Tubing/Connections: Temperature Range -40°C to 200°C

Component Specifications

Definition

Tubing/connections in pumping systems refer to the network of pipes, hoses, fittings, and couplings that transport fluids (liquids or gases) between system components. They maintain pressure, prevent leaks, and ensure efficient fluid flow in industrial applications.

Working Principle

Tubing provides a sealed conduit for fluid transport, while connections (fittings, couplings) join tubing sections or attach to equipment. They rely on mechanical sealing (compression, threaded, flanged) or welding to maintain pressure integrity and prevent fluid loss.

Materials

Stainless steel (AISI 304/316), carbon steel, PVC, PTFE, nylon, rubber (EPDM, nitrile), brass, aluminum; selected based on fluid compatibility, pressure, temperature, and corrosion resistance.

Technical Parameters

Frequently Asked Questions

What are common failure modes in tubing/connections?

Leaks due to improper sealing, corrosion, fatigue cracks, or overpressure; reduced flow from blockages or kinks; material degradation from chemical exposure.

How to select tubing material for a pumping system?

Consider fluid type (corrosive, abrasive), pressure/temperature requirements, environmental conditions (outdoor, chemical exposure), and compliance with industry standards (e.g., food-grade for beverage manufacturing).
