I-ASTM A179 / ASME SA179 Heat Exchanger Tubes - I-BLOG

Isingeniso

I-ASTM A179 / ASME SA179 ichaza amashubhu ensimbi angenamthungo, abandayo-adonswayo,{3}ekhabhoni ephansi aklanyelwe ukudluliswa kokushisa okuphumelelayo nokusebenza okuthembekile kokwakhiwa. Ngobuncane-ukwakhiwa kodonga kanye nokulawula okuqinile kwensimbi, lawa mashubhu asetshenziswa kakhulu kuma-heaters nama-condenser kuzo zonke izimboni zokucwenga, ze-petrochemical, nezimboni zamandla.I-Octal Pipe ihlinzeka ngamashubhu e-A179/SA179 e-EPC yomhlaba wonke nabakhi bemishini, esekela womabili amashubhu angenalutho kanye{0}}nama-U{0}}ama-bend assemblies.

Ukwakheka Kwamakhemikhali

Ikhabhoni ephansi{{0}ikhemikhali yekhabhoni ithuthukisa ukusebenza okubandayo kokuthi U-igobe kanye neshubhu-kuya-ukunwetshwa kwe-tubesheet.

Isici	Imfuneko (wt%)	Ubunjiniyela Ukubaluleka
Ikhabhoni (C)	0.06–0.18	Igcina i-ductility yokwakha
I-Manganese (Mn)	0.27–0.63	Ukuqinisa kanye ne-deoxidation
I-Phosphorus (P)	Ngaphansi noma kulingana no-0.035	Ikhawulela ukuqina
Isibabule (S)	Ngaphansi noma kulingana no-0.035	Hlanza indawo yangaphakathi kanye nokushisela

Izakhiwo Zemishini

Impahla	Imfuneko Encane	Iqhaza Ekushintshiseni Ukushisa
Amandla Okuqina	Kukhulu noma kulingana no-325 MPa (47 ksi)	Imajini yokuphepha yesakhiwo
Isivuno Amandla	Kukhulu noma kulingana no-180 MPa (26 ksi)	Ilawula ukuwohloka ngesikhathi sokwakheka
Ukwelula	Kukhulu noma kulingana no-35%	Ibalulekile ekwandiseni okuphephile
Ukuqina	Ngaphansi noma kulingana nama-72 HRB	Ivimbela ukuqhekeka phakathi-nokugoba

Lezi zakhiwo zinika amandla ukwenziwa okuphephile kanye nesevisi ezinzile kuzinqwaba zokushintshisana.

Ukukhiqiza Nokwelashwa Kokushisa

Amashubhu e-ASTM A179 / ASME SA179 akhiqizwa ngokugeleza komsebenzi okulawulwayo okungenamthungo okulandelwa ukudweba okunembayo okunembayo ukuze kutholwe ukubekezelela okuqinile kobukhulu kanye nezindawo ezibushelelezi zangaphakathi ukuze kuthuthukiswe ukushisa{2}}okudluliswa kahle.

Inqubo yokukhiqiza engenamthungo

I-billet engenalutho → ukubhoboza → ukubumba okushisayo → umdwebo -obandayo obandayo

Ukulawulwa kobukhulu kuqinisekisa ukuthi ubuncane{{0}imfuneko yodonga bufinyelelwa ngokunembile

Umdwebo obandayo uthuthukisa ukuphela kwendawo kanye nokuhlanzeka kwangaphakathi{0}okubalulekile ekwehliseni ukungcoliswa kwezishintshi zokushisa

Ukwelashwa kokushisa kokugcina

Ngemva komkhawulo wokugcina obandayo-amashubhu aphathwa ngokushisaInkulu noma ilingana no-1200℃F (Inkulu noma ilingana no-650 degree)kuya:

Yehlisa izingcindezi ezisalelayo ezibangelwa umsebenzi obandayo
Buyisela i-ductility edingekayo ukuzeU-ukugoba nokunwetshwa kwe-tubesheet
Thuthukisa{0}}ukuzinza kwesakhiwo sesikhathi eside ngaphansi kwemithwalo eshisayo ejikelezayo

Isimo sobuso nokulungiselela

Iziphetho kukhonaclean and burr{0}mahhala, ukuqinisekisa ukushisela okuthembekile noma ukunwetshwa komshini ngesikhathi somhlangano
Lokhu kulawulwa kokukhiqiza nokwensimbi kusiza ukuqinisekisa impilo ende yesevisi, ukwethembeka kwesakhiwo, nokufakwa okuphephile{0}kunqwaba yokushintshisana kwabantu abaningi.

Ukuhlola & Ukuhlola

Ngokuvumelana ne-ASTM A179 kanye ne-ASTM A450/A450M:
