Supply Line: Temperature Range -40°C to 200°C, Diameter 6-50 mm

Component Specifications

Definition

A supply line is a precisely engineered piping component designed to convey fluids (liquids or gases) within industrial machinery. It serves as the primary conduit connecting fluid reservoirs, pumps, valves, and actuators in fluid distribution systems. These lines maintain specified flow rates, pressure levels, and temperature ranges while minimizing pressure drops, contamination risks, and energy losses. They are engineered with specific diameters, wall thicknesses, and connection types to match system requirements.

Working Principle

Supply lines operate on fluid dynamics principles where pressure differentials drive fluid movement through the conduit. The line's internal diameter, surface smoothness, and material properties determine flow characteristics, pressure losses, and compatibility with conveyed media. Proper installation ensures leak-free connections and maintains system integrity under operational stresses including vibration, thermal expansion, and pressure fluctuations.

Materials

Stainless steel (AISI 304/316), carbon steel, copper alloys, thermoplastics (PVC, PTFE, polyethylene), reinforced rubber hoses with steel braiding. Material selection depends on fluid compatibility, pressure rating (typically 10-300 bar), temperature range (-40°C to 200°C), and corrosion resistance requirements.

Frequently Asked Questions

What factors determine supply line material selection?

Material selection depends on fluid compatibility (chemical resistance), operating pressure and temperature, corrosion requirements, hygiene standards (for food/pharma), flexibility needs, and cost considerations.

How often should supply lines be inspected?

Visual inspections should occur monthly, with comprehensive testing every 6-12 months depending on service conditions. High-pressure or critical applications may require more frequent monitoring.

Can different material supply lines be connected?

Yes, but requires proper transition fittings and consideration of galvanic corrosion, thermal expansion differences, and pressure rating compatibility.
