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.
Prefabricated Spools are the perfect answer to severe skill and labor shortage. Users do not have to mobilize significant work force for fabrication of spools on site.
Manufacturing in mass production, will result in lower manufacturing costs compared with site fabrication.
Prefabricated Spools will take lesser fabrication / assembly time, thereby avoiding time and cost overruns.
Prefabricated Spools will entail no or little investments in fabrication and testing equipments by users. Radiography, PMI, MPI, Ultrasonic tests, Hydro tests etc. can be performed better and 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.
Weld less Induction Bends (as permitted by the client) would entail complete avoiding of welding pipe sections using SR elbows, thereby bringing in significant cost savings in welding, radiography of welding joints and material requirements.
Lesser dependency on power availability, avoiding unnecessary time delays.
Improved safety in better manufacturing conditions than on site.
Fabricating spools off site means less slag, abrasive dust, smoke and other contaminants which are unacceptable in highly hygienic food processing and other industries.

Know More

Internal Coating Pipes

Internal coated pipes (epoxy coated). A spraying nozzle has been used to spray the liquid epoxy inside the pipe as per the required thickness. Before applying the epoxy paint, internal surface of the pipe is cleaned. The typical coating thickness for gas pipelines varies between 60 to 100 μm and for water and other liquids it varies between 200 to 500 μm. Know More
