High collapse resistant thermoplastic hose

21st September 2015

Designed for subsea oil and gas applications, power management company Eaton has introduced the Synflex 33CH-08 high collapse resistant thermoplastic hose.

The new hose features a liner tube made of polyvinylidene fluoride (PVDF), which helps handle fluids with higher concentrations of acid and lowers permeability with methanol and other similar fluids. Typical applications for the 33CH-08 include for instance hydraulic flying leads, Installation/Intervention

Work Over Control (IWOC) umbilical hoses, high flow rate applications and methanol injection.

“The 33CH-08 is the latest addition to Eaton's Synflex line of subsea hose products, built to meet the evolving needs of the oil and gas industry," says Johannes Kammerlohr, product manager, Eaton. “In handling fluids with high concentrations of acid, and significantly reducing permeation of methanol-type fluids, this hose product will help end users achieve their production goals both safely and sustainably.”

Comprising a stainless steel carcass, which is reinforced with two braids of Kevlar* aramid fibre, the 33CH-08 hose is jacketed with blue polyurethane. The blue colouring makes the hose easily identifiable underwater compared to conventional subsea hoses, which usually have black outer jackets, even at significant depths. The jacket is pin-pricked in accordance with American Petroleum Institute (API) specification 17E.

The new hose is rated for 345 bar (5000 psi) working pressure (WP), with a full ISO 13628-5 rating, including a 4-to-1 burst to WP ratio and more than 200,000 test cycles at 460 bar (6650 psi). The 33CH-08 is expected for use at temperatures from -40°C to +70°C, and is lightweight at only 23 kg per 30 m (50.1 pounds per 100 feet). It is currently available in continuous lengths of up to 3km (10,000 feet).
