Nomial diameter na diameter yimbere na hanze yumuyoboro wa stiel

Umuyoboro wa spiralNubwoko bwumuyoboro wicyuma bikozwe muguhindura ibyuma mumiterere yumuyoboro ku mfuruka runaka (ikora inguni) hanyuma irabisunika. Byakoreshejwe cyane muri sisitemu ya pipeline kumavuta, gaze kamere no kwanduza amazi.

Diameter yizina ni diameter yizina ryumuyoboro, agaciro kanini k'ubunini bw'imiyoboro. Kuri spiral steel pie, diameter yizina mubisanzwe yegera, ariko ntabwo angana, imbere imbere cyangwa impamyabumenyi.

Ubusanzwe bigaragazwa na DN wongeyeho umubare, nka DN200, byerekana umuyoboro w'icyuma ufite diameter ya 200 mm.

Diameter isanzwe (DN) intera:
1. Diameter ntoya (DN100 - Dn300):
Dn100 (santimetero 4)
Dn150 (santimetero 6)
Dn200 (santimetero 8)
Dn250 (santimetero 10)
Dn300 (santimetero 12)

2. Diameter Hagati (Dn350 - Dn700):
Dn350 (santimetero 14)
Dn400 (santimetero 16)
Dn450 (santimetero 18)
Dn500 (santimetero 20)
Dn600 (santimetero 24)
Dn700 (santimetero 28)

3. Imiyoboro minini (Dn750 - Dn1200)
Dn750 (santimetero 30)
Dn800 (santimetero 32)
Dn900 (santimetero 36)
Dn1000 (santimetero 40)
Dn1100 (santimetero 44)
Dn1200 (santimetero 48)

4.. Intera nini nini (Dn1300 no hejuru)
Dn1300 (santimetero 52)
Dn1400 (santimetero 56)
Dn1500 (santimetero 60)
Dn1600 (santimetero 64)
Dn1800 (santimetero 72)
Dn2000 (santimetero 80)
Dn2200 (santimetero 88)
Dn2400 (santimetero 96)
Dn2600 (104 ya santimetero)
Dn2800 (santimetero 112)
Dn3000 (santimetero 120)

Diameter yo hanze (od): od ni diameter yubuso bwo hanze bwumuyoboro wa spiral. Umuyoboro wumuyoboro wa spiral ni ubunini bwukuri bwo hanze yumuyoboro. Od irashobora kuboneka kubipimo nyabyo, mubisanzwe muri milimetero (mm).
Imiyoboro y'imbere (ID): Indangamuntu ni diameter yubuso bwimbere bwumuyoboro wa spiral. Indangamuntu nubunini bwukuri bwimbere mumuyoboro. Indangamuntu isanzwe ibarwa mugukuramo kabiri urukuta rwurukuta ruva muri od muri milimetero (mm) id = od-2 x umubyimba

Porogaramu

Imiyoboro ya spiral ibyuma hamwe na diameter itandukanye ifite porogaramu zitandukanye mumirima itandukanye:
1. Diameter ntoUmuyoboro wa Ssaw.
2. DiameterUmuyoboro wa Ssaw. 3. Umuyoboro munini wa diameter
3.Diameter nini ssaw.
4. Ultra-diameterSsaw carbone steel pie.

Diameter yizina hamwe nibindi bisobanuro byimiyoboro yicyuma bikunze gukorwa hakurikijwe ibipimo nibisobanuro bijyanye:
1.
2. Ibipimo byigihugu: GB / T 9711: Bikoreshwa kumuyoboro wibyuma kugirango ushyire mu nganda za peteroli na gaze, ugaragaza ibisabwa bya tekiniki byimiyoboro ya spiral. GB / T 3091: Bikoreshwa mugusunika ibyuma bisuye byamazi yo gutwara ibipimo, byerekana ibipimo nibisabwa bya tekiniki byumuyoboro wa spiral.
