What is a flexible hose?
Flexible hoses are used to transfer a wide range of fluids including gaseous fluids, such as air, steam and gases, and liquids, such as water, oils and chemicals. The hoses function for reciprocation of piping systems, absorption of thermal expansion and vibration and centering of piping.
Do flexible hoses restrict flow?
Any restriction to pipework will reduce the flow , the length of the restriction is immaterial, IT IS A RESTRICTION. Flexible pipes on mains applications may be OK due to higher pressures involved. Anything connected to a tank in the loft should not be restricted if possible.
How flexible is Speedfit pipe?
Speedfit Conduit Pipe is supplied in either 15mm or 22mm in coil lengths of 25m or 50m. The flexible convoluted pipe has an outside diameter of 24mm and 30mm.

Do flexi hoses reduce pressure?
5 Answers. There is no difference once the flow is stabilized. But the hose can’t stretch indefinitely – at certain point its tension offsets the pressure , amounts of flow stabilize, pressure and flow rate at outlet rise, and the situation becomes equivalent to rigid hose in all respects.
