Khoom cim npe

STPG 370 yeeb nkab khoom yog dab tsi?

STPG 370 yog qib qis-carbon steel yeeb nkab tau teev nyob rau hauv Japanese tus qauv JIS G 3454.

STPG 370 muaj qhov tsawg kawg nkaus tensile zog ntawm 370 MPa thiab qhov tsawg kawg nkaus yield zog ntawm 215 MPa.

STPG 370 tuaj yeem ua tau raws li seamless steel hlab lossis welded steel hlab siv cov txheej txheem hluav taws xob tiv thaiv vuam (ERW).Nws yog tsim rau siv nyob rau hauv siab piping systems nrog kev khiav hauj lwm kub txog li 350 ° C.

Tom ntej no, peb yuav saib STPG 370 los ntawm kev tsim cov txheej txheem, tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, kev ntsuas hydrostatic siab, kuaj tsis muaj kev puas tsuaj, thiab txheej txheej galvanized.

Ntxiv nrog rau lub zog tensile, lub zog tensile, thiab elongation tau hais los saum toj no, kuj tseem muaj kev sib tw flattening thiab bendability.

Flattening Test: Thaum qhov kev ncua deb ntawm ob daim hlau mus txog qhov kev ncua deb H, yuav tsum tsis muaj qhov tsis xws luag lossis tawg ntawm cov yeeb nkab steel.

Kho tau: Cov yeeb nkab yuav tsum tau khoov 90 ° ntawm lub vojvoog ntawm 6 npaug ntawm nws txoj kab uas hla.Cov phab ntsa yeeb nkab yuav tsum tsis muaj qhov tsis xws luag lossis tawg.

Hydrostatic Test lossis Non-destructive Test

Txhua cov yeeb nkab steel yog raug rau qhov kev sim hydrostatic los yog tsis muaj kev puas tsuaj los kuaj xyuas qhov tsis xws luag uas tsis pom ntawm qhov muag liab qab.

Hydrostatic Test

Raws li lub sijhawm teem tseg ntawm cov phab ntsa tuab ntawm cov yeeb nkab steel, xaiv qhov tsim nyog tus nqi dej siab, tuav nws li 5 vib nas this, thiab xyuas seb cov yeeb nkab steel puas.

Kev kuaj tsis muaj kev puas tsuaj

Yog tias kev tshuaj xyuas ultrasonic siv, nws yuav tsum ua raws li tus qauv nruj dua li UD chav kawm teeb liab hauv JIS G 0582.

Yog tias kev ntsuas tam sim no raug siv, nws yuav tsum ua raws li tus qauv uas nruj dua li EY chav teeb liab hauv JIS G 0583.

Galvanized

Nyob rau hauv JIS G 3454, uncoated steel kav yog hu uacev dubthiab galvanized steel kav yog hu uacov kav dej dawb.

Cov yeeb nkab dawb: galvanized steel yeeb nkab

Dub yeeb nkab - tsis yog-galvanized steel yeeb nkab

Dub yeeb nkab: tsis-galvanized steel yeeb nkab

Cov txheej txheem rau cov kav dej dawb yog tias cov kav dej dub uas tsim nyog tau raug tua-blasted lossis pickled kom tshem tawm cov impurities ntawm qhov chaw ntawm cov yeeb nkab steel thiab tom qab ntawd galvanized nrog zinc uas ua tau raws li JIS H 2107 tus qauv ntawm yam tsawg kawg yog qib 1. Lwm yam teeb meem yog nqa tawm. raws li JIS H 8641 tus qauv.

Cov yam ntxwv ntawm zinc txheej raug kuaj xyuas raws li qhov yuav tsum tau ua ntawm JIS H 0401, Tshooj 6.
