Iithegi zeMveliso

1. Isishwankathelo seMveliso – Yintoni iPipe yeMetallurgical Bonded Seamless Clad?

Aumbhobho onxibe i-metallurgical onamathelisiwe(ekwaziwa ngokuba yiityhubhu enxibe i-bimetal engenamthungookanyeUmbhobho ongenamthungo oxhonywe nge-CRA) yityhubhu edibeneyo esebenza kakhulu eyenziwe ngokudibanisa ngokusisigxina iumaleko wangaphakathi we-alloy enganyangekiyo nokugqwala (CRA)iya kuumaleko wangaphandle wekhabhoni okanye intsimbi ye-alloy enamandla aphezulu / ukumelana nobushushu obuphezulungenkqubo yokubopha ngesinyithi. Ngokungafaniyo nombhobho ofakwe ngoomatshini, la maleko mabini enza indawo yokusasazwa kwe-athomu kwisikali esiphakathi - okuphelisa ngokupheleleyo iingozi zokuwa kwe-liner, ukudumba, ukushwabana, okanye ukuqhekeka phantsi kokujikeleza kobushushu okanye ukutyhafa koxinzelelo.

Iindidi ezintathu zemibhobho ezifakwe kwimibuzo ekhankanyiweyo zimele iimeko ezintathu ezahlukeneyo zenkonzo ezifuna kakhulu:

● Umxube 1: P265GH + TP304L– Intsimbi engasemva: EN10216-2 P265GH (isitya soxinzelelo / umgangatho webhoyila). I-Inner cladding: Intsimbi engagqwaliyo engama-304L. Ifanelekile kwizicelo zobushushu obuphakathi (≤450°C) ezifana neepaneli zetyhubhu yebhoyila, ii-heat exchangers, kunye neepayipi zamakhemikhali apho kukho umphunga kunye nemidiya erhabaxa kancinci.

●Umxube 2: X10CrMoVNb9-1 + UNS N08028– Intsimbi engasemva: Intsimbi ye-T91 martensitic engangenisi ubushushu (X10CrMoVNb9-1). I-Inner cladding: I-Alloy 28 (UNS N08028, i-alloy ephezulu ye-Mo/Cu austenitic). Le ndibaniselwano iyamelana nayoamaqondo obushushu afikelela kwi-650°Cngelixa ixhathisa ukuhlaselwa kwe-chloride ephezulu, i-H₂S, kunye ne-organic acid. Isetyenziselwa amacandelo e-superheater/reheater kwiibhoyila ezibaluleke kakhulu nakwiiyunithi ze-petrochemical ezirhabaxa kakhulu.

●Umxube wesi-3: P265GH + UNS N08825– Intsimbi engasemva: P265GH. I-Inner cladding: Incoloy 825 (i-nickel iron chromium alloy eneMo, Cu, Ti). I-Incoloy 825 inika ukumelana okuhle kakhulu ne-oxidizing kunye ne-reducing acids, kwaye ifanelekile ngokukodwa kwi-Inkonzo ye-H₂S / CO₂ / i-high chloride sourukuhamba kweoyile negesi, imibhobho engaphantsi komhlaba, kunye nezixhobo zokutshintshiselana ubushushu ezinoxinzelelo oluphezulu/ubushushu obuphezulu.

Zonke ezi mveliso zintathu zenziwe kusetyenziswainkqubo yokubopha isinyithi engenamthungo, ukususa imithungo ye-weld emide eyiyona ndawo ibuthathaka kakhulu kwimibhobho egqunywe nge-welded.

Inzuzo Inkcazo
Ibhondi yokwenyani yesinyithi Amandla okucheba kojongano ≥300 MPa, adlula kakhulu iimfuno ze-API 5LD. Akukho kushwabana kwe-liner, ukudilika, okanye ukuqhekeka phantsi komjikelo wobushushu.
Ulwakhiwo olungenamthungo Zombini intsimbi engasemva kunye ne-CRA cladding azinamthungo – akukho mthungo we-weld weld ojikelezayo, zilungele inkonzo ye-hydrogen enoxinzelelo oluphezulu kunye negesi emuncu.
Ukudityaniswa kwezinto ezilungiselelwe wena Ukhetho olubanzi lweentsimbi ezixhasayo (intsimbi yekhabhoni ukuya kwi-T91) kunye nee-claddings ze-CRA (304L ukuya kwi-nickel alloys) ezihambelana neemfuno zokugqwala, ubushushu kunye noxinzelelo.
Uqoqosho oluphezulu I-alloy ebiza kakhulu isetyenziswa kuphela kwicala lokugqwala; ixabiso lezinto ezisetyenzisiweyo liphantsi ngama-30-60% kunepayipi eqinileyo ye-CRA enomlinganiselo ofanayo woxinzelelo.
Ukulandeleka okupheleleyo kunye namaxwebhu Isatifikethi se-EN 10204 Uhlobo lwe-3.1/3.2, iingxelo zovavanyo olupheleleyo lweekhemikhali, olwe-mechanical, lwe-NDT kunye nolwe-hydrostatic.
Ukusebenza okuqinisekisiweyo kwentsimi Inikezelwa kwizikhululo zamandla ezininzi, kwiindawo zokucoca, nakwiiprojekthi zaselwandle kwihlabathi liphela. Ukugqitywa kokugqiba kwenzelwe ukuwelda ngaphandle kweengxaki.

