Latest high pressure hoses for subsea oil and gas applications

Oilfield Technology,

Power management company Eaton has introduced the Synflex® 3395-32 and 3394-32 Thermoplastic Hoses, designed to help increase uptime, safety and reliability for subsea oil and gas applications.

The new high pressure hoses are a market exclusive for 2 in. hoses reinforced with Kevlar® to withstand the demanding oil and gas industry in a lightweight package.

Lighter, flexible and buoyant for oil and gas operations 

By reinforcing each hose with Kevlar instead of steel wire, this latest Synflex product development is considerably lighter, more flexible and more buoyant than competitive steel wire reinforced hoses. At less than 1.4 lbs/ft in air, the 3395-32 weighs in 3 lbs/ft lighter than steel wire hoses, considerable weight savings when factoring in the thousands of feet required for subsea applications. The weight reduction removes the need for specialty equipment to deploy down and reel up the hose, while making it easier and safer for workers to move or carry.

Both the 3395-32 and 3394-32 hoses are built with P40 TL grade nylon core tubes, with two braids of Kevlar aramid fiber reinforcement and jacketed with black polyurethane, which is pin-pricked in accordance with API 17E. The Guardian™ abrasion protection and patent-pending detection overlay is separated from the base hose by a Mylar® film with a linear monofilament to permit gas flow between the hose and the overlay. 

The 3395-32 hose is rated for 5000 psi working pressure and a 3-to-1 burst to WP ratio, while the 3394-32 hose is rated for 3750 psi working pressuring with a full API 17E rating and 4-to-1 burst to WP ratio. Both products exceed 200 000 impulse test cycles and can withstand operating temperatures ranging from -40 to 72 °C.

The hoses are currently available in continuous lengths up to 2500 ft.
