Saddle connects.
The negative ion far-infrared antimicrobial antiscale tubing that this utility model is provided can not adopt the socket joint connected mode of binding agent,
Because polyolefin based materials are nonpolar, so far it has not been found that available binding agent can ensure sealing under stress.It is poly-
Olefines pipeline can not be using threaded connection, and threaded connection is close by the compressive stres produced between internal and external threads when tightening
Envelope, because the easy creep of polyolefin produces stress relaxation, cannot keep again sealing after stress relaxation.
In some embodiments, the hot-melt adhesive paste connects selected from melting connection, hot melt spigot-and-socket connection, hot melt saddle
At least one in connecing.
When the negative ion far-infrared antimicrobial antiscale tubing that this utility model is provided adopts melting connection, tubing is put down
Whole end face, with stable pressure pressure on hot plate so as to after melting, remove heating plate, rapidly by two melting faces with forcing
Together, kept for a period of time under a steady pressure, until joint is cooled down.The polyolefin layer be polyethylene, polypropylene with
And can be connected using heat-melting butt-joint mode during polybutene.
Tubing of the nominal outside diameter less than 110mm is preferably using the tubing that hot melt spigot-and-socket connects.
The material of the technological parameters such as the welding procedure temperature of melting connection, welding pressure and time and plastic pipe is special
Property is relevant, can be found in the relevant regulations of each pipeline kind.The welder equipment of melting connection should meet GB/T 20674.1-
2006 regulation.
Hot melt spigot-and-socket connection is to use the TPO inner surface of pipe fitting of the outer surface of TPO tubing and injection mo(u)lding
Stable pressure is pressed on heating tool so as to after melting, removes heating tool, is inserted pipe end with stable pressure rapidly
Enter in pipe fitting bellmouth, kept for a period of time under a steady pressure, until joint is cooled down.
Hot melt saddle carries out the connection of branch line on supervisor when connecting, saddle heating tool is heated saddle pipe simultaneously
The saddle face of part and supervisor's arc face to be connected so as to after melting, remove saddle heating tool, rapidly with stable pressure by saddle
Type pipe fitting is firmly pressed on tubing joint face, is kept for a period of time under a steady pressure, until joint is cooled down.
In some embodiments, the electric smelting is connected as electro-fusion socket connection and/or electric smelting saddle type connection.
Electric smelting connection it is specific be it is easy to connect, rapid, joint quality is good, and the interference of external factor is little, less in bore
Using both economical on pipeline, can be used for the polyolefin pipe or socket pipe fitting company of different type and different melt flow rate
Connect.
Electric smelting connection need to use special electric smelting connection equipment, electric smelting connection equipment meet GB/T20674.2-2006's
Regulation.Electric smelting connection equipment correctly should connect with electric melting pipe fittings, the voltage of electrified regulation and should meet heat time heating time electric smelting connect
Equipment and the regulation of electric melting pipe fittings manufacturing enterprise.Electric smelting connects cooling period, must not mobile link part or the applying on connector
Any external force.
Electro-fusion socket connection is that the electric melting pipe fittings of embedded resistors silk are enclosed within tubing or pipe fitting, electrified regulation electric melting pipe fittings
Inner surface and tubing outer surface so as to melting be connected as a single entity, until joint cool and solidify.
Electric smelting saddle type connection is that the saddle face of electric smelting saddle type pipe fitting is fixed on supervisor's arc face to be connected, by electric melting saddle
The inner surface of the Resistant heating pipe fitting buried in type pipe fitting and supervisor's arc face to be connected so as to which melting is connected as a single entity, Zhi Daojie
Head cooling and solidifying.
In some embodiments, the mechanical type connection connects selected from spigot-and-socket flexible connection, flange, pipe clamp connects,
At least one in steel modeling transit joint connection.
Flange connection is mainly used in TPO pipeline and the pipe fitting such as metallic conduit or valve, effusion meter, pressure gauge
Connection.Flange connects mainly by TPO flange, steel or aluminum lap joint flange, pad or sealing ring, bolt, nut
Deng.By fastening bolt, nut when flange connects, make to be in close contact between flange, reach the purpose being tightly connected.Identical is gathered
Connection between olefin plastics tubing can also be connected using flange, and simply two flanges being connected with each other are polyolefin methods
Orchid, the tubing connection for being typically only used for larger specification or the pipeline for needing dismounting.
The negative ion far-infrared layer of the negative ion far-infrared antimicrobial antiscale tubing that this utility model is provided can be by coating
Obtain.
Melting connection can not be adopted between the negative ion far-infrared antimicrobial antiscale tubing of various criterion size ratio, preferably
Connected using electro-fusion socket.When the tubing is connected with metallic conduit or metallic conduit fittings, it is preferred to use flange connects.
When connecting between pipeline, need using corresponding special fastening means, it is impossible to adopt open firing.When in temperature mistake
When low, such as less than -5 DEG C, or wind speed relatively by force under conditions of heated or during electric smelting attended operation, should take protective measure or
The technological parameter of adjustment connection equipment, such as takes Windproof thermal insulation, pipe end closure or extends the measures such as heat time heating time.
