3" 15,000 PSI Fig 1502 Style 10 x 50 Steel Hose Loop (12 FT) – Oil & Gas Flowline

The 3" Figure 1502 Steel Hose Loop (Style 10 x Style 50, 12-Foot Length) is a high-capacity, articulating flowline assembly engineered for maximum flexibility and reach in extreme-pressure environments. Rated for a Cold Working Pressure (CWP) of 15,000 PSI, this heavy-duty assembly—widely known as a Chiksan loop—is an essential component for high-volume hydraulic fracturing, cementing, acidizing, and well-testing operations where 3-inch iron is required for increased flow rates.

Manufactured from high-strength forged alloy steel, this extended 12-foot steel hose loop utilizes precision-engineered swivel joints to absorb severe vibration, thermal expansion, and complex rig-up misalignments. The configuration of a Style 10 (three planes of rotation) and a Style 50 (two planes of rotation) swivel joint allows the loop to fold compactly for transportation and extend fully to 12 feet during field setup. This extra length is particularly advantageous for routing lines around obstacles and bridging wider gaps between manifolds and pump trucks. The sweep-radius elbows are designed to optimize fluid dynamics, significantly reducing internal turbulence, pressure drops, and erosion when pumping abrasive slurries or high-velocity hydrocarbons.

Equipped with industry-standard 3" Figure 1502 male (wing nut) and female (threaded hub) ends, this 12-foot loop ensures rapid, blowout-proof makeup and full interchangeability with existing flowline iron, delivering superior safety and performance in demanding upstream service.

Features & Benefits

• 15,000 PSI CWP Rating: Built to handle the extreme pressures of modern stimulation and high-volume well-servicing.

• 12-Foot Maximum Reach: Offers extended length for versatile flowline routing while remaining foldable for ease of transport.

• Style 10 x 50 Articulation: Five total planes of rotation provide exceptional flexibility, vibration dampening, and compensation for dynamic movement.

• Standard 1502 Connections: 3" Hammer union ends provide fast, secure, and fully interchangeable rig-ups.

• Sweep-Radius Elbows: Precision-cast elbows minimize flow restriction and protect against internal abrasive wear.

• Forged Alloy Steel Construction: Delivers high structural integrity to resist mechanical shock, pulsation, and fatigue.

Specifications & Technical Details

Applications

This 12-foot, 15,000 PSI steel hose loop is designed for high-pressure, high-volume fluid transfer. Typical applications include large-scale frac iron arrays, high-pressure cementing lines, acidizing pump discharge manifolds, and temporary flowlines for well testing where flexible, long-reach iron is necessary to navigate field layouts.

Quality Assurance

Each steel hose loop assembly is manufactured under strict quality control standards. Swivel joints and piping segments undergo rigorous dimensional inspection, non-destructive examination (NDE), and high-pressure hydrostatic testing to ensure reliable sealing and structural performance under maximum field loads.
