5.1    No. of Coil: 1(one)

5.2    No. of Pass/path: 14 (fourteen) passes.

5.3    No of Path: 5 paths

5.4:   Coil size: 4" (101.6mm) NB x 0.337" (8.55mm) wall thickness (Schedule 80)X 8.5 Mtrs long

5.5:   Header Pipe size: 8" NB, OD: 8.625", Schedule: 80

5.6:   Coil Material: Seamless pipe as per API-5L Gr. B, / ASTM   A106 Gr. B .

5.7    Coil Operating Pressure: Max:  105.46 kg/cm2 (1500 psig)
