Abstract
The utility model discloses a compound tube with a fixed joint. The end of the compound tube is cast to a fixed joint through an injection molding and the fixed joint fully covers the end of the compound tube. The utility model makes the connection of the tube and the fixed joint firm and has a good performance resisting pulling and drawing by adopting injection modeling process and prevents metal materials inside the compound tube profile from rusting. Meanwhile the utility model is easy and convenient to install, thereby reducing the labor consumption and increasing job efficiency.
Description
Technical field
The utility model relates generally to tubing, relates to a kind of composite pipe of fixed joint more specifically.
Background technique
In the prior art, when steel skeleton reinforced plastic (polyethylene) composite pipe is carried out the pipeline connection, must adopt electrical fusion joint to carry out sweat soldering with the dedicated electric-thermal fusing soldering welder by welding.For guaranteeing firm and reliable connection, welding technique requires must be strict.If the excessive or overlong time of Current Control,, make the composite pipe inner layer plastic tube overheated and does not support the swelling pressure that the welding zone polyethylene melts, and inwardly subside because of the electric heating merits and demerits cause the welding area over-heating greatly; If Current Control is too small or the time is not enough, then can cause welding bad again, cause joint and tubing welding anti-pulling poor performance, pipe-line system pressure test generation seepage with take off pipe.So electric heating fusion welding reliability is not enough because of the working stability of welding machine special at present, it is improper to reach being provided with of electric heating joint electric thermal power and electric heating zone length, very easily produce not prison welding, and pipeline junction generation seepage occurs and take off pipe, while electric heating fusion welding complicated operation, difficult control needs very skilled skilled worker to carry out operation, and is not easy to operate.
The model utility content
Technical problem to be solved in the utility model is, a kind of fixed joint composite pipe is provided, make it to reach to be connected firmly, and effect simple to operate.
The technological scheme that technical problem described in the utility model adopted is, a kind of fixed joint composite pipe comprises composite pipe, and the end of described composite pipe is by fixed joint of molding and forming, and described permanent joint all coats the composite pipe end.
Further, described permanent joint is provided with securing means.
Further, described securing means is that flange-type connects, and between the end face of two permanent joints, be provided with rubber gasket, be the hot melten type butt joint between perhaps described permanent joint, by between the end face of two permanent joints, heating plate being set, after the end face heating to two joints, take out heating plate, the welding of pressurizeing, the cooling back realizes that pipeline connects.
The beneficial effects of the utility model are, owing to adopt the technological method of injection moulding, the end of composite pipe by fixed joint of molding and forming, are made to be connected firmly between tubing and permanent joint that the anti-pulling performance is good.And permanent joint all coats the composite pipe end, prevents that composite pipe interior metal material from getting rusty, thereby has reduced the independent treatment step that composite pipe section metal is coated, and has improved working efficiency.In addition, adopt traditional flange-type to connect or the hot melt butt joint, make to connect reliably good seal performance between permanent joint.

Embodiment
As shown in Figure 1, adopt the technological method of injection moulding, with fixed joint 3 of end molding and forming of composite pipe 4.With after the heating of composite pipe 4 ends, be positioned in the injection mould before the moulding, the core of mould is installed on composite pipe 4 inwalls behind the matched moulds, by injection, pressurize, cooling forming permanent joint 3.And permanent joint 3 all coats composite pipe 4 ends.
As shown in Figure 2, adopt flange-type to dock mutually at the permanent joint end of composite pipe 4, between the end face of two permanent joints 3, place rubber gasket 1, be set in activity steel flanges 2 on the permanent joint 3 of composite pipe 4, pass circular hole on the flange 2 with clamping bolt 5 again, then packing ring 7 and nut 8 are enclosed within the silk mouthful end of clamping bolt 5, connect steel flanges 2 fastening by nut 8, make rubber gasket 1 compressive strain, realize connecting sealing.
Embodiment 2
As shown in Figure 3, the flange of conveying equipment for fluid substances, valve or other pipe-line systems 6 of the permanent joint end of composite pipe 4 and flange join type is connected, again steel flanges 2 is sleeved on the permanent joint 3 of composite pipe 4, between the end face of permanent joint 3, place rubber gasket 1, the flange of steel flanges 2 with equipment, valve or other pipelines is fastenedly connected by nut 8 with clamping bolt 5 then, make rubber gasket 1 compressive strain, realize being tightly connected.
As shown in Figure 4, permanent joint end face to composite pipe 4 adopts hot melten type to dock mutually, between the end face of two permanent joints 3, place the heating plate of polyvinyl piping materials hot melt butt joint special device, after the end face of both sides permanent joint 3 heated, take out heating plate then, whole permanent joint is pressurizeed, make the end face mutual extrusion welding of the permanent joint 3 after the heating, the cooling back realizes that pipeline connects.
Claims (5)
1. a fixed joint composite pipe comprises composite pipe (4), it is characterized in that, the end of described composite pipe (4) is by a permanent joint of molding and forming (3), and described joint (3) all coats the end of composite pipe (4).
2. fixed joint composite pipe according to claim 1 is characterized in that, described permanent joint (3) is provided with securing means.
3. fixed joint composite pipe according to claim 2 is characterized in that, described securing means is that flange-type connects.
