What is a pipe hydrostatic testing machine?
In the fields of industrial production and scientific research, quality inspection of pipes is a key link to ensure their safety and reliability. Among them,Pipe hydrostatic testing machineAs an important testing equipment, it is widely used in the pressure resistance testing of pipes. This article will introduce in detail the definition, working principle, application fields and related technical parameters of the pipe hydrostatic testing machine to help readers fully understand this equipment.
1. Definition of pipe hydrostatic testing machine
The pipe hydrostatic testing machine is a special equipment used to test the pressure resistance performance of pipes under hydrostatic conditions. It simulates the hydraulic pressure that the pipe may withstand in actual use and detects whether it meets the pressure requirements stipulated in national or industry standards. This equipment is usually used for testing various materials such as plastic pipes, metal pipes, and composite pipes.
2. Working principle of pipe hydrostatic testing machine
The working principle of the pipe hydrostatic testing machine is to apply constant hydrostatic pressure to the inside of the pipe through the hydraulic system, and observe whether the pipe breaks, leaks or other failures within a specified time. The specific workflow is as follows:
| steps | Description |
|---|---|
| 1 | Fix the pipe to be tested on the testing machine to ensure tightness. |
| 2 | Liquid (usually water or oil) is injected into the pipe and gradually pressurized to a set value. |
| 3 | Maintain the pressure for a period of time and observe whether there are any abnormalities in the pipe. |
| 4 | Record test data to determine whether the pipe meets the standards. |
3. Application fields of pipe hydrostatic testing machine
Pipe hydrostatic testing machines are widely used in the following fields:
| Industry | Application scenarios |
|---|---|
| plastic pipe | Test the pressure resistance performance of PE, PVC, PPR and other plastic pipes. |
| Metal pipes | Test the pressure-bearing capacity of metal pipes such as steel pipes and copper pipes. |
| Composite pipe | Evaluate the performance of materials such as aluminum-plastic composite pipes and steel-plastic composite pipes. |
| Scientific research institutions | Used for new material research and development and pipe performance research. |
4. Technical parameters of pipe hydrostatic testing machine
Different models of pipe hydrostatic testing machines have different technical parameters. The following are common parameter ranges:
| parameters | range |
|---|---|
| pressure range | 0.1MPa~100MPa |
| Test pipe diameter | 10mm~2000mm |
| Test temperature | Room temperature~95℃ |
| Control method | Manual/automatic |
| data logging | Display and store test data in real time |
5. Suggestions for purchasing a pipe hydrostatic testing machine
When purchasing a pipe hydrostatic testing machine, you need to consider the following factors:
