Purpose of PEX Pipe
1.PEX Material Properties
Like PE Pipes, Pex Is Non-Toxic, Odorless, With Good Pressure Resistance, Stability, And Durability. Its Unique Temperature Resistance (-70% Ccn110 ° C) Makes It A Recommended Pipe For Indoor Hot And Cold Water Supply. The Density Of Pex Tube Is 950 Kq/M3。
2.PEX Production Process
The Density of Pex Tube Is 950 Kq/M3. The Production Process of PEX Pipes Is Based On Polyethylene As The Matrix Resin And Silane As The Bond Bridge Material. The Raw Materials Are Fed Into A Specially Designed Reaction Extruder Through A Precision Metering System, And The Vinyl Group of Silane Is Grafted And Formed With Polyethylene In One Step, Forming A Three-Dimensional Molecular Network. This One-Step Production Process Is Currently Widely Used Internationally For The Production Of Variable Link Polyethylene Pipes, And The Production Lines Introduced In China Are Also One-Step Production Processes.
3.PEX connection method and accessories
The connection between PEX pipes adopts copper connectors and fastening rings provided by the manufacturer. The connection between PEX pipes and other metal pipes is not in the form of clamps or sleeves, and special external thread clamps or sleeves are used to connect accessories.
4.PEX Scope of Application
PEX is suitable for indoor hot and cold water supply pipelines. The working pressure of the system is equal to or equal to 0,6Mpa, and the long-term working temperature is less than or equal to 75 ° C (as required by the building water supply and drainage code).
5.PEX production standards
At present, there are not many manufacturers in China that produce PEX pipes, and their production technology is all imported from abroad. The standards used are also based on international standards, and their own enterprise standards are formulated and reported to the local government for approval. There are 7 specifications for the diameter (outer diameter) of PEX pipes, including 16M, 20mm, 25mm, 32mm, 40mm, 501m, and 63mm
