First look at the performance standards for fiber cement pipes
Foreign countries have very strict standards for fiber cement pipes, so the quality of imported products is relatively high. We can feel the quality of the fiber cement pipe. Generally speaking, the weight of the fiber cement pipe is relatively high; the pipe body can not be pointed, and the tip is easy to injure, especially the three ends of the handle end of the fiber cement pipe, the lock tongue and the lock body; Good fiber cement pipes are flexible to open, high in sensitivity and long in service life. Fiber cement pipes also have a variety of styles, so be sure to keep in line with the style of the cable.
Next, look at the fiber cement pipe material.
The fiber cement pipe material on the market is basically divided into asbestos, cement and fiber. Asbestos has high strength, strong corrosion resistance and no discoloration. It is the best pipe-making material; cement is more versatile, mechanical properties are superior, and the price is higher; fiber cement pipe high-quality fiber is strong and wear-resistant, corrosion-resistant, and easy to form. Mostly used for mid-range tubes.
Look again at the surface treatment of fiber cement pipes
The surface treatment is roughly divided into three types: electroplating, spraying and coloring. The fiber cement tube forms a dense protective film on the surface of the product through surface treatment, which acts as anti-corrosion and anti-rust, and makes the fiber cement tube more beautiful and durable. The dense protective film is also a standard for measuring the quality of fiber cement pipes. The fiber cement pipes of good quality are mostly plated, the coating is fine and smooth, even and moderate, the color is bright, and there are no signs of bubbles, rust and oxidation.
