Pipe spool fabrication process
To fabricate a spool below are the methods used by pipe spool manufacturers
| Method 1 | Roll welding/ Roll fitting and welding | |
| Method 2 | Position welding/ Permanent position fitting and welding |
No room for mistakes so here we enlisted only specialized and most experienced pipe spool fabrication companies, view list of required testing
Material wise suitable welding methods
| Can be weld | Not able to weld | |
|---|---|---|
| FCAW | Carbon steels, cast iron, nickel based alloys | Auminum |
| Stick welding | Carbon steels, nickel based alloys, Chrome, ss, even Aluminum but not the best Best to weld thicker metals |
Thin sheet metals |
| Tig welding | Best for steel & aluminium for precise & small welds |

Minimum pipe spool piece between welds
Code & standard for Pup/ short piece of pipe or pipe spool piece between welds
- Choose the length of pipe spool minimum of 2 inch or 4 times of wall thickness to keep butt weld little far to avoid overlapping weld
- As per Australian Standard AS 4458 – distance between the edge of 2 butt welds should be minimum 30 mm or 4 times pipe wall thickness
