Abstract
A pipe heat transfer assembly adapted to be easily and rapidly installed with unskilled in the field on a pipe to be heated or cooled includes an elongated rigid channel cover member and a separate elongated, preshaped, solid, flexible strip of thermoplastic resin heat transfer material having a first surface preshaped to conform closely to the inner cavity surface of the channel member and a second surface preshaped to conform closely to the shape of the pipe surface on which it is to be mounted. The strip of heat transfer material may be pre-shaped by molding or extruding. An elongated heat transfer element, which may be an electric heating wire or an elongated tube for a heat transfer liquid to flow therethrough, is embedded in the strip during such pre-shaping. Alternatively, a space for reception of the heat transfer element can be formed in the strip during the pre-shaping of the strip and the element subsequently installed in the space. The thermoplastic heat transfer material after preshaping remains solid and flexible without any significant flow within the temperature range of from about 10.degree.F to about 120.degree.F.
