End Hose Component – Chemical Manufacturing

Component Specifications

Definition

A flexible, reinforced hose component installed at the terminal end of a delivery pipeline system, designed to facilitate the final transfer of liquids, gases, or semi-solids from the main pipeline to specific discharge points, tanks, or processing equipment. It accommodates movement, vibration, and misalignment while maintaining a secure, leak-resistant connection under operational pressures.

Working Principle

Operates by providing a flexible conduit that maintains fluid continuity between the rigid pipeline and the discharge point. It absorbs mechanical stresses (vibration, thermal expansion, movement) through its flexible construction, while internal reinforcement layers contain pressure and prevent deformation. The hose typically connects via standardized fittings (e.g., camlock, flange, quick-connect) to ensure secure attachment and easy replacement.

Materials

Typically constructed with an inner tube of chemical-resistant synthetic rubber (e.g., EPDM, NBR, FKM) or thermoplastic (e.g., PVC, polyurethane), reinforced with multiple layers of high-tensile textile braid or steel wire braid, and an outer cover of abrasion-resistant synthetic rubber or thermoplastic. Materials are selected based on fluid compatibility, temperature range (-40°C to +120°C), pressure rating, and environmental conditions.

Technical Parameters

Length 0.5 m to 3 m standard
Bend Radius 3x to 5x inner diameter
Reinforcement Textile braid (medium pressure) or steel wire braid (high pressure)
Inner Diameter 25 mm to 150 mm
Pressure Rating 10 bar to 25 bar
Temperature Range -30°C to +100°C

Standards

ISO 1402, ISO 5771, DIN 20066, DIN 20023

Frequently Asked Questions

What is the main function of an end hose in a delivery pipeline?

It provides a flexible connection at the pipeline's discharge point, allowing for movement absorption, easy alignment with receiving equipment, and secure transfer of fluids while minimizing stress on rigid pipeline sections.

How do I select the right end hose material?

Choose based on the fluid type (check chemical compatibility charts), operating temperature, pressure requirements, and environmental factors (e.g., UV exposure, abrasion). Common materials include EPDM for general purposes, NBR for oils, and FKM for aggressive chemicals.

What maintenance does an end hose require?

Regularly inspect for cracks, bulges, abrasion, or leaks; ensure fittings are tight and undamaged; clean internally if used with different fluids; and replace according to manufacturer lifespan recommendations or at signs of wear.
