2, pyrocondensation belt connects
The pyrocondensation belt series of products are to design for the anticorrosion and utilidor insulation repaired mouth that reaches built on stilts steel pipe weld bond with burying.It is composited by irradiated crosslinked polyalkene base material and extraordinary seal hot melting glue, can form good bonding with steel tube surface and solids epoxy coating.When the WK-WSS shrink belt is installed in heating, base material is in the simultaneously inner composite layer fusing of radial contraction, hard-pressed bale overlays on the repaired mouth place, has formed firm anticorrosion body with base material outside pipeline, has excellent wear-resistant, corrosion-resistant, shock resistance and good uvioresistant and photooxidation aging property.Pyrocondensation belt is called kink in industry in addition, except the pyrocondensation belt main body, also is furnished with adhesive tape and stator, and pyrocondensation belt is convenient to large-scale production, and construction is also convenient a lot.But the pyrocondensation belt connection is had relatively high expectations to material, must heating install, and causes construction cost also high.
3, hot melt connects
Hot melt is connected with hot melt butt joint connection, hot melt spigot-and-socket connects and is connected with hot melt saddle type.HDPE double-wall corrugated pipe DN≤adopted the injection moulding hot melt spigot-and-socket to connect usually at 63 o'clock; Adopting the hot melt butt joint to connect or the electric smelting socket joint connects more the DN 〉=75 o'clock.
(1) the hot melt butt joint connects
For DN＜63mm or wall thickness δ＜6mm or melt flow rate (MFR) differs big and welding ends ministerial standard size than or different polyvinyl piping materials or the pipe fittings of wall thickness, do not recommend to use the hot melt butt joint to connect; When polyvinyl piping materials that melt flow rate (MFR) is more or less the same or pipe fitting adopt the hot melt butt joint, should in time adjust heating-up temperature, welding pressure, weld time, and carry out hot strength, hydrostatic intensity and explosion bulge test check, meet the requirements and to use.
The hot melt butt joint connects temperature usually between 200～235 ℃, require facility can satisfy following the requirement: energy operate as normal in-10～40 ℃ of scopes, welding machine can guarantee that the heating panel card evenly applies high temperature resistant adherent layer switching time, and pipe clamp centering, frame axial alignment all have certain requirement.
(2) hot melt spigot-and-socket connects
The pipeline of DN＜125mm can adopt manual or mechanical hot melt spigot-and-socket to connect; In recent years, in the urban water supply polyethylene pipe, use this method fewer and feweri, and in the building water supply polyethylene pipe, use comparatively general.
Hot melt spigot-and-socket connects fusion temp and is generally 260 ± 10 ℃.The requirement that hot melt spigot-and-socket is connected facility has: the ring heater surface should evenly apply high temperature resistant adherent layer, can effectively transmit heat between heating panel and ring heater, mechanical welding machine also should be able to guarantee the straightness accuracy of joint and connect before can make the bell and spigot fourth contact.
(3) electric heating is molten connects
The electric heating of Chu Xianing is molten in recent years connects, and construction equipment is electric heating fusing soldering welder and butt fusion welding machine, and welding equipment should meet the requirement of ISO12176-1 or ISO12176-2.
The advantage of electric smelting is that the tubing that is adapted to all different sizes, the different trade mark, unlike material is connected with tubing with tubing, pipe fitting, be not subject to the extraneous factor influence, equipment investment and maintenance cost are low, and be simple to operate, it is smooth that inner-walls of duct keeps, weld bond reliability height.But its deficiency is special-purpose electric melting pipe fittings expense height, the special-purpose bar code difference of different brands pipe fitting, and welding machine is incompatible, and service efficiency is low.
In sum, different methods of attachment respectively have its pluses and minuses.The applicant is devoted to seek a kind of interface of realizing and connects the interface method of the HDPE double-wall corrugated pipe reliable, that operation is simple, cost is also low relatively.
