DESCRIPTION
Insimbi engagqwali engu-317L iyibanga le-molybdenum eliqukethe ikhabhoni ephansi, kanye nezithako ze-chromium, i-nickel, ne-molybdenum. Lokhu kunikeza ukumelana nokugqwala okungcono kanye nokwanda kokumelana nokuhlaselwa kwamakhemikhali kusuka ku-acetic, tartaric, formic, citric, kanye ne-sulfuric acid. Amashubhu/amapayipi angu-317L ahlinzeka ngokukhasa okuphezulu, nokumelana nokuzwela lapho eshiselwe, ngenxa yokuqukethwe kwekhabhoni ephansi. Izinzuzo ezengeziwe zihlanganisa ingcindezi ekumelaneni nokuqhekeka, namandla okuqina emazingeni okushisa aphakeme. Amapayipi ensimbi eBanga le-317l awawona ama-magnetic esimweni esifakwe emanzini. Kodwa-ke, i-post-welding magnetism encane ingabonwa.
317L IZIMPAPHA ZAMAPHAYISI EZINSIZI
Amashubhu ensimbi engagqwali angu-317L ahlinzekwa yi-Arch City Steel & Alloy aqukethe lezi zakhiwo ezilandelayo:
Ukumelana Nokugqwala:
- Ibonisa ukumelana nokugqwala okukhethekile ezindaweni ezihlukahlukene, ikakhulukazi ezindaweni ezine-acidic chloride kanye nohlu olubanzi lwamakhemikhali.
- Ukumelana nokugqwala okuhle kakhulu ezinhlelweni lapho ukungcola okuncane kuyadingeka
- 317L ithubhu/ipayipi lensimbi engagqwali elinokuqukethwe kwekhabhoni ephansi linikeza ukumelana okuhle nokugqwala kwe-intergranular
- Ukuthambekela kwensimbi emigodini lapho ihlangana nama-chloride, ama-bromide, ama-phosphorus acid, nama-iodide kuyacindezelwa.
Ukumelana Nokushisa:
- Ukumelana okuhle kakhulu ne-oxidation ngenxa yokuqukethwe kwe-chromium-nickel-molybdenum.
- Ibonisa izinga eliphansi lokukala emazingeni okushisa afika ku-1600-1650°F (871-899°C), emkhathini ojwayelekile.
Izici zokushisela:
- Ngaphandle kwe-oxyacetylene welding, eshiselwe ngempumelelo yizo zonke izindlela ezivamile zokuhlanganisa nezindlela zokumelana.
- Insimbi yokugcwalisa ene-nickel-base kanye nokuqukethwe kwe-chromium ne-molybdenum eyanele kufanele kusetshenziselwe ukushisela uhlobo lwensimbi engu-317L. Lokhu kusiza ekuthuthukiseni ukumelana nokugqwala komkhiqizo oshiselwe. I-AWS E317L/ER317L noma i-austenitic, izinsimbi zokugcwalisa ikhabhoni ephansi ezinokuqukethwe okuphezulu kwe-molybdenum kune-grade 317L nazo zingasetshenziswa.
Ukusebenziseka:
- Ukusebenza ngesivinini esiphansi ngokuphakelayo okungaguquki kusiza ukunciphisa ukuthambekela kwamapayipi ebanga lama-317L ukuqina.
- Amapayipi ensimbi engagqwali eBanga 317L aqinile kunama-304 angenasici futhi angaphansi kwe-chip ende nelinezintambo lapho esebenza ngomshini. Ngakho-ke, kunconywa ukusebenzisa ama-chip breakers.
Izicelo:
Amashubhu ensimbi engagqwali eBanga lama-317L ajwayele ukusetshenziselwa ukuphatha utshwala, odayi be-asidi, izixazululo zokuxubha, ingxube ye-acetylating ne-nitrate, njll. Okunye ukusetshenziswa okukhethekile kwamashubhu namapayipi ebangeni elingu-317L kuhlanganisa:
- Imishini yokucubungula amakhemikhali kanye ne-petrochemical
- Imishini yokuphatha iphepha ne-pulp
- Imishini yokucubungula ukudla
- Ama-Condensers eziteshini ezisebenza nge-nuclear ne-fossil
- Imishini yendwangu
