Q10: Ese mutanga impera zikozwe mu mabuye y'agaciro hamwe n'amavuta ya 904L?
A: Yego. Dushobora gutegura imiyoboro (30-35°, 1.6 mm hasi) hanyuma tugashyiraho amavuta ya Alloy 625 cyangwa 904L ku ruhande rw'imiyoboro. Ibi birinda ko 904L igabanuka mu gihe cyo gusudira mu murima.

Q11: Ese ushobora gutanga imiyoboro ya U-bend ihindura ubushyuhe ya 904L?
A: Yego, ku muyoboro udafite umugozi (OD ≤168 mm). Dupfunyika ubukonje, tugakuraho imihangayiko, kandi tugapfunyika 100% NDT (PT cyangwa ET). Imiterere ya U-impeta yo gutanga serivisi za aside ikunze kugaragara mu bimera bya shimi.

Q12: Nigute natumiza umubare muto w'igerageza?
A: Tanga OD, Uburemere bw'ibanze, ubugari bw'icyuma gipfundikiye, uburebure (m), n'urwego rw'icyuma gifashe inyuma. Tuzatanga urugero rw'igerageza (urugero, metero 50 kugeza 100). Tegereza igiciro cy'igiciro ku bipimo bike.

9. Urutonde rw'ibyo gutumiza umuyoboro wa 904L Clad

Kugira ngo urebe neza ko ibipimo ari byo, nyamuneka tanga ibi bikurikira:

●Icyuma gikozwe mu gikoresho cy'icyuma gishyigikiwe(API 5L X52 / 60/65, SA-106 Gr.B, SA-210 Gr.C, A333 Gr.6, cyangwa A335 P11 / P22)

● Umurambararo wo hanze (OD)naubugari bw'urukuta rw'ibanze

● Ubugari bw'igipfundikizo cya 904L(ndasaba mm 3.0 kugira ngo ikoreshwe mu gutanga aside)

● Uburebure kuri buri gicenauburebure bwose (metero)

● Uburyo bwo gukora(yasudeshejwe kuri OD ≥219 mm; idasobekeranye kuri OD ≤168 mm)

● Igipimo ngenderwaho gikurikizwa(API 5LD, ASME, EN, cyangwa imiterere y'umukiriya)

● Urwego rw'igenzura(Ubwoko bwa 3.1 busanzwe; Ubwoko bwa 3.2 n'undi muntu)

● Gusoza kurangiza.

● Igihe cyo gutanga(Icyambu cya FOB mu Bushinwa, icyambu cya CIF cyo kugeramo)
