1. When purchasing, everyone should check whether the surface of the overall pipe has a luster, whether its color is evenly distributed, whether its inner and outer walls are smooth and flat, and whether there are any bubbles, dents, impurities, etc. It should be noted that these surface defects will affect its performance to a certain extent.
2. Secondly, we need to check whether the product description is complete, whether the pipe body is marked with the relevant manufacturer, brand trademark, production date, product name, specification size, execution standard number, etc., and whether it indicates the nominal outer diameter of the steel pipe, pipe series S, etc., whether the marking is clear and visible, and finally, we need to verify whether the marking is consistent with the actual situation.
3. Due to the high usage of this type of material, when purchasing, everyone should purchase steel pipes of the same brand, specification, and model to ensure consistent performance and installation. This is because different brands of products may have different raw materials, which can have adverse effects on the fusion of pipes and fittings. If used for a long time, it is easy to cause leakage at the fusion joint.
