Field Selection Guide: FIG1502 Pressure Test Accessories and Manifold Crossovers
In high-pressure treating line configurations across North American basins such as the Permian and Bakken, maintaining system integrity during mobile rig hookups is critical. Field engineering crews rely on specialized flowline components to perform pre-operational hydrostatic testing, transition between API flanged valves, and execute smooth line size reductions without compromising pressure ratings.
Utilizing standardized Flowline FIG1502 Fittings ensures complete dimensional compatibility and secure mechanical makeup across active well testing and fracturing spreads.

1. Hydrostatic Testing Protocols with Test Plugs and Caps
Before introducing wellbore fluids into surface treating lines, crew members must isolate segments to conduct pressure tests:
- 3” 1502 Thread Test Plugs: Thread directly into female union ends to cap off line sections, featuring a 1/2" NPTF port for pressure gauge attachment or bleed-off lines.
- 3” 1502 Wing Test Caps: Designed to pair with male union sub ends using standard wing nuts, providing secure temporary closure during line verification.

2. Bridging Flanged Equipment and Hammer Union Lines
Manifold designs often require connecting API 6A flanged wellhead components to flexible hammer union spreads:
- Flange Crossovers: The 4-1/16” 10M Flange x 3” 1502 Wing X-over allows direct bolting to master valves or choke manifolds while providing a standard wing union outlet.
- Reducing Crossovers: 3” to 2” step-down union adaptors manage flow velocity changes between main headers and auxiliary treating lines.

Procurement Checklist for Oilfield Flowline Accessories:
- Confirm thread profiles and sizing match existing rig inventory (FIG1502 standards).
- Verify forged alloy steel construction and NDT inspection compliance.
- Ensure complete material test reports (MTRs) are provided with delivery batches.
