Large-Scale Quartz Heat Exchange Tubes | Chemical-Resistant Solutions for Harsh Environments

Discover how our jumbo-sized quartz heat exchange tubes, expertly welded for leak-proof performance, solve corrosion challenges in chemical plants. Custom designs with pH resistance up to 98% H2SO4.

1. Why Quartz Outperforms Metal in Corrosive Heat Exchange

Quartz tubes (SiO2≥99.99%) are revolutionizing chemical heat exchange systems by offering:

Unmatched Corrosion Resistance:

Withstands aggressive media including:

▶ Acids: 98% sulfuric acid (200°C), 37% hydrochloride acid

▶ Alkali: 40% NaOH solutions

▶ Solvents: Chlorinated hydrocarbons, ketones

Zero Metal Contamination: Ideal for pharmaceutical & semiconductor-grade processes.

Thermal Stability: Operates at -100°C to 1,200°C without deformation.

2. Overcoming the“Big Size Challenge”in Quartz Engineering

While most suppliers struggle with tubes over 200mm diameter, our proprietary solutions ensure reliability:

Precision Welding Expertise

Seamless Joints: Our master welders achieve ≤0.01mm porosity using:

▶ Oxygen-hydrogen flame fusion

▶ Post-weld annealing (1100°C, 12hrs)

Structural Reinforcement

Patent-pending hexagonal support lattice prevents sagging in horizontal installations.

5. FAQs for Chemical Engineers

Q: Can quartz tubes handle rapid temperature cycling?

A: Yes. Our tubes survive 300°C → 25°C quenches (per ASTM C1468-19), thanks to ultra-low CTE (5.5×10⁻⁷/°C).

Q: How to remove polymer deposits?

A: Use 3:1 HNO3/HF mixture at 60°C (compatible with quartz, unlike alkaline cleaners).
