Transport Tubing: temperature_range -40°C to 200°C

Component Specifications

Definition

A precision-engineered tubular component designed to transport air samples from collection points to aspirated detectors in industrial sampling systems. It maintains sample integrity by preventing contamination, adsorption, or chemical reactions during transit, ensuring accurate detection of gases, particulates, or vapors in manufacturing environments.

Working Principle

Operates on pneumatic transport principles, using pressure differentials or vacuum systems to move air samples through the tubing. The smooth inner surface minimizes turbulence and pressure drop, while the material composition prevents sample degradation. Proper diameter and length are calculated to maintain flow rates that match detector sampling requirements.

Materials

Typically made from chemically inert materials: PTFE (Teflon) for corrosive gases, stainless steel 316L for high-temperature applications, silicone for flexibility, or FEP for transparency. Material selection depends on chemical compatibility, temperature range (-40°C to 200°C), and pressure requirements (vacuum to 10 bar).

Frequently Asked Questions

How often should transport tubing be replaced in sampling systems?

Replacement depends on usage and material: PTFE tubes last 2-5 years with regular maintenance, while silicone may need annual replacement. Inspect quarterly for cracks, discoloration, or contamination.

Can different tubing materials affect detection accuracy?

Yes. Material adsorption can retain target compounds. PTFE has low adsorption for most gases, while some plastics may absorb VOCs. Always match tubing material to the sampled substances.
