Chii chinonzi STPG 370 Pipe Material?

STPG 370 igiredhi yakaderera-kabhoni simbi pombi giredhi inotsanangurwa muyero yeJapan JIS G 3454.

STPG 370 ine simba shoma rekuita 370 MPa uye simba regoho shoma re215 MPa.

STPG 370 inogona kugadzirwa semachubhu esimbi asina musono kana welded simbi machubhu uchishandisa electric resistance welding (RW) process.Yakakodzera kushandiswa mukumanikidza pombi masisitimu ane tembiricha yekushandisa inosvika 350 ° C.

Tevere, isu tichatarisa STPG 370 kubva mukugadzira maitiro, kuumbwa kwemakemikari, michina zvivakwa, hydrostatic pressure bvunzo, isinga paradza kuyedza, uye galvanized coating.

Manufacturing Process

JIS G 3454 STPG 370 inogona kugadzirwa uchishandisa iyoisina musono or ERWnzira yekugadzira, yakasanganiswa nenzira dzakakodzera dzekupedzisa.

Pamusoro pesimba rekusimba, kusimba kwesimba, uye kurebesa kwataurwa pamusoro, kune zvakare bvunzo yekudzikamisa uye bendability.

Flattening Test: Kana kureba pakati pemahwendefa maviri kunosvika kureba H, hapazovi nekuremara kana kuputika pamusoro pepombi yesimbi.

Bendability: Iyo pombi inofanira kupetwa 90 ° paradius ye6 nguva yekunze kwayo.Rusvingo rwepombi harufanire kunge rwusina kukanganisa kana kutsemuka.

Kuedzwa kweHydrostatic kana Kusina-kuparadza Muedzo

Imwe neimwe pombi yesimbi inoiswa kune hydrostatic bvunzo kana isiri-inoparadza bvunzo kuti itarise chero hurema husingaonekwe neziso rakashama.

Hydrostatic Test

Zvinoenderana neyakarongwa giredhi yehukobvu hwemadziro epombi yesimbi, sarudza iyo yakakodzera yekumanikidza mvura kukosha, ichengetedze kweinenge 5 masekonzi, uye tarisa kana pombi yesimbi iri kubuda.

Muedzo usingaparadzi

Kana ultrasonic inspection yakashandiswa, inofanirwa kunge yakavakirwa pachiyero chakasimba kupfuura UD kirasi chiratidzo muJIS G 0582.

Kana eddy yazvino kuyedza ikashandiswa, inofanirwa kuve yakavakirwa pachiyero chakanyanya kuomarara kupfuura EY kirasi chiratidzo muJIS G 0583.

Galvanized

MuJIS G 3454, mapaipi esimbi asina kuvharwa anonzimapaipi matemauye mapaipi esimbi anonzi galvanizedmapaipi machena.

White pombi: galvanized simbi pombi

Black pipe: isiri-galvanized simbi pombi

Maitirwo epombi machena ndeekuti mapombi matema anokwenenzverwa anopfurwa-kuputika kana kunyungudutswa kuti abvise tsvina pamusoro pepombi yesimbi yobva yaiswa zinc inosangana neJIS H 2107 chiyero chegiredhi 1. Dzimwe nyaya dzinoitwa zvinoenderana neJIS H 8641 standard.

Hunhu hweiyo zinc coating inotariswa zvinoenderana nezvinodiwa zveJIS H 0401, Chinyorwa 6.

Nezvedu

Kubva pakavambwa muna 2014.Botop Steelrave mutengesi anotungamira wekabhoni simbi pombi kuChamhembe kweChina, inozivikanwa nebasa rakanakisa, zvigadzirwa zvemhando yepamusoro, uye mhinduro dzakakwana.

Iyo kambani inopa dzakasiyana siyana dzekabhoni simbi mapaipi uye zvigadzirwa zvine hukama, zvinosanganisira isina musono, ERW, LSAW, uye SSAW simbi pombi, pamwe neyakakwana mutsara wepombi fittings uye flanges.Zvigadzirwa zvayo zvehunyanzvi zvinosanganisira alloys epamusoro-giredhi uye austenitic simbi isina tsvina, yakagadzirirwa kusangana nezvinodiwa zveakasiyana mapurojekiti epombi.
