11. Uburyo bwo gukora:
- Umuyoboro wakozwe hifashishijwe uburyo bukonje kandi bwihuta cyane bwo gusudira (HFIW).
- Igice cyakozwe muburyo bwa tubular kandi gisudira igihe kirekire ukoresheje gusudira inshuro nyinshi.
12. Kugenzura no Kwipimisha:
- Isesengura ryimiti yibikoresho fatizo
- Hindura ikizamini cya tensile kugirango umenye neza imashini zikurikiza ibisobanuro
- Ikizamini cyo gusibanganya kugirango umenye ubushobozi bwumuyoboro wo guhangana na deformasiyo
- Ikizamini cyo gushinga imizi (amashanyarazi fusion welds) kugirango umuyoboro uhinduke kandi ubuziranenge
- Ikizamini cya Hydrostatike kugirango umenye neza ko umuyoboro utemba
13. Ikizamini kidasenya (NDT):
Kwipimisha Ultrasonic (UT)
- Eddy igeragezwa (ET)
14. Icyemezo:
- Icyemezo cyo gupima urusyo (MTC) ukurikije EN 10204 / 3.1
- Igenzura ryabandi bantu (bidashoboka)
15. Gupakira:
- Muri bundles
- Ingofero ya plastike kumpande zombi
- Impapuro zidafite amazi cyangwa igipfundikizo cyicyuma
- Ikimenyetso: nkuko bisabwa (harimo uwabikoze, amanota, ingano, bisanzwe, umubare wubushyuhe, Umubare wa Lot nibindi)
16. Imiterere yo gutanga:
- Nkuko bizunguruka
- Bisanzwe
- Bisanzwe bizunguruka
17. Ikimenyetso:
- Buri muyoboro ugomba gushyirwaho ibimenyetso byemewe namakuru akurikira:
- Izina ryumukoresha cyangwa ikirango
- SANS 719 Icyiciro C.
- Ingano (diameter yo hanze n'ubugari bw'urukuta)
- Shyushya numero cyangwa icyiciro
- Itariki yakozwe
- Kugenzura no gusuzuma ibyemezo birambuye
18. Ibisabwa bidasanzwe:
- Imiyoboro irashobora gutangwa hamwe nudusanduku twihariye cyangwa imirongo ikoreshwa muburyo bwihariye (urugero, epoxy coating yo kurwanya ruswa).
19. Ibizamini by'inyongera (Niba bikenewe):
- Charpy V-ikizamini cyingaruka
- Ikizamini gikomeye
- Ikizamini cya Macrostructure
- Ikizamini cya Microstructure
20.Kwihanganirana:
-Hanze ya Diameter
-Ubugari bwose
Ubunini bw'urukuta rw'umuyoboro bugomba, bitewe no kwihanganira +10% cyangwa -8%, bigomba kuba imwe mu ndangagaciro zifatika zitangwa mu nkingi ya 3 kugeza ku ya 6 y'imbonerahamwe iri munsi, keretse iyo byumvikanyweho ukundi hagati y'uwabikoze n'abaguzi.
-Uburinganire
Gutandukana kwumuyoboro uva kumurongo ugororotse, ntibishobora kurenga 0,2% yuburebure bwumuyoboro.
Ikintu cyose kitari kizengurutse (usibye icyatewe na sag), cy'imiyoboro ya diameter yo hanze irenga mm 500 ntishobora kurenza 1% ya diameter yo hanze (iemaximum ovality 2%) cyangwa mm 6, iyo ari nto.
Nyamuneka menya ko urupapuro rurambuye rutanga amakuru yuzuye kubyerekeyeSANS 719 Imiyoboro ya C..Ibisabwa byihariye birashobora gutandukana ukurikije umushinga nibisobanuro nyabyo byumuyoboro usabwa.
