What is the plastic pipe ring stiffness testing machine?
In today's rapidly developing construction and engineering fields, plastic pipes are widely used because of their lightness, corrosion resistance and low cost. However, the quality and performance of plastic pipes are directly related to the safety and durability of the project. In order to ensure the quality of plastic pipes, the ring stiffness testing machine has become an indispensable testing equipment. This article will introduce in detail the definition, working principle, application fields and related data of the plastic pipe ring stiffness testing machine.
1. Definition of plastic pipe ring stiffness testing machine
The plastic pipe ring stiffness testing machine is a device specially used to test the stiffness of plastic pipe rings. Ring stiffness refers to the ability of a pipe to resist deformation when subjected to external pressure, and is an important indicator of the pressure resistance of a pipe. Through the ring stiffness test, the load-bearing capacity and durability of the pipe in actual use can be evaluated.
2. Working principle
The plastic pipe ring stiffness testing machine simulates the external pressure endured by the pipe in actual use and measures its deformation, thereby calculating the ring stiffness value. The specific steps are as follows:
1. Place the pipe to be tested on the support device of the testing machine.
2. Apply vertical pressure hydraulically or mechanically.
3. Record the deformation of the pipe under pressure.
4. Calculate the ring stiffness based on the deformation and pressure values.
3. Application fields
Plastic pipe ring stiffness testing machine is widely used in the following fields:
1.construction project: Used to test the performance of plastic pipes such as drainage pipes and cable protection pipes.
