Igurishwa rishyushye kubushinwa API 5L Umuyoboro wicyuma utagira umurongo (X42, X46, X52)
Incamake
Ibyo dukora byose mubisanzwe bifitanye isano nigitekerezo cyacu "Umukiriya ubanza, Kwizera mbere", dushishikajwe no gutanga imiyoboro ihanitse kandi yihuse yo gutanga imiyoboro idahwitse, Mugihe tugenda dutera imbere, duhanze amaso ibicuruzwa byacu bigenda byiyongera kandi tunatera imbere ku masosiyete yacu.
Twiyemeje guhaza ibyo ukeneye byose no gukemura ibibazo bya tekiniki ushobora guhura nabyo mubice byinganda. Ibicuruzwa byacu bidasanzwe nibisubizo hamwe nubumenyi bunini bwikoranabuhanga bituma duhitamo abakiriya bacu.
Ukurikije ibisabwa bisanzwe, ibisabwa kugirango imikorere yimiyoboro yicyuma iratandukanye, kandi ubushyuhe bwubushyuhe burashobora kugabanywa muburyo bukurikira:
1. Ubushyuhe buke (dogere 150-250)
Imiterere yabonetse kubushyuhe buke ni tempered martensite. Intego yacyo ni ukugabanya imihangayiko yimbere nubugome bwibyuma byazimye mugihe ukomeje ubukana bwinshi hamwe no kwihanganira kwambara kwinshi kwicyuma kizimye, kugirango wirinde guturika cyangwa kwangirika imburagihe mugihe ukoresheje. Ikoreshwa cyane cyane mubikoresho bitandukanye byo gukata karubone, ibikoresho byo gupima, imiyoboro yicyuma, imiyoboro izunguruka hamwe nibice bya karubisi, nibindi. Gukomera nyuma yubushyuhe ni HRC58-64.
2. Ubushyuhe bwo hagati (dogere 250-500)
Imiterere yabonetse kubushyuhe bwubushyuhe buringaniye ni troostite. Intego yacyo ni ukubona umusaruro mwinshi, imipaka igoye no gukomera. Kubwibyo, ikoreshwa cyane cyane mugutunganya imiyoboro itandukanye yicyuma nicyuma gishyushye, kandi ubukana nyuma yubushyuhe ni HRC35-50.
3. Ubushyuhe bwo hejuru (dogere 500-650)
Imiterere yabonetse kubushyuhe bwo hejuru irangwa na sorbite. Ubusanzwe, kuvura ubushyuhe bujyanye no kuzimya hamwe nubushyuhe bwo hejuru byitwa kuzimya no kuvura ubushyuhe, intego yabyo ni ukubona ibikoresho byubukanishi byuzuye imbaraga, ubukana, plastike nubukomere. Kubwibyo, ikoreshwa cyane mumamodoka, imiyoboro yicyuma, ibikoresho byimashini nibindi bice byingenzi byubatswe, nko guhuza inkoni, bolts, ibyuma na shitingi. Gukomera nyuma yo kurakara muri rusange HB200-330.
Gusaba
Umuyoboro ukoreshwa mu gutwara peteroli, amavuta n'amazi yavuye mu butaka mu nganda zikomoka kuri peteroli na gaze binyuze mu muyoboro

Ibisabwa
Ikizamini cya Hydrostatike
Umuyoboro kugirango uhangane n'ikizamini cya hydrostatike kidatemba binyuze mumasuderi cyangwa umubiri. Ihuriro ntirigomba gupimwa hydrostatike itanga ibice byakoreshejwe byageragejwe neza.
Ikizamini
Nta gucika kugaragara mugice icyo aricyo cyose cyikizamini kandi nta gufungura gusudira kuzabaho.
Ikizamini
Ibipimo byo kwemererwa gukora ikizamini giteganijwe ni:
- Imiyoboro ya EW D <12.750 muri:
- X60 hamwe na T 500in. Ntabwo hazabaho gufungura gusudira mbere yuko intera iri hagati yisahani iri munsi ya 66% yumwimerere wa diameter. Ku byiciro byose no kurukuta, 50%.
- Ku muyoboro ufite D / t> 10, ntihazabaho gufungura gusudira mbere yuko intera iri hagati yisahani iri munsi ya 30% yumwimerere wa diameter.
- Kubindi binini reba API 5L yuzuye.
Ikizamini cya CVN kuri PSL2
Ingano nini ya PSL2 nini hamwe n amanota bisaba CVN. Umuyoboro utagira ikizinga ugomba gupimwa mumubiri. Umuyoboro wo gusudira ugomba gupimwa mumubiri, gusudira imiyoboro hamwe na zone yibasiwe nubushyuhe. Reba kuri API 5L yuzuye ibisobanuro ku mbonerahamwe yubunini n'amanota kandi bisabwa imbaraga zingirakamaro.
