3" 15,000 PSI Fig 1502 Choke Bonnet – High-Pressure Valve Component

The 3" Figure 1502 Choke Bonnet is a critical, heavy-duty pressure-containing closure engineered to seal the top of a high-pressure choke valve body. Rated for a Cold Working Pressure (CWP) of 15,000 PSI, this structural component serves as the robust housing for the internal choke mechanisms, including the stem, packing, and seal piston. It is an essential part of adjustable and positive choke assemblies used in severe-service well testing, hydraulic fracturing, and flowback operations.

Manufactured from premium forged alloy steel, the choke bonnet is designed to withstand extreme internal pressures, severe mechanical vibration, and the erosive forces of abrasive drilling muds and frac fluids. The interior is precision-machined to exacting tolerances to provide a flawless sealing surface for the stem packing, ensuring a blowout-proof barrier that prevents hazardous high-pressure fluids and gases from escaping into the atmosphere. The bonnet is typically secured to the choke body using a heavy-duty hammer union nut, allowing for rapid field disassembly and maintenance.

Built for uncompromising safety and long-term durability, the 3" 1502 Choke Bonnet ensures the structural integrity of the entire valve assembly, facilitating smooth and precise flow regulation in the most demanding upstream environments.

Features & Benefits

• Precision Machined Internals: Ensures perfect alignment of the choke stem and provides a flawless sealing surface for high-pressure packing sets.

• Standard Interchangeability: Fully compatible with industry-standard 3" Figure 1502 adjustable and positive choke valve bodies.

• Rapid Field Maintenance: Designed to integrate seamlessly with hammer union bonnet nuts for quick access to internal valve components.

• Blowout-Proof Design: Robust architecture prevents structural failure and atmospheric leaks during high-pressure well-control events.

Specifications & Technical Details

Applications

This 3" Figure 1502 choke bonnet is primarily used to house the internal components and seal the body of high-pressure choke valves. Typical applications include choke and kill manifolds on drilling rigs, high-pressure well-testing headers, frac flowback skids, and severe-service production manifolds where precise pressure regulation and absolute fluid containment are required.

Quality Assurance

Each choke bonnet is manufactured under rigorous quality control standards. The raw forgings undergo non-destructive examination (NDE) to detect any internal flaws, while the machined threads and packing bores are subjected to strict dimensional inspections to guarantee perfect fitment, smooth operation, and reliable performance under 15,000 PSI field loads.
