Enamel Coated Flange Heating Element Fast Heating High Thermal Efficiency Compact Enamel No Peeling Off

Technical Parameters:

Product Description:

This enamel coated flange heating element is premium choice for 6L&10L under-sink water heater especially for hard limescale water area. Made of SUS304 base tube with high-temperature sintered black enamel coating to effectively reduce scale corrosion and prolong service life. Standard power 1500W/2000W, available for 220V domestic and 110V export custom order. Standard Φ63 flange fits most small boiler inner tank, reliable insulation against leakage, ideal for hard water area domestic & Southeast Asia market, widely used for original assembly and maintenance replacement.

Distinguishing Features vs. Standard Stainless Steel Heating Tubes: The outer surface of the tube body features a high-temperature enamel anti-rust coating that offers superior resistance to limescale and corrosion. Its high surface hardness inhibits scale formation, making it ideally suited for regions with poor water quality or heavy limescale accumulation. It is commonly utilized in small-capacity (6L/10L) under-sink water heaters.

FAQ:

Q1: What is the base material of enamel heating tube?

A1: Base pipe is SUS304 stainless steel, outer surface covered with high-temperature sintered black enamel coating.

Q2: What’s the thickness of enamel coating layer?

A2: Standard enamel thickness 0.08~0.15mm, compact and high adhesion strength.

Q3: Why enamel coating can anti limescale better than bare stainless steel tube?

A3: Enamel smooth glaze surface reduce mineral adhesion, hardly form thick scale under hard tap water.

Q4: Will enamel peel off after long-time hot & cold water alternation?

A4: High-temperature sinter craft ensure tight combination between enamel and steel base, normal use no peeling.

Q5: Will enamel heating tube cause electric leakage after long service?

A5: Compact MgO filling + sealed tube mouth + intact enamel layer, effectively prevent leakage under normal use.

Q6: Does enamel layer affect heating efficiency?

A6: Thin uniform enamel has negligible impact on heat transfer, keep high heating efficiency same as stainless tube.
