Overview

  • Includes 4 fittings to make on to each pipe end to form a BSP female nut connection
  • Pre-installed integral temperature sensor cable in four core heavy duty format
  • Annular pipe uses a corrugated design
  • Flexibility and pre-insulated finish saves time and money on solar installations
  • Work temp. - 175ºC (Peak temp. - 190ºC)

Annular pipe uses a corrugated design and its flexibility and pre-insulated finish saves time and money on installations. The pipe packs are designed specifically for solar systems. Each pack comes complete with 4 fittings to form a BSP female nut connection.

The twin pre-insulated pipe also has an integral temperature sensor cable in four core heavy duty format. The extremely high temperatures, difficult sets and bends required and installation time dictate that the use of copper tube with traditional soft solder joints is not an appropriate approach to solar heating systems.

The generally accepted method is to use a flexible, high temperature stainless steel pipe system. This can be used to enter the internal roof space to accommodate an easier connection to the copper flow and returns, or carry the fluid medium direct to the pump station (by far the easiest and most efficient method).

The most common used of these is the annular design which has a series of parallel corrugations giving it its flexibility. A tool to simply create the flange face by crushing a series of the corrugations is available.

The other benefit is that a range of fittings can be used if necessary to make connections between the pipes, and eliminate the requirement for welded joints.

A one piece pipe run between the collector and the pump station removes the risk of leaks, either at time of installation, or later, when pipework has settled or undergone system expansion and contraction.

The pipe can be supplied in coils, or in pre-insulated twin pipe packs to set lengths. Being pre-insulated also offers other benefits, which can only be appreciated by those who have spent frustrating hours labouring on pushing metres of pipe through long lengths of this specially designed lagging which is specified for solar installations.

The annular pipe is made from annealed stainless steel grade 316 and 304, which reduces the amount of springiness in the pipe, making accurate and neat pipework installations easy.
