Product Description:

Our stainless steel inner tank complies with China national standard GB/T20289 & QB/T4101, made of food-grade SUS304 stainless steel, nickel welding, pass strict hydrostatic & burst pressure test, fit global 110V/220V storage electric water heater.

FAQ:

Q1: What stainless steel grade do you use for inner tanks?

A1: Mainly SUS304 food-grade stainless steel, customized SUS316 for high-chloride water area.

Q2: Is your tank material anti-rust and anti-corrosion?

A2: Yes, with surface passivation treatment to resist scale and water corrosion.

Q3: Is the raw material food contact safe?

A3: All raw steel complies with food-grade stainless standard.

Q4: Will inner tank rust easily after long-time usage?

A4: Proper water + magnesium rod protection ensures long anti-rust lifespan.

Q5: Are the inlet & outlet ports integrally formed?

A5: Cold/hot water nozzle one-piece stamping forming, no secondary welding.

Q6: Will welding seam leak after long-term water soaking?

A6: Every tank passes 100% airtight hydrostatic test before delivery.
