Umbuzo 17: Ingabe ninikeza i-PMI (Ukuhlonza Izinto Ezinhle) ku-cladding engu-316L?
A: Yebo. Singenza i-XRF ezindaweni eziningana eceleni kwepayipi ngalinye, futhi sifake umbiko kufayela lekhwalithi. Kukhona inkokhelo encane ngepayipi ngalinye kuma-oda amakhulu.
Umbuzo 18: Ingabe ipayipi elimboziwe linganikezwa ngeziphetho ezigobile kanye nebhotela le-CRA?
A: Yebo. I-angle ejwayelekile ye-bevel engu-30-35° kanye nokufika okungu-1.6 mm. I-CRA buttering (2-3 mm ye-Alloy 625 noma i-316L filler ebusweni be-bevel) iyatholakala ukuvimbela ukuncibilika ngesikhathi sokushisela ensimini. Lokhu kunconywa ikakhulukazi kuma-weld e-girth lapho kusetshenzwa ngomfutho ophezulu.
Q19: Uyini ulwazi lwakho ngokuhlinzeka ngamapayipi ambozwe ngogesi angu-316L ngokwezindinganiso ze-European EN?
A: Sivame ukunikeza i-EN 10216-2 (engemuva) nge-cladding engu-1.4404 (316L). Singanikeza izitifiketi ze-EN 10204 3.2 ezinobufakazi be-TÜV kanye nesimemezelo se-PED. Ama-oda amaningi aye eJalimane, eNetherlands, eFrance nase-UK.
Umbuzo 20: Ungabelana ngezinkomba zepayipi elikhulu elimbozwe ngobubanzi obungu-316L (API 5L X65+316L)?
A: Yebo, sinikeze ipayipi elimboziwe le-X65+316L (OD 610mm, elimboziwe elingu-2.5mm) lephrojekthi yokujova i-CO₂ yaseMpumalanga Ephakathi (ipayipi elingu-200 km). Izinkomba ziyatholakala ku-NDA.
9. Usizo Loku-oda – Indlela Yokuchaza Ipayipi Elimboziwe Elingu-316L
Ukuqinisekisa ukuthi uthola inhlanganisela efanele, sicela unikeze okulandelayo ngento ngayinye yomugqa:
1. Ibanga lensimbi elisekelayo(khetha ku-SA-210 Gr.C, SA-106 Gr.B, API 5L X52/60/65, A333 Gr.6, A335 P11/P22)
2. Ububanzi bangaphandle (OD)futhiukujiya kodonga oluyinhloko
3. Ubukhulu be-cladding obungu-316L(ngokuvamile 1.5-3.5 mm)
4. Ubude obubodwa(m) kanye nobude obuphelele (noma ubuningi)
5. Izinga elisebenzayo(I-ASME, i-API, i-EN, noma incazelo yephrojekthi)
6. Isitifiketi esidingekayo(EN 10204 Uhlobo 3.1 olujwayelekile; Uhlobo 3.2 olukhethwayo)
7. Ukuhlolwa okwengeziwe(I-Charpy, ukugqwala kwe-intergranular, i-NACE, i-creep, njll.)
8. Ukuqeda kokuphela(okucacile, okugobile, okugobile + okunongiwe)
