Umurambararo n'umurambararo w'imbere n'inyuma by'umuyoboro w'icyuma gizunguruka

Umuyoboro w'icyuma uzungurukani ubwoko bw'umuyoboro w'icyuma ukozwe binyuze mu kuzingira agace k'icyuma mu ishusho y'umuyoboro ku nguni runaka y'uruziga (inguni yo gukora) hanyuma ukawusudira. Ukoreshwa cyane mu miyoboro yo kohereza peteroli, gaze karemano n'amazi.

Umurambararo w'umuyoboro ni umurambararo w'umuyoboro, agaciro k'umurambararo w'umuyoboro. Ku muyoboro w'icyuma uzunguruka, umurambararo w'umuyoboro usanzwe wegereye, ariko ntungana n'umurambararo nyawo w'imbere cyangwa inyuma.

Ubusanzwe igaragazwa na DN hamwe n'umubare, nka DN200, igaragaza umuyoboro w'icyuma ufite umurambararo wa mm 200.

Uruhererekane rw'umurambararo rusange (DN):
1. Ingano nto y'umurambararo (DN100 - DN300):
DN100 (inchi 4)
DN150 (inchi 6)
DN200 (inchi 8)
DN250 (inchi 10)
DN300 (inchi 12)

2. Ingano y'umurambararo uringaniye (DN350 - DN700):
DN350 (inchi 14)
DN400 (inchi 16)
DN450 (inchi 18)
DN500 (inchi 20)
DN600 (inchi 24)
DN700 (inchi 28)

3. Ingano nini y'umurambararo (DN750 - DN1200)
DN750 (santimetero 30)
DN800 (inchi 32)
DN900 (inchi 36)
DN1000 (inchi 40)
DN1100 (inchi 44)
DN1200 (inchi 48)

4. Ingano nini cyane y'umurambararo (DN1300 no hejuru yayo)
DN1300 (inchi 52)
DN1400 (inchi 56)
DN1500 (inchi 60)
DN1600 (inchi 64)
DN1800 (inchi 72)
DN2000 (inchi 80)
DN2200 (inchi 88)
DN2400 (inchi 96)
DN2600 (inchi 104)
DN2800 (inchi 112)
DN3000 (inchi 120)

Umurambararo wo hanze (OD): OD ni umurambararo w'ubuso bw'inyuma bw'umuyoboro w'icyuma uzunguruka. OD y'umuyoboro w'icyuma uzunguruka ni ingano nyayo y'inyuma y'umuyoboro. OD ishobora kuboneka hakoreshejwe uburyo nyabwo bwo gupima, ubusanzwe muri milimetero (mm).
Ingano y'imbere (ID): ID ni umurambararo w'ubuso bw'imbere bw'umuyoboro w'icyuma uzunguruka. ID ni ingano nyayo y'imbere y'umuyoboro. ID ikunze kubarwa hakurwamo kabiri ubunini bw'urukuta kuri OD muri milimetero (mm) ID = OD-2 x Ubunini bw'urukuta

Ahantu ho gusaba

Imiyoboro y'icyuma ikoze mu buryo bw'uruziga ifite uburebure butandukanye ifite akamaro gatandukanye mu nzego zitandukanye:
1. umurambararo mutoUmuyoboro w'icyuma cya Ssaw(DN100 - DN300): ikoreshwa cyane mu buhanga bw'umujyi ku miyoboro y'amazi, imiyoboro y'amazi, imiyoboro ya gazi, n'ibindi.
2. umurambararo uringaniyeUmuyoboro wa Ssaw(DN350 - DN700): ikoreshwa cyane mu miyoboro ya peteroli, gaze karemano n'imiyoboro y'amazi y'inganda. 3. umuyoboro munini w'icyuma gikoze mu buryo bwa spiral (DN100 - DN300): ikoreshwa cyane mu miyoboro y'amazi y'ubuhanga mu by'umujyi, imiyoboro y'amazi, imiyoboro ya gaze, n'ibindi.
3.Umuyoboro munini wa Ssaw ufite uburebure bunini(DN750 - DN1200): ikoreshwa mu mishinga yo kohereza amazi mu ntera ndende, imiyoboro ya peteroli, imishinga minini y’inganda, nko gutwara abantu n’ibintu mu buryo buciriritse.
4. umurambararo munini cyaneUmuyoboro w'icyuma cya karuboni cya Ssaw(DN1300 no hejuru yayo): ikoreshwa cyane cyane mu mishinga y'imiyoboro y'amazi, peteroli na gazi ikorerwa mu turere twinshi, imiyoboro y'amazi yo munsi y'amazi n'indi mishinga minini y'ibikorwa remezo.

Ubugari bw'umurambararo n'ibindi bipimo by'umuyoboro w'icyuma uzunguruka bikunze gukorwa hakurikijwe ibipimo n'ibipimo bireba:
1. Ibipimo ngenderwaho mpuzamahanga: API 5L: ikoreshwa ku muyoboro w'icyuma utwara imiyoboro, igaragaza ingano n'ibikenewe ku muyoboro w'icyuma uzenguruka ASTM A252: ikoreshwa ku muyoboro w'icyuma uzubakwa, igaragaza ingano n'ibisabwa mu gukora umuyoboro w'icyuma uzenguruka.
2. Igipimo ngenderwaho cy’igihugu: GB/T 9711: gikoreshwa ku muyoboro w’icyuma mu gutwara ibikomoka kuri peteroli na gaze, kigaragaza ibisabwa mu bya tekiniki ku muyoboro w’icyuma uzunguruka. gb/t 3091: gikoreshwa ku muyoboro w’icyuma uzunguruka mu gutwara amazi make, kigaragaza ingano n’ibisabwa mu bya tekiniki ku muyoboro w’icyuma uzunguruka.
