What is a boiler tube?

Amashubhu e-boileramapayipi asetshenziselwa ukuthutha imidiya ngaphakathi kubhayela, axhuma izingxenye ezihlukahlukene zebhoyili ukuze kudluliselwe ukushisa okuphumelelayo.Lawa mashubhu angabaamashubhu ensimbi angenamthungo noma ashiselwefuthi zenziwacarbon steel, ingxubevange steel, noma insimbi engagqwalikuye ngezinga lokushisa, ingcindezi, kanye nezakhiwo zamakhemikhali zendlela ehanjiswayo.

Izinhlobo ze-Boiler Tube

I-tube yodonga epholile ngamanzi: Itholakala ku-boiler room, imunca ngokuqondile ukushisa kwelangabi kanye ne-high-temperature flue gas esithandweni bese ishisa amanzi abe isitimu.

Ishubhu ye-Superheater: Isetshenziselwa ukushisisa isitimu esigcwele esikhiqizwa ubhayela sibe isitimu esishisa kakhulu futhi kwandiswe izinga lokushisa lesitimu ukuze kuhlangatshezwane nezidingo zokukhiqizwa kwezimboni noma ukukhiqizwa kwamandla.

I-Reheater tube: Enjinini yesitimu, isetshenziselwa ukushisisa kabusha isitimu esenze umsebenzi ukuze kwandiswe izinga lokushisa kanye nokusebenza kahle kwesitimu.

Ishubhu yokonga amalahle: Itholakala ku-flue ekupheleni kwe-boiler, isetshenziselwa ukushisa kuqala amanzi angena ku-boiler ukuze kuncishiswe ukusetshenziswa kukaphethiloli we-boiler.

Ithubhu yokuqoqa: Isetshenziselwa ukuxhuma amashubhu kubhayela ukuze kuqoqwe noma kusatshalaliswe amanzi noma isitimu kubhayela.

I-Boiler Tube Materials

Lezi zihlanganisa amashubhu ensimbi ye-carbon, amashubhu ensimbi ye-alloy, namashubhu ensimbi engagqwali.Ukukhethwa kwezinto ezibonakalayo kuncike ezimweni zokusebenza ze-boiler, kufaka phakathi izinga lokushisa, ingcindezi kanye nezakhiwo zamakhemikhali ze-medium.

Ipayipi lensimbi ye-carbon: Ipayipi lensimbi ye-Carbon liwumthombo weshubhu kabhayela ovame ukusetshenziswa kwemidiya engathathi hlangothi noma ene-asidi ebuthakathaka, kanye nendawo enezinga lokushisa eliphakathi nendawo ukuya kweliphansi.Ipayipi lensimbi ye-Carbon linezakhiwo ezinhle zemishini nokusebenza kwe-welding, izindleko ziphansi.

Ipayipi yensimbi ye-alloy: Ipayipi lensimbi ye-alloy lisekelwe ku-carbon steel nezinye izakhi ze-alloying, njenge-chromium, i-nickel, i-molybdenum, njll., ukuthuthukisa ukumelana nokushisa, ukumelana nokugqwala, kanye nezakhiwo ze-mechanical zensimbi.Ipayipi lensimbi ye-alloy lifanele izinga lokushisa eliphezulu, ukucindezela okuphezulu, kanye nezindawo ezigqwalile.

Ipayipi lensimbi engagqwali: Ipayipi lensimbi engagqwali liqukethe izakhi ze-chromium ephezulu, linokumelana nokugqwala okuhle kakhulu, futhi lilungele i-asidi eqinile, i-alkali, nezimo ezishisa kakhulu.Amashubhu ensimbi engagqwali abiza kakhulu, kodwa ukuqina kwawo nokuthembeka kwawo kuwenza abe yizinto ezikhethwayo ezinhlelweni eziningi zezimboni.

Izindlela Zokukhiqiza

Izindlela zokukhiqiza amashubhu obhayela zihlukaniswa ikakhulukaziengenamthungo futhi eshiselwe.

Isinqumo sokusebenzisaengenamthungonoma amashubhu ensimbi ashiselwe kudingeka enziwe ngokusekelwe ezimeni zokusebenza kukabhayela, isilinganiso sokucindezela, izinga lokushisa, nezindleko.

Kuma-boilers anengcindezi ephezulu kanye namazinga okushisa aphezulu, amashubhu ensimbi angenamthungo avame ukukhethwa ukuze kuqinisekiswe ukuphepha nokuthembeka, kuyilapho ama-boilers aphansi naphakathi, amashubhu ensimbi ashiselwe angase abe ukukhetha ukonga.

Eminye Imibandela Eyenye

Ngaphezu kwezindinganiso ezishiwo ngokucacile ngenhla ukuze zisetshenziswe kuma-boilers, inani lezinye izindinganiso ngezinye izikhathi lisetshenziselwa ukwenziwa kwamashubhu obhayela.

Isibonelo, i-ASTM A53, i-ASTM A106, i-ASTM A335, i-ASTM A312, i-DIN 17175, i-EN 10216-2 ne-JIS G 3458.

Buyini Ubukhulu Bamashubhu Boiler?

Ngamazinga e-boiler tube ahlukene, ububanzi bosayizi bungase buhluke.

Amashubhu amaningi okubhayela anobubanzi obuncane obungaphandle, kuyilapho ubukhulu bodonga bukhethwa ngokusekelwe kungcindezi yokusebenza kanye nezakhiwo zemishini zezinto.

Isibonelo, indinganiso ye-ASTM A192 ingeyeshubhu yensimbi ye-carbon engenamthungo enobubanzi obungaphandle obungu-1/2 in. ukuya ku-7 in. (12.7 mm ukuya ku-177.8 mm) nogqinsi oluyi-0.085 in. ukuya ku-1 in. (2.2 mm ukuya 25.4 mm).

Uyini Umehluko Phakathi Kwamashubhu Boiler namashubhu ensimbi?

Amashubhu okushisa awuhlobo lwepayipi, kodwa aklanyelwe ukusetshenziswa okukhethekile kwama-boilers futhi anomklamo oqinile kanye nezidingo zempahla.Ishubhu, ngakolunye uhlangothi, igama elivame kakhulu elihlanganisa zonke izinhlelo zamapayipi ezisetshenziselwa ukuthutha uketshezi, okuhlanganisa kodwa okungagcini nje kumashubhu obhayela.

Mayelana NATHI

Kusukela yasungulwa ngo-2014, i-Botop Steel isiphenduke umhlinzeki oholayo wepayipi lensimbi eNyakatho neChina, elaziwa ngomsebenzi omuhle kakhulu, imikhiqizo yekhwalithi ephezulu, nezisombululo ezibanzi.

Le nkampani inikeza izinhlobonhlobo zamapayipi ensimbi ye-carbon nemikhiqizo ehlobene, okuhlanganisa ipayipi lensimbi engenamthungo, i-ERW, i-LSAW, ne-SSAW, kanye nohlu oluphelele lokufakwa kwamapayipi nama-flange.Imikhiqizo yayo ekhethekile ihlanganisa ama-alloys asezingeni eliphezulu kanye nezinsimbi ezingenasici ze-austenitic, ezenzelwe ukuhlangabezana nezidingo zamaphrojekthi ahlukahlukene wamapayipi.

Amathegi: I-Boiler Tube, usayizi weshubhu le-boiler, indinganiso yeshubhu le-boiler, engenamthungo, ipayipi lensimbi elishiselwe, ipayipi lensimbi ye-carbon.
