Stainless workshop.
We manufacture.

Manifolds, borehole heads, rising mains, analyser plates, special pipework. We manufacture in our workshops to your drawings or our specifications, in epoxy-coated steel, in 304L stainless steel for standard use and 316L for saltier or more demanding environments.

01 — Manifolds, fittings & special pipework

Stainless assemblies for pumping stations, treatment units and hydraulic networks.

Suction and discharge manifolds, special pipework, reducers, elbows, threaded outlets, branches and standard flanges: WAP delivers stainless assemblies adapted to pumping stations, treatment units and hydraulic networks.

Manufacturing can be done to client drawings or to WAP specifications, in epoxy-coated steel or in 304L or 316L stainless depending on environment, water quality and operating constraints. Each assembly can be inspected before shipment: dimensions, welds, passivation, hydraulic test and technical file.

  • Suction and discharge manifolds
  • Reducers, elbows, flanges, branches and threaded outlets
  • 304L or 316L stainless depending on environment
  • Manufacturing to client drawings or WAP specifications
  • Dimensional inspection, passivation, hydraulic test
  • Technical file: material certificates, welding reports, test report

02 — Borehole heads & rising mains

Deep boreholes, submersible pumps. WAP delivers.

Deep borehole, submersible pump, rising main, flanged, threaded or quick-pin connection: WAP delivers. We supply stainless borehole heads, rising mains, supports and the hydraulic adapter parts needed for site assembly and operation.

Each fabrication is defined according to the pump, the depth, the borehole diameter, the type of connection and the operating constraints.

  • Custom stainless borehole heads
  • Flanged rising mains
  • Threaded rising mains
  • Quick-pin couplings
  • Supports and adapter flanges
  • Hydraulic parts between submersible pump and rising main
  • Adaptation to pump type, depth and borehole diameter
  • Manufacturing to site constraints and operating conditions

03 — Analyser plates, skids & assemblies

Pre-assembled plates — analysis, dosing, regulation.

For your projects, WAP can supply pre-assembled analyser plates, dosing skids and measurement panels. Goal: reduce on-site assembly time, secure the connections and deliver a clearer solution for operating teams.

pH, chlorine, turbidity, conductivity, pressure, flow, dosing, regulation: each assembly is prepared according to the process, the chosen instruments and the maintenance constraints. Plates can be wired, hooked up, tested and labelled before shipment.

  • In-line analyser plates
  • Dosing and regulation skids
  • pH, chlorine, turbidity, conductivity panels
  • Multi-plate assemblies for full plants
  • Pre-assembly, labelling, prepared connections
  • Workshop tests before departure when in scope
  • Easier on-site commissioning

Less improvisation at assembly. More clarity at operation.

Our welding method

Stainless steel or epoxy-coated steel. A fabrication must arrive operable, not just finished.

Welding, controls
and technical file.

Before shipment,
the inspection that makes the fabrication operable.

A stainless fabrication must arrive operable, not just finished. Before shipment, WAP can organise the necessary checks: dimensions, welds, passivation, hydraulic test, preparation photos and technical file.

Qualified welding processes, chemical passivation of the welds, hydraulic test at proof pressure. Each piece ships with its technical file — material certificates, welding reports, test report.

  • Dimensional inspection
  • Visual weld inspection
  • Chemical passivation of welds
  • Hydraulic test at proof pressure if required
  • Pre-departure photos
  • Material certificates
  • Welding reports
  • Test report
