Imiyoboro ikonje, EN10219 S235JRH, S235J0H, S355JRH, S355J0H

Ibisobanuro bigufi:

Iki gice cy'iyi Standard y'Uburayi kigaragaza uburyo tekiniki ikoreshwa mu gutanga ibikoresho ku bice by'imiterere bikonje, bifite ubukonje, impande z'imiterere y'uruziga, kare cyangwa uruziga rw'urukiramende, kandi gikoreshwa ku bice by'imiterere bifite ubukonje bidakoresheje ubushyuhe.

Cangzhou Spiral Steel Pipes Group Co., Ltd itanga igice cy'imiyoboro y'icyuma ifite imiterere izengurutse kugira ngo ikoreshwe mu nyubako.

a. Uburyo bwo gukuraho ogisijeni mu mubiri bugenwa ku buryo bukurikira: FF: Icyuma cyapfuye cyose kirimo ibintu bihuza azote mu rugero ruhagije kugira ngo gifatanye azote ihari (urugero: 0.020% by'Al yose cyangwa 0.015% by'Al ishongesha). b. Agaciro ntarengwa ka azote ntigakurikizwa iyo imiterere y’imiti igaragaza ko Al yose hamwe na 0.020% hamwe na Al/N ya 2:1, cyangwa niba hari ibindi bintu bihagije bihambira kuri N. Ibintu bihambira kuri N bigomba kwandikwa mu nyandiko y’igenzura.

Ikizamini cy'amazi

Buri burebure bw'umuyoboro bugomba kugeragezwa n'uruganda ku gitutu cya hydrostatic kizatera mu rukuta rw'umuyoboro igitutu kitari munsi ya 60% by'imbaraga z'umusaruro ntarengwa wagenwe ku bushyuhe bw'icyumba. Igitutu kigomba kugenwa n'ikigereranyo gikurikira:
P=2St/D

Impinduka zemewe mu buremere n'ingano

Uburebure bwa buri muyoboro bugomba gupimwa ukwabwo kandi uburemere bwabwo ntibugomba gutandukana kurenza 10% hejuru cyangwa 5.5% munsi y'uburemere bwabwo, bubarwa hakoreshejwe uburebure bwabwo n'uburemere bwabwo kuri buri gice cy'uburebure.
Umurambararo wo hanze ntugomba gutandukana kurenza ± 1% ugereranije n'umurambararo wo hanze wagenwe
Ubunini bw'urukuta aho ari ho hose ntibugomba kurenza 12.5% munsi y'ubunini bw'urukuta bwagenwe

Ibanjirije iyi: Imiyoboro y'icyuma ishongeshejwe mu buryo bw'umwuka ASTM A252 Icyiciro cya 1 2 3
