LNG & LPG Hose

Product Overview

LNG LPG Hose is a specialized rubber hose designed for the safe transfer of liquefied petroleum gas (LPG) and liquefied natural gas (LNG) in industrial and commercial applications. This high pressure hose meets international standards for gas transfer, ensuring safety, reliability, and long service life in refineries, gas stations, and chemical plants.

By definition, an LNG LPG Hose must resist gas permeation, spontaneous ignition, and extreme temperatures. As a trusted manufacturer in China, we produce hoses that comply with EN 1762, EN 13766, and GB/T 3683-2011 standards. The core structure combines a smooth UHMWPE and EPDM synthetic rubber tube, high tensile textile cord reinforcement with helix steel wire, and an oxidation-resistant synthetic rubber cover.

Key performance parameters include a working pressure of 20 bar (300 psi) and burst pressure of 60 bar (900 psi) across all sizes from 3/16″ to 1/2″. The hose operates reliably from -25°C to 70°C, with a standard length of 100 meters (330 feet) per roll. This Wire Spiral Hose delivers excellent flexibility, heat aging resistance, and corrosion resistance.

Primary applications include oil fields, refineries, chemical plants, liquefied gas stations, domestic LPG systems, and industrial ammonia transfer. The hose effectively solves critical pain points: gas odor permeation, hose cracking under temperature extremes, external damage from abrasion, and connection leaks at fittings.

As a quality-assured supplier from China, we provide full traceability, ISO certification, and OEM ODM services. Each hose undergoes 100% factory pressure testing before delivery.

Product Advantages

• High Pressure Performance: Rated at 20 bar working pressure and 60 bar burst pressure – a 3:1 safety factor for LPG and LNG applications.
• Excellent Gas Compatibility: UHMWPE and EPDM tube resists swelling from propane, butane, ammonia, and organic solvents.
• Anti-Kink Helix Wire: Embedded steel wire prevents collapse under vacuum and maintains round cross-section during bending.
• Weather and Ozone Resistance: Synthetic rubber cover resists cracking from UV, ozone, and outdoor exposure.
• Wide Temperature Range: Reliable from -25°C to 70°C, suitable for diverse climates.
• Flexible and Lightweight: Easy to handle and route in confined spaces compared to metal pipes.

Applicable Users: Engineering procurement teams, gas station operators, chemical plant maintenance managers, LPG wholesale distributors, and facility management departments needing bulk supply.

Detailed Technical Specifications Table

Below is the complete LNG LPG Hose specification (20 bar working pressure, 60 bar burst pressure, 100 m standard length). For the full PDF specification document, contact our service team.

Structure and Materials

• Tube (Inner Layer): Smooth UHMWPE and EPDM synthetic rubber – ensures low flow resistance and prevents gas permeation. Compatible with LPG, LNG, ammonia, and propylene.
• Reinforcement (Middle Layer): High tensile textile cord with helix steel wire – provides burst strength and kink resistance. This Wire Spiral Hose design balances radial and axial forces under pressure.
• Cover (Outer Layer): Oxidation and corrosion-resistant synthetic rubber – protects against abrasion, oil, ozone, and weather.

Why Does LNG LPG Hose Use Helix Steel Wire?

LNG LPG Hose uses helix steel wire reinforcement for two main reasons:

• Vacuum Resistance: Prevents collapse under suction or negative pressure during gas withdrawal.
• Kink Prevention: Maintains a minimum bend radius, preventing flow restriction and inner tube damage.

All hoses meet a 3:1 burst-to-working pressure ratio, aligned with EN and ISO standards for gas service. Our internal pulse tests exceed 200,000 cycles at 20 bar and 70°C, simulating 10+ years of field service.

Application Industries

Application Scenarios

• Oil Fields and Refineries: Transfer of LPG, LNG, and propylene between processing units and storage tanks.
• Chemical Plants: Handling liquid ammonia and organic solvents.
• Liquefied Gas Stations: Dispensing hoses for vehicle refueling and bulk transfer.
• Industrial Heating Systems: Fuel supply lines for industrial furnaces and boilers.
• Domestic LPG Systems: Regulator-to-appliance connections.
• Agricultural Sector: Ammonia transfer for fertilizer application systems.

Precise Selection Professional Guide

Hose Assembly and Fittings Integration

To create a complete hose assembly, select appropriate fittings based on your application pressure and media. Our solution includes:

• Crimped fittings: Permanently attached for high-pressure gas service – recommended for most LPG applications.
• Reusable fittings: Field-attachable for emergency repairs or custom lengths.
• Adapters and flanges: For connecting to storage tanks, pumps, and dispensers.
• Protective sleeves and guards: Added abrasion resistance for drag-chain or high-traffic areas.

All hose assembly work is performed at our ISO-certified facility with 100% pressure testing before shipment.

2. Bend radius: Never exceed the minimum bend radius (typically 5x O.D.) to prevent kinking.
3. Fitting attachment: Use only crimped fittings or reusable fittings rated for gas service.
4. Storage: Keep in a cool, dry place away from direct sunlight and ozone sources.
5. Pressure testing: After assembly, test at 1.5x working pressure using dry nitrogen – never use oxygen.
6. Replacement schedule: Replace every 5 years or immediately if leakage, hardening, or cracking appears.
