Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Iyini i-STPG 370 Pipe Material?

I-STPG 370 iyizinga lepayipi lensimbi ephansi echazwe ku-JIS G 3454 ejwayelekile yaseJapan.

I-STPG 370 inamandla okudonseka okungenani angu-370 MPa kanye namandla okukhiqiza okungenani angu-215 MPa.

I-STPG 370 ingakhiqizwa njengamashubhu ensimbi angenamthungo noma amashubhu ensimbi ahlanganisiwe kusetshenziswa inqubo yokushisela yokumelana kagesi (i-ERW). Ifanele ukusetshenziswa ezinhlelweni zamapayipi okucindezela anezinga lokushisa lokusebenza elifinyelela ku-350°C.

Okulandelayo, sizobheka i-STPG 370 kusukela ezinqubweni zokukhiqiza, ukwakheka kwamakhemikhali, izakhiwo zemishini, ukuhlolwa kokucindezela kwe-hydrostatic, ukuhlolwa okungonakalisi, kanye nokugqoka okwenziwe nge-galvanized.

Inqubo Yokukhiqiza

I-JIS G 3454 STPG 370 ingakhiqizwa kusetshenziswangaphandle komthungo or I-ERWinqubo yokukhiqiza, kuhlanganiswe nezindlela ezifanele zokuqeda.

I-EG: Ipayipi lensimbi elihlanganisiwe elinokumelana nogesi ngaphandle kwaleli eliqediwe ngokushisa kanye neliqediwe ngokushisa.

Ukwakheka Kwamakhemikhali

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

I-STPG 370 iyinsimbi ekhabhoni ephansi ngokwesakhiwo sayo samakhemikhali. Ukwakheka kwayo kwamakhemikhali kwenzelwe ukuthi isetshenziswe ezindaweni ezingadluli ku-350°C, enamandla amahle, ukuqina, kanye nokumelana nokushisa okuphezulu.

Ngaphezu kwamandla okudonsa, amandla okudonsa, kanye nokwelulwa okukhulunywe ngakho ngenhla, kukhona nokuhlolwa kokuthamba kanye nokugoba.

Ukuhlolwa Kokuthamba: Uma ibanga eliphakathi kwamapuleti amabili lifika ebangeni elishiwo u-H, akumele kube khona iziphambeko noma imifantu ebusweni bepayipi lensimbi.

Ukugoba: Ipayipi kufanele ligotshwe ngama-90° ku-radius ephindwe kasithupha ububanzi bayo bangaphandle. Udonga lwepayipi kumele lungabi namaphutha noma imifantu.

Ukuhlolwa Okungashintshi Noma Okungabhubhisi

Ipayipi ngalinye lensimbi lihlolwa nge-hydrostatic noma ukuhlolwa okungabhubhisi ukuze kuhlolwe noma yiziphi iziphambeko ezingabonakali ngeso lenyama.

Ukuhlolwa Kwamanzi

Ngokwezinga elihleliwe lobukhulu bodonga lwepayipi lensimbi, khetha inani lokucindezela kwamanzi elifanele, uligcine okungenani imizuzwana emi-5, bese uhlola ukuthi ipayipi lensimbi liyavuza yini.

Ukuhlolwa Okungabhubhisi

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

Uma kusetshenziswa ukuhlolwa kwe-eddy current, kufanele kusekelwe kuzinga eliqinile kunesignali yekilasi le-EY ku-JIS G 0583.

I-Galvanised

Ku-JIS G 3454, amapayipi ensimbi angagqokwanga abizwa ngokuthiamapayipi amnyamafuthi amapayipi ensimbi agqitshiwe abizwa ngokuthiamapayipi amhlophe.

Ipayipi elimhlophe: ipayipi lensimbi elenziwe nge-galvanized

Ipayipi elimnyama - ipayipi lensimbi elingagqwali

Ipayipi elimnyama: ipayipi lensimbi elingagayiwe

Inqubo yamapayipi amhlophe ukuthi amapayipi amnyama afanelekile aqhunyiswe ngokudubula noma afakwe usawoti ukuze kususwe ukungcola ebusweni bepayipi lensimbi bese ehlanganiswa nge-zinc ehlangabezana nezinga le-JIS H 2107 okungenani lebanga loku-1. Ezinye izinto zenziwa ngokuhambisana nezinga le-JIS H 8641.

Izici zomphetho we-zinc ziyahlolwa ngokuhambisana nezidingo ze-JIS H 0401, Isigaba 6.

Mayelana NATHI

Selokhu yasungulwa ngo-2014,Insimbi yeBotopisibe ngumhlinzeki ohamba phambili wamapayipi ensimbi yekhabhoni eNyakatho yeShayina, eyaziwa ngenkonzo enhle kakhulu, imikhiqizo esezingeni eliphezulu, kanye nezixazululo eziphelele.

Le nkampani inikeza amapayipi ahlukahlukene ensimbi yekhabhoni kanye nemikhiqizo ehlobene nayo, kufaka phakathi ipayipi lensimbi elingenamthungo, i-ERW, i-LSAW, kanye ne-SSAW, kanye nohlu oluphelele lwezihlanganisi zamapayipi nama-flange. Imikhiqizo yayo ekhethekile ifaka phakathi ama-alloy ebanga eliphezulu kanye nezinsimbi ezingagqwali ze-austenitic, ezenzelwe ukuhlangabezana nezidingo zamaphrojekthi ahlukahlukene amapayipi.
