Episode 1: Risk minimization in the transport of hazardous media

Handling hazardous media requires actions in the plant design to protect our environment, employees’ health and safety, and consistent end-product quality. Due to environmental pollution and heavy accidents, organizations must ensure that their activities do not cause harm to anyone.

Episode 2: Global Service and Support

When designing double containment systems, material properties must be considered in relation to operational and external factors. Such influencing factors can lead to mechanical, thermal and chemical stresses. These stresses and consequences must be calculated. The experts at GF Piping Systems offer individual support and advice in selecting the right material and calculate the static evidence for your specific application.

Episode 3: Installation

GF Piping Systems’ double containment system CONTAIN-IT Plus is your solution to prevent costly environmental pollutions, reduce employee accidents, and ensure higher end-product quality and plant availability. Digital libraries, material experts, technical documentations, standard and advanced engineering services, and a broad standard portfolio with all relevant tools ensure the right fit for all individual projects.

Episode 4: Quality & Safety

To minimize the risk of leakage to zero, selecting the suitable piping system material is crucial, considering the project-specific operating conditions. GF Piping Systems offers an online chemical resistance tool to choose the appropriate material for pipes and gaskets and select the right jointing technologies. Also, the experts of GF Piping Systems are ready to support individual assessments of project-specific operating conditions.

Episode 5: Advanced Engineering Services

Double containment systems are installed and operated in very demanding applications and areas: The systems must withstand temperature fluctuations, pressure, and highly aggressive chemical mixtures, such as wastewater. The Advanced Engineering Services team at GF Piping Systems ensures that the system can be operated safely over its intended service life by performing appropriate calculations such as structural analysis.

System Flexibility

Designed for industrial applications with a strong focus on easy and safe installation for a wide range of dimensions and inner pipe materials to ensure a long lifetime and an efficient operation of the system.

Leak detection system

Reliable leak detection solutions combined with a variety of system connections contributes to a fast troubleshooting and a safe system condition.

Unique joining technology

Unique, easy and safe joining technology in compliance with DVS guidelines enables a visual inspection of the inner pipe before closing the outer pipe.

Standard Service

Concerns about your system design – not with the free of charge standard service based on the questionnaire for static evidence & stress calculation, which provides further information about the feasibility and fix point forces.

Plastic Pipes

Sturdy and lightweight, plastic pipes are ideal for use in a wide range of applications. Versatile yet durable, these all-rounders offer exceptional reliability and proven quality.

Double Containment Pipes

Double containment pipes provide optimal safety for high-risk and highly demanding applications. The double containment system prevents the leakage of hazardous materials and protects human beings, the environment and production equipment. There are visually or automated leak-monitoring systems.

Adapters & Transitions

Adapters and transitions are essential for connecting metal with plastic pipes or even two plastic pipes. This range covers multiple materials and offers reliable connections while offering high flexibility during assembly.

Bends & Elbows

Bends and elbows are essential fittings that easily change the direction of pipes. The extensive range available offers not only multiple materials but also different curvature degrees to easily fit your piping system.

Couplers & Sockets

Simplify the pipe installation process with couplers and sockets. Specially designed to slide easily over pipes with no extra equipment required, they are cemented, welded or mechanically connected to create a pressure-tight joint.


Reducers are used for effecting a smooth transition between two pipes or fittings with different dimensions. The wide selection available covers an exceptionally diverse area of applications. They are available in short or long versions and in centric or excentric versions.

Tees, Y-Pieces and Crosses

When creating branch lines, lightweight tee, wye, and cross fittings make installation much easier. These fittings are made from a range of materials and malleable iron and cover multiple dimension possibilities including various reductions on the same fitting.


Unions are the best mechanical connection between pipe segments and for installing all kinds of components up to the dimensions of d110/DN100. Unions are available in a wide range of materials and jointing options. The connection is fast and very robust.

Termination Fittings

Termination fittings represent the beginning and the end of a double containment system and seal the monitoring room. For complex isometrics, end fittings are used to segment the monitoring room.

Ball Valve 546 Pro

The original just got better.
The ball valves from GF Piping Systems do not compromise on safety. Special design features ensure high reliability and long service life. For example, there are no metal components in areas that are in contact with the medium that could corrode during use. A predetermined break point integrated in the stem interface prevents leaks due to wear or excessive force. Two o-rings integrated into the stem interface provide maximum protection.

2-way Diaphragm Valve

Intended for use in numerous applications from chemical processing to water treatment, GF Piping System offers a wide range of diaphragm valves. This includes manual, pneumatic and electric operation combined with all plastic and diaphragm materials.

Infrared (IR) Fusion Machines

IR fusion machines, designed and produced by GF Piping Systems, meet the highest demands of mechanical stability, reproducibility and quality of fusion jointing. Typical application areas include the process and microelectronic industry.

MSE 63/119 Socket Fusion Toolset

This socket fusion toolset contains everything required to perform fusion jointing on site. Suitable for all commonly used plastics and featuring a long service life, the set guarantees extremely accurate temperature control for strong, consistent joints.

Peeling and Chamfering Tools

GF Piping Systems takes the hassle out of peeling and chamfering. Easy to use peeling tools ensure consistent peeling quality when preparing pipesurfaces while chamfering tools are designed to chamfer pipes of various diameters in no time at all.


We provide a wide range of accessories to support your installation projects. Accessories are available for use throughout the life-cycle of your system and available in an agreed time-frame.
