Operating media

Raw waterIrrigation waterWastewaterIndustrial process water

Typical applications

  • Raw water transmission main surge protection
  • Irrigation network pressure management
  • Industrial pipeline surge suppression
  • Pump station water hammer control
  • Wastewater rising main protection
  • Remote or unmanned pump stations (automatic air valve variant)

Coatings

Epoxy internal lining (carbon steel variants)

Approvals

ISO 9001ISO 14001

Features

  • Air cushion in direct contact with pipeline fluid absorbs positive and negative pressure transients caused by pump trip or rapid valve closure
  • Integrated compressor variant maintains air volume on a timed or pressure-actuated cycle, compensating for dissolved air loss over time
  • Automatic air valve variant replenishes air without external power, suited to remote or unmanned installations
  • Carbon steel or stainless steel pressure shell; design per client specification and site hydraulic analysis
  • Capacities from 100 litres to 120,000 litres, sized per transient hydraulic analysis
  • Manufactured to PED 97/23/EC and internationally recognised pressure vessel codes including EN 13445 and ASME VIII-Div.1
  • Bolted inspection manway for internal access

Description

A hydropneumatic surge vessel in which the pressurised air cushion is in direct contact with the pipeline fluid. When pump trip or valve closure causes a pressure transient, the air charge absorbs surge energy and limits pressure wave magnitude. The air volume is maintained either by an integrated compressor on a timed or pressure-actuated cycle, or by an automatic air valve that replenishes dissolved air as the cushion contracts. The open (bladderless) design is suited to raw water, irrigation and industrial applications where direct air-water contact is acceptable. Carbon steel or stainless steel shell, custom-sized from 100 litres to 120,000 litres per hydraulic transient analysis.

Selection notes

This surge vessel is a open type and hydropneumatic pattern, supplied for flanged installation.

Sizes run 100 L to 120000 L.

The body is offered in S275JR, S355JR, P265GH and P295GH, so the grade can be matched to the service rather than the other way round.

Stated service media include raw water, irrigation water, wastewater and industrial process water.

It is catalogued for Water & Wastewater and Industrial Process.

Built to PED 97/23/EC, EN 13445, ASME VIII-Div.1, PD 5500 and CODAP 2000.

Supplier remarks

  • Manufacturer can produce standard tanks up to 120 m³ (120,000 L) and up to 150 bar depending on size and thickness; larger capacities can be examined on request.
  • Water hammer analysis (used to size the vessel) requires: pipe profile, inner diameter, thickness and material, total flow, pump data (power, rotation speed) and water type. Where the pipe profile is unavailable, total length, start/end heights and the heights/distances of high and low points relative to the pumping station are needed instead; without the pipe profile the sizing is indicative only.
  • Optional visual (sight-glass) or magnetic level indication equipment available for the vessel; specify if required.
  • NDT capability: manufacturer states qualified personnel to conduct and interpret dye penetrant (PT) and radiographic (X-ray/RT) testing; no per-unit test standard or guarantee stated for this product.
