Spiral Wrap Pre-Formed Silicone Rubber Heaters

Spiral Wrap Heaters- Pre-formed Flexible Silicone Rubber Heater Technology For Small Diameter Rigid & Flexible Pipes & Tubes

NPH silicone spiral wrap heaters to suit pipe work and tubular applications, however, manufacturing techniques for standard preformed heaters meant that for small diameter pipes the heater could only be manufactured in short lengths for rigid pipe work. Through continued product development, NPH can now offerthe Spiral Wrap Heater range to suit flexible or rigid pipes. All in all a great flexible heater strip pre-formed spirally to fit various small diameter pipes/tubes/lines with consistent contact for better temperature uniformity.
