What Is Pipe Spool Fabrication?

Industrial construction covers a wide range of projects. From oil refineries to chemical and power plants. Industrial construction requires a lot of piping to connect a wide range of equipment and process fluids and gases. The spools for this piping are prefabricated in the fabrication shop through a series of cutting, beveling, welding and other processes. Spool fabrication is a critical stage in the pipework, but also in an overall industrial construction project. The assembly must be precise and there is no room for error.

Pipe coils are fabricated off-site to reduce assembly time with various raw pipes and pipe fittings.

These include flanges, elbows, tees and more. Raw pipes are pre-cut to precise sizes, along with pipe fittings and other components. They are temporarily joined together and this semi-finished assembly is welded to other coil components. The pipe spooling process can be divided into two phases; spool roll fitting and welding and spool permanent position fitting and welding.

Key Takeaways about pipe spool fabrication:

• It is done off-site in a controlled environment.
• Construction time is reduced.
• The quality of the work is easier to manage.
• Factory fabrication minimises production delays.
• C&N’s pipe fabrication facility has decades of experience in meeting customer specifications, completing demanding assemblies and delivering on time.

Spool roll fitting and welding uses a rolling machine to rotate the main. The fitter does not need to change position to perform the task. With coil roll fitting and welding, parts of the main pipe go beyond the clearance limit. This forces the fitter to move around the main pipe to complete the fitting and welding process. This makes spool position fitting and welding a longer process than spool roll fitting and welding. Reducing the number of spool position fittings and welds is one of the objectives of the spool manufacturing sequence.

Pipe Spooling Application

Industrial projects such as power stations and oil refineries require extensive pipework.

These industries require a wide range of equipment to be connected to carry and transport processed liquids and gases.

Due to space limitations on site and the need to complete construction quickly, industrial construction projects rely heavily on off-site fabrication and installation.

There are two stages to this process – spool fabrication and site installation.

Why Are Pipe Spools Prefabricated?

Prefabrication of spools is a proven means of reducing field installation costs. It also ensures the highest quality of finished products. Pipe coils often need to be flanged to connect to other coils. The fabrication of these spools and their components is typically carried out by fabricators with the necessary infrastructure. Specialist fabricators work to a defined set of design and quality management criteria to ensure the accuracy of fabrication and to achieve the correct fit on site.

Cost savings in prefabrication, inspection and testing

• Work quality is easier to manage and maintain in a controlled environment.
• Factory fabrication minimises production delays.
• Prefabricated coils address the severe skills and labour shortages. In addition, there’s no need to dedicate a significant amount of labour to spooling on site.
• Mass production results in lower manufacturing costs compared to custom fabrication.
