Gusobanura neza ingano y'umuyoboro w'icyuma bigomba kuba birimo ibipimo byinshi by'ingenzi:
Diameter yo hanze (OD)
Umurambararo wo hanze w'umuyoboro w'icyuma, ubusanzwe ugaragazwa nk'umurambararo w'amazina (DN) cyangwa ingano y'umuyoboro w'amazina (NPS).
Ingano y'umuyoboro w'amazina (NPS) ugereranije n'umurambararo w'amazina (DN)
NPS ni ingano y’inyuguti ishingiye kuri santimetero, mu gihe DN ari umurambararo w’inyuguti muri milimetero. Isano yo guhindura ni iyoroshye: agaciro ka DN kangana n’agaciro ka NPS kakubye 25.4 (mm/inch) kugira ngo harebwe igisubizo.
Mu by’ukuri, isano iri hagati y’ibipimo bya NPS na DN ishingiye cyane ku mbonerahamwe z’ibipimo byashyizweho.
Ubunini bw'urukuta (WT)
Ubunini bw'urukuta rw'umuyoboro. Ku muyoboro usanzwe, ubunini bw'urukuta bukunze kujyana n'Imbonerahamwe y'umuyoboro, urugero: Imbonerahamwe ya 40 cyangwa Imbonerahamwe ya 80, aho agaciro kanini kagaragaza inkuta nini.
Uburebure
Uburebure bw'umuyoboro w'icyuma, bushobora gukosorwa cyangwa bugakorwa mu buryo butunguranye, bitewe n'umusaruro n'ibisabwa mu ikoreshwa. Uburebure busanzwe ni metero 6 na metero 12.
Ibikoresho
Ibipimo ngenderwaho n'amanota y'ibikoresho by'imiyoboro y'icyuma, nka ASTM A106 Grade B, API 5L Grade B, n'ibindi. Aya mabwiriza agaragaza imiterere y'imiti n'imiterere y'umubiri w'umuyoboro.
Amahame
Ibipimo ngenderwaho by'imiyoboro ya karuboni n'icyuma kidashonga cyane cyane bikurikira ASME B36.10M (icyuma kidashonga na alloy) na B36.19M (umuyoboro utagira icyuma kidashonga).
Ameza y'ingano y'imiyoboro n'ameza y'uburemere (WGT)
tanga uburyo busanzwe bwo gusobanura ubugari bw'inkuta z'imiyoboro hakurikijwe Ingengabihe zitandukanye, ndetse no gushyira mu byiciro uburemere nka STD, XS, XXS, n'izindi.
Ubugari bw'urukuta rw'umuyoboro bugira ingaruka zitaziguye ku bipimo by'imbere n'uburemere bw'umuyoboro. Ubugari bw'urukuta ni ingenzi kuko bugena ingano y'igitutu cy'imbere umuyoboro ushobora kwihanganira.
Nimero y'ingengabihe
Uburyo bwo kwerekana ubugari bw'urukuta rw'umuyoboro, bukunze kuba nk'umugereka wa 40 na 80, bwerekeza ku bugari bw'urukuta busanzwe kandi bushyigikiwe bw'umuyoboro ku murambararo w'inyuma watanzwe.
Ibarwa ry’umubare w’ingengabihe ni iri rikurikira:
Kubera ubushobozi bwayo bwo kwihanganira igitutu gisanzwe, imiyoboro y'icyuma ya Schedule 40 na Schedule 80 ikunze gukenerwa mu nganda zitandukanye. Kubera ko iyi miyoboro yagenewe kwihanganira igitutu kinini, ikunze gukenerwa ku bwinshi kugira ngo ihuze n'ibyo inganda zitandukanye zikeneye.

Bityo rero, urugero rwuzuye rw'ingano y'umuyoboro w'icyuma rushobora kuba "NPS santimetero 6, Gahunda ya 40, ASTM A106 Grade B, Uburebure bwa metero 6". Ibi bigaragaza umuyoboro w'icyuma ufite umurambararo wa santimetero 6, Gahunda ya 40, ikozwe hakurikijwe ibipimo bya ASTM A106 Grade B, kandi ifite uburebure bwa metero 6.
