Chii chinonzi STPG 370 Pipe Material?

STPG 370 imhando yemapaipi esimbi ane kabhoni shoma anotsanangurwa muJIS G 3454 yechiJapan.

STPG 370 ine simba rekudhonza re370 MPa uye simba rekugovanisa re215 MPa.

STPG 370 inogona kugadzirwa semachubhu esimbi asina musono kana machubhu esimbi akasungirirwa uchishandisa nzira yemagetsi yekubatanidza welding (ERW). Yakakodzera kushandiswa mumapombi ane pressure ane tembiricha yekushanda inosvika 350°C.

Tevere, tichatarisa STPG 370 kubva mumaitiro ekugadzira, kuumbwa kwemakemikari, hunhu hwemakanika, bvunzo dze hydrostatic pressure, bvunzo dzisingaparadze, uye galvanized coating.

Maitiro Ekugadzira

JIS G 3454 STPG 370 inogona kugadzirwa uchishandisamusono or ERWmaitiro ekugadzira, pamwe chete nenzira dzakakodzera dzekupedzisa.

Pamusoro pekusimba kwekusimba, simba rekusimba, uye kureba kwataurwa pamusoro apa, kunewo bvunzo yekutsvedza uye kugona kupetwa.

Muedzo weKubata-bata: Kana daro riri pakati pemaplate maviri rasvika padaro rakatarwa H, hapafanire kuva nekukanganisika kana mitswe pamusoro pepombi yesimbi.

Kugona kukotama: Pombi inofanira kukotama 90° padhayamita yekunze yakapetwa katanhatu. Madziro epombi anofanira kunge asina zvikanganiso kana mitswe.

Kuedzwa kweHydrostatic kana Kuedzwa Kusingaparadze

Pombi yega yega yesimbi inoongororwa ne hydrostatic kana kuti kwete kukuvara kuti ionekwe kana paine zvikanganiso zvisingaonekwe nemaziso.

Kana kuongororwa kwe ultrasonic kuchishandiswa, kunofanirwa kunge kwakavakirwa pachiyero chakasimba kupfuura chiratidzo che UD class muJIS G 0582.

Kana kuyedzwa kwe eddy current kuchishandiswa, kunofanirwa kunge kwakavakirwa pachiyero chakasimba kupfuura chiratidzo chekirasi yeEY muJIS G 0583.

Yakagadzikwa

MuJIS G 3454, mapaipi esimbi asina kuputirwa anonzimapaipi matemauye mapaipi esimbi akarungwa anonzimapaipi machena.

Pombi chena: pombi yesimbi yakabatidzwa

Pombi nhema: pombi yesimbi isina galvanized

Maitiro emapombi machena ndeekuti mapaipi matema akakodzera anoputirwa nepfuti kana kupiswa kuti abvise tsvina pamusoro pepombi yesimbi uye ozoiswa galvanized ne zinc inosangana neJIS H 2107 standard yegiredhi 1 rinenge riri pasi. Zvimwe zvinhu zvinoitwa zvichienderana neJIS H 8641 standard.

Hunhu hwezinc coating hunoongororwa zvichienderana nezvinodiwa neJIS H 0401, Chinyorwa 6.

Nezvedu

Kubva payakavambwa muna 2014,Simbi yeBotopyava mutengesi anotungamira wemapaipi esimbi yekabhoni kuChamhembe kweChina, inozivikanwa nebasa rakanaka kwazvo, zvigadzirwa zvemhando yepamusoro, uye mhinduro dzakakwana.

Kambani iyi inopa mapaipi akasiyana-siyana esimbi yekabhoni nezvimwe zvigadzirwa zvinoenderana nazvo, zvinosanganisira mapaipi esimbi asina musono, ERW, LSAW, uye SSAW, pamwe chete nehurongwa hwakazara hwemapipi nemaflange. Zvigadzirwa zvayo zvehunyanzvi zvinosanganisirawo alloys dzemhando yepamusoro nesimbi dzisina ngura dzinogadzirwa neaustenitic, dzakagadzirirwa kusangana nezvinodiwa nemapurojekiti akasiyana-siyana emapaipi.
