I-2022 ishushu ithengisa i-dupplex phumela

Sinikezela nge-tees enje nge-ANI B16.9 Alloty Alt H18020 ngoomatshini oLungileyo kwaye banokupeyinta ngokugqwetha ngokugqitha kumgangatho womhlaba wabo njengoko kufuneka. I-ASTM B366 Alloty DON 2.460 I-Weldings Stored Syttings Spires, iNdawo yokuHamba, ukutya kunye neziselo. Sikwangumthumeli ngaphandle i-ASTM SB366 Alloty ezingama-20 ezingenamthungo zokusetyenziswa okungapheliyo kwii-rigs zeoyile.

I-Stainess Steeety Sciets ihlelwe ngokweentlobo ezintathu zezikhongozeli ezinokuthi zakhiwe kwi: imibhobho, imibhobho neempuphu. Umbhobho ngumngxunya wetyhubhu ye-homogeneous ye-homogeneneous enengqondi ethile kunye nokuqina. Kumzi-mveliso, imibhobho kunye nemibhobho zihlala zifana, umahluko kuphela yindlela ubude babo. Ukungcungcutheka kunye nezixhobo zihlala ziphawuleka ngokuchaneka kunokuba zizenzele imilinganiselo.

I-B16.11 ifanelwe ngokufanelekileyo, isokisi ye-welting kunye ne-ATTM B366 I-ATTM B366 I-ACTE I-Igness, Monel, i-Dotelloy kunye ne-Nickel Aflings esetyenziswe kwi-acidic kunye namanzi olwandle.

Cinga ngobulumko kwaye unxibelelane nathi njengoko sithumela ngaphandle le mveliso phesheya phesheya kwaye kuyo yonke indawo, siqhelene i-s32750 ye-S32750.

I-tee ilinganayo \ / I-tee ngqo ye-tee, indawo yokulinganisa yesebe iyafana nokubaleka, ngelixa kuncitshiswa i-tee, iziko lokuphela kwesebe lincinci kunenkqubo yokufaka.

Imoral 400 yenziwa nge-nickel kunye nobhedu kunye nezixhobo zokulandela umkhondo ezibandakanya i-iron, i-manganese, ikharbon, kunye nesilicon. Imodareyithi engama-400 inesifo inesidima esigqwesileyo nxamnye ne-Acids kunye ne-alkalis apho, ukuba nokungaxhaleli kakhulu.

Izixhobo zenziwe kwaye emva koko zifudumele kubushushu obuphezulu emva kokupholisa okukhawulezayo kufutshane nokupholisa emoyeni. Oku kuphola ngokukhawuleza kongezwa kumandla ama-stanes ongenasinqeli kunye ne-speefs yentsimbi kwaye kubenza bomelele kakhulu. I-SS 310S isetyenzisiwe kumashishini njengendlela yokusebenza kwamanzi aselwandle, izityalo ezinamandla ombane kunye nezityalo ezikwindawo ye-thermal amandla kunye nokufakelwa kwekhaya kakhulu. I-310s ss ye-Ws isetyenziswa kwiiklasi ezahlukeneyo zoxinzelelo zokuhlangabezana nemfuno yoxinzelelo lwesicelo.

IsiTshayina (Esenziwe lula)

I-Alloty 20 (Aloy 20) yi-Austitic esekwe i-Iron-Altithic Alloty equlethwe ukuxhathisa i-sulfuric sciasion. Inokuchasana ngokugqwesileyo kwimeko ye-sulfuric acid yosulelo; Inokungaxhathisa okuqatha kwi-phosphoric acid, i-nitric acid kunye ne-chloride fide, i-chloride yoxinzelelo i-comrosion, imbiza i-corrosion kunye ne-creas. Ke ngoko, i-Alloty 20 inesabelo sokulwa, Inoluhlu olubanzi lwezicelo: ezinje: ikhemikhali, ukutya, iyeza, ukuveliswa kwamandla kunye nemizi-mveliso yeplastiki iya kuyisebenzisa. Ukuxhathisa ekupheliseni i-colososion kunye ne-chloride yosulelo, uxinzelelo lweengxaki zokuqhekeza, njl njl. I-Aloby 20 ihlala isetyenziswa.

