Here, cross-linking of the molecules is done after the process of extrusion by exposing the pipe to an electron radiation beam. The radiation emitted allows to break the existing links between molecules of the polymer and initiate cross-linking process.Softer than PEX-B.More environmentally-friendly to manufacture.Little or no coil memory. 1, HEWAI provide multilayer pipe as below:GB/T18997 standard, ASTM F 1281/1282 & EN ISO 21003 standard, PEXc-AL-PEXc , PEXc Pipe/Tubing, PE-AL-PEXa Pipe, PEXb-AL-PEXb Pipe, PEXc-AL-PEXc Pipe, PERT-AL-PERT Pipe: Butt/Overlap WeldingPEXb-AL-PEXb Butt WeldingPEXc-AL-PEXc Butt WeldingPE-AL-PEXa Butt/Overlap WeldingPERT-AL-PERTDiameter(mm)Wall Thickness(mm)Diameter(mm)Wall Thickness(mm)Diameter(mm)Wall Thickness(mm)Diameter(mm)Wall Thickness(mm)121.5121.516.62.5121.5162.0162.0202.9162.0202.0202.0253.7202.0252.5252.5324.7252.5262.6262.6  262.6323.0323.0  323.0404.0404.0  404.0505.0505.0  505.0636.5636.5  636.52, Multilayer pipe Introduction:Multilayer pipes are a "composite pipe", which are made of composite materials with a five layers' structure. The inner & outer layers are regularly made of PEX/ PERT (or HDPE) material, middle layer is aluminum core, which is welded in a seamless laser welding technology or overlap welding technology. To bond the PEX layers to aluminum layer, a special adhesive shall be used. This pipe has been widely used for hot & cold water plumbing systems, underfloor heating systems & indoor gas distributions.,etc.3, Difference between butt welding & overlap welding of multilayer pipe:Overlap welding technology is ultrasonic type welding, by using ultrasonic to weld the aluminum in a overlap way.Butt welding technology, also called "seamless butt laser welding", is to weld the aluminum by laser in a seamless butt welding way. By comparison to overlap welded multilayer pipe, the laser welded pipe is considered to be more stable on aluminum welding jointing, especially when the pipe is rounded & beveled by reamer, the multilayer pipe with laser welding is no easy to crack off.From the data of 20+ years of the experience, we note that:customers are mainly using ALPEX/ALPERT 16-32mm pipes for building's cold&hot water system, and radiator heating system.And the customers are preferring ultrasonic overlapped welding PEX-AL-PEX/PERT-AL-PERT/PPR-AL-PPR pipe machine more.We can do:Delivery Terms: FOB,CFR,CIF,EXW,DDP,DDU;Payment Currency:USD,CNY;EUR;Payment Type: T/T,L/C,Credit Card,PayPal,Western Union,Cash,Escrow;Please do not hesitant to contact us:HEWAI ENVIRONMENTAL TECHNOLOGY(Anhui)CO.,LTD
