Fixing distances are the same regardless of what the pipework is being fixed to.

Pipework should be insulated and any brackets/clips etc should also be insulated.

not sure about your country but genral standard in uk is 1.5 metres between fixings

Don't tie wrap the pipe to the tray in the riser, as the pipe could slip inside the insulation and cause a probelm with the vapour seal. If you pull the tie to tight it will cause a failure of the insulations integrity.
Best to clip with Insualted HYDRO-ZORBS or CUSH-CLAMPS on channel.
