwa okunjengalesi kuhlalwa njalo ngesikhathi sokwelashwa okuhlaselayo okuxhunyiwe nge-wacrication.

Amapayipi spools yizingxenye zangaphambi kokwakha kohlelo lwamapayipi. Amapayipi, ama-flanges, kanye nokufakelwa abizwa ngokuthi ama-Pipe Spools futhi akhiqizwa ngaphambi kokuthi asetshenziswe ohlelweni lwamapayipi.

I-Inxotemensi 718 2.4668 I-Pipe Peabrication ewusizo ebangeni eliwusizo emikhathini

Inokumelana okukhulu ekuqhekekeni kwengcindezi - ukuqhekeka kokugqwala nokukhonkotha. Hastelloy B-2? Futhi ifaka ukumelana ne-hydrochloric acid kuwo wonke amazinga okuhlala kanye namazinga okushisa.

I-Alloy C-276 ichazwa futhi njenge-Alloy C276, i-Inxote C76 noma i-Hastelloy C, okuyi-superlosiy enenhlanganisela ephelele ye-molybdenum, i-nickel ne-chromium. UTungsten ungeziwe, oklanyelwe ukuhlinzeka ngokumelana kahle nokugqwala okuphezulu ngisho nasezindaweni ezinokhahlo.

I-Alloy 317L inokuphikiswa okuhle kakhulu kokugqwala ngamakhemikhali ahlukahlukene. Imelana nokuhlaselwa ku-sulfuric acid, i-chlorine ye-acidic ne-phosphoric acid.

Amapayipi spools yizingxenye zangaphambi kokwakha kohlelo lwamapayipi. Amapayipi, ama-flanges, kanye nokufakelwa abizwa ngokuthi ama-Pipe Spools futhi akhiqizwa ngaphambi kokuthi asetshenziswe ohlelweni lwamapayipi.

Banokumelana okuhle nokuphikiswa kwe-oxidation. Ukuqiniswa kwama-alloys ama-super kwenziwa ngokuqina kwesixazululo esiqinile, ukusebenza ngamandla, nezindlela zokuqinisa zemvula.

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

Amapayipi amapayipi abunjwe ngaphambili ukwenza lula ukuhlanganisa ukusebenzisa ama-hoist, ama-gauges namanye amathuluzi okujoyina izingxenye. Amapayipi Spools ahlanganisa amapayipi amade ngama-flanges avela ekugcineni kwamapayipi amade ukuze agoqwena ngogesi ofanayo.

I-Alloy 600 \ I-Incontel 600 iyinhlanganisela ye-nickel chromium ne-iron enikeza impahla ejwayelekile embonini yamakhemikhali kanye nenjini yezimoto, injini ye-AERHO NE-AIRFrame. Ukwakheka okulawulwayo kwamakhemikhali kukhawulelwe ukusetshenziswa embonini yenuzi ukuqeda ubungozi bokuqhekeka kokuphazamiseka kokuqhekeka emanzini ahlanzeke kakhulu aqukethe ama-chloride ion.

I-Monel 400 isetshenziswa emikhunjini yenqubo, amapayipi okushisa okushisa, kanye nophethiloli namathangi okugcina amanzi akhona emkhakheni wasolwandle. Izakhiwo ezingezona ezikhazimulayo zalolu alloy zikwenza lulungele izimo ezinobungozi obukhulu kubamboni bezindawo eziqhumayo, amarokhethi kanye nezimboni zamaphepha.

Amapayipi angama-625 ama-225

Ukwakheka kwe-premium kokuqukethwe kwe-molybdenum kanye ne-nickel ye-C276 kusetshenziselwa ukwenza ama-alloys ensimbi ye-nickel. Kuyasiza ukumelana nokugqwala kwama-crorice kanye nokugqwala kokunciphisa izindawo. I-Chromium, ngakolunye uhlangothi, isetshenziselwa ukudlulisa ukumelana nemidiya exidizing.
