![]() ![]() ![]() 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. ![]()
