What are pressure pipelines?
Pressure pipelines are a type of specialised equipment used to transport fluids and gases under pressure. They are commonly used in mining operations to carry water, slurry, and other materials. In the petrochemical industry, pressure pipes are used to carry oil, natural gas, and other chemicals. Pressure pipelines are used in coal seam gas extraction to carry methane and other gases from the coal seam to the surface.
To keep the liquids and gases flowing, the pressure of the pipeline has to be increased and constantly kept within a certain range depending on the viscosity of the resource being transported. The increased pressure can cause the pipe to fail if it’s not strong enough, which is why high-pressure piping solutions are manufactured using carbon steel or stainless steel due to its strength and flexibility.
How are pressure pipes fabricated?
Steel fabrication of pressure pipes is a complex process that requires precision and care. Pressure pipelines used in the mining, petrochemical and coal seam gas industries are subject to extremely high pressures. To ensure their safe operation, these pipelines must be made from sturdy materials in exact accordance with the fabrication requirements so they can withstand the demanding environment.
First, the pressure pipe must be designed to meet the specific industrial application. This means the pressure pipe must be strong enough to withstand the pressure of the fluid or gas it will be carrying, and it must be able to resist corrosion. Once the pressure pipe has been designed, it is then cut to length and welded together.
The process of welding piping components is critical, as even a small leak can cause problems. After the pressure pipe has been welded together, it is then thoroughly tested to ensure that it can withstand the pressure it was designed for. Only after the pressure pipe has passed all these tests is it ready for use in the field.
Quality control is a crucial aspect of the pressure piping fabrication process. Failures of high pressure pipelines can be catastrophic and even minor defects could seriously compromise the structural integrity of the pipe work. All piping equipment undergoes rigorous testing to ensure it performs under operating loads, pressure testing loads and other conditions as outlined in the project requirements.
