Mapaipi Opangidwa ndi Cold, EN10219 S235JRH, S235J0H, S355JRH, S355J0H

Kufotokozera Kwachidule:

Gawo ili la European Standard limafotokoza zaukadaulo woperekera zinthu za kapangidwe kozizira, kopanda kanthu, kozungulira, kozungulira, kapena kozungulira, ndipo limagwira ntchito ku zigawo zopanda kanthu zopangidwa ndi zozizira popanda kutentha.

Cangzhou Spiral Steel Pipes Group Co., Ltd imapereka mapaipi achitsulo ozungulira okhala ndi dzenje lopanda kanthu.

a. Njira yochotsera poizoni m'thupi imatchulidwa motere: FF: Chitsulo chophwanyika bwino chokhala ndi zinthu zomangira nayitrogeni mu kuchuluka kokwanira kumangirira nayitrogeni yomwe ilipo (monga osachepera 0,020% ya Al yonse kapena 0,015% ya Al yosungunuka). b. Mtengo wapamwamba kwambiri wa nayitrogeni sugwira ntchito ngati mankhwala akuwonetsa kuchuluka kwa Al komwe kuli 0,020% ndi chiŵerengero chochepa cha Al/N cha 2:1, kapena ngati pali zinthu zina zokwanira zomangira N. Zinthu zomangira N ziyenera kulembedwa mu Chikalata Chowunikira.

Mayeso a Hydrostatic

Kutalika kulikonse kwa chitoliro kuyenera kuyesedwa ndi wopanga ku mphamvu ya hydrostatic yomwe ingapangitse kuti pakhoma la chitoliro pakhale mphamvu yosachepera 60% ya mphamvu yocheperako yopezeka pa kutentha kwa chipinda. Kupanikizika kuyenera kutsimikiziridwa ndi equation yotsatirayi:
P=2St/D

Kusintha Kovomerezeka kwa Kulemera ndi Miyeso

Kutalika kulikonse kwa chitoliro kuyenera kuyezedwa padera ndipo kulemera kwake sikuyenera kupitirira 10% kapena 5.5% pansi pa kulemera kwake kongopeka, kuwerengedwa pogwiritsa ntchito kutalika kwake ndi kulemera kwake pa unit level.
M'mimba mwake wakunja suyenera kusiyana kuposa ± 1% kuchokera m'mimba mwake wakunja wotchulidwa
Kukhuthala kwa khoma nthawi iliyonse sikuyenera kupitirira 12.5% pansi pa makulidwe a khoma omwe atchulidwa
