Applications
Refrigerated Transport: Cryogenic hoses are essential for loading and unloading fully refrigerated gases like LNG onto transport vehicles such as trucks, railcars, and ships. The hoses can handle the temperature fluctuations during transit and provide a safe means of transfer.
Industrial Gas Plants: Cryogenic hoses are employed in industrial settings for handling various gases used in processes. These hoses are especially valuable when dealing with gases from Gas Group 4, 5, and 7, as they ensure the safe conveyance of potentially hazardous materials.
Liquefied Natural Gas (LNG) Operations: Cryogenic hoses play a role in LNG facilities, ensuring the smooth transfer of LNG between storage tanks, transport vessels, and processing units.
Cryogenic Storage and Distribution: Cryogenic hoses are used in the storage and distribution of cryogenic gases, including liquid nitrogen, oxygen, and argon, for various industrial processes, such as metal fabrication and medical applications.

Safety Standards
Rigorous Safety Testing
COMPOHOSE assemblies undergo comprehensive testing, conducted at 1.5 times the rated Working Pressure (W.P). This stringent testing adheres to the EN 13766 standard, ensuring a paramount level of safety and reliability.
Provision of Manufacturer's Test Certificate
With each supply of COMPOHOSE composite hose assemblies, a Manufacturer's Test Certificate is included. This certificate serves as a confirmation of the product's quality and compliance with safety standards, providing added assurance to users.
Clear Burst Pressure Specification
The burst pressure of the composite hose is explicitly indicated for ambient temperature conditions. This vital information enhances safety awareness and empowers users to operate within secure pressure limits.
Effective Electrical Continuity
The composite hose's electrical continuity is assured through the integration of two bonded wires connected to the end fitting. This innovative design promotes the dissipation of accumulated electrical charges, mitigating the risk of static flashes and associated hazards.
