Kureba:
Kureba kwemapaipi esimbi kwakajairika i4 000 mm ~ 12 000 mm. Mushure mekubvunzana pakati pemutengesi nemutengi, uye kuzadza chibvumirano, mapaipi esimbi anogona kuunzwa ane hurefu hunopfuura 12 000 mm kana hupfupi pane 1 000 mm asi husiri hupfupi pane 3 000 mm; hupfupi Huwandu hwemapaipi esimbi ari pasi pe4,000 mm asi husingasviki 3,000 mm hahufanirwe kudarika 5% yehuwandu hwese hwemapaipi esimbi anopiwa.
Kurema kwekutumira:
Kana pombi yesimbi ikaendeswa zvichienderana nedhayamita yekunze yakataurwa uye ukobvu hwemadziro kana dhayamita yemukati yakataurwa uye ukobvu hwemadziro, pombi yesimbi inoendeswa zvichienderana nehuremu chaihwo. Inogonawo kuendeswa zvichienderana nehuremu hwepfungwa.
Kana pombi yesimbi yaendeswa zvichienderana nedhayamita yekunze uye ukobvu hwemadziro hushoma, pombi yesimbi inoendeswa zvichienderana nehuremu chaihwo; mapato ekupa nekukumbira anotaurirana. Uye zvinoratidzwa muchibvumirano. Pombi yesimbi inogonawo kuendeswa zvichienderana nehuremu hwedzidziso.
Kurema kushivirira:
Zvichienderana nezvinodiwa nemutengi, mushure mekubvunzana pakati pemutengesi nemutengi, uye muchibvumirano, kutsauka pakati pehuremu chaihwo nehuremu hwepfungwa hwepombi yesimbi yekutumira kunofanira kuzadzisa zvinodiwa zvinotevera:
a) Pombi yesimbi imwe chete: ± 10%;
b) Boka rega rega remapaipi esimbi ane saizi shoma ye10 t: ± 7.5%.
Kuedzwa kweHydraustatic:
Pombi yesimbi inofanira kuyedzwa hydraulic imwe neimwe. Kumanikidzwa kwakanyanya kwekuyedzwa i20 MPa. Pasi pekumanikidzwa kwekuyedzwa, nguva yekudzikamisa haifanirwe kunge iri pasi pe10 s, uye pombi yesimbi haifanirwe kudonhedza mvura.
Mushure mekunge mushandisi abvuma, bvunzo ye hydraulic inogona kutsiviwa ne eddy current testing kana magnetic flux leakage testing.
Muedzo Usingaparadzi:
Mapaipi anoda kuongororwa zvakanyanya anofanira kuongororwa ne ultrasound imwe neimwe. Mushure mekunge hurukuro yada mvumo yebato uye yatsanangurwa muchibvumirano, kumwe kuyedzwa kusingakuvadzi kunogona kuwedzerwa.
Muedzo weKupwanya:
Machubhu ane dhayamita yekunze inodarika 22 mm anofanira kuongororwa kuti apfava. Hapana kupatsanurwa kunooneka, mavara machena, kana tsvina zvinofanirwa kuitika panguva yese yekuedza.
Kuedza Kupisa:
Zvichienderana nezvinodiwa nemutengi uye zvakataurwa muchibvumirano, pombi yesimbi ine dhayamita yekunze ≤76mm uye ukobvu hwemadziro ≤8mm inogona kuitwa bvunzo yekupfura. Kuedza kwakaitwa patembiricha yemukamuri netaper ye60 °. Mushure mekupfura, mwero wekupfura kwedhayamita yekunze unofanirwa kusangana nezvinodiwa patafura inotevera, uye zvinhu zvekuyedza hazvifanirwe kuratidza mitswe kana kubvaruka.
