1.Pipe Spool Production

2.Site Installation

Pipe spools are produced by the usage of raw pipes and pipe fittings. The cutting process of the raw pipes is done with prespecified sizes that are suitable for the pipe fittings and other components.

There are two main parts of pipe spooling process:

1.Roll correction and welding

2. Durable position fitting and welding

Pre-Fabrication of Pipe Spools

Roll correction and welding process are fitting of the main pipe by rolling machine and the welder does not need to change his situation, and also the position of fitting and welding occur when more than one branch of the long pipe overcome the clearance limit. To create a more efficient piping system and save time, pipe spool pre-fabrication is used. Because if the system did not produce preliminary, the welding of the system will take much more time and the welder has to move over the main pipe to accomplish fitting or welding.

Why pipe spools are pre-fabricated?

Pipe spools are pre-fabricated to reduce field installation costs and provide higher quality in the products. They are generally flanged to obtain the connection to other spools. The spool fabrication is normally performed by special companies having the required infrastructure. These specialist fabricators produce the system under the specified set of quality and accuracy to obtain proper fit at the site and to maintain the necessary technical properties defined by the client.

Mainly used pipeline systems are generally;

Steel pipes

For the supply of water and flammable gases, steel pipes are the most useful pipes. They are used in many homes and businesses to transfer natural gas or propane fuel. They also used for fire sprinkler systems due to their high heat resistance. The durability of steel is one of the best advantages of the pipeline systems. It is strong and it can withstand the pressures, temperatures, heavy shocks, and vibrations. It also has unique flexibility which provides an easy extension.


  • In controlled environments, the quality of the work is easier to manage and maintain.
  • Specified tolerances avoid rework at the site because of high accuracy.
  • Fabrication is weather independent, so it minimizes the production delays.
  • The pre-fabrication process is the best advantage because it provides less workforce for the fabrication of spools on site.
  • Mass production manufacturing results in lower manufacturing costs in comparison with site fabrication.
  • Lesser fabrication and assembly time needed for pre-fabricated spools, with this way, extra time and cost wastage is avoided. 
  • Pre-fabricated spools want little investments in production and testing equipment by the users. For better and efficient performances, Radiography, PMI, MPI, Ultrasonic tests, Hydro tests, etc. can be used.
  • To obtain a lesser probability of rework at the site, better control of welding parameters must be done in the controlled environments.
  • Power availability is not necessary.
  • Unnecessary time delays are avoided.


Making pipe spools has wonderful benefits but the main disadvantage is the not fitting on site. This problem causes terrible results. One small mistake in the pre-production of pipe spools causes a non-fitting system in the working environment and creates a huge problem. When this problem occurs, pressure tests and x-rays of the welds must be checked again and re-welding should be needed.
