Aluminum alloy anode

Aluminum Alloy anodes are the most commonly used Al -Zn-In and Al-Zn-Hg anode,cathode protection for seawater in the ship, port and marine facilities, sea water cooling system and sedimentary water site structures.

Cr Mo steel axis

Cr(Cr) chromium molybdenum and molybdenum(Mo) and iron (Fe) and carbon(C) alloy. Good hardenability deep hardening, rather than surface quenching of saw proof locks on the market.

Flexible joint design

Positive 180°+lateral 360°. In order to make it adapt to the application of various 360 difficulities, the key practical operation is easy and convenient, and the use efficiency is high.
