Pre-Insulated TubingUTC Pre-Insulated tubing is designed for the applications where a minimum heat loss isrequested. This product provides a solution for maintaining a stable temperature alongthe line with a minimum preserved energy. The maintenance of applications such assteam supply and condensate return takes much installation time, shut off lines in thejobsite and in many cases loss of productivity and profits. The solution is a thermallyprotection on the line by the usage of Pre-Insulated tubing.It is highly recommended to be used where ambient temperature tends to vary betweenday to night and in cases where it drops down to freeze conditions. The Pre-Insulatedtube also protects the personnel from contacting directly with the high temperaturelines and contributes to the safety working environment. The usage of the Pre-Insulatedtubing contributes to a clean environment where less energy is consumed.Features1. 1/4 to 1/2 in. and 6 to 12 mm tubing sizes available in 316/316L Stainless Steel and Copper.2. Seamless , welded tubing and set tube stick available in Stainless Steel3. Jacketing materials available: TPU and PVC other materials available on customer request4. Pre-Insulated tube, contributes to the personnel safety5. Light and easy for installation6.
