Choke and Kill Lines

Coflex flexible hoses are for drilling and service both onshore and offshore in applications as choke and kill lines. Choke and kill lines are essential to control the well control equipment. Coflex flexible hoses are specifically designed to handle the high pressures and flowrates this use requires.

All coflex hoses are designed in accordance with API 16C, composed of inner core, double cross wireline layer, heat-insulation layer, fire-resistance layer, buffering and sealing layer, and stainless steel jacket.

High pressure flexible hoses are required in combination with flexibility and reliability in high pressure resistance, thermal insulation, anti-flaming, fire resistance and high abrasion resistance inner wall.
