11/16 Polyurethane Tubing

Yantai Zhengyuan Polyurethane Co., Ltd. was established in 2007 and has been committed to the research and development, production, and sales of polyurethane products since it was established. The products produced are mainly used in industries such as industrial automation, petroleum, mining, coal mining, automobiles, logistics, and large machinery. After nearly 20 years of development, we have accumulated rich experience in producing 11/16 polyurethane tubing. The 11/16 polyurethane tubing produced has received unanimous praise from customers for its high-quality quality and low price.

11/16 polyurethane tubing is a flexible hose made of polyurethane elastic system, which has characteristics such as good elasticity, wear resistance, corrosion resistance, low temperature resistance, and dimensional stability. In many applications, PU hose has become an essential piping system. However, many people may have some doubts about the wall calculation method of PU hose. This article will briefly introduce the calculation method for the pipe wall of PU hose and explain some key points for its use.

1、 Calculation method for PU hose pipe wall

The calculation method used for the pipe wall of PU hose is similar to that of other pipelines, which requires consideration of factors such as the flow rate, pressure, temperature, and material of the internal medium in the pipeline. PU Hoses are generally used as pipelines for conveying low-pressure gases, liquids, or particulate matter. Such as water, oil, corrosive gases, etc. Therefore, the calculation method for PU hose pipelines is relatively simple, and the following calculation formula can be used:

When the pressure inside the pipeline P ≤ 0.5Mpa, the following formula can be used for calculation:

Wall thickness t=PD/(2fs)

Among them, P represents the pressure inside the pipeline, D represents the inner diameter of the pipeline, f and s are the deformation coefficient and tensile strength of the pipeline material, respectively, and t represents the wall thickness of the pipeline. When calculating the wall thickness of PU hose pipelines, it is necessary to consider the mechanical factors that they may experience during use, such as pressure, tension, and bending, to ensure the service life and stability of the pipeline.
