Drilling Hoses

Continental is a global leader in the design, manufacture and supply of high pressure hoses. We have over 50 years of experience in metallic reinforced bonded elastomer hoses and has been the first company to obtain certification for all three governing industry standards: API 7K, 16C and 17K standard. We have since built up a broad portfolio for a variety of drilling applications, such as flexible choke & kill Lines, rotary & vibrator hoses, managed pressure drilling hoses to meet the needs of both onshore & offshore drillers and distributors.

Sustainable Benefits

Low environmental risk:The bonded couplings of the drilling hoses are designed to be the strongest part of the assembly, resulting in exceptionally high safety & reliability compared to the crimped or swaged couplings.

Customized for the application:Continental designed and tested hoses for each drilling application, ensuring lower material and manufacturing carbon footprint.
Long service life:Bonded Continental drilling hoses are designed for a long service life and hence are a sustainable choice: minimizing needs for replacement.

General construction of a High Pressure Drilling Hose

The high pressure hoses 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. This layer is optional and present only for rough bore hoses, such as for flexible choke & kill lines with TauroFlon™ liner.

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 drilling mud, well effluents, cement slurry, hydraulic fluid or whatever substance 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

Optional layer, 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.
