Ubushinwa Bwiza Q235C Q235B 16Mn Umuyoboro wa karuboni Weld / umuyoboro
Incamake
Isosiyete ishyigikiye filozofiya ya "Ba uwambere mu gukemura imiyoboro", tuzakomeza gukorera abakiriya babanjirije n'abashya kuva mu gihugu no mu mahanga cyane. Ku byuma bya karubone byasuditswe cyangwa bidafite icyerekezo gikurikiza ASTM A53, dufite uburambe bwimyaka irenga 30 yo kugura no kugurisha, bishobora kwemeza ko dufite ubushobozi bwo kwemeza ko buri miyoboro ifite ubuziranenge.
Kubijyanye n'umuyoboro udafite ikidodo, hariho umuyoboro wimpimbano udahari, umutungo wubukanishi uri munsi yumuyoboro udafite kashe, kuko bikozwe mumiyoboro ya ERW, nyuma yuburyo butunganijwe, ni umurongo wo gusudira wahindutse hafi itagaragara. Uyu muyoboro mwiza ntushobora kwihanganira umuvuduko mwinshi, nimbaraga zikaze, guhangayika imbere byose ntibishobora kuzuza ibisabwa kubyerekeranye numuyoboro udafite kashe. Ongera uvange iyi miyoboro ibiri yubwoko, nyamuneka menya ko umuyoboro wa ERW byose bikozwe mumirongo yicyuma, bityo rero ifite uburebure bwurukuta rumwe; Umuyoboro udafite ubudodo bukozwe mu ruziga ruzengurutse, rusobekeranye rwagati rwagati kugira ngo rukore imiyoboro, bityo uburebure bwurukuta ntabwo ari bumwe. Kandi umurongo wo gusudira wumuyoboro udahimbano uracyahari, niba ugenzura imiyoboro imbere witonze, urashobora kuyibona.
Irakoreshwa Cyane kubice byingufu nigitutu, no mubikorwa rusange ibyuka, amazi, gaze numuyoboro wikirere.
