Crossover Adapter – 3" FIG 1502 Male (Wing) x 2" FIG 1502 Female (Thread) w/ Inline Groove for Button Choke

The Crossover Adapter, 3" FIG 1502 Male (Wing) x 2" FIG 1502 Female (Thread) with an Inline Groove for Button Chokes, is a highly specialized, dual-purpose flowline component. Engineered to safely step down pipe diameter from a 3-inch large-bore line to standard 2-inch piping, this unit simultaneously acts as an inline flow-control device within a 15,000 PSI high-pressure piping system.

What sets this specific step-down adapter apart is its precision-machined internal bore, which features a dedicated inline groove (recess) designed to securely seat standard button chokes (orifice beans). By incorporating this groove directly into the crossover body, field operators can insert a choke bean to restrict flow rates and manage pressure drops without the need for installing a separate, bulky positive choke valve body. This provides immediate flow control while seamlessly transitioning from a 3-inch male (wing) manifold connection into a 2-inch female (thread/sub) distribution line.

Because both ends utilize the robust FIG 1502 profile, the entire crossover assembly safely maintains a full 15,000 PSI cold working pressure rating, even when subjected to the extreme turbulence and abrasive wear caused by the flow restriction of the internal choke.

Features & Benefits

• Inline Button Choke Groove: Precision-machined internal recess allows for the direct installation of a button choke/orifice bean, turning the adapter into a compact flow-control device.

• Seamless Step-Down Transition: Safely steps down pipe diameter from a 3-inch large-bore line to a standard 2-inch line, reducing the need for multiple swages.

• Reduced Rig-Up Footprint: Combines size-reduction and flow restriction into a single, integral fitting, saving crucial space and weight on complex manifolds.

• Full 15K CWP Capacity: Maintains an uninterrupted high-pressure rating of 15,000 PSI across the entire assembly, built to withstand extreme turbulence and pressure drops.

• Heavy-Duty Forged Construction: Manufactured from high-strength alloy steel to endure severe shock loads, vibration, and the high-velocity abrasive wear associated with choked fluid flow.

Specifications & Technical Details

Applications

This specialized step-down crossover is widely used in high-pressure surface operations requiring immediate flow restriction at the point of a size transition. Typical applications include high-velocity flowback operations, well testing packages, custom choke and kill manifolds, blowdown lines, and frac iron rig-ups where operators must manage pressure drops while feeding 3-inch lines into 2-inch 15,000 PSI distribution networks.

Quality Assurance

All our crossover adapters are manufactured from premium forged alloy steel and subjected to strict quality control processes. Each fitting undergoes rigorous dimensional inspection (including precise tolerance checks on the choke groove) and hydrostatic pressure testing prior to shipment to ensure absolute safety, shell integrity, and seal performance under maximum working loads. Full material traceability is available to guarantee compliance with API guidelines.
