Delivery Tubing/Lines: Temperature Range -20°C to +80°C

Component Specifications

Definition

Delivery tubing/lines are specialized high-pressure conduits designed to transport abrasive slurry mixtures from the mixing unit to the cutting head in abrasive waterjet systems. These components must withstand extreme pressures (typically 60,000-90,000 psi), resist abrasive wear, and maintain structural integrity while handling abrasive particles suspended in water. They feature reinforced construction with multiple layers including inner wear-resistant liners, high-strength reinforcement layers, and protective outer jackets.

Working Principle

Operates on fluid dynamics principles where pressurized abrasive slurry flows through the tubing system. The tubing contains and directs the high-velocity abrasive mixture while withstanding internal pressure through reinforced wall construction. Specialized fittings and connections maintain pressure integrity throughout the delivery path from pump to cutting nozzle.

Materials

Multi-layer construction: Inner liner - polyurethane or specialized polymers (Shore D 70-85), Reinforcement layer - high-tensile steel wire braiding or Kevlar fibers, Outer jacket - abrasion-resistant thermoplastic or rubber compound. End fittings typically stainless steel (316L) or specialized alloys.

Improper connection causing leakage
Fatigue failure from pressure cycling

FMEA Triads

Trigger: Abrasive particle erosion of inner liner
Failure: Pressure loss, reduced cutting performance, eventual rupture
Mitigation: Regular inspection, pressure testing, use of wear-resistant liner materials, proper abrasive filtration

Trigger: Improper installation with excessive bending
Failure: Reduced flow, increased pressure drop, premature failure
Mitigation: Follow minimum bend radius specifications, use proper support brackets, ensure straight runs before fittings

Frequently Asked Questions

What is the typical service life of abrasive slurry delivery tubing?

Service life varies from 500-2,000 hours depending on operating pressure, abrasive type, and maintenance practices. Regular inspection for wear and pressure testing is recommended every 200 operating hours.

Can different abrasive materials affect tubing performance?

Yes, garnet abrasives typically cause less wear than aluminum oxide or silicon carbide. Harder abrasives reduce tubing life by 30-50% compared to standard garnet abrasives.
