Oil pipelines are a type of product that people often use, but there are many inferior products on the market. So how can I buy a product with excellent quality? The following is a professional tubing manufacturer to introduce how to determine the quality of the tubing by looking at the outer surface of the tubing.

First, look at the surface of the tubing: Observe whether the outer surface of the tubing is consistent in thickness. If it is a textured oil pipe, look at the average spread of the cloth, if it is a smooth surface, see if its surface is flat and lubricated.

Second, look at the oil pipe wire layer: observe whether the wire layer display is uniform. You can use your fingers to rub the wire layer and the rubber layer on the surface to judge the connection status. The better product quality is better, and the quality is worse if the connection is not good.

Third, look at the section of the tubing unit: observe whether the hose in the table is offset. In the rubber inside the hose, it is mainly observed whether the inner wall of the inner rubber is lubricated. You can also use your fingers to judge whether the inner rubber is elastic. If the elasticity is good, it indicates that the oil content of the oil pipe is good and the elasticity is low, which means that the oil content of the oil pipe is low and the quality is poor.
