          What is PP-R pipe fittings?
           

           

          PP-R fittings are accessories used to connect PP-R pipes, including elbows, tees, tees, caps, plugs, etc. PP-R fittings are mainly used for changing the direction of pipelines, connecting pipelines, changing the direction of fluids, and sealing reserved pipes. The clamps, high clamps, and low clamps of PP-R fittings are used to fix pipelines, while PPR Yuanbaowan and winding bends are used for the bypass connection of intersecting pipelines.

           Materials of Construction

          PPR pipe is a pipe made of randomly copolymerized polypropylene. The material of PPR pipe is random copolymer polypropylene, which is a thermoplastic with excellent heat resistance, pressure resistance, corrosion resistance, and flowability. PPR pipes are shaped through special molds. During the melting and extrusion process, the raw materials are heated to a certain temperature, and then cooled and cut to ensure their final physical properties and dimensional accuracy.

          The use of PPR pipes

           

           
           

          Building water supply and drainage

          PPR pipes are suitable for the cold and hot water systems of buildings, including centralized heating systems; Heating systems inside buildings, including floors, wall panels, and radiant heating systems; Directly drinkable purified water supply system; Central (centralized) air conditioning system.

           
           
           

          Industrial use

          PPR pipes can be used in industrial piping systems for transporting or discharging chemical media.

           

          Agricultural irrigation

           

          In the field of agriculture, PPR pipes are used in irrigation systems to help farmers utilize water resources more effectively.

           
           
           

          In the municipal field

          PPR pipelines are used for infrastructure construction such as urban gas, electricity, and fiber optic cable sheaths.

           

          Other fields

          PPR pipelines are also used in industries such as healthcare, laboratories, food processing, as well as water supply systems for mobile facilities such as ships and vehicles.

           

           

          Characteristics of PP-R pipe

           

          1. Non toxic and hygienic: The raw material molecules of PPR pipes are only carbon and hydrogen elements, and there are no harmful or toxic elements present. They are hygienic and reliable, and can be used not only for cold and hot water pipelines, but also for pure drinking water systems.
          2. Insulation and energy saving: The thermal conductivity of PPR pipe is 0.21w/mk, which is only 1/200 of that of steel pipe.
          3. Good heat resistance: The Vicat softening point of PPR pipe is 131.5 ℃. The maximum working temperature can reach 95 ℃, which can meet the requirements for the use of hot water systems in building water supply and drainage regulations.
          4. Long service life: PPR pipes can have a service life of more than 50 years under the conditions of working temperature of 70 ℃ and working pressure (P.N) of 1.0MPa (provided that the pipe material must be S3.2 and S2.5 series or above); At room temperature (20 ℃), the service life can reach over 100 years.
          5. Easy installation and reliable connection: PPR pipes have good welding performance, and the pipes and fittings can be connected by hot melt and electric melt, making installation convenient and the joints reliable. The strength of the connection part is greater than that of the pipe itself.
          6. Recyclable materials: PPR pipe waste is cleaned, crushed, and recycled for the production of pipes and fittings. The amount of recycled materials shall not exceed 10% of the total amount and shall not affect the quality of the product.
          7. Chemical corrosion resistance: eliminates the worry of pipeline scaling and yellow rust on sinks and bathtubs.
          8. Lightweight: Only one eighth the weight of metal pipes, easy to transport, and low construction intensity.
          9. Beautiful appearance: The product has smooth inner and outer walls, low fluid resistance, soft color, and beautiful appearance.
          10. Can be buried underground: The position of the pipe can be detected by a metal detector.
          11. Easy and reliable installation: using hot melt connection, no need for threading, a joint connection can be completed in seconds. High quality copper inserts are used to connect with metal pipes and water separators, ensuring safety and reliability.
