A pressure pipe is a pipe used to transport liquids and gases under pressure. Pipes are considered pressure pipes only if their operating pressure is greater than 0.1 MPa, their diameter is greater than 50 mm, and the medium they transport is above its boiling point. Pressure pipes are divided into three types and four categories. The following details the pressure pipe classification.

Pressure Classification

High-pressure pipelines: 0.1 ≤ P < 1.6, used for urban water supply
Medium-pressure pipelines: 1.6 < P ≤ 10, used in the chemical industry or for natural gas transportation
High-pressure pipelines: 10 < P ≤ 100, used for oil and gas transportation
(Ultra-high-pressure pipelines: P > 100, used for scientific research or for transporting critical fluids.)

Risk Classification

Long-distance pipelines (GA): Trans-regional oil and gas transportation.
Public pipelines (GB): Urban gas and heat pipelines.
Industrial pipelines (GC): Internal process pipelines.
Power pipelines (GD): Power plant steam pipelines.

How to Select the Right Pressure Pipe

Choosing the right pressure pipe requires consideration from a number of perspectives.

Firstly, the environmental conditions of the application need to be considered, different environmental scenarios require different materials, grades and pressure levels of steel pipe products. Secondly, the strength and temperature of the working conditions need to be considered. Thus, the material of the pressure pipe is selected to suit the environment.

Thirdly, it is necessary to consider whether the installation and maintenance of the pressure pipe can be sustained. Finally, the project as well as the product should be analysed for cost effectiveness.

The above factors are crucial in selecting the perfect pressure hose.

FAQs

Can PVC pipe be used for pressure?

PVC piping is not recommended for high pressure conditions. The ability of PVC pressure pipe to withstand pressure is relatively low, and it is generally used for low pressure or moderate pressure applications. Generally speaking, the maximum rated temperature of PVC pipes is usually 140 degrees Fahrenheit, and if the air circulating in the pipes reaches 110 degrees Fahrenheit, an explosion may occur. Therefore, for high pressure applications, PVC piping is generally not recommended.

How to test the pressure pipe?

Generally, pipe pressure is measured using a pressure gauge or pressure sensor. After the appropriate instrument is selected and installed, zero calibration is performed, pressure reading is performed, and pressure data of the pipeline is monitored. It is important to note that when measuring pipe pressure, it is necessary to ensure that the instrument is properly installed and calibrated, and that the pipe itself is safe and stable.

How does the pressure tube work

Pressure tubes generally increase their own pressure through the height of the liquid and the action of gravity. The flow rate of the liquid will also affect the operation of the pressure pipe. In addition, increasing the length of the pipe will also increase the friction of the fluid in the pipe. Will reduce the pressure of the pressure pipe.
