Enamel Steel Tank, also known as enamel assembly tank, is made of titanium-alloy steel plates with double-sided enamel plating. They have beautiful appearance, easy cleaning and maintenance, with good performance in wear resistance, corrosion resistance, impact resistance, insulation resistance and static proof; No special anti-corrosion treatment required, life-time is designed at 30 years.

Our factory of enamel steel is the production base in China, the location of birthplace of hot-rolled steel with double-sided enamel. While it's the largest and most professional supplier for enamel assembly tank in China, with nearly 30 years of experiences in manufacturing enamel steel. Products are enjoying high reputations internationally, being exported to the United States,Russia,Asia and Africa etc.

Specifications of Enamel Steel Plate:

Tank is equipped with the auxiliaries below for a complete reactor:
 Mounted on top of tank as all-in-one solution of biogas production&storage,the outer&inner membranes of gas holder would be fixed tightly by stirrups around tank;It makes biomass complete contact with microorganism. Three types of stirring methods: Mechanically, Hydraulically and Gas. Among of them,mechanical agitator is the most popular, has three kinds of installation: Vertically,Inclined entering and side entering.To avoid damages for tank and gas holder resulting from too high or too low pressure inside tank;
 Made of Stainless Steel in tube form,it spirals around inside wall of tank. Hot water from
CHP or boiler to be used for tank heating through heating coils.And water after heat exchanged would return to CHP or boiler,as a complete water circulation;
 It is required for UASB/EGSB/IC types of digesters with feedstock of low solid content, to achieve separations of "gas", "liquid" and "solid";
 According to actual process requirements, liquid level sensor,temperature sensor,ph sensor,gas pressure sensor and leaking alarm can be installed or integrated into the PLC monitoring system together with biogas analyzer,flow meter etc;
 For projects located in cold area,heat insulation layer would be installed outside of tank,to keep warm and avoid heat leaking,to guarantee the fermentation temperature;
 Feeding system, discharge system, biogas output pipe, the center support, ladder, casing, manhole, lightning rod, electric control cabinet, blower. Etc.
