Production Flexible Lines

Continental is a global leader in the design, manufacture and supply of bonded flexible lines. For over 50 years, we’ve led the industry in metallic reinforced bonded elastomer hoses—proudly becoming the first to earn certification under the API 17K standard. We have since built up a broad portfolio of hoses for a variety of production applications, such as topside jumpers, subsea jumpers, risers, flowlines and tie-ins to meet the needs of major oil & gas producers and engineering companies.

Sustainable Benefits

Low environmental risk: The bonded production flexible lines are designed and manufactured according to the very stringent API 17K standard, resulting in exceptionally high safety & reliability.

Customized for the application: By engineering the production flexible lines for the actual application, Continental ensures lower material and manufacturing carbon footprint and lower overall investment costs.

Long service life: Continental production flexible lines are designed for over 20 years of service life and hence are a sustainable choice: minimizing needs for replacement.

General construction of a Bonded Production Flexible Line

The flexible lines are a bonded construction comprising steel and elastomeric materials. The principal characteristic of bonded construction is the build-up of individual layers in the flexible hose wall which are then combined into one unit through vulcanisation. Hose assemblies are manufactured as a single bonded unit to specified lengths where the couplings are a chemically bonded integral part of the hose.

  1. Stainless steel interlock stripwound tube
    Protects the polymer lining from mechanical damage, prevents blistering in case of high pressure gas service and decompression with vacuum service, supports the wall of the flexible hose and facilitates pigging. The material can be AISI 316L or 254 SMO grade stainless steel, depending on the conveyed medium.
  2. Polymer lining
    Fluid barrier of the flexible line. Protects the hose construction from corrosive and abrasive effects of the conveyed medium. The thickness of lining depends on the internal pressure, the inside diameter and the conveyed medium. The lining material is selected to withstand chemical and heat effects of crude oil, seawater, gases, hydraulic fluid and any other substance that is conveyed through the hose.
  3. Textile plies
    To distribute the forces of internal pressure.
  4. Stiffening spiral (not shown in the picture)
    To protect the hose against collapse under axial pulling force and/or as a result of external pressure. Prevents kinking even in sharp bends.
  5. Elastomeric cushion plies
    To ensure adhesive bonding between different plies.

6. High strength steel cable reinforcements
These are the most important load-bearing elements, they determine internal pressure resistance. The cables are either zinc or brass coated to provide exceptional corrosion resistance.

7. Gas leading plies
To allow diffused gases to migrate to venting points.

8. Fire resistant plies
Protects the hose in case of exposure to flame at 704°C (1300°F) for at least 30 minutes.

9. UV resistant elastomeric cover
Protect the flexible hose line from impact, abrasion, weather, seawater, oil, etc.

10. Outer stainless steel stripwound protection
Protect the hose against external mechanical damage, material AISI 316L.
