Tube Section: Diameter Range 25-200 mm, Wall Thickness 1.5-6 mm

Component Specifications

Definition

A precision-engineered cylindrical component that forms part of a product heating and holding tube assembly, specifically designed to maintain consistent temperature control during product processing. It typically features controlled wall thickness, smooth internal surfaces to prevent product adhesion, and optimized thermal conductivity properties for efficient heat transfer.

Working Principle

Operates on conductive and convective heat transfer principles where thermal energy flows from the heating medium (typically steam, hot water, or electrical elements) through the tube wall to the product flowing inside. The design ensures uniform temperature distribution along the length while maintaining product integrity through controlled residence time.

Materials

Food-grade stainless steel (AISI 304, 316L), titanium alloys for corrosive applications, or specialized nickel alloys for high-temperature operations. Surface finish: Ra ≤ 0.8 μm internally, electropolished for cleanability.

Frequently Asked Questions

What are the key considerations when selecting a tube section for heating applications?

Material compatibility with product, thermal conductivity requirements, pressure and temperature ratings, surface finish for cleanability, and compliance with food safety standards.

How does wall thickness affect heating performance?

Thinner walls improve heat transfer efficiency but reduce pressure capacity. Optimal thickness balances thermal conductivity with structural integrity and pressure requirements.
