A spool is an assimilation of piping components, which is prefabricated in a piping shop, for installation in the field. They are often flanged to facilitate the connection to other spools.The fabrication of these spools in the advanced countries is normally performed by specialist fabrication companies which are equipped with the required infrastructure. In India, this activity is predominantly done at site by employing huge labor force and semi – automatic machines. Although this activity appears relatively straightforward, the specialist fabricators have the necessary wherewithal to do so in a consistently accurate manner.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 clients.
Advantage of spool
• Quality of the work is easier to manage & maintain in a controlled environment. Highaccuracies on specified tolerances will avoid rework at site.
• Weather independent fabrication will minimize production delays.
• Prefabricated Spools are the perfect answer to severe skill & labor shortage. Users do not have to mobilize significant work force for fabrication of spools on site.
• Economies of Scale will result in lesser costs of fabrication in mass production vis – a – vis on – site fabrication.
• Prefabricated Spools will take lesser fabrication / assembly time, thereby avoiding time & cost overruns.
• Prefabricated Spools will entail no or little investments in fabrication & testing equipments by users. Radiography, PMI, MPI, Ultrasonic tests, Hydro tests etc. can be performed better & effectively in controlled environments.
• Prefabricated Spools will be serviced under the strict vigilance of Third Party Inspection Agencies, ensuring 100% adherence to required quality standards.
• Better control on welding parameters in controlled environments resulting in lesser probability of rework at site.
