I-JIS G 3454iyindinganiso yezimboni yaseJapan yamapayipi ensimbi ye-carbon kumasistimu okucindezela anezinga lokushisa eliphakeme lokusebenza elingu-350°C.Izinga lihlanganisa amabanga amabili:I-STPG 370futhiI-STPG 410.Kusebenza kumapayipi angangeni kagesi ashiselwe (ERW) noma amapayipi angenamthungo anobubanzi obungu-10.5 mm kuya ku-660.4 mm (okungukuthi 6A kuya ku-650A, noma 1/8B kuya ku-26B).
I-JIS G 3454 Amapayipi ensimbi azokwenziwa kusetshenziswa inhlanganisela efanele yezindlela zokukhiqiza amapayipi ensimbi nezindlela zokuqeda kuthebula elingezansi.

SC: Ipayipi lensimbi engenamthungo elipholile eliqediwe;
EH: Ipayipi lensimbi elishisiwe elishisiwe elishisiwe;

EG: Ukumelana nogesi okushiselwe ipayipi lensimbi ngaphandle kwalawo aphelile ashisayo naqediwe abandayo.
Insimbi ye-Botopingumkhiqizi kanye nomphakeli wamapayipi ensimbi ensimbi ashiselwe esezingeni eliphezulu avela eChina, kanye nesitoko samapayipi ensimbi angenamthungo.Uma unezidingo, sicela ukhululeke ukuxhumana nathi futhi sizokunikeza ukwesekwa kwamahhala kochwepheshe.

Ukuhlola Ukucaba
Lapho ibanga eliphakathi kwamapuleti amabili lifinyelela ebangeni elishiwo H, akumele kube namaphutha noma imifantu ebusweni bepayipi lensimbi.
Ngamashubhu ensimbi angenamthungo: H = (1+e) t/(e + t/D);
Emapayipi ensimbi e-ERW: H = 1/3 D (ye-weld) noma i-H = 2/3 D (ngengxenye ngaphandle kokushisela);
H: ibanga phakathi kwamapuleti aphansi (mm);
е: kuchazwa njalo ngakunye ebangeni ngalinye lepayipi, 0.08 ye-STPG 370, 0.07 ye-STPG 410;
t: ukujiya kodonga lwepayipi (mm);
D: ububanzi obungaphandle bepayipi (mm);
Ukuhlolwa Kokwenza Isicaba sisebenza kumapayipi ensimbi anobubanzi obujwayelekile obungaphezu kuka-40A (48.6mm).
Ukugoba
Ukugobeka kusebenza kumapayipi anobubanzi obungu-40 A (48.6) noma obuncane.
Ipayipi kufanele igotshwe ngo-90 ° endaweni engaba izikhathi eziyisi-6 ububanzi bayo obungaphandle.Udonga lwamapayipi akumele lungabi nasici noma imifantu.
Ipayipi ngalinye lensimbi kufanele lihlolwe ingcindezi ye-hydrostatic noma ukuhlolwa okungabhubhisi.
Ukuhlolwa kwe-Hydrostatic
Gcina ingcindezi ethile okungenani imizuzwana emi-5 ngaphandle kokuvuza.
Inani lokucindezela lihlobene neshejuli No. yepayipi lensimbi.

I-JIS G 3454 Ukubekezelela ububanzi bangaphandle, ukujiya kodonga, ukugqama, nobude kuzohlangabezana nezidingo ezilandelayo.
Kusukela yasungulwa ngo-2014, i-Botop Steel isiphenduke umhlinzeki oholayo wepayipi lensimbi eNyakatho neChina, elaziwa ngomsebenzi omuhle kakhulu, imikhiqizo yekhwalithi ephezulu, nezisombululo 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.
Sicela usithinte, sizokunikeza izinga eliphezulu, amapayipi ensimbi ajwayelekile anenkonzo yobungcweti nephumelelayo.UBotop ubheke ngabomvu ukukusiza.
