- I-strip yakhiwa ngesimo se-tubular futhi i-welded endeitudinally isebenzisa ukufuduka okuthe xaxa okuphezulu.
12. Ukuhlola nokuhlola:
- Ukuhlaziywa kwamakhemikhali kwezinto ezingavuthiwe
- Ukuhlolwa kweTensile kweTransverse ukuqinisekisa izakhiwo zemishini zihambisana nokucaciswa
- Ukuhlolwa kwe-Flattening ukuqinisekisa amandla wepayipi lokumelana nezimomo
- Ukuhlolwa kwe-Root Bend (Ama-Weld e-Fusion Egesi) ukuqinisekisa ukuguquguquka kwepayipi nobuqotho
- Ukuhlolwa kweHydrostatic ukuqinisekisa ukuqina kokuvuza kwepayipi
13. Ukuhlolwa okungelonakalisi (NDT):
- Ukuhlolwa kwe-Ultrasonic (ut)
- Ukuhlolwa kwamanje kwangaphambi kwesikhathi (et)
14. Isitifiketi:
- Isitifiketi sokuhlola i-MIL (MTC) ngokusho kwe-EN 10204 / 3.1

- Izigqoko zepulasitiki zombili iziphetho
- Iphepha elingangeni manzi noma ikhava yensimbi yensimbi
- Ukumaka: njengoba kudingeka (kufaka phakathi umenzi, ibanga, usayizi, okujwayelekile, inombolo yokushisa, inombolo yeningi njll.)
16. Isimo sokulethwa:
- Njengoba kugoqwe
- ejwayelekile
- Ukongwe ngokwejwayelekile
17. Ukumaka:
- Ipayipi ngalinye kufanele libhalwe ngokusemthethweni ngolwazi olulandelayo:
- Igama Lomenzi noma uphawu lwentengiso
- Sans 719 Ibanga C
- Usayizi (ububanzi obungaphandle nobukhulu bodonga)
- Inombolo yokushisa noma inombolo ye-batch
- Usuku lokukhiqiza
- Imininingwane yesitifiketi sokuhlola neyokuhlola
18. Izidingo ezikhethekile:
- Amapayipi angahlinzekwa ngezimbali ezikhethekile noma ama-linings ngezinhlelo ezithile (isib. Ukuhlanganiswa kwe-epoxy kokumelana nokugqwala).
19. Ukuhlolwa okwengeziwe (uma kudingeka):
- Isivivinyo se-Charpy V-Notch
- Ukuhlolwa kobulukhuni
- Ukuhlolwa kwe-macrostrupture
- Ukuhlolwa kwe-micructure
20.Kwendla:
I-Coumpeter ye-STIDE
Ubukhulu obukhulu
Ubukhulu bodonga lwepayipi buyakubekezelelana no- + 10% noma -8%, yiba ngenye yamanani afanelekile anikezwe kumakholomu ama-3 kuye kwayisithupha kwetafula lomthengi kanye nomthengi.
-I -straightness
Noma yikuphi ukuphambuka kwepayipi kusuka kulayini oqondile, ngeke kudlule u-0,2% wobude bepayipi.
Noma yikuphi ukujikeleza (ngaphandle kwalokhu okubangelwa yi-SAG), yamapayipi angaphandle kobubanzi obukhulu ngaphezu kwama-500 mm ngeke adlule i-1% ye-aftic ububanzi (iemaximum Ofmallial 2%) noma i-6 mm, noma ngabe yikuphi okuncane.
Sicela wazi ukuthi le shidi ledatha enemininingwane linikeza imininingwane ephelele mayelanaAmapayipi we-Sans 719 Amapayipi. Izidingo ezithile zingahluka ngokuya ngephrojekthi kanye nokucaciswa ngqo kwepayipi okudingekayo.
