Green polypropylene pipes are mainly supplied. Propylene is one of the best examples of pipes andpp pipe fitting available; Most of its consumption is related to drinking water pipes.
Polypropylene pipes and fittings, also called green pipes; One of the best and best-selling connections on the market. These pipes have unique advantages and features.
What is polypropylene pipe fitting used for?
Polypropylene pipes can also be used in pressurized piping networks, but their scope is limited to low pressure lines (indoor use, hot and cold sanitary water piping). Today, these pipes are widely used in the transfer of chemicals and sewage systems.
These pipes are classified into three categories, PP-H, P-B and PP-R. These pipes have the lowest density among all the heat pipes. The molecular structure of different types of polypropylene pipes has made their resistance to fluids highly dependent on the type of fluid, whether play or acidity, and the degree of hardness of the fluid, as well as the amount of temperature and environmental conditions. Due to their high resistance to heat conditions, these pipes have been widely used to carry various fluids at certain temperatures.
What is important by the relevant standards is the calculation of the useful life of polypropylene pipe installation systems, which is explained here for a period of 50 years. In a 50-year period, virtually 14 years have passed since this period of water in these pipes with a temperature of about 20 degrees Celsius, because certainly 3.5 months of the year the heating system is off and providing hot water for it does not make sense, and this means 14 years It’s been 50 years. During the same 50-year period, a maximum of 25 years of water passes through pipes with a temperature of 60. C, which is the direction of the water available for bathing. In a maximum of 10 years, the 50-year period of water passes at a temperature of 80 degrees Celsius. Finally, in the 50-year period, water can be passed permanently for one year at a temperature of 90. C, and in the same period 100 hours of water can pass 100. C.

Advantages of polypropylene pipes
No rot inside and out: These pipes do not corrode when exposed to moisture and corrosive substances such as plaster, lime and other building materials.
Low weight: The weight of these pipes is much lower than that of metal pipes due to the polymer nature of their material, so transportation and plumbing operations with these pipes are easier.
Low thermal conductivity: These pipes have a lower thermal conductivity than metal pipes. Therefore, when these pipes are used to transfer hot or cold water, less energy is wasted than metal pipes during fluid movement.
Low pressure drop and sedimentation: Due to the lower roughness of the inner polypropylene pipe pressure rating surface of these pipes, they have less pressure drop and sedimentation than metal pipes.
Quick and easy installation: The light weight and marking line in these pipes and the different angles of the connections have made the installation of these pipes quick. These pipes can withstand a constant temperature of 65. C with a pressure of 20 bar for 50 years. Therefore, these pipes are used only for hot water and cold water sanitation (consumption) and their use is limited for plumbing heating systems.
Longitudinal expansion coefficient: The coefficient of longitudinal expansion of polypropylene pipes is higher than the coefficient of longitudinal expansion of metal pipes. Therefore, it is necessary to use expansion control devices for piping in long straight routes.
Oxygen infiltration into the pipe will exacerbate corrosion in equipment of closed heating systems, in which case the rate of decay in metal systems such as radiators, pumps, valves, metal tanks and hot water production sources connected to such pipes will be high.
