Pipes
Pressure Resistant Water Plumbing Pipes
Pressure-based plumbing pipes are the most important material of a sanitary installation. At the same time, plumbing pipes should be used in the right place in the right way and the type of pipe to be used should be determined in the most accurate way. For example, while the pipe used for waste water pipes laid underground is different, different pipes are used for the clean water installation where we directly receive the water laid inside the buildings. Natural gas pipes, which are another usage area of the water installation, are of a completely different nature. In terms of heat resistance and tightness, natural gas pipes have different properties compared to others. Pressure-based plumbing pipe has a wide range of products such as galvanised steel pipe, cast iron pipe, brass pipe, copper pipe, steel pipe, plastic pipe. Such a variety should not create a complicated situation. Each of them has different features in terms of its structure and place of use.
