Ibisobanuro:Ingano za ASTM A312 TP321 zakuwemo amazi n'ibinyampeke, zikozwe mu mazi. Isuzuma rya Hydrostatic. 100% UT ku miyoboro ya EFW, umuyoboro wa eddy kuri ERW. PMI kuri buri muyoboro. Isuzuma rya corruption risabwa hagati y'udusimba kuri ASTM A262 Imyitozo E (nta gitero cyagabweho). Kuri TP321H (igice cya 6″ cy'imirasire): isuzuma rya creep rirushijeho kwiyongera kuri 650°C (ingufu za spec rupture > 50 MPa ku masaha 100.000). Isuzuma rya radiyo (100%) ku miyoboro ya EFW. Isuzuma rya gatatu ryakozwe na TÜV USA.
Porogaramu:Gusimbuza ibice by'amashanyarazi bishyushya umuriro n'ibice by'imirasire mu ruganda rutunganya amavuta ya kera (icyuma cyatinze). Imiyoboro ya 3″ na 4″ yari iy'igice cy'imirasire (ubushyuhe 450-600°C). Imiyoboro ya TP321H ya 6″ yari iy'igice cy'imirasire cyashyizwe ku muriro (650-800°C). Imiyoboro ya 8″ yari iy'ibice byo gusohoka. Amazi yo mu nganda: umwuka wa hydrocarbon ufite H₂S na chloride. Umuvuduko w'imikorere ni 2.5 MPa.
Imiterere y'Ubwubatsi:Imiyoboro ya heater yabanje (304H) yananiwe nyuma y'imyaka 8 bitewe no gushyushya no kugabanuka k'urumuri rwa sigma bitewe no gushyuha kenshi (gutangira/guhagarara kw'imashini). TP321 yatoranijwe kubera guhagarara kwayo kwa titanium, bibuza imvura ya chromium carbide ndetse na nyuma yo gushyushya/gukonjesha kenshi binyuze mu cyiciro cyo gushyushya. TP321H mu gice cy'imirasire itanga imbaraga nyinshi zo gushyushya kuri 650-750°C.
Ibibazo bya tekiniki n'ibisubizo:
Kurinda ubukana bw'ibikoresho mu gihe cyo gusudira no gutanga serivisi– TP321 isaba gukurura neza umuti nyuma yo gusudira kugira ngo ishongeshe karubide za titanium. Womic yakoze gukurura umuti ku bushyuhe bwa 1080°C ± 10°C, amazi arazimwa. Ikizamini cya corrosion intergranular (A262 Practice E) ku ngero zo gusudira nta gitero cyagaragaje (cyatsinze igipimo cya corrosion cya 0.0 mm/min). Inzobere mu by'icyuma yemeje ko gukonjesha titanium byagize akamaro.
Ingufu zo gukurura ubushyuhe bwinshi ku gice cy'imirasire (6″ TP321H)– Igice cy’imirasire gikorera ku bushyuhe bwa 750°C. TP321 isanzwe yari kugabanya igihe cyo gucika kw’imashini. Womic yatanze TP321H irimo karuboni 0.06-0.08% n’ingano y’ibinyampeke ASTM 5-6 (igenzurwa). Twakoze ikizamini cyo gucika kw’imashini ku bushyuhe bwinshi kuri 650°C: umusaruro wa 115 MPa, gucika kw’imashini 280 MPa (hejuru y’igihe gito gisabwa). Ikizamini cyo gucika kw’imashini (amasaha 1.000 kuri 650°C, 70 MPa) nta gucika kw’imashini kwagaragaje. Umukiriya yemeye ibikoresho.
Gutunganya ubushyuhe no kugenzura ubushyuhe– Gusudira TP321 mu nganda zitunganya ibinyabutabire bisaba umwuka uturutse inyuma (argon) kugira ngo hirindwe ogisijeni y’imbere mu mubiri (igipimo cy’isukari). Womic yatanze imiyoboro ifunze neza ifite imiyoboro isukuye kandi yatanzweho inama yo gusudira: inzira y’imizi ya GTAW ifite umugongo wa argon, hanyuma hagakurikiraho SMAW fill. Twatanze coupons 50 zo gusudira kugira ngo harebwe niba igikorwa kigomba gukorwa. Coupons zose zatsinze isuzuma rya radiyo n’irya PT.
Igenzura rya PMI kuri TP321 vs 304/316– Umukiriya yasabaga PMI 100% kubera ibyago byo kuvanga na 304/316 isanzwe. Womic yakoze XRF kuri buri muyoboro (impande zombi). Isonga rya Titanium ryemejwe mu miyoboro yose. Nta kintu na kimwe cyagaragaye.
Umuyoboro munini wa santimetero 8 woroshye mu gukora ibintu byinshi– Imashini ya 8″ yasohokeraga yasabaga kugororoka kwa mm 2 kuri metero 3 kugira ngo ihuzwe neza n'udupira. Womic yakoresheje imashini itunganya imigozi n'uburyo bwo guhuza imigozi hakoreshejwe laser. Kugororoka kwa nyuma kwageze kuri mm 1.0-1.5 kuri metero 3.
Ibikoresho bijya mu ruganda rukora isuku (ingengabihe y'ivugurura)– Gusimbuza icyuma gishyushya byari biteganijwe mu gihe cy’ibyumweru 6 (igihe ntarengwa). Womic yazanye imiyoboro yose mu buryo bumwe (toni 50) ibyumweru 2 mbere yuko itangira gukoreshwa. Imiyoboro yoherejwe iva i Shanghai ijya i Houston, hanyuma ijyanwa mu ruganda rutunganya. Gutanga ku gihe byatumye ishyirwaho ako kanya.
Ibisubizo:Igishyushya cyakoreshejwe cyongeye gutangira neza nyuma yo kugihindura. Nyuma y'amezi 18 gitangiye gukora (harimo n'ihindagurika ry'ubushyuhe), igenzura nta kimenyetso cyagaragaje cyo kubyibuha, kwangirika, cyangwa guhinduka kw'ingufu. Umukiriya yashyizeho uburyo bwa TP321 ku miyoboro yose ya heater ya coker unit kugira ngo ihindurwe mu gihe kizaza. Womic Steel ubu ni yo isabwa cyane mu kugurisha imiyoboro ya fertilizer ishyushye cyane muri uru ruganda.
