Gas-tight protector KOT-GAS, 40

Product detailed description

The IVAR KOT-GAS 40 is a gas-tight protective sleeve designed for use in gas pipe systems where mechanical protection and leak prevention are essential. It is commonly used in residential, commercial and industrial gas installations, particularly in applications involving corrugated stainless steel or copper gas piping. The sleeve is installed over the pipe to provide an additional layer of protection against physical damage and to contain any potential gas leakage. It is especially useful in concealed spaces such as wall cavities, under floors or within ceiling voids, where access for inspection or maintenance is limited. The KOT-GAS 40 is designed for use with press-fit or compression fittings and is selected according to the system pressure rating and pipe dimensions.

During installation, the sleeve is slid over the corrugated pipe and positioned to cover joints and vulnerable areas. It is important to ensure that the sleeve is not cut or damaged during handling and that it is fully sealed at both ends to maintain gas-tight integrity. The sleeve is not intended to replace the primary sealing function of the pipe connections but to provide secondary protection in case of failure. The KOT-GAS 40 is typically used in conjunction with other components such as press-fit fittings and corrugated pipe sections of appropriate dimensions.

Technical parameters

Nominal pressure	PN 704
Weight	0.235 kg
Code	79740136
Brand	IVAR

The nominal pressure rating of PN 704 indicates the maximum operating pressure for which the gas-tight protector is suitable. This is a critical factor in system design, as the protector must be compatible with the pressure class of the entire gas distribution system. The 40 dimension refers to the nominal size of the corrugated pipe it is intended to cover, ensuring a snug fit and effective protection. The 25 m roll length allows for continuous installation in long runs, reducing the need for multiple sections and potential leak points.

Installation and connection

The installation process involves sliding the KOT-GAS 40 sleeve over the corrugated pipe before or after the pipe is connected to the system. It is important to ensure that the sleeve is positioned to fully cover all joints and connections. The sleeve must be sealed at both ends using appropriate methods to maintain gas-tight integrity. If the system uses IVAR.PRESS-GAS press-fit connections, the corrugated pipe must be one size larger than the connection to ensure proper fit and function. Common installation mistakes include cutting the sleeve to length before sealing, which can compromise its effectiveness, and failing to cover all joints and vulnerable areas. Installers should also verify that the sleeve is not kinked or damaged during installation, as this can affect its performance.

Compatibility and accessories

The KOT-GAS 40 is compatible with corrugated gas pipes of nominal size 40 and is intended for use with press-fit or compression fittings. It is typically used in conjunction with IVAR.PRESS-GAS fittings and other components of the same system. When using press-fit connections, it is essential to use a corrugated pipe of the next larger dimension to ensure a secure fit. Additional accessories such as sealing compounds or end caps may be required to ensure full gas-tightness. The protector is not interchangeable with other sizes or types and must be selected based on the specific system requirements and pipe dimensions.

Technical background for designers

The KOT-GAS 40 operates by forming a secondary barrier around the corrugated gas pipe, preventing the escape of gas in the event of a primary seal failure. It is constructed from materials that are resistant to gas permeation and are compatible with the operating conditions of the system. The sleeve is designed to maintain its integrity under normal operating pressures and temperatures, and it is intended to be installed in a way that does not restrict the flexibility of the corrugated pipe. The service life of the protector is influenced by factors such as installation quality, environmental conditions and the integrity of the primary connections. Proper design and installation are essential to ensure that the protector functions as intended and does not become a source of system failure.

Service and operation

The KOT-GAS 40 requires no regular maintenance under normal operating conditions. However, it is important to inspect the sleeve periodically for signs of damage, wear or gas leakage. Any damage to the sleeve should be repaired or replaced immediately to prevent potential hazards. During operation, the sleeve should remain intact and free from obstructions. If the system is decommissioned or modified, the sleeve should be removed and replaced as necessary to maintain system integrity. There are no specific service intervals provided for this product, but it should be treated as part of the overall system maintenance plan.

Frequently asked questions

Can the KOT-GAS 40 be used with press-fit fittings?
Yes, the KOT-GAS 40 is compatible with press-fit fittings. However, the corrugated pipe must be one size larger than the fitting to ensure a proper fit and maintain gas-tight integrity.

Is the KOT-GAS 40 suitable for concealed installations?
Yes, the KOT-GAS 40 is designed for use in concealed spaces such as wall cavities, under floors or within ceiling voids. It provides mechanical protection and leak prevention in areas where access for inspection is limited.

Can the KOT-GAS 40 be cut to length during installation?
No, the KOT-GAS 40 should not be cut to length before sealing. Cutting the sleeve can compromise its gas-tight integrity and reduce its effectiveness in preventing leaks.

What is the maximum operating pressure for the KOT-GAS 40?
The KOT-GAS 40 is rated for a nominal pressure of PN 704. This indicates the maximum operating pressure for which the protector is suitable and must be considered when designing the gas distribution system.
