Quick answer

Specify Ridgeline where the project benefits from corrugated 316L stainless steel tube, long continuous runs, fewer fittings behind walls, and one system covering hot water, cold water, heating and heat-pump pipework.

A good specification should define the application, tube size, fitting system, insulation, support, protection, approvals, installation instructions and required technical documents.

Step 1: Define The Application

Start by identifying the role of each run:

  • hot water distribution
  • cold water distribution
  • central heating flow and return
  • air source heat pump flow and return
  • plant room or cylinder connections
  • underfloor heating
  • final connections through Flexis

Do not specify by material alone. Specify by application and system role.

Step 2: Select The Tube And Size

Use the Ridgeline data sheets and technical support to choose the correct size for the flow requirement, pressure drop, route length and temperature.

For heat-pump applications, sizing should be checked against the heat-pump design. Heat pumps often need careful flow-rate and pressure-drop control.

Step 3: Define The Connection System

Ridgeline tube works with dedicated Ridgeline connection technology. The specification should state the fitting system and any compatibility requirements clearly.

Avoid vague language such as "connect to suit". It invites substitutions and creates confusion on site.

Step 4: Control Hidden Fittings

Where pipework is concealed, specify continuous runs where practical and keep connections accessible where possible.

Suggested wording:

Concealed pipe routes should use continuous Ridgeline 316L stainless steel tube runs where practical, with fittings located in accessible zones unless the manufacturer's instructions and project design permit otherwise.

Step 5: Include Proof Documents

Every specification should link to:

  • product data sheet
  • installation instructions
  • approval certificates
  • pressure and temperature data
  • fitting compatibility guidance
  • warranty information

This helps contractors price accurately and avoids substitution by assumption.

Specification Resources And Project Evidence

The specifier resource page brings together project support and the route to samples. Download the current certificates and data sheets, and review the published Circle Square and Vulcan applications alongside your own design requirements.

Keep A Checkable Design Record

Record the application, selected tube and fitting system, design flow, operating conditions, full flow-and-return length and source-document revisions. Keep unresolved design inputs visible for the project designer to confirm.

The published tube-loss reference provides selected P1 data-sheet rows, units and downloadable source data. It is a manufacturer reference, not an independent test or a complete circuit calculation. Confirm applicability to the fluid and temperature before design use, and include the losses of fittings, valves and equipment separately.

Use the concealed-joint comparison worksheet with the actual fitting schedules. Its downloadable record counts connection interfaces and carries a design checklist. The count does not establish leak probability, hydraulic performance or savings.
