    ASTM A139 S235 J0 Imiyoboro y'icyuma

    ASTM A139 S235 J0 Imiyoboro Yicyuma Cyerekanwe Ishusho
    • ASTM A139 S235 J0 Imiyoboro y'icyuma

    Ibisobanuro bigufi:

    Kumenyekanisha udushya twagezweho muburyo bwa tekinoroji yicyuma - S235 J0 Umuyoboro wicyuma.Iki gicuruzwa cyakozwe hifashishijweASTM A139 ibipimo kugirango harebwe ubwubatsi buhanitse kandi bukore neza.Uburyo bwo gukora ibyuma bizunguruka bikoreshwa mubikorwa byayo bituma habaho ihinduka rimwe ryicyuma, guhangayikishwa cyane n’ibisigara, hamwe nubuso bworoshye butarimo gushushanya.

    Ibicuruzwa

    Imwe mu nyungu zingenzi zaS235 J0 umuyoboro w'icyumani ihinduka ryayo muri diameter hamwe nuburebure bwurukuta.Ibi bituma habaho ibikorwa byinshi byo guhuza n'imihindagurikire y'ikirere, cyane cyane mu gukora imiyoboro yo mu rwego rwo hejuru, ikikijwe n'inkuta.Byongeye kandi, ikoranabuhanga rifite akamaro kanini mugukora imiyoboro ikikijwe n'inkuta zingana na diametre ntoya kandi iringaniye, iruta ubundi buryo buriho.

    Imico isumba iyindi ya S235 J0 izenguruka ibyuma bituma iba nziza kubikorwa bitandukanye.Yaba imishinga yinganda, ubucuruzi cyangwa ibikorwa remezo, iki gicuruzwa cyateguwe kugirango cyuzuze ibisabwa byabakoresha.Imikorere yizewe kandi iramba ituma iba igisubizo cyigiciro cyumushinga uwo ariwo wose usaba kuzenguruka arc tubes.

    X60 Umuyoboro wa SSAW

    Usibye S235 J0 umuyoboro wibyuma, umurongo wibicuruzwa byacu urimoA252 Icyiciro cya 3 Umuyoboro wibyuma.Igicuruzwa cyakozwe hifashishijwe ikoranabuhanga rigezweho ryerekana ubuziranenge kandi bwizewe.Nimbaraga zayo nyinshi kandi zirwanya ruswa, A252 Icyiciro cya 3 cyicyuma nicyiza cyo gusaba.

    Twishimiye gutanga umurongo wuzuye wa spiral submerged arc welded pipe yujuje kandi irenze ibipimo byinganda.Ubwitange bwacu bufite ireme no guhanga udushya byatumye tugira isoko ryizewe mu nganda zikora ibyuma.Twiyemeje kuba indashyikirwa, dukomeje gusunika imipaka yo gukora ibyuma.

    Iyo bigeze kumurongo wizengurutswe arc welded umuyoboro, ibicuruzwa byacu bishyiraho igipimo cyimikorere, kuramba no kwizerwa.S235 J0 Umuyoboro wicyuma na A252 Icyiciro cya 3 Umuyoboro wicyuma ni ingero ebyiri gusa zo kwiyemeza guha abakiriya bacu ibisubizo byiza.Twibanze ku bwiza no guhanga udushya kandi twiyemeje guhaza ibyo abakiriya bacu bakeneye kandi birenze ibyo bategereje.

    Muri make, umuyoboro wicyuma cya S235 J0 hamwe nicyuma cya A252 icyiciro cya 3 nicyuma cya tekinoroji igezweho hamwe nubukorikori buhebuje.Ibicuruzwa bitanga imikorere ntagereranywa, bigatuma bahitamo neza kubikorwa bitandukanye.Yaba ubwubatsi, ibikorwa remezo cyangwa imishinga yinganda, imiyoboro yacu izengurutswe arc gusudira imiyoboro yagenewe gutanga ibisubizo byiza.Wizere ko ubuhanga n'uburambe byacu bizaguha imiyoboro myiza yicyuma ku isoko.
