Threaded plastic pipe fittings refer to plastic pipe fittings with threads, which are used in pipe systems for connection, control, direction change, diversion, sealing, support, etc. These pipe fittings are connected to other pipe components through threaded connections, thereby realizing the construction and expansion of pipe systems.
What are the functions of threaded plastic pipe fittings?
The basic functions and uses of threaded pipe fittings, whether they are made of plastic or other materials, are similar. They are usually used to connect threaded pipe ends to form pipelines, such as water and gas pipes, small-diameter water pipes, compressed air pipes, and low-pressure steam pipes. By applying appropriate adhesive on the threads, the sealing can be ensured to prevent leakage. In addition, Threaded plastic pipe fittings are also used to change the direction of pipes, connect pipes of different diameters, add pipeline branches, fix pipes, etc. These functions make threaded pipe fittings very useful in various industrial and household applications.
Common Threaded plastic pipe fittings material application
PE (Polyethylene) Threaded pipe fittings: The main features of PE Threaded pipe fittings are light weight, good toughness, good low-temperature resistance, harmlessness, relatively cheap price, and high impact strength, but low compressive and tensile strength. They are usually used for cold water supply pipes, drinking water pipes, rainwater pipes, gas pipelines, industrial corrosion-resistant pipes, etc. PE pipe fittings are suitable for conveying gaseous artificial gas, natural gas, liquefied petroleum gas, etc., and have excellent resistance to most domestic and industrial chemicals.
PVC (Polyvinyl Chloride) Threaded pipe fittings: The advantages of PVC Threaded pipe fittings include good tensile and compressive strength, excellent corrosion resistance, low price, but brittle at low temperatures. They are widely used in water supply and drainage, irrigation, gas supply, exhaust pipes, wire conduits, rainwater pipes, industrial anti-corrosion pipes, etc. in residential life, industry and mining, and agriculture.
PP (polypropylene) Threaded pipe fittings: PP Threaded pipe fittings are characterized by energy saving and material saving, environmental protection, smooth inner walls without scaling, simple construction and maintenance, and long service life. They are generally used for home decoration pipes, divided into hot and cold water pipes, and are widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, electricity and optical cable sheathing, industrial fluid transportation, and other fields. PP pipe fittings are suitable for making high-temperature resistant pipeline systems due to their good heat resistance and acid and alkali corrosion resistance.
How to choose suitable pipe fittings?
1. Material selection: Plastic materials with good mechanical properties and corrosion resistance should be selected, such as high-density polyethylene (HDPE), polyvinyl chloride (PVC), etc. These materials can ensure the durability and stability of pipe fittings.
2. Specification matching: Select the appropriate specification according to the pipe diameter and pressure level to be connected to ensure the sealing and stability of the connection. Specification matching is essential to ensure the normal use of pipe fittings.
3. Appearance inspection: Observe whether the thread surface is smooth and has no obvious deformation or cracks to ensure its quality and reliability. Appearance inspection is the first step in evaluating the quality of pipe fittings.
4. Performance considerations: Select plastic threads with good pressure resistance and corrosion resistance to ensure their service life. These performance indicators are directly related to the service life and safety of pipe fittings.
