The prefabricated components of a piping system are called pipe spools. They include the pipes, flanges and fittings, and they are mounted during the fabrication before they are delivered to the construction are. They are delivered pre-mounted so to make them easier to assemble using hoists, gauges, and other tools for assembly. Pipe spools connect long pipes with flanges at the tips so that they can be bolted to another pipe with matching flange. Pipe spools are imbedded into concrete walls before the concrete is poured. The pipe spool has to be positioned properly before concrete is to make sure that it can withstand the weight and force of the concrete as it is poured. This process is important because you will need to go back and run the pipe sometime in the future.
The construction of power plants and petroleum refineries requires intensive piping. These industries need to connect a variety of equipment which will be used to carry and transport processed fluid and gas. Because of limitations of space on site and the need to finish the construction fast, these industrial construction projects have no recourse but to rely seriously on fabrication and assembly performed away from the site. This piping process has two stages – pipe spool production and site installation.
Pipe spools are fabricated using various types of raw pipes and pipe fittings and they include flanges, elbows, tees, and a lot more. They are usually fabricated offsite. The raw pipes are pre-cut to specific sizes and together with pipe fittings and other components. They are temporarily fitted together. This partially finished sub-assembly is then welded with other spool components.
The entire pipe spooling process can be grouped into two:
Carbon Alloy Pipe
Carbon Steel Pipe
Pipe Distributor

Industrial construction includes a wide range of projects, such as petroleum refineries and chemical and power plants. This type of construction involves intensive piping, which connects a variety of equipments and conveys process fluid and gas. Due to compressed schedule and limited space on site, industrial construction projects rely heavily on the offsite fabrication and assembly. As such, piping work is divided into two stages: Pre-Fabrication of Pipe Spools and site installation.
