    ASTM A139 Igipimo cyicyuma

    ASTM A139 Icyuma gisanzwe gisanzwe
    • ASTM A139 Igipimo cyicyuma

    Ibisobanuro bigufi:

    Waba ukeneye umuyoboro wo kubaka, peteroli na gaze, cyangwa izindi porogaramu zinganda, umuyoboro wa S235 wamenetse kugirango uhuze astm a1m a1m a1m a139 mubidukikije.


    Ibisobanuro birambuye

    Ibicuruzwa

    Kumenyekanisha S235 j0 spiral spiral ibyuma - Igisubizo gisobanutse kugirango uhuze ninganda zigezweho. Yakozwe mu ruganda rukora mu mujyi wa Leta uherereye mu mujyi wa Hebei, Isosiyete yacu yabaye umuyobozi mu miterere y'ibyuma kuva 1993. Isosiyete ikubiyemo akarere ka metero kare 350.000 kandi ifite imitungo yose ya miliyoni 680 . Twishimiye kugira abakozi bitanze bafite abanyamwuga 680 b'abahanga bahari batanga ibicuruzwa byiza.

    Kimwe mu bintu by'ingenzi bya S235 j0 j0 umuyoboro w'icyuma ni uguhinduka cyane muri diameter hamwe nimyumbati. Ubu buryo bwo guhuza ibishoboka bidushoboza kuzuza ibisabwa bitandukanye bisabwa, cyane cyane mugukora imiyoboro yo murwego rwohejuru. Waba ukeneye umuyoboro wo kubaka, peteroli na gaze, cyangwa izindi porogaramu zinganda, S235 j0 ya pream yamejwe guhuraASTM A139Amashanyarazi yubucuruzi kugirango yizere ko yizewe n'imikorere ndetse n'ibidukikije bisabwa.

    Ubwitange bwacu bwo ubuziranenge no guhanga udushya bisobanura buri gice cya S235 j0 spiral spiral stal spiral yipimisha ingufu no kugenzura ubuziranenge, iremeza ibicuruzwa utabona gusa ahubwo birenga ibipimo ngenderwaho. Hamwe nubunararibonye bwacu nubuhanga bwacu, twiyemeje guha abakiriya bacu ibisubizo byiza bikwiranye no kubahiriza ibyo bakeneye.

    Inyungu y'ibicuruzwa

    1. Kimwe mubyiza nyamukuru bya ASTM A139 umuyoboro w'icyuma ni uguhinduka muri diameter hamwe nintoki zidasanzwe. Ubu buryo bwo guhuza ibipimo bituma abakora kubyara imiyoboro muburyo butandukanye bwo guhura nibisabwa bitandukanye.

    2. Ubushobozi bwo gukora nk'ibyacu, giherereye i Cancemzhou, Intara ya Hebei, kuzamura ibyiza bya ASTM A139.

    3. Uruganda rwacu rwashinzwe, uruganda rwacu rukubiyemo ubuso bwa metero kare 350.000, ufite umutungo wose w'intama miliyoni 680, kandi ukoresha abakozi 680 b'abahanga. Ibikorwa remezo byinshi bidushoboza guhura numukiriya muburyo butandukanye mugihe ukomeje ibipimo ngenderwaho.

    Ibicuruzwa Kubura

    1. ASTM A139 Standard ntishobora gukubiyemo ibisabwa byose kubisabwa, bikaviramo imikorere ishobora kugarukira mubihe bikabije.

    2. Inzira yumusaruro irashobora kuba igoye kandi ihenze kurenza izindi mahame, ishobora kugira ingaruka kubiciro no kuboneka.

    Ingaruka

    S235 j0 umuyoboro w'icyuma ufitiye akamaro cyane ababikora kubera guhuza n'imihindagurikire. Ubushobozi bwo gutunganya imiyoboro hamwe nurukuta rwemerera gukora premium, umuyoboro ukikijwe cyane uhuye nibisabwa byimishinga runaka. Ihinduka ridahinduka ryongeye gukora neza, ariko kandi ryemeza ko ibicuruzwa byanyuma bishobora kwihanganira ibihe bitandukanye nibidukikije hamwe nigitutu, bigatuma bikwiranye nuburyo butandukanye.

    Uruganda rwacu ruherereye muri Cangzhou, Intara ya Hebei, kandi rwabaye umukinnyi w'ingenzi mu nganda z'ibyuma kuva hashyirwaho metero kare 350.000, ifite umutungo wose w'intama miliyoni 680, kandi ukoreshe abantu 680 abakozi. Ibikorwa remezo bikomeye bidushoboza kubyara imiyoboro myiza yicyuma byujuje ibipimo bya ASTM A139, byemeza ko ibicuruzwa byacu byujuje ibyangombwa byabakiriya bacu.

    ASTM A139umuyoboro w'icyumaIbipimo bigira ingaruka zikomeye kumusaruro wa S235 j0 spiral steel steel, kuzamura imikoreshereze yo guhuza n'imiterere. Mugihe dukomeje guhanga udushya no kwagura ubushobozi bwacu, dukomeza kwiyemeza gutanga ibisubizo byicyuma bikabije byujuje ibikenewe byinganda zikenewe.

    Ibibazo

    Q1: ASTM A139 ni iki?

    ASTM A139 nicyo kisobanuro gisanzwe cyerekana ibisabwa kugirango ugaragaze amabuye yamashanyarazi. Iyi miyoboro isanzwe ikoreshwa muburyo bwimiturire mike kandi izwiho imbaraga nimbaro. Ibipimo byemeza ko imiyoboro yujuje imiterere yihariye hamwe nibigize imiti, bigatuma bikwiranye nuburyo butandukanye bwinganda.

    Q2: Ni izihe nyungu za S235 j0 plipe ibyuma?

    Imwe mu nyungu nyamukuru ya S235 j0 umuyoboro w'icyuma ni uguhinduka muri diameter hamwe nimyumbati. Iyi miterere yemerera abakora gukora umuyoboro wo hejuru, urusaku rwinshi rushobora kwihanganira imikazo nini. Ubushobozi bwo guhitamo ibi byihariye bituma S235 j0 j0 yahisemo guhitamo imishinga isaba ubunini n'imbaraga zihariye.
