What Are The Product Standards For Stainless Steel Pipe Fittings?

What are the product standards of Stainless Steel Weld Fittings?

1. Surface smoothness: Polish the inner and outer surfaces of the pipe fittings to make the surface of the pipe fittings bright, which is also what we often call a mirror. The core purpose is to prevent the liquid substances in the pipeline from causing wall-hanging, long-term pollution, and blockage in the pipeline.

2. Passivation layer: After the polishing is completed, the stainless steel pipe fittings need to be placed in the passivation tank for soaking, and the surface of the pipe fittings is oxidized to form a passivation layer with the acid and alkaline passivation liquid to achieve the anti-corrosion effect of the pipe fittings.

3. Oil repellency: After passivation, oil-resistant cleaning is performed to remove oil stains on the surface of the pipe fittings. After completion, an oil analyzer should be used for inspection. The purpose is to prevent the wall thickness itself from causing oil stains caused by liquid substances flowing through the pipeline.
