Duplex UNS S31803
Duplex UNS S31803 Amakuru ya tekiniki
Incamake
Duplex ni austenitis ferritic Iron Chromium-Nickel alloy hamwe na Molybdenim wongeyeho. Ifite imbaraga zo kurwanya umwobo, imbaraga nyinshi kandi irwanya imbaraga zo kwangirika kwangirika ku bushyuhe buringaniye n’icyuma gisanzwe cya austenitis.
Duplex ni ibikoresho bifite igereranyo kingana na austenite na ferrite. Ibi bihuza imbaraga zo kurwanya ruswa n'imbaraga nyinshi. Ibikoresho bya mashini byikubye kabiri ibyuma bya austenitike idasanzwe hamwe no kurwanya ihungabana rya ruswa iruta ubwoko 316 ibyuma bitagira umwanda mubisubizo bya chloride. Ibikoresho bya Duplex bifite inzibacyuho / yoroheje kuri -50 ° C. Ubushyuhe bwo hejuru bukunze kugarukira ku bushyuhe ntarengwa bwa 300 ° C kugirango bukoreshwe igihe kitazwi kubera kwinjiza.
Inyungu
Hariho inyungu nyinshi za Duplex harimo:
Imbaraga Zirenze
Kurwanya cyane gutobora, crevice kurwanya ruswa
Kurwanya cyane guhangayika guturika, umunaniro nisuri
Kurwanya bihebuje kurwanya Chloride guhangayika
Kwiyongera k'ubushyuhe buke hamwe n'ubushyuhe bukabije kuruta ibyuma bya Austenitike
Kwinjiza ingufu nyinshi
Gukora neza no gusudira
Porogaramu
Umuyoboro - ASTM A790
Uburyo bwo gukora bushobora kuba bumwe cyangwa gusudira mu buryo bwikora, nta kongeramo ibyuma byuzuza. Umuyoboro urashobora kuba ushushe cyangwa ubukonje burangiye ariko ugomba guhora utangwa muburyo bwo kuvura ubushyuhe.
ARIKO WELD - ASTM A815
Iki cyiciro gikubiyemo icyiciro cya WP, kigizwe nibyiciro 4 kandi byujuje ibisabwa na ANSI B16.9. Ibipimo byumuvuduko nuburyo bumwe bwo guhuza imiyoboro.
Ibyiciro: -
WP-S: Ubwubatsi butagira akagero
WP-W: Ubwubatsi bwubatswe aho gusudira ubwubatsi bifotorwa
WP-WX: Kubaka gusudira aho gusudira byose bifotorwa
WP-WU: Ubwubatsi bwubatswe aho al welds igeragezwa Ultrasonically.
Flanges ASTM A182
Ibisobanuro bya ASTM bigena ibikoresho fatizo byemewe biva muri flanges. Ibyuma byahimbwe cyangwa bizunguruka ibyuma bya flanges, ibyuma byahimbwe hamwe na valve kubushyuhe bwo hejuru.
Agaciro ASTM A890 Icyiciro cya 5A
Ibisobanuro bisanzwe kubakinnyi, lron-Chromium-Nickel-Molybdenum Ruswa-
Kurwanya, Duplex (Austenitike / Ferritic) kubisabwa muri rusange '
