Pre-insulated Steel Pipe (standart)
Pre-insulated Steel Pipe (standart)
Description
The steel pipes used in the manufacturing of pre-insulated pipes are manufactured longitudinally welded (ERW) or spirally welded (SAW) in accordance with the norms required by the standard TS EN 253 or customer demands. Pipes comprise three basic materials. Carrier pipes are established as steel, copper or plastic based according to the properties of the carried fluids. Casing pipes are manufactured from high density polyethylene (HDPE) raw material, with UV resistance, 100% waterproof and with online corona. PUR ( POLYURETHANE INSULATION MATERIAL) that is injected between the carrier pipe and casing pipe provides heat insulation besides enabling two pipes operating as one pipe by bonding them together.

Pre-insulated stainless steel pipes have higher corrosion resistance and oxidation strength compared to other steel pipes. It has a wide range of use such as the food and dairy industry, maritime industry and chemical industry. The preservation of heat in the lines used in these fields is provided by pre-insulated stainless steel pipes.

In addition to its high conductivity and machinability, due to its suitability for processes such as soldering, welding, etc., and its easy formability, copper pipes have a wide range of use such as sanitary installations, solar energy systems, and air and oil installations. As a standard, we can do insulation on copper pipes between diameters of Ø15 – Ø80, as well as in different diameters upon request.
