Igipimo cy'umuyoboro w'icyuma wa Astm A139

Ishusho y'Umuyoboro w'Icyuma wa Astm A139 Isanzwe

Ibisobanuro bigufi:

Waba ukeneye imiyoboro yo kubaka, peteroli na gaze, cyangwa izindi nganda, umuyoboro wacu wa S235 J0 wakozwe kugira ngo uhuze n'ibipimo by'imiyoboro y'icyuma ya ASTM A139 kugira ngo umenye neza ko ari uw'ukuri kandi ugakora neza ndetse no mu bidukikije bigoye cyane.

Ibirango by'ibicuruzwa

Tubagezaho umuyoboro w'icyuma wa S235 J0 - igisubizo gikoreshwa mu buryo butandukanye kugira ngo gihuze n'ibyo inganda zikora muri iki gihe zikeneye. Yakorewe mu ruganda rugezweho ruherereye mu Mujyi wa Cangzhou, mu Ntara ya Hebei, ikigo cyacu cyabaye icya mbere mu gukora ibyuma kuva mu 1993. Iyi sosiyete ifite ubuso bwa metero kare 350.000 kandi ifite umutungo wose wa miliyoni 680 z'ama-ruble. Twishimiye kugira abakozi b'abahanga 680 bitanze mu gutanga ibicuruzwa byiza.

Kimwe mu bintu by’ingenzi biranga umuyoboro w’icyuma wa S235 J0 ni uburyo uhinduka cyane mu bugari n’ubugari bw’inkuta. Ubu buryo bwo guhuza ibintu butuma duhaza ibisabwa bitandukanye mu nganda, cyane cyane mu gukora imiyoboro ifite inkuta nini. Waba ukeneye imiyoboro yo kubaka, peteroli na gaze, cyangwa izindi nganda, umuyoboro wacu wa S235 J0 wakozwe kugira ngo uhuze n’ibikenewe cyane.ASTM A139amahame ngenderwaho y'imiyoboro y'icyuma kugira ngo ihamye ko ari inyangamugayo kandi ikora neza ndetse no mu bidukikije bigoye cyane.

Ubwitange bwacu ku bwiza n'udushya bivuze ko buri gice cy'umuyoboro w'icyuma wa S235 J0 gikorerwa isuzuma rikomeye no kugenzura ubuziranenge, bigatuma ibicuruzwa uhabwa bitanyuranyije n'amahame y'inganda gusa. Kubera ubunararibonye n'ubuhanga bwinshi dufite, twiyemeje guha abakiriya bacu ibisubizo byiza bihuye n'ibyo bakeneye byihariye.

Akamaro k'ibicuruzwa

1. Imwe mu nyungu z'ingenzi z'umuyoboro w'icyuma wa ASTM A139 ni uko woroshye mu bugari n'ubugari bw'inkuta zawo. Uku kwihuza kwemerera abakora imiyoboro gukora imiyoboro y'ingano zitandukanye kugira ngo ihuze n'ibikenewe mu mishinga itandukanye.

2. Ubushobozi bw'umusaruro bw'ikigo nk'icyacu, giherereye i Cangzhou, mu Ntara ya Hebei, byongera ibyiza bya ASTM A139.

3. Uruganda rwacu rwashinzwe mu 1993, rufite ubuso bwa metero kare 350.000, rufite umutungo wose wa miliyoni 680 z'amanyarwanda, kandi rukoresha abakozi b'abahanga 680. Ibi bikorwa remezo binini bidufasha guhaza ibyifuzo bitandukanye by'abakiriya mu gihe tugakomeza kubahiriza amahame yo mu nganda ari hejuru.

Ibura ry'ibicuruzwa

1. Amahame ngenderwaho ya ASTM A139 ashobora kudashyiramo ibisabwa byose byihariye ku bikorwa bimwe na bimwe, bigatuma imikorere ishobora kugabanuka mu bihe bikomeye.

2. Uburyo bwo gukora bushobora kuba bugoye kandi buhenze kurusha andi mahame, ibyo bikaba bishobora kugira ingaruka ku biciro no kuboneka.

Ingaruka

Umuyoboro w'icyuma wa S235 J0 Spiral ufitiye akamaro cyane abakora bitewe n'uko uhuzwa n'uburyo ukoreshwa. Ubushobozi bwo guhindura uburebure n'ubugari bw'inkuta butuma habaho umuyoboro mwiza kandi ufite inkuta nini wujuje ibisabwa mu mishinga yihariye. Ubu buryo bworoshye ntibwongera gusa imikorere myiza mu nganda, ahubwo bunatuma umusaruro wa nyuma ushobora kwihanganira imiterere itandukanye y'ibidukikije n'ibitutu, bigatuma uba ukwiriye gukoreshwa mu buryo butandukanye.

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 z'amanyarwanda, kandi rukoresha abakozi 680 b'abahanga. Ibi bikorwa remezo bikomeye bidufasha gukora imiyoboro y'ibyuma myiza ijyanye n'amahame ya ASTM A139, bigatuma ibicuruzwa byacu byuzuza ibisabwa bikomeye n'abakiriya bacu.

ASTM A139umuyoboro w'icyumaibipimo ngenderwaho bigira ingaruka zikomeye ku ikorwa ry'imiyoboro y'icyuma ya S235 J0, binoza uburyo inganda zikora zihuzwa n'uburyo zikora ndetse n'ubwiza bw'ibicuruzwa. Uko dukomeza guhanga udushya no kwagura ubushobozi bwacu, dukomeje kwiyemeza gutanga ibisubizo by'icyuma cyiza gihuye n'ibyo inganda zikeneye.

Ibibazo Bikunze Kubazwa

Q1: ASTM A139 ni iki?

ASTM A139 ni ibipimo ngenderwaho bigaragaza ibisabwa ku miyoboro y'icyuma ikoreshwa mu bushyuhe bukabije. Iyi miyoboro ikunze gukoreshwa mu gukoresha umuvuduko muto kandi izwiho gukomera no kuramba kwayo. Ibipimo ngenderwaho byemeza ko imiyoboro yujuje imiterere yihariye ya mekanike n'ibinyabutabire, bigatuma ikoreshwa mu buryo butandukanye mu nganda.

Q2: Ni izihe nyungu z'umuyoboro w'icyuma wa S235 J0 wizingiye?

Kimwe mu byiza by'ingenzi by'umuyoboro w'icyuma wa S235 J0 ni uko woroshye mu bugari bwawo n'ubugari bw'inkuta. Uku kwihuza kwemerera abakora umuyoboro gukora umuyoboro w'inkuta nini kandi ukomeye ushobora kwihanganira igitutu gikomeye n'imihangayiko. Ubushobozi bwo guhindura ibi bipimo bituma umuyoboro wa S235 J0 uba amahitamo meza ku mishinga isaba ingano n'imbaraga byihariye.

Ibanjirije iyi: Ibyiza byo gukoresha umushongi wo mu bwoko bwa Helical wo mu rwego rwo hejuru

Ibikurikira: Imiyoboro y'ibyuma byiza cyane iragurishwa
