ASTM A335 Umuyoboro udafite ibyuma
Ibisobanuro bigufi:
ASTM A335 bakunze kwita umuyoboro wa chrome moly kubera imiti irimo Molybdenum (Mo) na Chromium (Cr).Molybdenum yongerera imbaraga ibyuma na Chromium (cyangwa chrome) nikintu cyingenzi kigizwe nicyuma.Ibigize chrome moly alloy umuyoboro wibyuma bituma biba byiza gukoreshwa mumashanyarazi, inganda, inganda zikomoka kuri peteroli, hamwe na serivise zamavuta aho amazi na gaze bitwarwa mubushyuhe bukabije hamwe nigitutu.
Twiteguye gusangira ubumenyi bwacu bwo kwamamaza kwisi yose kandi turagusaba ibicuruzwa bikwiye kubiciro byo kugurisha bikabije.Ibikoresho bya Profi rero birakwereka igiciro cyiza cyamafaranga kandi twiteguye kubyaza umusaruro hamwe na ASTM A335Umuyoboro udafite ibyuma, Ubwiza nubuzima bwuruganda, Wibande kubyo abakiriya bakeneye ni isoko yo kubaho kwiterambere niterambere, Twubahiriza ubunyangamugayo nimyizerere myiza yo gukora, dutegereje kuza kwawe!

Kurwanya cyane guturika ku bushyuhe bwinshi hamwe n’umuvuduko mwinshi.
Birashobora gukoreshwa muri Hydrogen Sulfide Serivisi.
Kurwanya gucikamo ibitero bya hydrogène no kwinjiza.
Kurwanya sulfide ishyushye.
Irashobora gukoreshwa kuri NACE Porogaramu aho ibidukikije bikarishye biri munsi ya temp hamwe nigitutu.
Irashobora gukoreshwa muri NACE-MRO 175 Sour Service.
Nibyiza kubishobora guturika.
Irashobora guhangana nubushyuhe bwo hejuru hamwe na elastique nkeya.
Ubwoko bwibyuma bivanze bitwikiriwe na ASTM A335 - ASME SA335 ibisobanuro byakozwe hamwe nimbonerahamwe ya "P", kuva P5 kugeza P92.Icyiciro cya P11 / P22 na P91 / 92 gikunze kuboneka mumashanyarazi, mugihe icyiciro cya P5 na P9 gikunze gukoreshwa mubikorwa bya peteroli.Icyiciro P9, P91 kiri, kurutonde, bihenze cyane

Umuyoboro wa Alloy Steel ukoreshwa ubushyuhe kugirango ugere kumiterere yubukanishi ukurikije ikintu cyifuzwa.Hano hari bumwe muburyo bwo kuvura ubushyuhe.
Kora ibisanzwe no kuzimya.
Kuzimya no Kuringaniza.
Gusanzwe & Gukomera.
Transvers / longitudinal: guhagarika umutima no gusibanganya, gukomera, kugerageza kugoreka- kubintu byakorewe ubushyuhe mu itanura ryicyiciro, ibi bizamini bizakorwa kuri 5% yimiyoboro iva kuri buri mubare wubushyuhe.Kubufindo buto, umuyoboro umwe byibuze ugomba kugeragezwa.
ASTM A335 Gr.P91 igomba kugira ubukana bwa 250 HB / 265 HV (25 HRC).
Igeragezwa rya Hydro: bizashyirwa muburebure bwa pipe.
