PTFE Composite Hose SST for Ship-to-Shore Sulfuric Acid Transfer Systems

Reliable Flexible Piping Solution for 99% Sulfuric Acid Handling in Chemical Terminals

In chemical transportation and terminal operations, ship-to-shore transfer systems require flexible hoses with excellent corrosion resistance, pressure capability, and long-term reliability.

For concentrated acid transfer applications, hose selection is critical. The wrong material choice may lead to corrosion, leakage risk, and unexpected maintenance costs.

For an Australian chemical terminal project, CJan Fluid Technology Co., Ltd. provided the SST PTFE Composite Hose solution for ship-to-shore sulfuric acid unloading operations.

The hose is designed for transferring 99% sulfuric acid under DN200, PN1.6MPa working conditions, providing a safe and reliable connection between vessels and shore-based storage systems.


Project Background

The project was developed for a ship unloading system where concentrated sulfuric acid needs to be transferred from vessels to onshore storage facilities.

Due to the nature of ship-to-shore operations, the transfer hose must handle changing working conditions, including:

  • Vessel movement caused by waves and tides
  • Flexible connection requirements
  • High corrosion resistance requirements
  • Long-distance transfer connections

A flexible PTFE composite hose was selected to replace traditional rigid piping solutions and provide safer operation flexibility.


Project Requirements

Application:
Ship-to-shore sulfuric acid unloading system

Industry:

  • Chemical terminal
  • Bulk chemical transportation
  • Acid handling system

Medium:

  • 99% Sulfuric Acid (H₂SO₄)

Operating Temperature:

  • Ambient temperature

Working Pressure:

  • PN1.6MPa

Size:

  • DN200

Length:

  • 10 meters per hose

Connection:

  • Stainless steel loose flange on both ends

Challenges in Sulfuric Acid Transfer Applications

1. High Corrosion Resistance Requirements

Concentrated sulfuric acid is highly corrosive and requires carefully selected hose materials.

Common rubber or standard metal hoses may experience:

  • Chemical degradation
  • Internal corrosion
  • Reduced service life
  • Increased maintenance requirements

Therefore, the hose lining material must provide excellent chemical resistance.


2. Flexible Connection Between Ship and Shore

Unlike fixed pipeline systems, ship unloading operations require flexibility due to:

  • Ship movement
  • Position changes during loading/unloading
  • Installation limitations

The transfer hose needs to absorb movement while maintaining stable performance.


3. Large Diameter and Pressure Performance

For DN200 large diameter applications, the hose must provide:

  • Reliable pressure resistance
  • Stable structure
  • Secure flange connection
  • Long-term operational safety

This requires a composite hose structure designed specifically for industrial chemical transfer.


Recommended Solution: SST PTFE Composite Hose

Based on the application requirements, CJan Fluid Technology Co., Ltd. recommended the SST PTFE Composite Hose.

The SST series combines a PTFE inner lining with multi-layer reinforcement technology, providing excellent resistance against aggressive chemicals while maintaining flexibility.

It is suitable for:

  • Sulfuric acid transfer
  • Chemical unloading systems
  • Corrosive liquid transportation
  • Industrial chemical processing
