Abstract
The utility model provides a lining plastic metal composite pipe which is connected with a plastic tube element by making use of sweating soldering, comprising a metallic external layer, and a plastic internal layer which is positioned in the external layer and composite with the metallic external layer. The utility model is characterized in that a plastic bonding portion is arranged on at least one end of the composite pipe. The utility model also has the advantages of beautiful appearance, strong ageing resistance, high superficial hardness, easy operation, low cost, no leakage, and high reliability.
Description
Technical field:
The utility model is relevant with composite pipe, and is relevant with the plastic lining metal composite pipe that adopts sweat soldering to be connected with plastic pipe especially.
Background technique:
The PP-R plastic pipe uvioresistant of selling on the market, ageing resistance is poor, surface hardness is poor, not attractive in appearance.The plastic lining metal composite pipe that uses on the market has overcome the shortcoming of plastic pipe, but with the metal pipe element mechanical connection, need nut, seal ring and snap ring etc., have that execute-in-place requirement height, difficulty are big, a trouble or exist sealing not strong, hidden danger such as seal ring is easily aging.
The model utility content:
The purpose of this utility model is in order to overcome above deficiency, provide a kind of beautiful shape, uvioresistant, ageing resistance strong, the surface hardness height, easy to operate, cost is low, ne-leakage, reliability are high is beneficial to the plastic lining metal composite pipe that sweat soldering is connected with plastic pipe.
The purpose of this utility model is achieved like this:
The utility model plastic lining metal composite pipe comprises metal outer, is positioned at the compound with it inner plastic of metal outer, and it is characterized in that has the plastics joint at least one end of composite pipe.
On above-mentioned composite pipe one end plastics joint is arranged.
On above-mentioned composite pipe two ends plastics joint is arranged.
When the utility model is connected with plastic pipe, other accessory need be installed, but the plastics joint is inserted in the cavity of plastic pipe joint one end, by sweat soldering this multiple tube termination and the melting welding of plastic pipe joint cavity inner wall are integral the ne-leakage point.
The utility model beautiful shape, uvioresistant, ageing resistance are strong, the surface hardness height, with short production cycle, cost is low, and is in light weight, and fitting operation is convenient, and quality is good, and the reliability height is used for plastic pipe sweat soldering ne-leakage, sealing effect good.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 be among Fig. 1 shown in the utility model and plastic pipe connection diagram.
Fig. 3 is another structural representation of the utility model.
Embodiment:
Embodiment 1:
Fig. 1 has provided present embodiment 1 figure.The inner plastic 2 that metal outer made from aluminum alloy material (or carbon steel material or stainless steel material) in tube reducing cold-drawn mode 1 and three type polypropylene PP-R materials (or polythene PE material) are made is closely compound.Plastics joint 3 is arranged on the one end.
As shown in Figure 2, plastics joint 3 is stretched in the plastic pipe 4 joint cavitys, composite pipe plastics joint and the melting welding of joint cavity inner wall are integral by sweat soldering.
Also can make the composite pipe of no plastics joint earlier, at the construction field (site), as required, adopt cutting process that composite pipe is cut into Len req.And then the termination metal outer that the composite pipe of Len req need weld peeled off and form behind the plastics joint 3 again and the plastic pipe sweat soldering.
Embodiment 2:
Fig. 3 has provided present embodiment 2 figure.Present embodiment 2 is basic same with embodiment 1, and not existing together is that the utility model composite pipe two ends all have plastics joint 3.
Claims (3)
1, plastic lining metal composite pipe comprises metal outer, is positioned at the compound with it inner plastic of metal outer, and it is characterized in that has the plastics joint at least one end of composite pipe.
2, plastic lining metal composite pipe as claimed in claim 1 is characterized in that on composite pipe one end plastics joint being arranged.
3, plastic lining metal composite pipe as claimed in claim 1 is characterized in that on composite pipe two ends plastics joint being arranged.
