Well Service 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 well service applications, such as well test, onshore and offshore well stimulation and burner boom hoses to meet the needs of both onshore & offshore service providers.

Sustainable Benefits

Low environmental risk: The bonded couplings of the well service hoses are designed to be the strongest part of the assembly, resulting in exceptionally high safety & reliability. Continental onshore well stimulation hoses significantly decrease the risk of fluid spills compared to the traditional steel irons, swivels and elbows.

Long service life: Continental onshore well stimulation hoses last considerably longer than the traditional steel piping in the erosive application, hence they are a more sustainable choice: minimizing needs for replacement. Additionally, they extends service life of adjacent equipment, piping and valves due to reduced turbulence in the flow.

Applications

Well test
Offshore well stimulation, intervention & acidizing
Onshore well stimulation
Burner & flare boom

General construction of a High Pressure Well Service 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.

General Construction of a Well Service Hose

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 well test hoses.

Polymer lining
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 well effluents, well stimulation fluid, acids or whatever substance is conveyed through the hose.

Textile plies
To distribute the forces of internal pressure.

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.

Elastomeric cushion plies
To ensure adhesive bonding between different plies.

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.

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

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

UV resistant elastomeric cover
Protect the flexible hose line from impact, abrasion, weather, seawater, oil, etc.
Outer stainless steel stripwound protection
Optional layer, protect the hose against external mechanical damage, material AISI 316L. For different types of available external protection, contact your Continental representative.
