Hitamo umuyoboro wibyuma kandi witondere ibipimo bishya!

GB / T.Mugihe kimwe, verisiyo yumwimerere ya GB / T 3091-2008 ntabwo yemewe kumugaragaro!

Gusobanura ingingo zingenzi zurwego rushya rwigihugu:

1. Uburemere bwa Galvanised - “Umurongo wo hasi”

Mubipimo bishya byigihugu, kuri zinc layer yuburemere bwibipimo byicyuma cya galvanised kunshuro yambere shyira imbere "ibisabwa kumurongo wo hasi"!Mubisanzwe: muri verisiyo ishaje yuburyo busanzwe "amagambo yumvikanyweho" hashingiwe ku kongera "imiyoboro y'icyuma imbere n'inyuma yo hejuru ya galvanised layer unit agace uburemere bwose ntibugomba kuba munsi ya 300g / m²" ibisabwa bisanzwe.

Nkigisubizo, impuzandengo yubuzima bwicyuma cyongerwa byibuze 30% !!

2. Impera y'umuyoboro

Imiyoboro y'ibyuma ifite diameter yo hanze itarenza 114.3mm (santimetero 4 cyangwa munsi) igomba kuba iringaniye (idafite burrs kumpera).

3. Gusana gusudira inenge

Nyuma yo kuvugurura ibipimo bishya, gusana inenge byahinduwe kuri: umuyonga ugororotse wamashanyarazi weld wicyuma ufite diameter yo hanze munsi ya 219.1mm ntabwo byemewe gusana gusudira.

Kugereranya: GB / T3091-2008 iteganya ko "umuyoboro w'icyuma ufite diameter yo hanze itarenza 114.3mm utemerewe gusana gusudira, umuyoboro w'icyuma ufite diameter yo hanze utari munsi ya 114.3mm, urashobora gusana inenge ku cyuma fatizo no gusudira."

4. Ubunini bw'urukuta

Igipimo gishya giteganya agaciro ntarengwa k'uburebure bw'urukuta rw'izina ry'umuyoboro w'icyuma, ni ukuvuga, Imbonerahamwe ya 1 “Diameter ya Nominal, diameter yo hanze, Uburebure bw'Urukuta rwa Nominal hamwe no kutuzenguruka kw'umuyoboro w'icyuma ufite diameter yo hanze itarenza 219.1mm” wongeyeho, utanga a ishingiro ritaziguye mugushushanya no gutoranya ibikoresho byubushakashatsi.

Ip Umuyoboro wibyuma ufite uburebure bwurukuta ruri munsi ya ** ntoya ntabwo byemewe gukora GB / T3091-2015 !!

5. Ikimenyetso cy'umuyoboro w'icyuma

Igipimo gishya kigira kiti: “Ikimenyetso cy'imiyoboro y'ibyuma kigomba kuba gikubiyemo nibura ibi bikurikira: izina ry'umukoresha cyangwa ikirango, inomero y'ibicuruzwa, inomero y'ibicuruzwa, nimero y'ibicuruzwa na nimero iranga ibimenyetso.”

Ikimenyetso cyicyuma kigizwe nibirango byibicuruzwa hamwe na kode yumubiri.Niba hari amakuru yavuzwe haruguru yabuze, birabujijwe.
