Kev ntseeg scaffolding chaw tsim tshuaj paus nrog 20+} xyoo dhau los.
Cov kws tshaj lij hauv Ringlock, Cuplock, thav ntawv, thiab hlau cov khoom. Customizable Systems, Kev them nyiaj yug thoob ntiaj teb.
BS 1387 Qib Carbon Volas Seamless Tubes, feem ntau lees paub cov kav hlau me me thiab cov leeg, sawv cev rau ib qeb ntawm tus nqi- cov leeg roj carbon monoxial. Cov hlab no yog cov cim los ntawm cov ntsiab lus carbon txog li 0.20% thiab cov ntsiab lus manganese ntawm li 1.20%, tso lawv cov kev tsim nyog thiab ua kom zoo nkauj. Tsim rau nruj ua raws li BS (British Txuj Ci) Kev paub meej, lawv tau paub dav hauv cov voj kev lag luam raws li CS (carbon hlau) kav dej lossis hlau me) kav dej.
Tshwj xeeb, qis {- @} Cov kav hlau steel ua kom pom kev nyuaj dua piv rau qhov siab me me. Txawm li cas los xij, lawv cov hardness nto tuaj yeem txhim kho los ntawm cov txheej txheem hu ua carburizing, uas diffuses carbon rau hauv txheej txheej sab nraud ntawm cov khoom. Qhov kev sib xyaw ua ke ntawm kev pheej hmoo, kev ua haujlwm, thiab lub peev xwm rau kev ua kom tawv nqaij bs 1387 qib qib ua rau tsim nyog rau ntau yam kev siv cov khoom siv.