9. Imibuzo Ebuzwa Rhoqo (Imibuzo Ebuzwa Rhoqo)

Q1: Yintoni umahluko obalulekileyo phakathi kombhobho onamatheliswe ngesinyithi kunye nombhobho onamatheliswe ngoomatshini?
A: Kwipayipi ebotshelelwe ngesinyithi, i-interface yenza i-atomic-scale diffusion bond (amandla okucheba ≥300 MPa). Oku kuphelisa ngokupheleleyo ukushwabana kwe-liner, ukudilika okanye ukwahlukana, eziziingozi eziqhelekileyo kwipayipi ebotshelelwe ngoomatshini phantsi komjikelo wobushushu okanye i-pressure pulsation.

Umbuzo 2: Kutheni kusetyenziswe i-T91 (X10CrMoVNb9-1) endaweni ye-P91 njengomaleko wangaphandle?
A: I-T91 kunye ne-P91 zabelana ngendlela efanayo yekhemikhali. I-T91 yindlela yokuchonga ityhubhu engenamthungo (esetyenziselwa iityhubhu zebhoyila ezinobubanzi obuncinci, umz., ii-superheater bends), ngelixa i-P91 isetyenziselwa iipayipi ezinobubanzi obukhulu. I-T91 yeyona ndlela ifanelekileyo yokwenza ii-U-bends ze-superheater kunye ne-reheater.

Umbuzo 3: Yintoni umahluko phakathi kwe-UNS N08028 (i-Alloy 28) kunye ne-UNS N08825 (i-Incoloy 825)?
A: I-Alloy 28 ine-Cr, i-Mo kunye ne-Cu ephezulu, inika ukumelana okuphezulu kwi-sulfuric acid, i-phosphoric acid kunye neendawo ezine-chloride ephezulu (PREN 38-40). I-Incoloy 825 ine-nickel engaphezulu, okwenza ukuba imelane ngakumbi nokunciphisa ii-asidi kunye ne-hydrofluoric acid. Ikwabiza kakhulu ngokubanzi. Ukuze ufumane uhlalutyo oluthile oluphakathi, qhagamshelana neqela lobunjineli leWomic Steel.

Umbuzo 4: Ngaba umbhobho ogqunyiweyo we-P265GH + TP304L ungasetyenziselwa icandelo lobushushu obuphantsi kwibhoyila?
A: Ewe. I-P265GH inika amandla aphakathi obushushu kunye nokudityaniswa, ngelixa i-304L ingaphakathi imelana nokugqwala okuvela kwi-flue gas condensate (equlethe i-sulfurous acid). Kucetyiswa ukuba uvale iziphelo zetyhubhu emva kovavanyo lwe-hydrostatic ukuthintela ukugqwala ngaphambi kokuba kulungiswe.

Umbuzo 5: Ngaba ungabonelela ngesatifikethi se-EN 10204 Type 3.2 kunye nobungqina bomntu wesithathu?
A: Ewe. I-Womic Steel inentsebenziswano ende ne-SGS, i-BV, i-TÜV, i-DNV, i-ABS kunye ne-LR. Singalungiselela ubungqina bovavanyo lomntu wesithathu (umz., ukuxinana, i-UT) kwaye sikhuphe izatifikethi zohlobo lwe-3.2.

Umbuzo 6: Lingakanani ixesha eliqhelekileyo lokuhambisa la maqhagamshelo emibhobho egqunyiweyo?
A: Kwiiodolo zokuqala zeendibaniselwano ezisemgangathweni, ukuhanjiswa kudla ngokuba ziintsuku ezingama-60-90 (kubandakanya ukuthengwa kwezinto, ukukhupha izinto ezidityanisiweyo, ukugqitywa okubandayo kunye novavanyo). Kwiindibaniselwano esele zenziwe ngobuninzi (umz., P265GH+TP304L), ixesha lokunikezelwa linokwehliswa libe ziintsuku ezingama-45-60.
