How to choose double-wall corrugated pipes

1. When we choose double-wall corrugated pipes, we must first check whether the product has a quality inspection report, certificate, and health license. Usually, regular and qualified products have these logo certifications. If not, the product is likely to be fake. When purchasing, we should also check whether the product quality inspection label indicates the production batch number, nominal pressure, trademark specifications and other relevant information.

2. When selecting pipes, we can use tools such as vernier cards to measure the wall thickness of the pipe. If the wall thickness of the product is uneven, the product quality is not very good and you should not buy it. We can also observe whether there are color differences, variegated spots, bubbles, pits and other problems on the surface of the product. Products with these problems cannot be purchased.

3. When purchasing double-wall corrugated pipes, we can smell the product to see if there is any odor. Usually high-quality products will not emit obvious odor. During the purchase process, we can also use our feet to step on the pipes. High-quality products are resistant to pressure and impact. When people stand on the pipes, the pipes are not prone to dents, etc.
