ASTM A179 (ASME SA179) ni umuyoboro w'icyuma ukozwe mu buryo butagira umugozi ukoreshwa mu byuma bihindura ubushyuhe mu miyoboro, mu byuma bigabanya ubushyuhe, no mu bindi bikoresho bisa nabyo byo kohereza ubushyuhe.
ASTM A179 na ASME SA179 ni ibipimo bibiri bingana rwose. Kugira ngo byorohereze, ASTM A179 ikoreshwa hano hepfo.
ASTM A179 ikwiriye imiyoboro y'icyuma ifite umurambararo w'inyuma wa 1/8″ – 3″ [3.2mm - 76.2mm].
Botop Steelni umucuruzi w'imiyoboro y'icyuma idafite umugozi uturutse mu Bushinwa, iguha amahitamo menshi y'imiyoboro y'icyuma idafite umugozi yo mu rwego rwo hejuru ya ASTM A179/ASME SA179 ikonje kandi idafite umugozi.
Twiyemeje guha abakiriya bacu ibicuruzwa na serivisi byiza cyane kugira ngo imishinga yanyu igende neza. Hitamo Botop Steel, hanyuma uhitemo umufatanyabikorwa wizeye.
Twamaze kuvuga ko A179 ikorwa hakoreshejwe uburyo bwo gukora ibintu bikonje kandi bidafite imitako. Ni izihe nzira zihariye zikoreshwa mu gukora ibintu bikonje kandi bidafite imitako? Reba imbonerahamwe ikurikira y'ibikorwa.
Mu gipimo cya ASTM,A556ikoresha kandi uburyo bwo gukora bukonje kandi butarimo imigozi, ariko by’umwihariko ikoreshwa mu gushyushya amazi mu buryo bw’imiyoboro. Ababishaka bashobora kumenya byinshi.
Nyuma yo gushushanya ubukonje bwa nyuma, imiyoboro y'icyuma ishyushya ku bushyuhe bwa dogere selisiyusi 650 cyangwa irenga.

| ASTM A179 | 0.06-0.18% | 0.27-0.63% | 0.035% ntarengwa | 0.035% ntarengwa |
ASTM A179 ntiyemera kongeramo ibindi bintu mu bigize imiti.
Ubukomere bw'umuyoboro w'icyuma ntibugomba kurenga 72 HRBW (ubukomere bwa Rockwell).

Buri muyoboro ugomba gupimwa umuvuduko wa hydraulic cyangwa, niba umuguzi abitegetse, hashobora gukoreshwa ikizamini cy'amashanyarazi kitangiza.
Umuyoboro w'icyuma ugumana umuvuduko nibura iminota 5 nta gusohoka.
Igitutu cy'ikizamini kibarwa hakoreshejwe formula ikurikira:
Ibipimo bya santimetero - Pound: P = 32000 t/D
Ibice bya SI: P = 220.6t/D
P = igitutu cy'ikizamini cya hydrostatic, psi cyangwa MPa;
t = ubugari bw'urukuta bwagenwe, muri mm cyangwa muri mm;
D = umurambararo wo hanze wagaragajwe, muri. cyangwa mm.
Ibi bikurikira ni ipaki isanzwe ya A179, kandi ipaki yihariye ishobora no gutangwa hakurikijwe ibisabwa n'umushinga.
Umuyoboro wambaye ubusa, irangi ry'umukara (ryahinduwe);
Ingano za santimetero 6 na munsi yazo. Ziri mu mapfundo afite imigozi ibiri y'ipamba, izindi ngano zirekuye;
Impera zombi zifite ibikoresho birinda impera;
Impera isanzwe, impera y'umugongo;
Gushyira ikimenyetso.
