Information

The traditional stainless steel liner has defects such as easy corrosion, easy to absorb and collapse, and poor pressure-bearing performance. The advantage of the enamel liner is that it has the characteristics of pressure-bearing and durable, anti-corrosion, anti-absorption, water resistance and heat resistance. At present, it is more widely used in the field of electric water heaters.

There are many differences between water heater enamel liner and ordinary enamel utensils, especially in terms of manufacturing process, material requirements and equipment and facilities for making water heater enamel liner.

(1) Selection of steel plate materials: Hot-rolled steel plates, cold-rolled steel plates or low-carbon and zero-carbon steel plates with a thickness of 1.5~5mm are usually used, and special steel plates for enamel are used. high.

(2) Welding: The main purpose of the water heater enamel liner is to weld the joint between the head and the barrel, which depends on the size, process and equipment of the water heater liner.

(3) Common defects: one is enamel defects that reach the metal substrate, such as pinholes, cracks, cracks or peeling porcelain, which are conductive and consume protective current; the other is recessive defects, These are metal oxide-rich spots inside the enamel. Appearing to be a dark brown or black origin, this recessive defect may conduct electricity and may consume protective current.
