1. Mitemo yekushandisa
Simbisa yazvino vhezheni yeASTM A333/A 333M (iyo kemikari yevhezheni yevhezheni mushure megore ra2016 yakagadziridzwa, uye zvitsva zvinorambidzwa senge Cr, Ni, uye Mo zvinowedzerwa).
2. Kemikari inogadzirisa kutonga
Key element zvinogumira:
C≤0.30% (yakaderera kabhoni inovimbisa kuoma), Mn 0.29-1.06% (yakagadziridzwa neC content), P≤0.025%, S≤0.025% (kunyatsodzikamisa zvinhu zvinokuvadza).
Shanduro ye2016 inowedzera miganhu yepamusoro yeNi, Cr, Mo, nezvimwewo (zvakadai seNi≤0.40%), uye zvakakosha kutarisa kana bhuku rewaranti rakanyorwa nekabhoni yakaenzana (CET).
Kukwidziridzwa kwezvinhu: Iyo itsva vhezheni yeA333GR6 yakakwidziridzwa kubva kuC-Mn simbi kuenda kune yakaderera alloy simbi, nekuita zvirinani.
1. Mechanical properties
Tensile simba ≥415MPa, goho simba ≥240MPa, yakaderera goho simba reshiyo (inoratidza epurasitiki deformation kugona)
Low tembiricha kukanganisa bvunzo:
Tembiricha yekuyedza inosiyana nekukora kwemadziro (senge -45 ℃~-52 ℃), uye zvinodiwa nekondirakiti zvinofanirwa kutaurwa zvakajeka.
Iko kukosha kwesimba kunofanirwa kusangana neyakajairwa, kazhinji inoda ≥20J (ona ASTM A333 kuti uwane ruzivo).
2. Metallographic chimiro
Mamiriro ekupa anofanira kunge ari yunifomu ferrite + pearlite, ine saizi yezviyo 7 ~ 9 (makora zviyo anogona kuderedza goho reshiyo yesimba).
Zviri nani sarudza mapaipi esimbi akadzimwa + akadzimwa (iyo chimiro chinodziya troostite, uye kusimba kwakadzika-tembiricha kuri nani).
Kupisa kurapwa maitiro
Marekodhi ekurapa kupisa anofanirwa kupihwa: kudziyisa ≥815℃→kudzima mvura→kudzikamisa kuti ive nechokwadi chekufanana kwechimiro.
Dzivisa kusarapwa kana kubatwa zvisina kunaka mamiriro ekutanga (yakaomarara chimiro chinotungamira kune yakaderera-tembiricha brittleness).
Delivery status
Kazhinji inounzwa mune yakajairwa + yakapfava kana kudzimwa + yakashatirwa, iyo inoda kutsanangurwa muchibvumirano.
1. Wall ukobvu uye kukanganisa tembiricha kuwirirana
Semuyenzaniso: kana kukora kwemadziro kuri 7.62mm, tembiricha yekukanganisa bvunzo inoda kusvika -52 ℃ (yakaderera pane chiyero -45 ℃).
Zvakajairwa nzvimbo yakatarwa: 8-1240mm×1-200mm (SCH5S-XXS), kudiwa chaiko kunoda kuongororwa.
2. Yakaenzana zvimwe zvinhu
A333GR6≈X42N/L290N/API 5L B PSL2 (pombi yemutsetse), asi zvinodiwa kuti usimbise kana tembiricha yakaderera yasangana.
Unofanira-kutarisa magwaro
Material certification (MTC), mushumo wekupisa kupisa, yakaderera tembiricha kukanganisa bvunzo mushumo, isiri-inoparadza yekuyedza mushumo (UT/RT).
Mushure meiyo 2016 vhezheni, iyo data yekuyedza yezvinhu zvichangobva kuwedzerwa alloy (Ni, Cr, nezvimwewo) inofanira kuverengerwa.
Wechitatu-bato kuongorora zvakare
Zvinokurudzirwa kuongorora zvakare zvinhu zvakakosha (sekukanganisa bvunzo, kuumbwa kwemakemikari) nesampling, kunyanya kune zvine njodzi maapplication (senge LNG mapaipi).
Tembiricha range
Yakagadzirwa tembiricha yekushandisa ≥-45 ℃, yakanyanya-yakaderera tembiricha mamiriro (se -195 ℃) anoda kuongorora kana giredhi repamusoro (seA333GR3/GR8) rinodiwa.
Indasitiri application
Petrochemical (ethylene, LNG), midziyo yefiriji, mapaipi e-cryogenic, nezvimwewo, inoda kufunga nezvekuwedzera kuchengetedza (sekupfeka) zvinoenderana nekuora kwepakati.
Qualifications uye maitiro
Sarudzo sarudza vagadziri vane ASTM A333 zvigadzirwa zvekugadzira, uye zvinoda makesi ekupa emapurojekiti akafanana.
Ngwarira maitiro evatengesi '"OEM" uye simbisa mapepa ewaranti yefekitori yekutanga.
Mutengo uye nguva yekuendesa
Iyo yakaderera-alloy vhezheni (pamberi 2016) inogona kuva nemutengo wakaderera, asi mutsauko wekuita wakakura, uye mutengo wakakwana wekuita unodiwa.
Special specifications (senge hombe-diameter gobvu-yakavezwa mapaipi) ingangoda kugadzirwa, ichiwedzera kutenderera kutenderera.
Ngozi yekuvhiringika: Usavhiringa A333GR6 neA335GR6 (chromium-molybdenum simbi yekupisa kwakanyanya).
Old standard inventory: Simbisa kana pombi yesimbi inogadzirwa mushure meiyo 2016 vhezheni kudzivirira alloy zvinhu zvechinyakare zvigadzirwa zvisiri kusangana nezviyero.
Welding process: Yakadzika-tembiricha simbi pombi welding inoda kuenzanisa welding zvinhu (senge ENiCrMo-3), uye mutengesi anofanirwa kupa kutungamira kwewelding.
Kuburikidza nemapoinzi ari pamusoro, mutengi anogona kunyatso ongorora kutevedza, kuita kuenzanirana uye kuvimbika kwemupi weA333GR6 alloy pombi kuti ave nechokwadi chekuchengetedza uye hupfumi hwepurojekiti.
