Certification & Quality Assurance
Manufactured and tested in strict accordance with API Spec 16C, this choke hose ensures the highest levels of safety and durability in critical drilling applications. To guarantee performance and reliability, each hose assembly is hydrostatically tested at 7,500 psi for 60 minutes. A comprehensive pressure test graph, an official test certificate, and a letter of conformance are issued with every hose to provide full traceability and compliance.
Primary Applications
Specifically designed for high-pressure integrity and flexibility, this hose is ideal for use as a flexible connection between the marine riser and manifold, or around the ball joint of offshore drilling rigs. It is engineered to handle the extreme dynamic stresses and pressures of choke and kill line services.
Construction & Materials
- Tube: Manufactured from a modified Nitrile compound, the tube provides exceptional resistance to abrasion, corrosion, and petroleum-based fluids, ensuring long service life.
- Reinforcement: Built for extreme pressure containment, the hose features multiple layers of high-tensile textile fabric and steel cable. A specialized layer of intermediate rubber is placed between the cable layers to enhance flexibility, prevent friction, and maintain structural integrity under pressure.
- Cover: The outer cover is constructed from a fire-resistant rubber compound and is armored with a stainless steel jacket. This rugged exterior protects against severe working conditions, including abrasion, corrosion, cutting, gouging, oil, and harsh weather.
- Couplings & End Connections: Fitted with precision, factory-swaged couplings to ensure a permanent, leak-proof bond. A full range of end connections is available to meet specific rig requirements, including hammer unions, flanges, hubs, and various male thread configurations.
Summary
The API 16C Choke Hose combines robust fire-resistant and armored protection with certified high-pressure performance. It is the reliable choice for demanding offshore drilling environments where safety and durability are paramount.
