Ubwino wapamwamba China Sch40 A53 A106 API 5L Wopanda Msoko ndi Wowotcherera Chitoliro Chachitsulo cha Carbon
Mwachidule
"Kuwona mtima, Kupanga Zinthu, Kukhwima, ndi Kuchita Bwino" kungakhale lingaliro losalekeza la bungwe lathu, kwa nthawi yayitali mpaka kuyanjananso, Pakalipano, dzina lolimba lili ndi zitsulo za carbon ndi Cr Mo Alloy Steel ndipo adapeza mbiri yabwino komanso magawo akuluakulu. pamsika wapanyumba ndi kunja.
Chimodzi mwazogwiritsira ntchito mapaipi athu ndi ntchito zozimitsa moto, monga zoyendera pamadzi pozimitsa moto, chitetezo cha waya wamagetsi pamakina oyaka moto ndi zina zotero.
Chonde dziwani, mapaipi achitsulo a ductile, mapaipi amkuwa, mapaipi a aloyi, mapaipi ophatikizika, chitoliro chachitsulo cha kaboni, ndi zina zambiri amagwiritsidwa ntchito pozimitsa moto. Zofunikira za kukula ndizosiyana ndi mapaipi azinthu zambiri ndipo zimakhala ndi zofunikira zawo zapadera. Mapaipi ozimitsa moto nthawi zambiri amafunika kupakidwa utoto wofiira kapena bwalo lofiira. Kusiyanitsa ndi mapaipi ena.
Pochita ntchito zenizeni, mbali zosiyanasiyana za chitetezo cha moto zimakhala ndi zofunikira zosiyana za mitundu ya chitoliro ndi zipangizo, monga: mapaipi apamwamba m'mapaipi amoto m'nyumba, pamene dongosolo likugwira ntchito ndilocheperapo kapena lofanana ndi 1.20MPa, mipope yotentha yovina zitsulo. angagwiritsidwe ntchito; Pamene kuthamanga ntchito ndi wamkulu kuposa 1.20MPa, otentha-kuviika kanasonkhezereka zitsulo chitoliro kapena otentha-kuviika kanasonkhezereka zitsulo chitoliro ntchito; pamene dongosolo ntchito kuthamanga ndi wamkulu kuposa 1.60MPa, otentha-kuviika kanasonkhezereka msomali chitoliro ntchito.
Kugwiritsa ntchito
Chitoliro chopanda chitsulo chopanda ntchito cha ASTM A106, choyenera kutentha kwambiri
