Pipeline prefabrication: Haihao Group’s secret to improving efficiency and quality

Pipeline prefabrication is a process in which the various parts of the pipeline system are pre-processed, assembled and welded into modules or sections in a factory environment. These prefabricated modules or sections are then transported to the installation site for final connection and installation. This method is widely used in industries such as oil, gas, chemicals, electricity, shipbuilding and construction. As an industry leader, Haihao Group has excelled in the field of pipeline prefabrication with more than 40 years of experience and advanced equipment.

Prefabricated Pipes

Why choose pipeline prefabrication?

1. Scarcity of technical workers: Due to various factors, there is a serious shortage of technical workers willing to work on the construction site. This scarcity affects key technical skills such as welding, making it increasingly difficult to find suitable on-site processing workers.
2. High project costs: Traditional pipeline construction requires prefabrication and installation on site, which is time-consuming and costly. The cost ratio of these processes is about 7:3, and the cost of on-site prefabrication is significantly higher.
3. Unstable quality of on-site prefabrication: The quality of on-site prefabrication is often unstable due to differences in workers’ technical level and quality awareness, which may lead to problems in the final installation and operation of the pipeline system.

Advantages of Pipeline Prefabrication

1. Improve efficiency: The prefabrication processing and welding process in a controlled factory environment is more efficient and accurate, greatly reducing on-site work time and shortening the project cycle.
2. Reduce on-site workload: Prefabrication greatly reduces on-site installation workload and speeds up project completion.
3. Improve quality: Better control of processing and welding quality in a factory-controlled environment reduces quality problems that may occur during on-site installation.
4. Reduce costs: Higher production efficiency, reduced material waste and shortened on-site installation time, the overall project cost can be controlled and reduced.
5. Improve safety: Prefabrication reduces high-risk tasks on site, such as high-altitude operations and construction in complex environments, and improves worker safety.

Process of Pipeline Prefabrication

1.Design and Planning: Carry out detailed design and planning of the pipeline system according to project requirements, and determine the size and connection method of each part.

2.Material Preparation: Purchase the required pipes, pipe fittings, flanges, valves and other materials according to design specifications.

3.Cutting and Processing: Cut and process the pipeline according to design requirements, including groove processing, etc.

4.Assembly and welding: Assemble the processed pipes and pipe fittings into sections or modules and weld them.

5.Inspection and testing: Perform quality inspection and testing on the prefabricated pipe modules, such as weld flaw detection and pressure testing.

6.Anti-corrosion and coating: Perform anti-corrosion treatment and coating on the pipe surface as needed.

7.Transportation and installation: Transport the prefabricated pipe modules to the installation site for final connection and installation.
