Ibicuruzwa bisobanurwa muburyo butandukanye bwo gukoresha imiyoboro idafite ibyuma (2)

9. Umuyoboro udafite icyuma GB / T8162-1999, nimero yicyuma: 10 #, 20 #, 35 #, 45 # na 16Mn

(Q345), Ibisobanuro: 6-720 * 1-70mm

10. Umuyoboro w'icyuma udafite icyerekezo cyo gutanga amazi GB / T8163-1999, nimero y'ibyuma: 10 #, 20 #, 16Mn (Q345),

Ibisobanuro: 6-720 * 1-70mm

11. Umuvuduko ukabije wumuvuduko wamashanyarazi GB3087-1999, ibyuma No.: 10 #, 20 #, ibisobanuro: 6-720 * 1-70mm

12. Umuyoboro mwinshi utetse GB5310-1995, ibyuma No.: 20G, ibisobanuro: 6-720 * 1-70mm.

“Na” DN ”bisa nkibikoreshwa mu kwerekana diameter, itandukaniro ni:

"" Ikimenyetso cya diameter yumuzingi usanzwe, cyangwa diameter yinyuma yumuyoboro wikubye uburebure bwurukuta, nka: φ25 × 3 biranga diameter yinyuma

Umuyoboro wa 25mm n'ubugari bwa 3mm;“DN”: izina ryizina ryibikoresho nka imiyoboro na valve

Inzira, mubisanzwe yegereye diameter y'imbere.Ni ijambo risanzwe ryashizweho hagamijwe ibikoresho byubaka.

Bisobanura diameter yo hanze, na DN bivuga diameter y'imbere DN: diameter nominal: diameter yo hanze

Noneho imiyoboro- -.nka biri muri santimetero, milimetero ni hafi cyane, byoroshye kwibuka umubare.

Kurugero, umuyoboro wa DN50 ugomba kuba ufite santimetero 2, santimetero 1 = 25.4mm, santimetero 2 ugomba kuba 50mm,

Muri iki gihe, uburebure bwurukuta rwumuyoboro, umuyoboro uzunguruka uri hejuru ya 5mm, ufata 5mm nkurugero,

Diameter yo hanze ya DN50 igomba kuba hafi 60mm.

Q345 umuyoboro wicyuma udafite icyerekezo mubyukuri ni ubwoko bwibikoresho byicyuma.Q bisobanura umusaruro wibi bikoresho,

Nibaruwa yambere ya pinyin, ikurikiwe numubare 345, bivuga agaciro k'umusaruro wibi bikoresho

Kuri cyangwa hafi 345.Kandi igabanya umubare uko ubunini bwibintu bwiyongera.

Icyiciro gisa nuburyo bwo kwita izina icyiciro cya Q235.

Q345A ， Q345B ， Q345C ， Q345D ， Q345E。Iyi ni itandukaniro ryamanota, ihagarariwe na

Ahanini, ni ingaruka zubushyuhe buratandukanye kandi!

Q345A, nta ngaruka;Q345B, ubushyuhe bwa dogere 20;Q345C, ni 0

Impamyabumenyi;Urwego Q345D, ni ingaruka ya dogere 20;Urwego Q345E, ni-40 Impamyabumenyi. Muburyo butandukanye

Ubushyuhe bwingaruka, ingaruka zingaruka nazo ziratandukanye ..

Mu isahani, ni urukurikirane ruto-ruvanze.Ku bikoresho bike-bivanze, ibi bikoresho nibisanzwe.

Q345 umuyoboro wicyuma utagira kashe mubihe byashize witwa: 16Mn umuyoboro wicyuma udafite kashe.

Ibipimo ngenderwaho byo hanze ya Q345 umuyoboro wicyuma ni: GB709, naho igipimo cyimbere ni:

GB / T1591-94
