Isu tanga takazvipira kupa chiyero chemakwikwi, chakanakisa zvigadzirwa zvemhando yepamusoro, zvakare sekukurumidza kuendesa kune Yepamusoro Pressure Boiler Pipe, Gamuchirai vatengi vese vekugara nekune dzimwe nyika kuti vaende kusangano redu, kugadzira inonakidza kwenguva refu nekubatana kwedu. Tichisimbirira pane yemhando yepamusoro mutsara manejimendi manejimendi uye vatengi rubatsiro rwehunyanzvi, isu zvino takagadzira gadziriso yedu kuti tipe vatengi vedu vachishandisa iyo kutanga nehuwandu hwekuwana uye mushure mesevhisi ruzivo runoshanda. Kuchengetedza hukama huripo hwehushamwari nevatengi vedu, isu zvakadaro tinogadzira mhinduro yedu inonyora nguva dzese kugutsa izvo zvinodikanwa zvitsva uye kuomerera kune yazvino-kusvika-zuva budiriro yemusika muMalta. Isu tanga takagadzirira kutarisana nekunetseka uye kuita kuvandudza kuti tinzwisise zvese zvingangoitika mukutengeserana kwenyika.
Application
Inonyanya kushandiswa kugadzira yakakwirira-mhando kabhoni structural simbi, alloy structural simbi uye isina kupisa-inodzivirira simbi isina musono pombi dzesimbi yekumanikidza yakakwira uye pamusoro pemhepo boiler pombi.
Inonyanya kushandiswa kune yakanyanya kudzvanywa uye yakanyanya tembiricha sevhisi ye boiler (Superheater chubhu, reheater chubhu, mhepo inotungamira chubhu, main steam chubhu yekumusoro uye yakanyanya kudzvanywa boilers). Pasi pechiito chepamusoro tembiricha flue gasi uye mhute yemvura, iyo chubhu ichave oxidize uye corrode. Zvinotarisirwa kuti pombi yesimbi ine kusimba kwepamusoro, kupikisa kwakanyanya kune oxidation uye corrosion, uye kunaka kwemaitiro kugadzikana.
Main Grade
Giredhi remhando yepamusoro kabhoni structural simbi: 20g, 20mng, 25mng
Giredhi yealloy structural simbi: 15mog, 20mog, 12crmog, 15crmog, 12cr2mog, 12crmovg, 12cr3movsitib, etc.
Giredhi resimbi inodzivirira kupisa-inodzivirira kupisa: 1cr18ni9 1cr18ni11nb
Kushivirira
Kukora Kwemadziro uye Kwekunze Diameter:
Kana pasina zvakakosha zvinodiwa, pombi ichaendeswa seyakajairika dhayamita yekunze uye yakajairika madziro ukobvu. As follow sheet

Urefu:
Iyo yakajairika urefu hwemapombi esimbi ndeye 4 000 mm ~ 12 000 mm. Mushure mekubvunzana pakati pemutengesi nemutengi, uye kuzadza chibvumirano, inogona kuendeswa simbi mapaipi nehurefu hunopfuura 12 000 mm kana kupfupika kupfuura I 000 mm asi kwete kupfupika kupfuura 3 000 mm; hurefu hupfupi Huwandu hwepombi dzesimbi dziri pasi pe 4,000 mm asi dzisingasviki 3,000 mm hadzifanire kudarika 5% yehuwandu hwemapombi esimbi akaunzwa.
Delivery uremu:
Kana pombi yesimbi ichiunzwa zvinoenderana nedhayamita rekunze rekunze uye ukobvu hwemadziro hwezita kana dhayamita yemukati yemukati uye dhayamita remadziro, pombi yesimbi inounzwa zvinoenderana nehuremu chaihwo. Inogonawo kuendeswa maererano nehuremu hwe theoretical.
Kana iyo pombi yesimbi inounzwa maererano nezita rekunze dhayamita uye hushoma rusvingo ukobvu, pombi yesimbi inounzwa maererano nehuremu chaihwo; mapato ekupa nekudiwa anotaurirana. Uye inoratidzwa muchibvumirano. Iyo pombi yesimbi inogonawo kuendeswa maererano nehuremu hwe theoretical.
Weight tolerance:
Zvinoenderana nezvinodiwa nemutengi, mushure mekubvunzana pakati pemutengesi nemutengi, uye muchibvumirano, kutsauka pakati pehuremu chaihwo uye huremu hwekufungidzira hwepombi yesimbi yekutakura huchasangana nezvinodiwa zvinotevera:
a) Single simbi pombi: ± 10%;
b) Batch rimwe nerimwe remapombi esimbi ane saizi shoma yegumi t: ± 7.5%.
Test Chinodiwa
Hydraustatic Test:
Iyo pombi yesimbi inofanirwa kuongororwa hydraulically imwe neimwe. Iyo yakanyanya test pressure ndeye 20 MPa. Pasi pekumanikidzwa kwekuedza, nguva yekudzikamisa inofanira kunge isiri pasi pe10 s, uye pombi yesimbi haifaniri kudonha.
Mushure mekunge mushandisi abvuma, iyo hydraulic bvunzo inogona kutsiviwa needdy yazvino kuyedza kana magineti flux kuvuza kuyedzwa.
Nondestructive Test:
Mapaipi anoda kuongororwa zvakanyanya anofanirwa kuongororwa ultrasonically imwe neimwe. Mushure mokunge nhaurirano inoda kubvumirwa kwebato uye inotsanangurwa muchibvumirano, kumwe kuedza kusina kuparadza kunogona kuwedzerwa.
Flattening Test:
Machubhu ane dhayamita rekunze rakakura kudarika 22 mm achaiswa muyedzo yekubata bata. Hapana delamination inooneka, mavara machena, kana tsvina inofanirwa kuitika panguva yese yekuyedza.
Flaring Test:
Zvinoenderana nezvinodiwa nemutengi uye zvakataurwa muchibvumirano, pombi yesimbi ine dhayamita yekunze ≤76mm uye ukobvu hwemadziro ≤8mm inogona kuitwa flaring test . Kuedza kwakaitwa pakamuri tembiricha ine taper ye60 °. Mushure mekupisa, mwero wekupisa wedhayamita yekunze unofanirwa kusangana nezvinodiwa zvetafura inotevera, uye zvinhu zvekuyedza hazvifanirwe kuratidza kutsemuka kana kubvaruka.
