Centrifugally cam khwb cia hlau yeeb nkab yog tsim los ntawm spherical graphite cam khwb cia hlau los ntawm centrifugal spinning txheej txheem.Cov kav dej, uas muaj peev xwm xa tau ntau yam kua dej xws li dej, roj thiab roj, yog dav siv nyob rau hauv ntau yam pipeline tej yaam num rau metallurgy, mine, dej txuag, roj av. thiab kev pabcuam pejxeem hauv nroog.
1. Muaj lub zog muaj zog, zoo toughness li steel thiab zoo corrosion kuj zoo li steel, uas yuav pab tau lawv tiv thaiv poob siab thaum lub sij hawm thauj mus los, installation, tuav thiab siv.
2.Cov yeeb nkab hlau yog qhov zoo tshaj plaws hloov rau grey cam khwb cia hlau yeeb nkab thiab cov yeeb nkab steel.
3.Cov kav dej DI yog tsim nrog zoo ncaj, txawm phab ntsa tuab, siab qhov tseeb, du nto tiav thiab zoo kawg nkaus txhua yam khoom, ntxiv nrog rau ruaj khov rau sab hauv & sab nraud txheej txheej.
4.Flexible Push-in sib koom tes thiab roj hmab gasket yog siv los ua kom yooj yim installation ntawm cov kav dej.
5.Lawv yog qhov kev xaiv ruaj khov dua, vim lawv feem ntau yog tsim los ntawm cov khoom siv rov ua dua tshiab, uas yog qhov tseem ceeb ntawm qhov kev xav ntawm ib puag ncig.
6.Inside diameters loj dua li feem ntau, nce ntws, uas txo cov kev siv hluav taws xob thiab siv cov nqi siv lub sij hawm
7.Lawv muaj lub zog tawg siab, uas yog tsim rau kev siv siab siab.
