The quality of PE pipes produced in the market is uneven, and many unscrupulous merchants use inferior products to deceive many users. Therefore, when purchasing products, it is important to observe the quality of PE pipe usage to avoid being deceived and causing losses to you.
1、 The appearance of the product should have a lubricating and smooth coating layer, without scratches, cracks, pinholes, or adhered foreign objects when using excellent plastic coated steel pipes. The outer coating of the steel pipes for fire protection should be red, while for water supply, it should be black or gray. The outer layer of the steel pipe should also have clear and durable symbols, and neatly represent the product model, performance specifications, production company trademark or name, production date, production batch number, etc.
2、 The thickness of the product, PE pipe, is mainly used to distinguish the degree of use and manufacturing technology of the product. The thickness of the product needs to be within the standard range, and there should be no significant difference in thickness testing of different cross-sections, in order to clarify that it is a finely manufactured product.
3： The pinholes in the plastic coating layer of the product are mainly used to check the stability of the product. It is necessary to use an electric spark inspection instrument to take specimens from various parts of the surface and inside the meter for inspection. If no electric spark occurs after inspection, it is considered a qualified product.
When purchasing PE pipes, it is important to pay attention to the above three aspects, which are very helpful for you to judge the quality of the product. At the same time, it is also important to note that cheap goods are not good, and high-quality products are priced higher.
