Integral Pup Joint vs Welded Straight Pipe
| Feature | Integral Pup Joint | Welded Straight Pipe |
|---|---|---|
| Construction | Integral forged / machined body | Pipe body with welded end connections |
| Welded joints | No end weld in integral body | Yes |
| Typical use | Higher-duty flowline service | General pressure-line configurations |
| Available ends | Hammer union / project-specific | Union / flange / thread |
| Custom length | Available | Available |
| Weight | Depends on design | Depends on design |
| Repair approach | Replace / inspect complete assembly | Weld inspection may be required |
| Selection basis | Pressure, erosion, service, connection | Pressure, service, connection, fabrication requirement |
FIG 1502 Integral Pup Joint
FIG 1502 integral pup joints are commonly specified for high-pressure surface flowlines requiring a 15,000 psi class hammer-union connection in standard service.
Typical applications include:
Fracturing lines
Cementing lines
High-pressure pump discharge
Well testing
Manifold connections
Pressure-control flowlines
Standard and Custom Pup Joint Lengths
Pup joints can be supplied in standard or project-specific lengths according to the flowline layout.
Typical order descriptions may include:
2 in FIG 1502 × 2 ft
2 in FIG 1502 × 4 ft
3 in FIG 1502 × 6 ft
Custom length according to GA drawing
Overall length definition should be confirmed on the approved drawing before production.
