Okujwayelekile: ASTM A500 (ASME SA500)
Inhloso eyinhloko: ugesi, uphethiloli, izinkampani zamakhemikhali, izinga lokushisa eliphezulu, ukumelana nokushisa okuphansi, amasistimu amapayipi angagqwali.
Imikhiqizo eyinhloko yensimbi / yensimbi grade: Gr.A;Gr.B;Gr.C.
Imininingwane: OD :10.3-820 mm, ukujiya kodonga: 0.8 kuya ku-75 mm, Ubude: 6m, Ngaphezu kwalokho, ngokusekelwe ezidingweni zamakhasimende, ezinganikeza amanye amamaki kanye nokucaciswa kwepayipi lensimbi.
Ukucubungula: insimbi kufanele ihambisane nokucutshungulwa okukodwa noma ngaphezulu: indawo evulekile, umoya ophefumulayo, noma ukwenza insimbi yesithando somlilo kagesi, ukukhishwa kwamamaki ahlukene ensimbi ngokulandelana, abakhiqizi bensimbi kufanele banqume into ephakathi besebenzisa izinqubo ezivamile ezisusiwe, i-clean ecacile. ukuhlukaniswa kwezinga.
Ukukhiqiza: kukhiqizwa ngokungenamthungo nomaipayipi lensimbi elishiselwe, ipayipi elishiselwe ngokugoqa okwenziwe yi-resistance welding.Amandla okuklama kwesakhiwo sesiqondiso se-longitudinal sepayipi, i-docking application tube yindlela yokunquma ukushuba kwayo ukushisela.

I-ASTM A520
Ukucaciswa Okujwayelekile kwe-ASTM A520 Kwezimfuneko Ezingeziwe Zemikhiqizo Yeshubhu Yensimbi Yensimbi Engenamthungo kanye Nekagesi-Ukumelana ne-Welded Yesevisi Yezinga Lokushisa Eliphezulu Evumelana Nezincomo ze-ISO Zokwakhiwa Kwebhoyili.
Lokhu kucaciswa kunikeza izimfuneko okuwukuthi zengeze futhi zidlule izimfuneko zokucaciswa kwe-ASTM zemikhiqizo ye-carbon steel tubular engenamthungo kanye ne-electric-resistance-welded elungele isevisi yezinga lokushisa eliphezulu, lapho le mikhiqizo yamashubhu izosetshenziswa ezinhlelweni ezihambisana nemithetho ye-ISO.Ukucaciswa kweshubhu okungase kubize lokhu kucaciswa yilezi: Ipayipi Lensimbi Elingenamthungo Lekhabhoni Yesevisi Yezinga Lokushisa Eliphezulu A 106 Electric-Resistance-Welded Carbon Steel Boiler Tubes A 178/A 178M 178M Seamless Carbon Steel Boiler Tubes for High-Pressure Service A 192/A 192M 192M I-Seamless Medium-Carbon Steel Boiler kanye ne-Superheater Tubes A 210/A 210M 210M Electric-Resistance-Welded Carbon Steel Boiler kanye ne-A 226 Superheater Tubes Yesevisi Yokucindezela Okuphezulu.Amanani ashiwo ngamayunithi ayintshi yephawundi kufanele abhekwe njengezinga elijwayelekile.
