 TAURUS EMERGÉ - High Pressure Hoses

The flexible hose lines are built from steel and elastomeric materials into a bonded construction. The main point of bonded construction is that the layers in the flexible hose wall are built individually, then combined into one unit by vulcanisation. Hose assemblies are manufactured either as a single bonded unit to specified lengths, where the couplings are an integral part of the hose or they can be mounted on the cured hose by swaging.

General Construction - High Pressure Hoses

  • 1. Stainless steel interlock stipwound tube
  • Function: protects the elastomeric lining from mechanical damage, prevents blistering in case of use with gas and decompression with vacuum service, supports the wall of flexible hose and facilitates pigging. The material can be AISI 304, 316L or 254 SMO quality stainless steel, depending on the conveyed medium.

  • 2. Elastomeric polymer lining
  • Function: Fluid barrier of the flexible line. Protects the hose construction from corrosive and abrasive effects of the conveyed medium. The thickness of lining depends upon the internal pressure, the inside diameter and the abrasiveness of the conveyed medium. The lining material is selected to withstand chemical and heat effects of crude oil, seawater, gases, hydraulic fluid or whatever substance is contained in the hose.

  • 3. Textile plies
  • Function: to distribute the forces of internal pressure

  • 4. Stiffening spiral (not shown in the figure)
  • Function: to protect the hose against collapse under axial pulling force and/or due to external pressure. Prevents kinking even in sharp bends.

  • 5. Elastomeric cushion plies
  • Function: to ensure adhesive bonding and interaction between different plies

  • 6. High strength steel cable reinforcements
  • Function: These are the most important load-bearing elements. They determine internal pressure resistance.

  • 7. Elastomeric cover
  • Function: to protect the flexible hose line from impact, abrasion, weather, seawater, oil, etc. On request, a fire rated cover can be applied.

  • 8. Outer stainless steel stipwound protection
  • Function: to protect the hose against external mechanical damage, material AISI 304
