Abstract
The utility model discloses an SPE composite pipe conveying liquid, which has high strength, long service life and good heat insulating performance. Steel ribs (2) with triangular space distance sections are axially and circumferentially distributed in the pipe wall of a cement mortar pipe 1 in equal distribution. 40, the connecting part of two steel ribs is welded to form a steel skeleton in a crossed net shape. An outer layer is a corrosion protecting plastic layer 1 to form the composite pipe.
Description
The utility model relates to a kind of " SPE " composite pipe.
For anticorrosion and insulation, prolong the pipeline spreadable life, mostly adopt composite pipe.Composite pipe is broadly divided into three kinds from structural type, net-shaped steel frame plastic composite pipe, flexible steel skeleton plastic clad pipe, lining inner surface of tubes with plastics pipe (pipe-in-pipe) etc. at present.These composite pipe structures all are steel---two layers of two kinds of materials of plastics are compound, and their bearing capacities are low, and Applicable media is limited in scope, heat resistance difference and easily aging, inner-wall material Hobson's choice.Wherein Steel Skeleton adopts Round Steel Wire boxing formula, and the soldering point area is little, and intensity is low, and bearing capacity is little; Steel-plastic composite pipe, inner tube wall are polyethylene layers, and long-term use back and the easy swelling that produces of oil effect are not suitable for and make the collection oil transport pipeline.
The purpose of this utility model is to avoid the problem that exists in the above-mentioned present technology, and a kind of inside and outside anticorrosion insulation effect and intensity height long-lived " SPE " composite pipe of having concurrently that have is provided.
The purpose of this utility model can reach by the following technical programs: by the composite pipe of slush pipe and protection plastic outer layer; the cross section that is evenly equipped with spacing on axial and circumferential in the slush tube wall is leg-of-mutton reinforcing bar, and two reinforcing bar connecting places weld.
At the two ends of above-mentioned slush pipe around circumferential reinforcing bar closeer, the seamed edge of two reinforcing bars touches mutually, welds in the phase synapsis to connect after pushing.The composite pipe that adopts above-mentioned Steel Skeleton to constitute, solder joint is dark, and surface of contact is big, the intensity height, bearing capacity is strong, can realize its purpose.
The utility model is compared with above-mentioned present technology and had following effect: the utility model is to make the nexine pipe with the slush pipe, and thermal resistance is big, and certain insulation effect is arranged, and is suitable for petroleum pipeline.Adopting the cross section is leg-of-mutton Framework Of Steel Reinforcement, and the axial and circumferential skeleton reinforcing steel bar is welded after pushing mutually, and solder joint is dark, and surface of contact is big, the intensity height, and bearing capacity is strong.Compare with other Steel Skeleton on performance, it is wide to be suitable for the fed sheet of a media scope, can be widely applicable for media such as Oil, Water, Gas; Heat resistance is good, is difficult for aging under the long term high temperature effect.
Accompanying drawing 1 is this composite pipe figure;
Accompanying drawing 2 is Fig. 2 left views;
Accompanying drawing 3 is skeleton drawings in the tube wall of Fig. 1 slush pipe 1;
Accompanying drawing 4 is Fig. 3 left views.
To be further described the utility model below in conjunction with accompanying drawing:
By shown in Figure 1, by the composite pipe that slush pipe 1 and insulating plastic pipe layer 3 constitute, being evenly equipped with the spacing cross section on axial and circumferential in slush pipe 1 tube wall is leg-of-mutton reinforcing bar (2,4), and two reinforcing bars (2,4) intersection connecting place welds.
At the two ends of slush pipe 1 around circumferential reinforcing bar 4 closeer, the seamed edge of two reinforcing bars (2,4) touches the welding of extruding back mutually simultaneously.
Claims (3)
1. " SPE " composite pipe of an output liquid, have slush pipe (1) and insulating plastic pipe skin (3), it is characterized in that: the cross section that is evenly equipped with spacing on axial and circumferential in slush pipe (1) tube wall is leg-of-mutton reinforcing bar (2,4), two reinforcing bars (2,4) connecting place welds.
2. composite pipe according to claim 1 is characterized in that: at the two ends of slush pipe (1) around circumferential reinforcing bar (4) closeer.
3. according to claim 1,2 described composite pipes is characterized in that: the seamed edge of two reinforcing bars (2,4) touches mutually.
