Fitting

A fitting joins two parts of a system: pipes, hoses, valves or equipment. This family covers hose tails, elbows, nipples, reducers, unions, sockets, tees, plugs and special fittings, from DN6 to DN500.

The first criterion is the jointing method:

  • threaded, in brass, bronze or stainless steel: a parallel ISO 228-1 thread does not seal by itself, a gasket does; an EN 10226-1 thread (the European version of ISO 7-1) is designed to seal on the thread; Guidi data sheets state the thread of each part;
  • press-fit, in stainless steel or 90/10 copper-nickel, with an M press profile; FKM seal and 16 bar maximum for the copper-nickel fittings, according to their data sheet;
  • butt-weld, in P265GH / A234 WPB steel, 316 stainless steel or 90/10 copper-nickel;
  • socket fusion, in Aquatherm PPR;
  • push-fit, with John Guest Speedfit fittings, fitted without tools.

The second criterion is the material. Below the waterline in seawater, the site's configurator recommends bronze or stainless steel. 90/10 copper-nickel is used for seawater piping because it resists both seawater corrosion and biofouling. The P265GH steel of the butt-weld fittings is stated to EN 10253-2, the standard for butt-welding fittings for pressure purposes.

Certificates stated on the data sheets, depending on the model: RINA, Lloyd's, 3.1 and 3.2. Brands: RPM, Guidi, Aquatherm and John Guest.
