Diameter ya nominal na diameter y'imbere ninyuma yumuringa wicyuma

Umuyoboro w'icyumani ubwoko bwicyuma gikozwe mukuzunguza umurongo wicyuma muburyo bwa pipe kumurongo runaka uzenguruka (gukora inguni) hanyuma ukabisudira. Ikoreshwa cyane muri sisitemu y'imiyoboro ya peteroli, gaze gasanzwe no kohereza amazi.

Diameter ya nominal ni diameter nominal ya pipe, agaciro ka nomero yubunini bwa pipe. Ku muyoboro w'icyuma kizunguruka, diameter nominal isanzwe yegereye, ariko ntabwo ihwanye na, imbere imbere cyangwa hanze ya diameter.

Ubusanzwe bigaragazwa na DN wongeyeho umubare, nka DN200, yerekana umuyoboro wibyuma ufite diameter ya nomero 200.

Urutonde rusanzwe rwa diameter (DN):
1. Urutonde ruto rwa diameter (DN100 - DN300):
DN100 (santimetero 4)
DN150 (santimetero 6)
DN200 (santimetero 8)
DN250 (santimetero 10)
DN300 (santimetero 12)

2. Urwego rwa diameter rwagati (DN350 - DN700):
DN350 (santimetero 14)
DN400 (santimetero 16)
DN450 (santimetero 18)
DN500 (santimetero 20)
DN600 (santimetero 24)
DN700 (santimetero 28)

3. Urwego runini rwa Diameter (DN750 - DN1200)
DN750 (santimetero 30)
DN800 (santimetero 32)
DN900 (santimetero 36)
DN1000 (santimetero 40)
DN1100 (santimetero 44)
DN1200 (santimetero 48)

4. Urwego runini rwa diameter (DN1300 no hejuru)
DN1300 (santimetero 52)
DN1400 (santimetero 56)
DN1500 (santimetero 60)
DN1600 (santimetero 64)

DN2000 (santimetero 80)
DN2200 (santimetero 88)
DN2400 (santimetero 96)
DN2600 (santimetero 104)
DN2800 (santimetero 112)
DN3000 (santimetero 120)

Diameter yo hanze (OD): OD ni diameter yubuso bwinyuma bwumuyoboro wicyuma. OD y'umuyoboro w'icyuma ni ubunini nyabwo bwo hanze y'umuyoboro. OD irashobora kuboneka mubipimo bifatika, mubisanzwe muri milimetero (mm).
Imbere Imbere (ID): ID ni diameter yubuso bwimbere bwumuyoboro wicyuma. Indangamuntu nubunini nyabwo imbere bwumuyoboro. Indangamuntu isanzwe ibarwa mugukuramo kabiri uburebure bwurukuta kuva OD muri milimetero (mm) ID = OD-2 x Ubukuta bwurukuta

Umwanya wo gusaba

Imiyoboro ya spiral ifite diametre zitandukanye zifite porogaramu zitandukanye mubice bitandukanye:
1. Diameter ntoSsaw Umuyoboro.
2Umuyoboro wa Ssaw(DN350 - DN700): ikoreshwa cyane mu mavuta, umuyoboro wa gazi karemano n'umuyoboro w'amazi mu nganda. 3. Umuyoboro munini wa diameter nini ya spiral (DN100 - DN300): ukunze gukoreshwa mumuyoboro wogutanga amazi ya komini, umuyoboro wamazi, umuyoboro wa gazi, nibindi.
3.Umuyoboro munini wa Diameter Ssaw(DN750 - DN1200): ikoreshwa mumishinga yohereza amazi maremare, imiyoboro ya peteroli, imishinga minini yinganda, nko gutwara abantu n'ibintu.
4. diameter nini cyaneSsaw Umuyoboro wa Carbone.

Diameter yizina nibindi bisobanuro byumuyoboro wibyuma bizunguruka bikurikije ibipimo nibisobanuro:
1.
2. Igipimo cyigihugu: GB / T 9711: gikoreshwa kumuyoboro wibyuma byo gutwara inganda za peteroli na gaze, byerekana ibisabwa bya tekiniki yumuyoboro wicyuma. gb / t 3091: ikoreshwa kumuyoboro wicyuma usudira kugirango utwarwe n'umuvuduko ukabije wamazi, ugaragaza ibipimo nibisabwa tekiniki byumuyoboro wicyuma.