Abacimisi be-SD yenzelwe ukulinganisa ukunganyangeki ekupheliseni, ukutyeshelwa kwengqondo, i-erosion-ukhuko, i-SCC, amandla aphezulu kunye namandla aphezulu eldice. Umnqamlezo we-SD udibanisa ubude, amandla okuphumelela okuphezulu kunye nokunganyangeki kwendlela yemozulu.

I-ASTM B i-366 i-Dotelloy C276 i-Weldat ye-Welled isetyenziselwa uqhagamshelo lwesebe le-Welding apho umbhobho \ / inkonzo ephezulu yoxinzelelo. Yenzelwe ukunciphisa uxinzelelo loxinzelelo kwaye ibonelele ngokuqinisiweyo.

I-Alloy 410, ibalulekile, injongo ngokubanzi, injongo ngokubanzi Martines Staines ezisetyenziselwa uxinzelelo olukhulu kakhulu kwaye libonelela ngokuchaseneyo nokunganyangeki kwengqondo, kunye nobunzima kunye nobunzima. I-Alloy 410, iqulethe ubuncinci be-11 .5% yentsimbi enobuncinci bokubonisa iipropathi zokunganyangeki kwi-atticals, i-Steam, kunye ne-stiam yeefildicals zemichiza.

Imibhobho yensimbi inokuqhekezwa ngesiseko sesicelo sayo. Imisebenzi yesiqhelo yemibhobho yentsimbi ikwindawo yemibhobho yamanzi, imizila yamanzi emizi-mveliso, imigca ye-oyile, imizila ye-oyile, imizi ye-chibe yegesi, imizi-mveliso ye-chibe, amashishini okwakha nezinye iinjongo.

I-ASTM B366 AN08800 N06625 N0800 N06400 N0890 18030310303

I-MSS-SP43 ye-radius ende, ngokuthe ngqo kwaye inciphise i-tees ye-tees, i-gesing, i-CAPS, i-radius ye-oncents, i-\ / 2 "-sch5s-schxxs

I-317l ayingeyonto ye-agnetic kwimo ye-onnetic kodwa inokuba yimagnethi kancinci njengesiphumo se-welding.

I-Alll I-ALTEY nayo ikwanazo iipropathi ezigqwesileyo kwaye idibene nenqanaba elifanelekileyo lamandla aphezulu kunye noomatshini olungileyo.

I-Stainis Poipe Speef isetyenziselwa ukudibanisa imibhobho emi-2 njengoko inombhobho ofanelekileyo kwisiphelo esinye okanye zombini. I-tee yentsimbi engenasitayile inamandla e-theile anama-515 MPA kunye nesivuno sama-205 MPA.

Ngokubanzi, ukuxhathisa i-monel K500 kwisisombululo esiqinileyo ngokusisiseko njengemo yemodareyitha engama-400 Alloty, ngoko ke iDatha yokunganyangeki kwemollow 400 inokusetyenziswa kwimogaqo ye-MOLT500 Alloty. Ngenxa yenqanaba layo lokungazicingela eliphantsi kunye namandla aphezulu okuqukuqela amanzi olwandle, i-alloy ilungele ngokukodwa ekwenzeni i-cerosion ye-cerosifor ye-cerriigugatugal engaqhelekanga.

Ibanga le-310s yentsimbi engenasitali ye-Woolt iqulathe i-carbon ephantsi, i-NECTEL kunye ne-chromium kunye ne-chromium kunye neebhasikiti ezihambayo, iibhasikiti zonyango, i-fesser, elunxwemeni njl njl.

Ukongeza ekunikezeleni ukumelana nokunganyangeki kwi-insosion engaphakathi, i-317l yentsimbi yentsimbi ibonelela ngoxinzelelo oluphezulu, ukugcoba kunye namandla amanqam okuphakathi, xa kuthelekiswa namanqanaba ensizi engenasiseko. Umxholo wekhabhoni esezantsi kwizinto eziveliswa kule Ngqekembe engenantsingiselo yi-alloy ibambene nokuva okubandakanya ubushushu, njengokwezinye iinkqubo ze-ilding.

