Izithombe zokuhlola ngaphambi kokuthumela ziphakamise ubuso be-flange
Ezicelo ezikhethekile zezindiza, i-chromium kanye ne-nickel hlobo insimbi engenacala isetshenziswa ngenxa yokuvimbela kwabo nokumelana nokugqwala. Kutholakale kuzinhlelo zokusebenza ezidinga amandla aphezulu, amashubhu we-stacken ensimbi angasebenza kahle angenziwa lukhuni noma ashiswe, yize izingcezu ezilukhuni, yize izingcezu ezilondolozwe ezisebenza kanzima kufanele zisetshenziswe nezinhlobo ezithile zezinto ezilimazayo. Izinhlobo zekhabhoni ephansi zensimbi engenasici ziyinketho ejwayelekile yezingxenye ezinama-welded.
Ipayipi lensimbi engama-316 elingagqwali liye laba yinto ebaluleke kakhulu emkhakheni wezimboni. Le alloy yensimbi ne-chrome yamukelwa ngokumelana kwayo okuphezulu ekugqwaneni, kanye nokuqina kwawo. 316 I-tubing yensimbi engagqwali ingakhiqizwa kumashubhu angenamthungo nama-welded ukuze ahlangabezane nezidingo zamakhasimende athile.
I-Al6XN iyinsimbi e-superAustonitic engenacala ngokumelana okuvelele kokuphamba kwe-chloride, ukugqwala kwe-crevice kanye nokuqhekeka kokugqwala kwengcindezelo. I-Al6xn ingu-Aloy ayi-6 olwenzelwe futhi asetshenziswa ezindaweni ezinolaka kakhulu. Ine-nickel ephezulu (24%), i-molybdenum (6.3%), i-nitrogen kanye nokuqukethwe kwe-chromium okunikeza ukumelana kahle nokuqhekeka kokugqwala kwe-chloride, i-chloride ukumelana, kanye nokuphikiswa okujwayelekile kokugqwala. I-Al6xn isetshenziselwa ikakhulukazi ukumelana nokugqwala kwayo okuthuthukile kanye ne-crevice in clorides. Kuyinsimbi enobunzima futhi engakhathali.
I-Tight yethu 2 Flange, I-Carbon Steel A694 F60 F65 FROCE WELDB ELB, ASTM A182 S32750 Stud Bolt yinoveli kubuchwepheshe kanye nengqondo ngesakhiwo. Bathengisa kahle ekhaya nakwamanye amazwe futhi bamukelwa iningi labasebenzisi. Ngokuqongelela izenzo ezinhle, sethemba ukufaka isandla ekukhuleni okuzinzile kwendlela entsha yokuthuthuka yokugcina imvelo, okufaka isandla emphakathini nokubaluleka komthombo oqinile womuntu. Njengamanje, senza imizamo eminingi yokuhlanganisa kokujwayelekile, ngethemba lokuthi ukwakha iphethini entsha yentuthuko yenkampani ngendlela entsha. Ngenkathi ubamba umkhiqizo ongumgogodla wobuchwepheshe, inkampani ikhokha ukunakwa okwengeziwe ekuhlinzekeni amakhasimende ngemikhiqizo nezinsizakalo ezingcono. Imishini esezingeni eliphakeme, ukwakhiwa okuhle kobuchwepheshe, ubuchwepheshe obuhle kakhulu bokukhiqiza, uhlelo lokuqinisekisa ikhwalithi ephelele kanye nensizakalo yezentengiso yesikhathi ngezithembiso zethu kuwo wonke amakhasimende.
Cishe i-304 304L 304h Pipe, ipayipi lensimbi engagqwali ngumkhiqizo olula kunabo bonke futhi usekelwa ukwakheka ngenxa yokusebenza kwayo okuhlukahlukene. Lolu hlobo lwebanga luyalelwe ngabathengi. Inamandla okuqhathaniswa, ukwakhiwa komthungo kanye nemishini. Insimbi engenasici inezakhiwo eziningi ezizuzisayo njengokumelana nokugqwala, i-decticity, amandla aphezulu, njll. Inobuhlakani obuhle bokushisa nobukagesi.
Indlela yokumaka yensimbi engagqwali i-American Iron ne-Institute yensimbi isebenzisa izinombolo ezintathu ukumaka amamaki ajwayelekile ahlukahlukene wensimbi engenacala. Phakathi kwazo: ¢ Ama-Steautusnitic ama-stainless angenazimpawu amakwe ngezinombolo ze-200 neze-300. Isibonelo, ezinye izinsimbi ezijwayelekile ze-auntenitic ezingenasici zimakwe ngo-302, 304, 316 no-310, ¢ úferritic kanye ne-martensitic ama-sterments anyatheli asetshenziswa inani lochungechunge lwe-400 limelelwa. Ng ûferritic insimbi engagqwali imakwe ngo-430 no-446, insimbi engenacala elingenacala imakwe ngo-410, 420 no-440c, i-duplex (i-auceple-ferrite), ¢ Insimbi evuthayo yensimbi engenasici kanye nama-alloys aphansi avame ukuba nelungelo lobunikazi noma afakwe uphawu
I-317l ayizibuthe esimweni esiveziwe se-annealed kodwa ingahle ibe yizinkazimu-kancanyana ngenxa ye-welding.Fittings enikelwe ngaphansi kwalolu hlelo luzohlolwa ngokubonakalayo kokuhlelwa komhlaba, amasheke angaphezulu, kanye namamaki omshini.
Ukucaciswa kwe-UNS S31803 (ASTM F51) kudluliselwe kakhulu yi-UNS S32205 (1.4462, ASTM F60). Lokhu kukhombisa isifiso sabo sokwandisa izakhiwo zokugqwala kwe-alloy, ngenxa yokuthuthukiswa kwenqubo yokwenza insimbi ye-AOD, okuvumela ukulawulwa okunzima kokwakheka. Ngaphezu kwalokho, kuvumela ukuthonya izinga lesengezo le-nitrogen kunokuba nje likhona njengento yangemuva. Ngakho-ke, amamaki aphezulu aphezulu kakhulu afuna ukukhulisa okuqukethwe kwe-chromium (CR), i-molybdenum (mo) ne-nitrogen (n).
Njengomunye wabakhiqizi abaholayo eChina, sikwamukela ngemfudumalo ukuthi uthenge ikhoyili yethu ye-309 yensimbi engagqwali. Ifektri yethu nayo yamukela imiyalo eyenziwe ngokwezifiso. Sicela ukhululeke ukujabulela intengo yethu yokuncintisana kanye nensizakalo enhle kakhulu.
