Lan Jingling enamel liner, imported enamel, adopts fully automatic electrostatic spray enamel technology to uniformly spray the enamel on the super-dedicated special steel plate after degreasing and shot blasting, sintering at 850 ° C, completely enamel and steel The fusion makes the anti-corrosion, anti-boiling water weight loss, and performance indicators of Hongle's "Lanjingling" liner reach the world-class level.

Ultra-thick environmentally friendly non-fluorine polyurethane with high-pressure overall foaming, uniform foaming, thickness ≥50MM, density of 235KG / M3, super heat preservation performance, and energy efficiency rating in line with national standard (GB21519-2008) level 1.

Oversized anode protection. The high-quality anode magnesium rod configured at 1.35 times the German DIN4753 standard is more than 100% larger than the anode magnesium rod of a general electric water heater, thereby effectively improving the anticorrosive and anti-scaling performance of the liner.

High temperature and pressure resistant, super thick and high quality steel plate. 2.5 ~ 3.5mm high-quality super-strength special steel plate, formed by fully automatic rolling machine, and imported program-controlled welding equipment, to ensure the excellent pressure capacity of Hongle's "silicon-titanium" liner Fatigue experiment, the burst pressure is up to 45Kgf / cm2). 

High-quality color steel shell. Beautiful and durable, waterproof, anti-corrosion and anti-ultraviolet. It can be used indoors and outdoors. The waterproof and dustproof level of the whole machine reaches IP34.
