Pipe IVAR.INOX - stainless steel AISI 304 L - 18mm; 1mm - 6m IVAR.IVINT4

Product detailed description

Stainless steel pipes are essential components in systems requiring high corrosion resistance and long-term reliability. They are commonly used in residential, commercial and industrial buildings for heating circuits, hot water supply, compressed air systems and other technical installations. Installers working in medical facilities, laboratories or chemical plants often choose stainless steel due to its inert properties and ease of cleaning. This pipe variant is suited for press-fit systems and is compatible with fittings requiring external threading for secure connections.

Proper selection of pipe size and material is crucial for system performance. Stainless steel ensures resistance to scaling and microbial growth, making it ideal for environments where hygiene is critical. The pipe’s smooth inner surface reduces friction losses and supports efficient fluid flow. It is particularly well-suited for closed-loop systems and applications where the medium requires high purity.

Technical parameters

Installation and connection

For press-fit connections, ensure the pipe is cut cleanly and free of burrs using a suitable pipe cutter. Insert the pipe into the fitting and apply the press tool according to the manufacturer’s instructions. When connecting with external threading, use a thread sealant compatible with stainless steel to prevent leakage. Always verify the alignment of the fitting before pressing. Common mistakes include over-pressing the joint, which can damage the fitting, and using incorrect cutting tools that deform the pipe wall.

Compatibility and accessories

This pipe is designed for use with IVAR press-fit fittings and threaded adapters. For external threading connections, additional sealing materials such as PTFE tape or anaerobic sealants may be required. Ensure all fittings are compatible with stainless steel and the intended application. Accessories such as elbows, tees and valves should be selected based on the system layout and flow requirements.

Technical background for designers

Stainless steel pipes operate under the principle of mechanical strength and chemical stability. The low-carbon content of AISI 304L prevents sensitisation during welding, ensuring structural integrity. The smooth inner surface reduces turbulence and supports laminar flow. Integration into a system requires consideration of thermal expansion, especially in long runs. Proper support spacing and expansion joints may be necessary to accommodate movement. The material’s resistance to oxidation and chlorides enhances service life in aggressive environments.

Service and operation

Stainless steel pipes require minimal maintenance due to their passive oxide layer. However, regular visual inspections for signs of mechanical damage or corrosion are recommended. In high-purity systems, periodic flushing with deionised water may be necessary to remove particulate matter. No scheduled service intervals are required unless specified by the system operator or local regulations.

Frequently asked questions

Can IVAR.INOX 18mm be connected to press-fit fittings?
Yes, this pipe is specifically designed for press-fit connections. Use a certified press tool and follow the manufacturer’s guidelines for pressing force and depth.

Is this stainless steel pipe suitable for hot water systems?
Yes, it is approved for use in sanitary and heating applications, including hot water distribution. Ensure the system operating temperature does not exceed the material’s limits.

Can the pipe be welded without compromising its properties?
Yes, the low-carbon content of AISI 304L minimises the risk of intergranular corrosion after welding. Post-weld cleaning is recommended to remove slag and oxides.

What sealing methods are suitable for threaded connections?
Use PTFE tape or anaerobic sealants compatible with stainless steel. Avoid oil-based or acidic compounds that could degrade the oxide layer over time.
