PTFE Corrosive Material Transport Semi-Trailer
PTFE's exceptional chemical stability and physical properties make it the ideal choice for storing and transporting corrosive media in industrial applications.
Key Properties of PTFE Lining
- Extreme corrosion resistance: Inert to nearly all chemicals and solvents, resistant to strong acids and bases, and unaffected by organic solvents.
- Wide temperature range: Operational from -196°C to 250°C, maintaining excellent toughness and flexibility across extreme temperatures.
- Non-stick surface: Ultra-low friction coefficient prevents material adhesion, facilitates easy cleaning, and eliminates cross-contamination risks.
- Safe and non-toxic: Biologically inert properties make it suitable for high-purity media transport in food, pharmaceutical, and sensitive industries.
- Insulating and anti-static: High voltage resistance and static electricity control reduce safety hazards during transport operations.
Compared to traditional rubber and polyethylene linings, PTFE-lined semi-trailers deliver extended service life, reduced maintenance requirements, and enhanced transportation safety. The smooth interior surface promotes efficient cleaning and complete media discharge, minimizing residue and optimizing transport efficiency.
Manufacturing Process of PTFE Lining
Our specialized vehicle linings are crafted with precision using tight-lining or loose-lining processes, ensuring perfect tank adhesion and leak-proof performance.
- Tank Pre-treatment: Steel surfaces undergo sandblasting to remove rust and contaminants, creating a clean, smooth substrate.
- PTFE Sheet Inspection: Each sheet undergoes electrical spark detection testing to verify absence of pinholes and defects.
- Precision Fitting and Welding: Thermal press lap welding or manual welding techniques achieve weld strength coefficients exceeding standard requirements, preventing delamination and cracking during long-term use.
- Multiple Quality Inspections: Post-welding electrical spark leak detection followed by hydrostatic testing ensures no bulges, leaks, or imperfections.
Applications of PTFE-Lined Semi-Trailers
PTFE-lined semi-trailers are engineered for demanding industrial applications including:
- Transporting strong acids including hydrochloric acid, sulfuric acid, and hydrofluoric acid
- Handling strong alkaline substances such as sodium hydroxide and ammonia solutions
- Carrying highly corrosive liquids including organic solvents and chemical reagents
- Materials with stringent cleanliness requirements, including pharmaceutical intermediates and high-purity chemicals
