Multichem PTFE: Standard Duty
Multichem PTFE composite hoses are specialized flexible hoses that have been engineered for handling of highly aggressive chemicals like phosphoric acid, nitric acid, sulphuric acid and solvents including chlorides and fluorides. These hoses are designed to provide excellent resistance to the corrosive and reactive nature of such chemicals while maintaining flexibility and durability. The core of the hose is made of PTFE (Polytetrafluoroethylene), which is a synthetic fluoropolymer known for its exceptional chemical resistance and non-stick properties. PTFE is well-suited for handling aggressive chemicals and can withstand a wide range of corrosive substances.
Compliance : Multichem PTFE hoses are manufactured in accordance to EN 13765 / 2018 Type 2

Applications
Chemical Processes: Compohose is ideal for use in chemical manufacturing and processing plants. Its resistance to a wide range of aggressive chemicals, solvents, and acids makes it suitable for transferring raw materials, intermediates, and finished products within the chemical industry.
In-Plant Transfers: Compohose can be employed for transferring chemicals and fluids within the confines of a manufacturing facility. It can handle corrosive substances safely, ensuring the integrity of the hoses and preventing leaks or contamination during in-plant transfers.
Storage Tank Transfer: When loading or unloading chemicals to and from storage tanks, Compohose can be relied upon. Its compatibility with aggressive chemicals ensures safe and efficient transfer operations, reducing the risk of leaks and spillage.
Aggressive Chemical Transfers: Compohose is designed to handle a wide range of aggressive chemicals, including chloride and fluoride compounds. This makes it suitable for transferring chemicals that might otherwise corrode or degrade traditional hose materials.

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 13765 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.
