Alkali Resistant Rubber Hose Strong Alkali Protection Robust Structure Long Lifespan

Description

The Phosphoric Acid Hose by Hongruntong Marine is engineered specifically for the demanding conditions of concentrated phosphoric acid transfer. Its design combines a chemical-resistant inner tube, multi-layered reinforcement, and a durable outer cover to provide mechanical strength, chemical stability, and environmental resistance. This hose ensures smooth flow, prevents crystallization, and maintains integrity under dynamic and high-pressure conditions common in industrial and marine operations. Unlike general-purpose chemical hoses, it is formulated to withstand the aggressive nature of phosphoric acid, maintaining flexibility and performance over prolonged service periods.

Case Study: High Temperature Fertilizer Reactor Feed

A fertilizer manufacturing plant in Northern Europe faced challenges in feeding concentrated phosphoric acid into high-temperature reactors. Standard chemical hoses were failing due to chemical attack, thermal stress, and frequent flexing. Downtime and hose replacements increased operational costs and interrupted production schedules.

Hongruntong Marine supplied Phosphoric Acid Hoses designed to endure high temperatures (~75°C) and continuous chemical exposure. These hoses featured an acid-resistant inner tube, spiral-reinforced layers for structural integrity, and a smooth internal bore to reduce crystallization. Custom-length assemblies with reinforced end fittings were installed to accommodate tight plant layouts.

After 18 months of continuous use, inspections confirmed the hoses maintained their internal and external integrity. Flow rates were stable, energy consumption for pumping decreased due to reduced friction losses, and contamination incidents from hose wear were eliminated. Maintenance staff reported a 40% reduction in replacement frequency, and overall production efficiency improved. This case highlights the critical role of a purpose-built Phosphoric Acid Hose in high-temperature industrial chemical operations.

Specifications

Key Features

High Temperature and Acid Resistant Inner Tube

The inner tube is formulated to resist both high-concentration phosphoric acid and elevated temperatures. The elastomeric compound maintains mechanical properties over long-term exposure, ensuring chemical purity and preventing liner degradation. Laboratory testing confirms stability under thermal cycling and prolonged immersion.

Multi Spiral Reinforcement for Strength and Flexibility

The hose incorporates multiple spiral layers of synthetic fiber reinforcement to provide strength under internal pressure, suction, and bending. This design prevents collapse during vacuum operation and maintains roundness, ensuring consistent flow even under mechanical stress.

Smooth Bore for Consistent Flow and Crystallization Prevention

The inner surface is precision-engineered to minimize turbulence, reducing the risk of crystallization and deposit formation. This ensures stable pumping and transfer operations while maintaining product purity.

Durable Outer Cover for Harsh Environments

The outer cover is abrasion-resistant, UV-protected, and ozone-resistant, enabling safe handling in industrial plants and marine terminals. It preserves reinforcement integrity and maintains flexibility under temperature variations, allowing safe storage and manipulation.
