Electrode Material
Material Symbol Anti-corrosion
SS316L V Suit for industrial water, domestic water, sewage water and other acid liquid etc.
Titanium Ti Suit for Sea water, chloride, hypochlorous
Hoag's alloyC Hc Bears the oxidized acid, like nitric acid, nitration mixture, chromic acid and sulfuric acid mixture. Also bears the oxidized salts or other oxidant environment corrosion. To the sea water, the alkaline solution, the oxide compound solution have the good inoxidizability. 
Hoag'salloy B Hb To the sulfuric acid, the phosphoric acid, the hydrofluoric acid and so on non-oxidized acid, the alkali salt have the good corrosion resistivity  。
Tantalum Ta Besides hydrofluoric acid, nearly ability all chemical mediator corrosion. Because its price is expensive, only uses in the hydrochloric acid and the strong sulfuric acid  。
tungsten carbide W Has the outstanding wear-resisting performance, uses in attrition medium specially and so on mud, paper pulp. 
Lining Material Selection
Lining material Anti-corrosion Working temp. Application area
 (Ne) Bears the general low concentration acid and alkali salt the corrosion 0~70℃ Uses in the process water, the sewage, the low concentration acid and alkali salt brine. May reach most greatly according to the request 95℃.
DN50~DN2000 may choose the Ne lining material.
 (FEP) Heat-resisting,the inoxidizability is good, the mechanical strength is high, the anti-attrition performance is good, cleans up when the surface is not easy to damage the inside lining.   

Besides the mortar and so on strong wearability medium's all fluids, may use in likely the tap water place hygienic request, may reach most greatly according to the request 180℃.
DN6~DN400 may choose the FEP lining material 
(PTFE) May resist all chemical mediator nearly the corrosion, the wearability is bad  -40~180℃ Cannot use in the negative pressure pipeline and the wearability strong fluid.
DN25~DN1000 may choose the PTFE lining material.
