High accuracies on specified tolerances will avoid rework at site.

Quality of the work is easier to manage and maintain in a controlled environment.

The specialist fabricators work under defined set of quality management criteria to ensure the accuracy of fabrication in order to achieve the proper fit at site and to maintain the required technical parameters defined by the client.Ĭost Savings in Pre-Fabrication, Inspection and Testing

The fabrication of these spools is normally performed by specialist fabrication companies which are equipped with the required infrastructure.

Pipe spools are often flanged to facilitate the connection to other spools. Shop Pre-Fabrication of pipe spools is a proven means for reducing field installation costs while providing the highest of quality in the products fabricated. Pipe rolling machine in Pre-Fabrication shop Image.Why pipe spools are pre-fabricated. To minimize number of position fitting and welding is one of the goals of pipe spool fabrication sequencing. As a result, position fitting and welding usually takes more time to finish than roll fitting and welding. In such case, the fitter or the welder has to move around the main pipe run to accomplish fitting or welding. Roll fitting and welding means the main pipe can be turned by a rolling machine and the fitter or the welder does not have to change his position to perform the operation, whereas position fitting and welding occur when one or more branches of the main pipe exceed the clearance limit. Spool fitting and welding can be grouped into two types. permanent connected) before it comes back to the fitting table and gets fitted with other spool components. The resulting sub-assembly (part of the final pipe spool) continues with welding operations (i.e. Raw pipes are cut to the required sizes and moved with pipe fittings to a fitting table, where some of the components are fitted together (i.e. elbows, flanges, tees, etc.) in fabrication shops. Pipe spools are fabricated from a number of raw pipes and pipe fittings (e.g. Timely supply of pipe spools to module yard and installation site is the key to the success of whole project! Pre-Fabrication of Pipe Spools and site installation. As such, piping work is divided into two stages. Due to compressed schedule and limited space on site, industrial construction projects rely heavily on the offsite fabrication and assembly. This type of construction involves intensive piping, which connects a variety of equipments and conveys process fluid and gas.

Industrial construction includes a wide range of projects, such as petroleum refineries and chemical and power plants.
