Pre-insulated Copper Pipes

Ductile cast iron pipe is a pipe type preferred in main transmission lines since it has superior properties such as corrosion strength and abrasion resistance as it is made of cast iron, as well as being able to stretch without deformation. In regions where the temperature is low, freezing frequently occurs on the main transmission lines, especially in winter. Such problems can be avoided by using pre-insulated ductile iron pipes.

The maximum temperature strength of standard type pre-insulated pipes is 140 °C. For this reason, rock wool reinforced (industrial type) pre-insulated seamless steel pipes must be used in lines that are required to operate at higher temperatures such as hot water, hot oil and steam lines.

GRE and GRP pipes have advantages such as lightness, corrosion resistance, high pressure strength, and they are manufactured as pre-insulated under the brand of Yalcın Boru. GRE (Glass Reinforced Epoxy) Pipe GRE pipe is resistant to the abrasive effects of caustic substances and acid concentrations due to its chemical composition. For this reason, it is used in fire, drinking water and cooling water transmission lines, power plants and industrial waste water systems. GRP (Glass Reinforced Polyester) Pipe GRP pipe is a type of pipe that does not corrode, has insulating feature and can operate in a wide range of pH. Drinking water and clean water transmission lines, piping lines of chemical plants and circulation lines of power plants are among the prominent areas of use of these pipes.

Galvanised steel pipes, which are resistant to and all kinds of wear such as corrosion etc. compared to black pipes, are manufactured as pre-insulated to prevent heat loss when used in service water installations, fire hydrant lines and boiler lines.
