Industry Hose Heavy Duty Performance Flexible Operation Reliable Quality

Description

The Phosphoric Acid Hose is a highly specialized transfer hose engineered for the safe and efficient movement of concentrated phosphoric acid in industrial and maritime environments. Unlike general-purpose chemical hoses, it is formulated with an acid-resistant elastomeric inner tube that maintains chemical integrity and flexibility even under prolonged exposure to orthophosphoric acid at concentrations up to 85%. Its design incorporates multi-layer reinforcement for mechanical stability, a smooth bore to prevent crystallization, and a rugged outer cover resistant to abrasion, UV exposure, and environmental hazards. This hose is ideal for applications where precision, durability, and safety are critical, such as fertilizer production plants, phosphoric acid terminals, and bulk transport systems.

Case Study: Offshore Fertilizer Transfer – Corrosion-Resistant Solution

An offshore fertilizer transfer facility in the Gulf of Mexico faced repeated hose failures during phosphoric acid offloading from supply vessels to storage tanks. The prior hoses, rated for general chemical service, deteriorated quickly due to high acid concentrations and dynamic flexing caused by vessel movement. Frequent replacements led to operational delays and safety risks due to acid exposure.

Hongruntong Marine supplied Phosphoric Acid Hoses specifically engineered for offshore use. These hoses featured an acid-resistant inner tube, spiral synthetic reinforcement layers for mechanical stability, and a UV/abrasion-resistant outer cover suitable for harsh marine conditions. The hoses were installed with specialized floating supports to accommodate vessel motion, reducing bending stress and extending service life.

After 12 months of continuous offshore service, inspections showed no evidence of liner degradation or reinforcement separation. Flow consistency improved due to the smooth inner bore, and the maintenance team reported a significant reduction in downtime. Additionally, the facility achieved measurable safety improvements, as the hoses eliminated minor leaks and acid drips previously observed with standard chemical hoses.

This case demonstrates that Phosphoric Acid Hoses provide reliable, long-term service in challenging offshore conditions, ensuring both operational efficiency and safety during critical transfer operations.

Specifications

Key Features

Specialized Acid Resistant Inner Tube

The inner tube of this Phosphoric Acid Hose is formulated to resist chemical attack from high-concentration phosphoric acid. The elastomeric compound maintains tensile strength and flexibility even under sustained exposure to hot acid, preventing softening, blistering, or contamination of the transferred chemical. Laboratory testing confirms excellent dimensional stability, providing reliable service in both static and dynamic operations.

Multi Layer Reinforcement for Mechanical Integrity

The hose features multiple spiral layers of synthetic fiber reinforcement, bonded to withstand internal pressure, vacuum conditions, and bending stresses. This structure prevents kinking and collapse, ensuring the hose remains round and maintains flow efficiency. Reinforcement bonding is optimized to resist delamination under repeated operational cycles, particularly important in offshore and industrial transfer applications.

Smooth Bore Design to Minimize Crystallization

The inner surface of the Phosphoric Acid Hose is precision-engineered to provide a smooth, low-turbulence bore. This design reduces stagnation zones where phosphoric acid could crystallize, improving flow consistency and minimizing the need for frequent cleaning. Enhanced bore smoothness also contributes to energy efficiency in pumping operations.

Rugged Outer Cover for Environmental Protection

The hose is equipped with a heavy-duty outer cover resistant to UV light, ozone, abrasion, and chemical splashes. This cover protects the hose in harsh industrial and offshore conditions, allowing safe handling, dragging, and installation without compromising the reinforcement layers. Flexibility is maintained across temperature ranges to ensure reliable manipulation and storage.

Applications

Offshore Phosphoric Acid Transfer

Ideal for marine transfer between vessels and storage tanks, this Phosphoric Acid Hose withstands dynamic flexing, chemical exposure, and environmental challenges typical of offshore operations. Smooth bore and acid resistance ensure uninterrupted flow and prevent crystallization during extended transfer cycles.

Fertilizer Production Feedstock Handling

Used to convey phosphoric acid from storage to reactors or blending units, this hose maintains purity and consistent flow while resisting thermal and chemical stress. It ensures precise dosing and reduces contamination risks in fertilizer manufacturing processes.

Bulk Storage and Terminal Loading

Designed for tank farms and bulk terminal operations, the Phosphoric Acid Hose supports high-pressure loading, suction, and repeated handling. Reinforcement and abrasion-resistant outer cover make it suitable for dockside or warehouse environments.
