Poly-Flo includes a complete piping system made of PE 100-RC and PPR for the safe transport of hazardous media through groundwater protection areas or in chemical plants with a high hazard potential. The high level of cost-effectiveness and decades of research and development make Poly-Flo a reliable partner. The compactly designed double containment piping system is available in PE 100-RC and PPR materials in dimensions ranging from OD 50/32 mm to 225/160 mm. The pressure ratings can be selected between SDR 17/11 and SDR 33/17.

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 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.
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.
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.
AGRU is the first supplier with an extensive product range of pipes and fittings made from high crack resistant PE 100-RC material! This safes costs during installation, increases the system safety and the service lifetime of the complete piping system.
Furthermore, AGRU PE 100-RC FM approved components achieve the highest pressure ratings of 215 psi / 15 bar (SDR 11) and 250 psi / 17.5 bar (SDR 9). With the AGRU FM approved catalog and comprehensive technical support, AGRU offers a complete program and is your partner from planning to completion of any project where FM approved piping is required for underground fire suppression systems.
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.
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.

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
The problem with flange connections (stub flange/backing ring) is that the loose flange designed for plastic welding backing rings does not fit on a FRP stub flange with regard to the d3 dimension. AGRU has now added a backing ring up to OD 630 mm to its product programme to solve this problem.
