    Astm A139 Umuyoboro wicyuma

    Astm A139 Umuyoboro wibyuma bisanzwe Ishusho
    • Astm A139 Umuyoboro wicyuma

    Ibisobanuro bigufi:

    Waba ukeneye umuyoboro wubwubatsi, peteroli na gaze, cyangwa izindi nganda zikoreshwa mu nganda, umuyoboro wa S235 J0 wakozwe kugirango wuzuze amahame akomeye ya ASTM A139 yicyuma kugirango wizere kandi ukore ndetse no mubidukikije bisabwa cyane.


    Ibicuruzwa birambuye

    Ibicuruzwa

    Kumenyekanisha umuyoboro wibyuma bya S235 J0 - igisubizo kinyuranye cyagenewe guhuza ibyifuzo bitandukanye byinganda zigezweho. Isosiyete yacu ikorerwa mu ruganda rugezweho ruherereye mu mujyi wa Cangzhou, mu Ntara ya Hebei, isosiyete yacu yabaye umuyobozi mu bijyanye no gukora ibyuma kuva mu 1993. Iyi sosiyete ifite ubuso bwa metero kare 350.000 kandi ifite umutungo wa miliyoni 680. Twishimiye kuba dufite abakozi bitangiye abakozi 680 babigize umwuga bitangiye gutanga ibicuruzwa byiza.

    Kimwe mu bintu byingenzi biranga S235 J0 umuyoboro wibyuma ni uburyo bworoshye bwo guhinduka bwa diameter hamwe nuburinganire bwurukuta. Uku guhuza n'imihindagurikire y'ikirere bidushoboza kuzuza ibisabwa bitandukanye byo gukora, cyane cyane mu gukora imiyoboro yo mu rwego rwo hejuru ikikijwe n'inkuta. Waba ukeneye umuyoboro wubwubatsi, peteroli na gaze, cyangwa nibindi bikorwa byinganda, umuyoboro wa S235 J0 wakozwe kugirango uhuze bikomeyeASTM A139ibyuma byicyuma kugirango wizere kwizerwa no gukora mubidukikije bisabwa cyane.

    Twiyemeje ubuziranenge no guhanga udushya bivuze ko buri gice cyumuyoboro wa S235 J0 kizunguruka kigeragezwa cyane kandi kigenzura uburyo bwiza, kwemeza ko ibicuruzwa wakiriye bitujuje gusa ahubwo birenze ibipimo byinganda. Hamwe n'uburambe n'ubunararibonye dufite, twiyemeje guha abakiriya bacu ibisubizo byiza byujuje ibyifuzo byabo.

    Ibyiza byibicuruzwa

    1. Kimwe mu byiza byingenzi bya ASTM A139 umuyoboro wibyuma nuburyo bworoshye bwa diameter hamwe nuburinganire bwurukuta. Uku guhuza n'imihindagurikire y'ikirere bituma abayikora bakora imiyoboro mu bunini butandukanye kugira ngo bashobore gukora imishinga itandukanye.

    2. Ubushobozi bwo kubyaza umusaruro isosiyete nkiyacu, iherereye i Cangzhou, Intara ya Hebei, byongera ibyiza bya ASTM A139.

    3. Yashinzwe mu 1993, uruganda rwacu rufite ubuso bwa metero kare 350.000, rufite umutungo wa miliyoni 680, kandi rukoresha abakozi 680 bafite ubumenyi. Ibikorwa remezo binini bidushoboza guhaza ibyifuzo byinshi byabakiriya mugihe dukomeza ibipimo ngenderwaho byo hejuru.

    Ibura ry'ibicuruzwa

    1. Ibipimo bya ASTM A139 ntibishobora gukurikiza ibisabwa byihariye kubisabwa bimwe, bivamo imikorere mike mugihe gikabije.

    2.Ibikorwa byo kubyaza umusaruro birashobora kuba bigoye kandi bihenze kuruta ibindi bipimo, bishobora kugira ingaruka kubiciro no kuboneka.

    Ingaruka

    S235 J0 Umuyoboro wibyuma bifasha cyane cyane ababikora kubera guhuza n'imiterere. Ubushobozi bwo gutandukanya diametero nubunini bwurukuta butuma habaho umusaruro wa premium, umuyoboro wuzuye urukuta rwujuje ibyangombwa bisabwa byumushinga. Ihinduka ntabwo ryongera imikorere yinganda gusa, ahubwo inemeza ko ibicuruzwa byanyuma bishobora guhangana n’ibidukikije bitandukanye n’ibidukikije, bigatuma bikwiranye n’ibikorwa byinshi.

    Uruganda rwacu ruherereye i Cangzhou, mu Ntara ya Hebei, kandi rwagize uruhare runini mu nganda z’ibyuma kuva rwashingwa mu 1993. Uruganda rwacu rufite ubuso bwa metero kare 350.000, rufite umutungo wa miliyoni 680, kandi rukoresha abakozi 680 babishoboye. Ibikorwa remezo bikomeye bidushoboza gukora imiyoboro yicyuma yujuje ubuziranenge yujuje ubuziranenge bwa ASTM A139, ikemeza ko ibicuruzwa byacu byujuje ibyifuzo byabakiriya bacu.

    ASTM A139umuyoboro w'icyumaigipimo kigira ingaruka zikomeye ku musaruro w’icyuma cya S235 J0 kizunguruka, kunezeza inganda n’ubwiza bw’ibicuruzwa. Mugihe dukomeje guhanga udushya no kwagura ubushobozi bwacu, dukomeza kwiyemeza gutanga ibisubizo byicyuma bisumba ibindi byujuje ibyifuzo byinganda.

    Ibibazo

    Q1: ASTM A139 ni iki?

    ASTM A139 nigisobanuro gisanzwe cyerekana ibisabwa kugirango umuyoboro wibyuma-birwanya amashanyarazi. Iyi miyoboro isanzwe ikoreshwa mugukoresha ingufu nkeya kandi izwiho imbaraga nigihe kirekire. Igipimo cyemeza ko imiyoboro ihura nubukanishi bwihariye hamwe nubumara bwimiti, bigatuma bikoreshwa mubikorwa bitandukanye byinganda.

    Q2: Ni izihe nyungu za S235 J0 umuyoboro wibyuma?

    Imwe mu nyungu zingenzi za S235 J0 umuyoboro wicyuma ni uburyo bworoshye bwa diameter hamwe nuburinganire bwurukuta. Uku guhuza n'imihindagurikire y'ikirere bituma abayikora bakora imiyoboro yo mu rwego rwo hejuru, ikikijwe n'inkuta zishobora kwihanganira imikazo ikomeye. Ubushobozi bwo guhitamo ibi bisobanuro butuma S235 J0 umuyoboro uhitamo neza imishinga isaba ubunini n'imbaraga byihariye.
