Food Grade Hoses Safe Material Odor Free Hygienic Transfer Stable Performance
Description
The Phosphoric Acid Hose from Hongruntong Marine is engineered for high-performance transfer of concentrated phosphoric acid in demanding industrial and marine environments. Its specialized inner tube provides exceptional chemical resistance, maintaining integrity and flexibility under exposure to orthophosphoric acid at concentrations up to 85%. The multi-layer reinforcement ensures mechanical stability under internal pressure, suction, and bending loads, while the outer cover provides abrasion, UV, and environmental protection. Smooth bore design reduces crystallization risk and ensures consistent flow, making it ideal for terminals, fertilizer plants, and bulk transport systems.
Case Study: Inland Fertilizer Terminal Long Distance Transfer
An inland fertilizer terminal in South America required a long-distance phosphoric acid transfer hose capable of spanning over 80 meters from storage tanks to blending units. Previous hoses failed due to chemical degradation, internal crystallization, and structural collapse during suction operations. Downtime and hose replacement costs were significant, affecting production schedules.
Hongruntong Marine supplied Phosphoric Acid Hoses specifically designed for long-distance transfer. These hoses featured a chemically resistant inner tube, multiple spiral reinforcement layers for structural integrity, and a smooth bore to minimize crystallization. Heavy-duty outer covers protected against abrasion and environmental exposure, while customized end fittings ensured proper integration with existing piping and pumping systems.
After 15 months of continuous service, internal inspections confirmed that the hoses maintained structural and chemical integrity. Flow rates remained consistent, and maintenance downtime was reduced by 35%. The terminal reported zero contamination events due to hose wear, demonstrating that a purpose-built Phosphoric Acid Hose significantly improves operational reliability, product purity, and cost efficiency in long-distance industrial transfer applications.

Key Features
Specialized Inner Tube for High Concentration Phosphoric Acid
The inner tube is formulated to withstand aggressive phosphoric acid environments, retaining tensile strength, flexibility, and chemical resistance under prolonged exposure and elevated temperatures. It prevents liner degradation, softening, and contamination, ensuring consistent transfer performance.
Multi Layer Reinforcement for Structural Stability
Multiple spiral layers of synthetic fiber reinforcement provide resistance to internal pressure, vacuum, and mechanical stress. This prevents kinking, collapse, and deformation, ensuring reliable performance in both suction and pressure applications.
Smooth Bore for Efficient Flow
The smooth inner surface minimizes turbulence and prevents crystallization, ensuring consistent flow rates and reducing maintenance requirements. Optimized bore geometry also enhances pumping efficiency and reduces energy consumption.
Durable Outer Cover for Harsh Environments
The outer cover provides protection against abrasion, UV exposure, ozone, and environmental hazards. It ensures safe handling, preserves structural integrity, and maintains flexibility across temperature variations for reliable operation.
