AGRU electrofusion welding machines with Short Circuit Protection (SCP) system
Newly available AGRU electrofusion universal machines with built-in SCP (Short Circuit Protection) system, detect short circuit based on variations in fittings heating wire resistance. These resistance changes are detected and evaluated by the SCP system and the welding process is aborted if necessary!
Rely on our expertise and benefit from the complete traceability and documentation of every weld. The SCP system works for all AGRU electrofusion fittings from DN 20 to DN 500 and is integrated into all new AGRU electrofusion welding machines.
AGRU PVDF Supply Range
In order to provide our customers with an even more reliable supply of PVDF semi-finished products, AGRU expanded the PVDF product portfolio. Now it includes two new Homopolymer PVDF grades to provide an alternative to our standard products.
These grades have the typical AGRU PVDF properties and can be used for a wide range of applications, combined with increased availability, and cost competitive options. Currently there is no experiance with the new grades in HP applications. Therefore we would recommend to use our standard Solef materials.

AGRU E-spigot coupler (code 70.172.0250.11)
The AGRU E-spigot coupler offers an efficient solution to the challenges of welding PE 100 / PE 100-RC pipes and spigot fittings. The E-spigot coupler thus offers a practical solution for situations where conventional butt welds are problematic, such as in confined spaces or working overhead.
All AGRU electrofusion fittings are characterized by their high-quality and offer:
- Fully embedded heating wire for easy cleaning and safe installation.
- Generous heating and cooling zones for perfect welding results.
- Excellent shrinkage behavior during welding due to a special production process.

AGRU Flex Restraint
The AGRU Flex Restraint is a flexible bar for electro-socket welding onto PE 100 / PE 100-RC pressure pipes. This way, a rigid system by fixed points can be created that absorbs high forces to prevent axial movement. This special fitting is placed onto the pipe with a tensioning belt and is homogeneously welded by electro-socket welding in accordance with AGRU installation guidelines, based on DVS 2207-1.
The AGRU Flex Restraint offers a strength of 40 KN in axial direction. If higher forces have to be absorbed, several Flex Restraints are to be distributed around the circumference.
Material: PE 100-RC
Shear strength: 40 KN
Main Dimensions:
L (mm): 234.0
B (mm): 70.0
H (mm): 40.0
Hydrogen AGRU
Hydrogen is a key component of green energy, serving as an energy storage, fuel, and raw material. The electrolysis process for H2 production requires a significant amount of water. In hydrogen projects, seawater is transported via AGRU XXL pipelines to desalination plants, treated with AGRUCHEM, and purified in high-purity PURAD piping systems in ultrapure water plants. In PEM electrolysis, the purified water is directly converted into H2. In alkaline electrolysis (AEM), potassium hydroxide (KOH) is mixed with water and transported from the production site to the electrolysis plant through AGRU fluoropolymer pipes (FEP) or transport tanks (ECTFE). Within the electrolysis plant, the diluted potassium hydroxide is reliably transported or stored in PP tanks and piping systems. The H2 can then be stored in tanks lined with semi-finished products and transported to end customers using the certified AGRULINE H2ready piping system.
AGRU Gas-Lock
The saftey device for your gas system
The AGRU Gas-Lock is the safety valve for applications in gas service pipes. It is implemented in polyethylene fittings (e.g. tapping tees) which
are used for connection pipes. The Gas-Lock closes the passage in case the flow rate exceeds a defined level within a split of seconds. As a
result, there is no leakage of gas and the environment is kept safe. After the repair work has been finished, the Gas-Lock can be re-opened
by reapplying a pressure balance between the supply pipe and the main pipe.
New AGRU PVDF Sheets
AGRU PVDF sheets now availalbe in stock
AGRU is now able to offer PVDF natural sheets with dimension 2000 x 1000 mm. Additionally, fabric backed PVDF PGW (Polyester fabric backed) sheets can be offered as sheets and rolls.

SureAMID
High pressure gas piping system made from polyamide
SureAMID ist ein Polyamid-Komplettsystem, bestehend aus Rohren, Formteilen und der optimalen Verbindungstechnik. Der hochwertige Kunststoff Polyamid verleiht dem System eine hohe Druck- und Spannungsrissbeständigkeit sowie Diffusionsdichtheit.
This makes SureAMID your first choice for high-pressure gas applications up to 16 bar in accordance with DVGW bulletin G 472. The pipes and fittings can be joined using butt or electrofusion welding.
PVDF-UHP tee, reduced
OD 90/20 mm to OD 90/63 mm and OD 110/20 mm to OD 110/63 mm
AGRU is constantly improving and expanding its product programme of PVDF-UHP fittings in order to meet the constantly growing requirements for high-purity plastic piping systems. The latest addition is reduced PVDF-UHP tees (code: 35.065). The overall length of the fittings has been reduced to allow for a compact system design and ecological packaging. All reduced tees can be butt+IR and beadlessly welded.

Poly-Flo induction e-socket
The induction e-socket consists of a metal ring which is overmoulded using PE or PP. The ring inductor is an electrical coil that generates a magnetic field. Inductive heating causes the plastic in the welding zone to plasticise and joins the pipe to the e-socket.
Poly-Flo piping system
The Poly-Flo system is an extension of the double containment piping system. The pipes and fittings are manufactured (extruded/compression moulded) in a single step and are fully pressure-resistant.
Welding methods
- Simultaneous welding
- Cascade welding
- Inner pipe: Infrared or butt welding
- Outer pipe: Induction welding
