Pipe & Fabricated Spool

This can be used to manufacture and fabricate a variety of sizes and material kinds, including solid nickel-based alloy fabrications and Clad Inc625/825 product, to meet the rigorous client requirements.
When we are operating at full capacity, we can designate 28 pipe fitters, 64 welders, and 8 NDE personnel to support the spool fabrication activities. This will yield a daily productivity of roughly 600 inch dia (60 joints of 10″ dimension, 12.7 + 3 mm Clad wall thickness).
To enable Sparrows to provide a comprehensive supply to our customers, our fabrication capacity gives a complete synergy to the other core product types within the company.


Sparrow LLC is your one-stop resource for all your pipe spool fabricating needs. It includes plate material procurements as per the code requirement.

Sparrow LLCowns a mechani-cal fabrication support eqipments supply with all required equipment for pipe cutting, rolling and welding.

Pipe spools are fabricated from a number of raw pipes and pipe fittings (e.g. elbows, flanges, tees, etc.) in our fabrication shop. Raw pipes are cut to the required sizes and moved with pipe fittings to a fitting table, where the components are fitted together. The resulting sub-assembly is transferred to the welding operation before it comes back to the fitting table and gets fitted with other spool components.
Spool fitting and welding can be grouped into two types:

  1. Roll fitting and welding
  2. Position fitting and 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.

In such case, the fitter or the welder has to move around the main pipe run to accomplish fitting or welding. As a result, position fitting and welding usually takes more time to finish than roll fitting and welding. To minimize the number of position fittings and welding is one of the goals of pipe spool fabrication sequencing.

Cost Savings
Quality of the work is easier to manage & maintained in a controlled environment. High accuracies 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 a 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 less fabrication / assembly time, thereby avoiding time & cost overruns.
Prefabricated Spools will entail no or little investments in fabrication & testing equipment by users. Radiography, PMI, MPI, Ultrasonic tests, Hydro-tests etc. can be performed better & effectively in a controlled environment
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 a controlled environment results 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 & 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 & other contaminants that are unacceptable according to international standards.

Why pre-fabricate the Pipe Spools?

It is necessary to pre-fabricate the Pipe Spool. Pipe Spools are pre-fabricated to

  1. Enhance the quality of the assembly.
  2. Reduce field installation costs.
  3. Provides less workforce for the fabrication of spools on site.
  4. Minimize the production delays because the fabrication process is weather independent.
  5. Obtain better control of welding parameters, so fabrication must be done in the controlled environments.
  6. Minimize the investment in production and testing equipment by the users.
  7. Avoid unnecessary time delays.
  8. Get specified and accurate dimensions specified by the client.
  9. Obtain lesser assembly time and avoid rework on site.
  10. Get accurate fitting to be used on the site.
