Water Treatment Pipe Systems and Fittings

Durable Pipework Solutions for Industrial Water Treatment

AllWater Technologies supplies a comprehensive range of industrial pipe systems, valves, and fittings designed for reliable, long-term use in water treatment and process applications. Whether you require metric or imperial sizes, chemical-resistant pipework, or specialist fittings for integration into your existing system, we provide the components you need to maintain performance, ensure system integrity, and meet compliance standards.

From treatment plants to bespoke skids, our pipe fittings for water treatment are selected for their proven compatibility, ease of installation, and dependable service life—even in the most demanding industrial environments.

Complete Pipework Packages

Our pipework offering supports all types of water treatment equipment, including reverse osmosis (RO), filtration, chemical dosing, demineralisation, and wastewater systems. We supply pipe, fittings, valves, and accessories as standalone components or as part of a fully specified pipework package for new builds or retrofit projects.

Pipe Types Supplied:

  • uPVC and ABS plastic pipe
    Lightweight, corrosion-resistant, and ideal for low- to medium-pressure applications.
  • Polypropylene (PP) pipework
    High chemical resistance and suitable for aggressive media and elevated temperatures.
  • PE100 and MDPE pipes
    Flexible, robust pipework for buried services and external pipe runs.
  • Stainless steel pipe (304/316)
    Hygienic, pressure-resistant solutions for process-critical applications.
  • Galvanised steel and mild steel
    For structural or general-purpose use where cost efficiency is key.

Each material is offered in a range of diameters and wall thicknesses to meet flow, pressure, and space requirements.

Pipe Fittings for Water Treatment

We stock a complete range of pipe fittings to support connection, transition, and layout flexibility. Our components include:

  • Couplers and adaptors
  • Tees, elbows, and bends
  • Reducers and bushes
  • Unions and flanges
  • End caps and blanking plugs
  • Compression and solvent weld fittings
  • Threaded and push-fit connectors

All fittings are available to match metric and imperial pipework standards, including DIN, BS, and ISO specifications, allowing seamless integration with existing systems or OEM components.

Valve Systems

Valves are a vital part of any pipe system—controlling flow, pressure, direction, and isolation. AllWater offers a range of valve systems for manual and automated control.

Manual Valves

  • Ball valves (uPVC, stainless steel, brass)
    Compact, reliable on/off isolation for clean water and chemical lines.
  • Butterfly valves
    Suitable for larger diameter pipes and higher flows; low pressure drop.
  • Gate valves and globe valves Used where throttling and flow control are required.
  • Diaphragm valves Ideal for dosing systems and applications involving slurry or aggressive media.
Actuated Valves
  • Electric actuated valves Integration-ready for automated systems using 230V, 24V, or 4–20 mA control.
  • Pneumatic valves Fast operation for air-actuated sequences and fail-safe shutoff systems.
Valves are supplied with appropriate flanges, unions, or threaded ends to match your system requirements. ATEX-certified options are also available for hazardous environments.

Metric and Imperial Pipework

We understand that many clients operate mixed systems—especially when upgrading legacy installations or integrating imported equipment. That’s why we supply pipework and fittings in both metric and imperial sizes, with full conversion solutions where required.

  • Metric sizes from 16mm to 500mm (e.g. DIN standard)
  • Imperial sizes from ½” to 12″ (e.g. BS or ASTM standards)
  • Transition fittings to bridge between standards
  • Custom adaptors, flanges, and reducers on request

All components are available with pressure and temperature ratings suited to water treatment applications, including PN10/PN16 and SCH 40/80.

Specialist Pipework Accessories

We also supply a range of accessories and ancillary products to support installation, maintenance, and safe operation:

  • Pipe cutting and chamfering tools
  • Solvent cement and jointing compounds
  • Expansion joints and flexible couplings
  • Pipe tracing and insulation systems
  • Colour-coded tags for chemical lines
  • Drain and vent valves
  • Strainers and flow restrictors

Need a custom skid or pipe assembly? Our fabrication team can supply pre-assembled manifolds, dosing panels, and modular pipe racks ready to install on site.

Technical Specifications

Typical pipe system parameters:

  • Pressure rating: Up to 16 bar depending on material and wall thickness
  • Temperature range: -20°C to +80°C (higher for PP and stainless steel)
  • Pipe sizes: ½” to 12″ (imperial), 16mm to 500mm (metric)
  • Jointing methods: Solvent weld, electrofusion, threaded, flanged, compression
  • Standards: BS, DIN, ISO, ASTM, WRAS-approved components available
