1. Product Overview
In fine chemical industry, metallurgical pickling, electroplating and petrochemical engineering, 98% concentrated sulfuric acid is classified as a highly corrosive and strongly oxidizing medium. Conventional rubber, PVC and plastic hoses are prone to corrosion, leakage, medium contamination and high-temperature aging failure, failing to meet the requirements of long-term continuous industrial transportation. LETONE industrial
PTFE hose for concentrated sulfuric acid adopts high-purity virgin PTFE inner liner and stainless steel braided reinforcement. With a standard caliber of
1/2 inch, rated working pressure of
16Bar and continuous temperature resistance up to
200°C, it is a professional pipeline designed for concentrated sulfuric acid, oleum and other high-temperature corrosive media, delivering excellent chemical stability and working condition adaptability.
2. Professional Three-Layer Composite Structure
This 1/2 inch 16Bar high-temperature acid-resistant PTFE hose adopts an integrated three-layer composite structure to ensure comprehensive performance of corrosion resistance, pressure resistance and high-temperature stability for harsh chemical working conditions.
Inner Tube: High-purity Virgin PTFE
Virgin PTFE features extreme chemical inertness, fully resistant to 98% concentrated sulfuric acid, oleum, strong nitric acid, strong alkalis, oxidants and organic solvents. No swelling, decomposition or precipitation occurs under high temperature, avoiding secondary medium pollution. The ultra-smooth inner wall prevents scaling and blockage to ensure stable fluid transmission.
Reinforcement Layer: High-density Stainless Steel Braid
Precision stainless steel braided structure provides uniform stress distribution, enhancing structural strength and tensile resistance. It stably bears the rated working pressure of 16Bar, adapting to pump pressurized delivery, closed-loop circulation and continuous high-pressure industrial transmission with excellent hydraulic impact resistance and structural stability.
Outer Protective Layer: High-temperature and Corrosion Resistant Cover
The modified outer cover resists high-temperature aging, acid mist corrosion, UV radiation and weathering, effectively protecting the hose body from external mechanical wear and chemical erosion to extend service life in complex chemical workshops.

4. Core Performance Advantages
Strong Resistance to Concentrated Sulfuric Acid Corrosion
The chemically inert PTFE liner completely solves the corrosion and leakage problems caused by concentrated sulfuric acid, making it a professional PTFE hose for concentrated sulfuric acid transmission with far superior durability compared with traditional pipeline materials.
200°C Ultra-high Temperature Resistance
Stable performance at continuous high temperature of 200°C without softening, deformation or cracking, perfectly suitable for hot acid circulation, high-temperature pickling and chemical reactor feeding processes.
The stainless steel braided structure ensures reliable high-pressure performance, adapting to industrial pressurized delivery and closed circulation systems without bulging or bursting risks.
Self-cleaning and Anti-scaling Performance
The non-stick smooth inner wall prevents medium crystallization and scaling, reducing maintenance frequency and ensuring high-purity fluid transmission for precision chemical production.
5. Industrial Application Scenarios
This 200°C high-temperature 16Bar acid-resistant PTFE hose is widely used in concentrated sulfuric acid transmission pipelines, metallurgical pickling lines, electroplating acid-base delivery systems, chemical reactor circulation pipelines, petrochemical corrosive fluid transmission and laboratory high-corrosion medium delivery systems, serving as the preferred pipeline for high-temperature, high-pressure and strong-corrosion working conditions.
