11. Inqubo Yokukhiqiza:
- Ipayipi lakhiwe kusetshenziswa inqubo ye-welded induction induction (HFIW) eyakhiwe ngendlela ebandayo kanye ne-high-frequency induction welded (HFIW).
- I-strip yakhiwe ibe yisimo se-tubular futhi ishiselwe ngobude kusetshenziswa i-high-frequency induction welding.
12. Ukuhlola Nokuhlola:
- Ukuhlaziywa kwamakhemikhali kwempahla eluhlaza
- Ukuhlolwa kwe-Transverse tensile ukuqinisekisa ukuthi izakhiwo zemishini ziyahambisana nokucaciswa
- Ukuhlolwa kokucaba ukuze kuqinisekiswe ikhono lepayipi ukumelana nokuguquguquka
- Ukuhlolwa kokugoba kwezimpande (ama-weld fusion kagesi) ukuze kuqinisekiswe ukuguquguquka kwepayipi nobuqotho
- Ukuhlolwa kwe-Hydrostatic ukuze kuqinisekiswe ukuvuza kwepayipi
13. Ukuhlola Okungabhubhisi (NDT):
- Ukuhlolwa kwe-Ultrasonic (UT)
- Ukuhlolwa kwamanje kwe-Eddy (ET)
14. Isitifiketi:
- Isitifiketi sokuhlolwa kweMill (MTC) ngokuya nge-EN 10204/3.1
- Ukuhlolwa komuntu wesithathu (kuyakhetheka)
15. Ukupakisha:
- Ngezinqwaba
- Amakepisi epulasitiki kuzo zombili iziphetho
- Iphepha elingangeni manzi noma ikhava yeshidi lensimbi
- Ukumaka: njengoba kudingekile (kuhlanganise Umkhiqizi, ibanga, usayizi, izinga, inombolo yokushisa, Inombolo Yelotho njll.)
16. Isimo sokudiliva:
- Njengoba igoqwe
- Kujwayelekile
- Kugoqiwe ngokujwayelekile
17. Ukumaka:
- Ipayipi ngalinye kufanele limakwe ngokusemthethweni ngolwazi olulandelayo:
- Igama lomkhiqizi noma uphawu lokuhweba
- SANS 719 Grade C
- Usayizi (ububanzi bangaphandle nokuqina kodonga)
- Inombolo yokushisa noma inombolo ye-batch
- Usuku lokukhiqiza
- Imininingwane yesitifiketi sokuhlolwa kanye nesitifiketi
18. Izidingo Ezikhethekile:
- Amapayipi angahlinzekwa ngezimbobo ezikhethekile noma ama-linings ukuze asetshenziswe okuthile (isb., i-epoxy coating yokumelana nokugqwala).
19. Ukuhlola Okwengeziwe (Uma Kudingeka):
- Ukuhlolwa komthelela we-Charpy V-notch
- Ukuhlolwa kokuqina
- Ukuhlolwa kwe-Macrostructure
- Ukuhlolwa kwe-Microstructure
20.Ukubekezela:
-Ububanzi bangaphandle
-Ukujiya kwezindonga
Ukuqina kodonga lwepayipi, kuncike ekubekezeleleni okungu-+10 % noma -8 %, kube ngelinye lamanani afanelekile anikezwe kukholamu 3 kuya ku-6 wethebula elingezansi, ngaphandle uma kuvunyelwene ngenye indlela phakathi komkhiqizi nomthengi.
-Ukuqondisa
Noma yikuphi ukuchezuka kwepayipi emgqeni oqondile akumele kudlule u-0,2 % wobude bepayipi.
Noma yikuphi ukuphuma kwendingilizi (ngaphandle kwalokho okubangelwa ukuxega), kwamapayipi anobubanzi obungaphezulu kuka-500 mm akumele kudlule u-1 % wobubanzi obungaphandle (okungukuthi i-ovality enkulu engu-2 %) noma u-6 mm, kuye ngokuthi yikuphi okuncane.
Sicela uqaphele ukuthi leli shidi ledatha elinemininingwane linikeza ulwazi olunzulu mayelanaSANS 719 Grade C amapayipi.Izidingo ezithile zingase zihluke ngokusekelwe kuphrojekthi kanye nokucaciswa okuqondile kwepayipi edingekayo.
