Red 27mm (3/4″) ABS Aspirating Pipe Socket

FAQ

What is the purpose of the REDMAP0250 socket?

The REDMAP0250 is a plain socket designed to join two lengths of 27mm (3/4″) pipe in aspirating smoke detection systems. It provides a secure, permanent connection between pipe sections, creating a leak-free joint when properly installed with ABS solvent cement. The socket is essential for building the pipe networks that transport air samples from protected areas to the detector.

Which pipe sizes is this socket compatible with?

The REDMAP0250 is designed specifically for 27mm (3/4″) diameter ABS pipe used in aspirating smoke detection systems. It connects two pieces of pipe of the same 27mm (3/4″) diameter, creating a secure joint in the air sampling network.

Which aspirating smoke detection systems can this socket be used with?

The REDMAP0250 is compatible with all major brands of low-pressure aspirating smoke detection systems, including VESDA, FAAST, ICAM and other leading ASD manufacturers. The socket meets the industry standards required for these systems and is designed specifically for aspirating pipe networks.

What material is the socket made from and why?

The socket is manufactured from red ABS (Acrylonitrile Butadiene Styrene) plastic. ABS is chosen for its superior physical properties including excellent tensile strength, chemical resistance, impact toughness, weatherability and heat stability. The material is homogenous with good chemical resistance and high impact strength, performing reliably across temperatures from -40°C to 70°C and providing exceptional resistance to accidental damage.

How do I install this socket?

The socket is installed using ABS solvent cement welding. The process involves cutting the pipe ends squarely, removing all burrs, abrading both the pipe ends and the socket interior, cleaning with MEK cleaner, then applying ABS solvent cement before pushing the pipes fully into both ends of the socket. When correctly made, these joints are stronger than the pipe itself. It is recommended that joints are left to cure for 24 hours wherever possible.

Why is the socket red in colour?

The red colour is the standard for aspirating smoke detection pipes and fittings, serving to instantly identify the components as part of a fire detection system. This visual identification helps prevent accidental damage or interference during building maintenance and clearly distinguishes fire system pipework from other building services.

What standards does this socket comply with?

The REDMAP0250 is manufactured under a stringent quality control system approved to BS EN ISO 9001. The product is tested and certified to EN 54-20 (fire detection and fire alarm systems – aspirating smoke detectors) and EN 61386-1 standards, ensuring full compliance with UK and European fire safety regulations.

Can this socket be used in harsh or extreme environments?

Yes, the ABS material provides excellent chemical resistance to a wide range of acids, alkalis and aggressive chemicals. The socket maintains its impact strength and toughness across temperatures from -40°C to 70°C, making it suitable for demanding environments including cold stores, industrial facilities and outdoor applications. The socket’s robust construction provides exceptional resistance to accidental damage during installation and operation.

What is the difference between a socket and a socket union?

A plain socket (like the REDMAP0250) creates a permanent connection between two pipe sections using solvent cement. Once joined, the pipes cannot be easily separated. A socket union, on the other hand, allows pipes to be joined with the ability to separate them later for maintenance, providing a clean break point in the system. Plain sockets are used for permanent connections, whilst unions are typically used where periodic dismantling may be required.

How many sockets are needed for a typical installation?

The number of sockets required depends on the length and complexity of the pipe network. Sockets are needed wherever two pipe sections meet to create a continuous run. For a typical installation, multiple sockets will be required to join the pipe lengths together to create the complete air sampling network. The specific number should be determined during the system design phase.
