Product Q&A

Q:What causes white rust on galvanized pipes and how to handle it?

White rust is caused by zinc layer oxidation in humid environments. For slight rust, wipe with a dry cloth and apply anti-rust oil. For severe rust, clean with 5% dilute hydrochloric acid, rinse with water, and dry. Store in ventilated, dry areas.

Q:How to handle zinc layer loss during welding of galvanized pipes?

Polish the welding area to remove the zinc layer within 50mm on both sides before welding. Apply zinc-rich coating to the weld area afterward. Use low-temperature welding or special galvanized welding rods to minimize zinc evaporation.

Q:Can galvanized pipes be directly buried underground?

Yes, but precautions are needed. In ordinary soil, the zinc layer protects for 5-10 years; wrapping with anti-corrosion tape is recommended. In acidic or saline-alkali soil, apply an epoxy coal tar anti-corrosion layer or use PE coated pipes.

Q:How to connect galvanized pipes with stainless steel pipes?

Use insulation connections like nylon gaskets or rubber bushings to isolate metals. Alternatively, use bronze flanges or stainless steel conversion joints. Installing magnesium alloy sacrificial anodes at the end of galvanized pipes is also effective.

Q:What are the standard specifications and dimensions available?

Standard specifications include diameters of 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, and 60mm. Wall thickness ranges from 1.0mm to 20mm. Standard length is usually 6 meters, but customized lengths are available.
