About inner Enamel Tank
Huayang inner Enamel Tank adapts good material,advanced equipment,rigid welding,enamel process,Compared the fist generation inner tank with galvanization,the sencond generation inner tank with stainless steel,also the common inner tank,the enamel tank more resistant to corrosion, safer and longer life.
1. Good material: Huayang enamel inner tank use baogang steel, imported enamel power from USA Ferro,commpared other common enamel material,the quality assurance  is stronger.
2.Strong ability resistance to pressure: Pass the  National  test   of  two hundred and sixty thousands of pressure pulse
3. Resistant to corrosion and incrustation :good seal,resistant to Acid-Alkaline,corrode of hot water, corrosion and sharp change of temoeture
4. Enamel high adhence: according with USA standard test:steel bar strike enamel steel sheet, the  strike net surface is same as the USA First-grade standard, so the result arrive the USA first-grade standard

                 
According with USA standard to strike the enamel steel sheet , the strike surface black shows that the base enamel or the white surface showes base enamel seperate steel sheet competely.Compared the below strike pictures,huayang enamel steel sheet adhence ability arrive the first grade adhence steel sheet competely,

 

 

 

Our tank advantage:
●coil is Under-mounted, which can heat the whole inner tank, avoid the problem that  the most of botten  water cant be heated which use centered coil
●Length coil ,enlarger the heat exchange area, improve the heat exchange efficency

 

 

●Standard Tank made of enamelled carbon steel with a large surface bare-tube heat exchanger.

●Enamelling in accordance with DIN4753 Part 3 on the inside,primer applied to the outside.

●Mangnesium protection anode of G1 1/4”provided for completion of the cathodic corrosion protection in accordance with DIN 4753 Part 6.

●The temperature probed can be placed in variable positions due to the use of sensor terminal blocks.

●Inclusive G11/2”bush for electrical heater.

●All external threads are flat sealing.

●CFC free soft PU-foam insulation with a thickness of 75mm and a PVC coating ,bottom insulation included,in accordance with DIN 4753 Part 8,RAL colours white RAL9010,grey RAL9006,red RAL2002,orange RAL2004,blue RAL5015.
●Compressive strength 8bar.
●Woking under pressure, comfortbale and healthy
●Heating inteligently, supply hot water 24 hours all the climate, easy operation,more convenient with one key to start
