Flange Adapter – 1-13/16" 15M x 3" FIG 1502 Male (Wing) | 15K CWP

The Flange Adapter, 1-13/16" 15M x 3" FIG 1502 Male (Wing), is an elite high-integrity crossover component engineered to bridge a permanent or semi-permanent bolted API 6A connection directly with a large-bore temporary hammer union treating line under extreme pressure. Engineered for seamless integration into 15,000 PSI systems, this integral forged adapter enables operators to safely and efficiently transition fluid streams from standard wellhead equipment, blowout preventers (BOPs), and frac trees directly into high-volume 3-inch surface flowlines or temporary iron packages without compromising structural integrity.

In critical upstream environments, connecting disparate iron lines under massive pressure requirements demands absolute metallurgical precision. Both the 15M API flange and the 3-inch Figure 1502 hammer union ends are individually engineered to support an intense 15,000 PSI continuous cold working pressure (15K CWP). This unified rating removes flowline pressure bottlenecks and ensures the complete adapter assembly provides a reliable, high-pressure boundary capable of withstanding the severe vibrational energy, pressure cycles, and massive erosive velocities common to hydraulic fracturing, high-rate flowback, and large-volume well testing operations.

This component features a one-piece integral forged layout that completely eliminates welded joints and structural weak points. Side A is a 1-13/16" 15M flanged profile conforming to API 6A Type 6BX specifications, complete with a precision-machined Ring-Type Joint (RTJ) groove engineered for a BX-151 metal ring gasket to deliver a tight metal-to-metal barrier. Side B features an integral 3-inch FIG 1502 male wing profile complete with a heavy-duty wingnut, allowing for rapid, adapter-free hammer-up installation directly into a corresponding 3-inch female (threaded sub) connection point in the field.

Features & Benefits

• Full 15K CWP Capacity: Both connection ends are rated for an extreme 15,000 PSI continuous cold working pressure, eliminating de-ratings and matching the full pressure capabilities of the high-pressure system.

• Large-Bore Transition: Seamlessly bridges a 1-13/16" flanged connection with a 3-inch flowline, accommodating higher volumetric flow rates downstream without requiring multiple sizing subs.

• Integral Male Wing Profile: Side B comes equipped with an integral 3-inch 1502 male hub and a heavy-duty wingnut, allowing fast, secure connections to female large-bore iron configurations.

• Integral Forged Engineering: Machined entirely from a single solid block of high-strength alloy steel, maximizing structural rigidity and resistance to cyclical stress fatigue while eliminating potential weld-line leaks.

• Precision Metal-to-Metal Sealing: The API flanged end contains a precisely machined ring groove optimized for high-pressure BX ring gaskets, forming a tight shell barrier that tightens under internal force.

Specifications & Technical Details

Applications

This high-pressure 1-13/16" 15M x 3" 1502 male wing flange adapter is an indispensable asset for large-bore upstream surface layout configurations where severe pressure lines must be routed dynamically. Typical applications include adapting 15,000 PSI wellhead gate valves and frac tree outlets to high-capacity 3-inch temporary iron packages, rigging up extreme-pressure choke and kill manifolds, executing large-volume flowback tie-ins, and connecting high-rate pumps to well control elements.

Quality Assurance

All our high-pressure integral crossover adapters are forged from premium clean alloy steel and subjected to meticulous quality control verification. The adapter bodies undergo non-destructive testing (NDT), including magnetic particle and ultrasonic inspections, alongside hydrostatic shell pressure tests to verify structural integrity under peak working stresses. Flange faces and union threads are checked via strict precision gauges to ensure long-term, leak-free sealing field compliance. Full material test reports (MTRs) are available upon request.
