Omaka bomkhiqizo

Yini i-STPG 370 Pipe Material?

I-STPG 370 iyibanga lepayipi lensimbi elinekhabhoni ephansi elicaciswe kuzinga lase-Japan i-JIS G 3454.

I-STPG 370 inamandla amancane okudonsa angu-370 MPa kanye namandla amancane okukhiqiza angu-215 MPa.

I-STPG 370 ingakhiqizwa njengamashubhu ensimbi angenamthungo noma amashubhu ensimbi ashiselwe kusetshenziswa inqubo yokushisela ukumelana nogesi (ERW).Ilungele ukusetshenziswa ezinhlelweni zamapayipi okucindezelayo namazinga okushisa afinyelela ku-350°C.

Okulandelayo, sizobheka i-STPG 370 kusukela ezinqubweni zokukhiqiza, ukwakheka kwamakhemikhali, izakhiwo zemishini, ukuhlolwa kwengcindezi ye-hydrostatic, ukuhlolwa okungabhubhisi, kanye nokunamathela okufakwe uthayela.

Inqubo Yokukhiqiza

I-JIS G 3454 STPG 370 ingakhiqizwa kusetshenziswa iengenamthungo or ERWinqubo yokukhiqiza, ehlanganiswe nezindlela ezifanele zokuqeda.

EC: Ukuphikiswa kukagesi okuqediwe okubandayo okushiselwe ipayipi lensimbi;

EG: Ukumelana nogesi okushiselwe ipayipi lensimbi ngaphandle kwalawo aphelile ashisayo naqediwe abandayo.

Ukwakheka Kwamakhemikhali

I-JIS G 3454ivumela ukungezwa kwezakhi zamakhemikhali ezingekho etafuleni.

I-STPG 370 iyinsimbi enekhabhoni ephansi ngokokwakheka kwayo kwamakhemikhali.Ukwakheka kwayo kwamakhemikhali kuklanyelwe ukuyivumela ukuthi isetshenziswe ezindaweni ezingeqile ku-350°C, enamandla amahle, ukuqina, nokumelana nezinga lokushisa eliphezulu.

Ngaphezu kwamandla okuqina, amandla aqinile, kanye nobude obushiwo ngenhla, kukhona nokuhlolwa okucaba nokugoba.

Ukuhlola Ukucaba: Lapho ibanga eliphakathi kwamapuleti amabili lifinyelela ebangeni elishiwo H, akumele kube namaphutha noma imifantu ebusweni bepayipi lensimbi.

Ukugoba: Ipayipi kufanele igotshwe ngo-90 ° endaweni engaba izikhathi eziyisi-6 ububanzi bayo obungaphandle.Udonga lwamapayipi akumele lungabi nasici noma imifantu.

Ukuhlolwa kwe-Hydrostatic noma Ukuhlolwa Okungonakalisi

Ipayipi ngalinye lensimbi lingaphansi kokuhlolwa kwe-hydrostatic noma ukuhlolwa okungabhubhisi ukuze kuhlolwe noma yikuphi ukukhubazeka okungabonakali ngeso lenyama.

Ukuhlolwa kwe-Hydrostatic

Ngokwezinga elihleliwe lokuqina kodonga lwepayipi lensimbi, khetha inani elifanele lokucindezela kwamanzi, ligcine okungenani imizuzwana emi-5, bese uhlola ukuthi ipayipi lensimbi liyavuza yini.

Ithebula lesisindo sepayipi lensimbi le-JIS G 3454 kanye neshejuli yePipe ingabukwa ngokuchofoza isixhumanisi esilandelayo:

· Ishadi Lesisindo Sepayipi Lensimbi le-JIS G 3454

· uhlelo 10,uhlelo 20,uhlelo 30,uhlelo 40,uhlelo 60, futhiuhlelo 80.

Ukuhlolwa Okungonakali

Uma kusetshenziswa ukuhlolwa kwe-ultrasonic, kufanele kusekelwe esimisweni esiqinile kunesiginali yekilasi le-UD ku-JIS G 0582.

Uma kusetshenziswa ukuhlolwa kwamanje kwe-eddy, kufanele kusekelwe ezingeni eliqine kakhulu kunesiginali yekilasi le-EY ku-JIS G 0583.

Kufakwe amagalani

Ku-JIS G 3454, amapayipi ensimbi angavaliwe abizwaamapayipi amnyamanamapayipi ensimbi abizwa ngokuthiamapayipi amhlophe.

Ipayipi elimhlophe: ipayipi lensimbi

Ipayipi elimnyama - ipayipi lensimbi elingavunyelwe

Ipayipi elimnyama: ipayipi lensimbi elingaphekiwe

Inqubo yamapayipi amhlophe iwukuthi amapayipi afanelekayo amnyama ayadutshulwa noma afakwe emanzini anosawoti ukuze asuse ukungcola ebusweni bepayipi lensimbi bese efakwa uthayela nge-zinc ehlangabezana nezinga le-JIS H 2107 okungenani lebanga loku-1. Ezinye izindaba ziyenziwa. ngokuhambisana nezinga le-JIS H 8641.

Izici zokumboza i-zinc ziyahlolwa ngokuhambisana nezidingo ze-JIS H 0401, Isigaba 6.

Mayelana NATHI

Kusukela yasungulwa ngo-2014,Insimbi ye-Botopisibe ngumphakeli ohamba phambili wepayipi lensimbi ye-carbon eNyakatho yeChina, elaziwa ngomsebenzi omuhle kakhulu, imikhiqizo yekhwalithi ephezulu, nezixazululo ezibanzi.

Le nkampani inikeza izinhlobonhlobo zamapayipi ensimbi ye-carbon nemikhiqizo ehlobene, okuhlanganisa ipayipi lensimbi engenamthungo, i-ERW, i-LSAW, ne-SSAW, kanye nohlu oluphelele lokufakwa kwamapayipi nama-flange.Imikhiqizo yayo ekhethekile ihlanganisa ama-alloys asezingeni eliphezulu kanye nezinsimbi ezingenasici ze-austenitic, ezenzelwe ukuhlangabezana nezidingo zamaphrojekthi ahlukahlukene wamapayipi.
