2. Observe the thread length and galvanizing degree of the pipe fittings. Generally, the thread of the poor quality pipe fitting is relatively short. In order to prevent the pipe fittings from decaying, the good pipe fittings will have a good galvanization on the surface of the pipe fittings. Galvanizing is performed before the thread is machined. Heated galvanized, then threaded, and the bad fittings are first galvanized after threading, or replaced with other paints, so the cost is low but the anti-corrosion effect is not good, and the pipeline will rust after installation.
3. Look at the weight of grooved pipe fittings. The outer diameter of grooved pipe fittings produced by cutting corners and materials will become smaller, the thickness of the pipe wall and the size of the pipe will change. The overall weight should be light, and we can also determine the ditch through the weight. Slot tube quality is good.
The above methods are the simple method of identifying quality when people purchase, and of course professional knowledge. When purchasing products, we must buy manufacturers with good qualifications. Do not try to buy cheap products. Good products affect the use of results.
