Subject: Heater pipes...
I'm trying to source new water heater pipe (the ones which run under the car to the rear heater). LDPE pipe, the type used in irrigation systems, is identical in size and look but...
'For common commercial grades of medium- and high-density (M/HDPE) polyethylene the melting point is typically in the range 120 to 130 °C (248 to 266 °F). The melting point for average, commercial, low-density polyethylene (LDPE) is typically 105 to 115 °C (221 to 239 °F).'
I think they would have used something readily available and LDPE would have been, plus it can easily be thermally set to a metal pipe joint... My original pipework has sagged between the retaining clips showing that it has obviously distorted so it suggests LDPE?
Any ideas greatfully recieved!
