Article Introduction
PVC the main components of pipe fittings are polyvinyl chloride, other components are used to enhance their heat resistance, toughness and ductility. PEX is a flexible tubular piping system that can be connected to compression without glue or heat, metal or plastic insertion fittings or other mechanical methods. PEX flexibility simplifies the operation of water supply lines throughout the house. A simpler installation process reduces labor when replacing PVC piping fittings to install new sanitary ware. so how to connect PEX to it? Let’s talk about it.
What is PVC pipe fitting?
The main component of PVC pipe fittings is polyvinyl chloride, and other components are used to enhance its heat resistance, toughness and ductility. It is very popular among everyone and are very popular and widely used. PVC is a synthetic material that is popular in today’s world and ranks second in the world in the use of synthetic materials. PVC pipe fittings have strong corrosion resistance, easy bonding, low price and hard texture. Pipes are used for drainage, wastewater, chemicals, heating liquids and coolants, food, ultra-pure liquids, mud, gas, compressed air and vacuum systems.
advantage:
Low price: The price of PVC pipe fittings is relatively low, which can significantly reduce project costs.
Good corrosion resistance: PVC pipes can resist the erosion of a variety of chemical substances and are suitable for various corrosive environments.
Good insulation performance: PVC pipe has good insulation properties and is suitable for piping systems around electrical equipment.
Easy installation: PVC pipe is light in weight, easy to install, and the glue connection method is simple and fast.
What is PEX?
PEX pipe, also known as cross-linked polyethylene pipe, is made of polyethylene material, and the linear molecular structure of polyethylene is transformed into a three-dimensional network structure through physical and chemical methods, thereby improving the performance of polyethylene. The main raw material of PEX pipe is HDPE, as well as initiators, cross-linking agents, catalysts and other additives. If there are special requirements, other modifiers can be added. PEX is a relatively new pipe product that is increasingly popular and incorporated into building codes for new and old buildings. PEX is a flexible tubular piping system that is connected to compression, metal or plastic insert fittings or other mechanical methods that do not require glue or heat.
Advantages:
High temperature and cold resistance: PEX pipes have good high temperature and cold resistance, can work stably in a wide temperature range, and are suitable for heating, heating and hot and cold water pipes.
Pressure resistance: PEX pipes have high pressure resistance and can withstand high water pressure, which is suitable for pipe systems that need to withstand high pressure.
Chemical corrosion resistance: PEX pipes have good corrosion resistance to a variety of chemical substances and are suitable for various corrosive environments.
Long service life: PEX pipes have a service life of more than 50 years under normal conditions and have high durability.
How to connect PEX to PVC pipe fittings?
Step 1
Use a hacksaw to cut past areas and remove any damage from the end of the PVC pipe. Slide the rounded edge of the semi-circular document along the inside of the cut PVC until all loose documents have been removed.
Step 2
Apply a uniform PVC primer to the outside of the PVC cutting tube and to the inside of the externally threaded PVC joint. Apply each primed surface with PVC glue. Slide these parts together while twisting the PVC fittings back and forth. Hold the pieces together for 30 to 45 seconds.
Step 3
Wrap the pipe sealing tape around the external threads of the PVC fitting. Make sure that one layer of material covers all the fitting threads.
Step 4
Align the threads of the internally threaded brass PEX adapter with the external threads of the PVC fitting. Turn the connector clockwise by hand until the PVC is tightened. Use a wrench to turn the brass fitting a half turn to lock it in place.
Step 5
Slide the crimp ring to one end of the PEX tube. Push the end of the pipe to the end of the installed brass fitting.
Step 6
Place the crimp ring 1/8 inch from the end of the pipe. Place the jaws of the PEX crimping tool on the raised portion of the crimp ring. Squeeze the handles together and secure the PEX tube to the brass fitting.
Conclusion
PEX pipe fittings are suitable for heating, heating and hot and cold water pipes. Due to their excellent high temperature and cold resistance, they are particularly suitable for occasions that need to withstand large temperature changes. PVC pipe fittings are widely used in drainage, sewage, wire conduit and other fields, as well as building piping projects and water-saving irrigation projects. Due to their low price and easy installation, PVC pipes are a cost-effective choice in many occasions. Therefore, in different application scenarios and usage situations, choose according to the actual situation.