I-MSSS-SP75 i-radius ende, i-3r ellows, iitayile ezithe tye, ukunciphisa i-Tees, i-COPS, ubungakanani be-SCH18S-schxxs

Malunga namandla aphezulu kunye nobunzima obugqwesileyo, ubuchule bokunganyangeki uCrasions Ukunganyangeki kunye namandla aphezulu baboniswa bubume bayo apho kudityaniswe khona ngokuchasene nokuchasana nokuchasana nokuxhaphaza. I-S31803 yezixhobo zombhobho ye-S31803 ineemfuno eziphezulu apho imfuno yokunganyangeki kakuhle kunye namandla amahle kuyafuneka. Ngokuthengiswa kwe-oxiding, acidic kunye ne-caustic, ibonisa ukunganyangeki okuhle ekuphenduleni nasekucutha i-crevice.

I-Deplex Steel 2101 I-Wipe ye-Weld Wile, eyeyona isetyenziswayo ye-duppex (i-ferricuc kunye ne-Austeritic) ye-Altional Altings ye-Altional. I-300 degree C.

Ukuze udlulisele umbhobho, kuyimfuneko ukususa i-hose ethe tye ngombhobho. Xa usebenzisa imibhobho eyahlukeneyo, kufuneka isetyenziswe ngemibhobho eyahlukeneyo. Xa kusetyenziswa umbhobho, i-elbow kufuneka isetyenziselwe ukutshintsha ubungakanani bombhobho. Xa ukubhabha, umbhobho weendlela ezintathu kusetyenziswa xa i-pipeling eyahlukeneyo ye-pipeling kunye nokwanda kokuhamba kwexesha elide kunye nokwandiswa komgangatho obandayo kunye nolwandiso olubi kakhulu kunye nolwandiso olubandayo olusetyenziselwa ukunxibelelana nombhobho. , Ekuqhagamsheleni nezixhobo ezahlukeneyo, kukho i-quadriday kunye neeplagi zesigaba sesixhobo.

I-Deplex 31803 \ / 32205 i-Fittings zibonelela ngokuchaseneyo kakhulu kwi-Crevice kunye ne-chloride. Oku kuxhathisa kubalulekile kwiinkonzo ezinjenge-brine, iinkqubo zokulawula iinkqubo, iindawo zaselwandle, kunye nezicelo ezithile zokutya.

Ukuxhathisa kwe-corrosion yale alloy yedwa kwenza i-dupplex yentsimbi yentsimbi ye-pubilex yentsimbi ye-pie yentsimbi engcono yezicelo ezinzima. Amashishini anje ngeoyile kunye negesi kunye ne-petrochemicals ziimeko eziphezulu. Lo mveliso ufuna iimveliso ezinje nge-ASTM AP315 ayingaphezulu kwe-S31803 ye-elbows engahambelani kuphela kodwa enesibindi.

I-ASME B16.9 I-VIDS ende, i-radius ende, i-radius ye-radius, i-radius ye-radius, i-thering, i-feeds, i-\ / 28-sch5s-schxxs

I-hastelloy X igobho ye-hadnd sisiseko se-nickel seckel esinamagqabi aphezulu amaqondo obushushu aphezulu kunye nokunganyangeki kwe-oxidation. Zonke iifom zemveliso zigqibelele ngokwendlela yokwakha kunye ne-welding.

I-B16.11 ifanelwe ngokufanelekileyo, isokisi ye-welting kunye ne-ATTM B366 I-ATTM B366 I-ACTE I-Igness, Monel, i-Dotelloy kunye ne-Nickel Aflings esetyenziswe kwi-acidic kunye namanzi olwandle.

Cinga ngobulumko kwaye unxibelelane nathi njengoko sithumela ngaphandle le mveliso phesheya phesheya kwaye kuyo yonke indawo, siqhelene i-s32750 ye-S32750.

I-al-6xnalloy (i-n08367) yikhabhoni ephantsi, ukucoceka okuphezulu, i-nitrogen enobunkunkqele "i-super-austy" ye-alfacitic "ayinamafutha angenasiseko. I-al-6xn alloty yenzelwe ukuba ibe yinto emazantsi elwandle kwaye ibonakaliswe ukuba inganyangeki kuluhlu olubanzi lweendawo ezinobubanzi kakhulu. Amandla aphezulu kunye nokunganyangeki kwe-Al6xn Alloty yenza ukuba ukhetho olungcono kunakwizistim eziqhelekileyo ze-humex kunye nendlela efanelekileyo yexabiso le-nickel yendlela ebiza ngayo, ukuba iphantsi kwexabiso eliphezulu.
