Description

A kind of steel skeleton PE plastic composite pipe

Technical field

This utility model relates to pipeline, especially relates to a kind of steel skeleton PE plastic composite pipe.

Background technology

Steel-plastic composite pipe is the novel tube being filled with steel skeleton inside a kind of thermoplastic, wherein with polyethylene compound pipe plastic polyethylene for raw material, steel wire winding net uses the widest as the steel skeleton PE plastic composite pipe of the skeleton reinforcement of vinyl tube, because there being high strength steel body to be covered by among continuous thermoplastic plastics, this multiple tube overcomes steel pipe and the respective shortcoming of plastic tube, and maintain steel pipe and the respective advantage of plastic tube, this multiple tube has excellent flexibility, it is adaptable to the buried water supply of distance, Gas pipeline system. at present, steel skeleton PE plastic composite pipe is when pipeline connects, sealed port of butt end processes and mostly adopts end surfaces welded seal, this end face welded seal structure has following point: owing to pipe material inner wall is relatively thin, heat seal strength and reliability are relatively low, it is affected by thermal expansion and contraction, skeleton in tube wall can produce thrust by face seal parts in opposite end, cause that crack occur in end face seal parts and inner tube layer end face weld, end face seal is caused to lose efficacy, medium seal in steel skeleton and plastics in conjunction with in gap, affect the use safety of tubing, pipeline welding simultaneously needs to adopt professional equipment and a large amount of skilled craftsman, consume a large amount of electric power equal energy source simultaneously, increase cost, do not meet economic and environment-friendly production theory. now, having steel skeleton PE plastic composite pipe to adopt Flange joint, but flange used is mostly common flange, when running into moment of torsion effect, contact jaw face seal reduces, it is easy to causes internal flow to leak, pollutes.

Utility model content

For solving above-mentioned technical problem, the purpose of this utility model is in that the deficiency overcoming prior art to exist, it is provided that a kind of steel skeleton PE plastic composite pipe.

This utility model is realized by following technical proposals:

A kind of steel skeleton PE plastic composite pipe, including PE tubing body, steel skeleton, ring flange one and ring flange two;Described steel skeleton is wrapped in PE tubing body, and described ring flange one and ring flange two are outside PE tubing body two ends, and ring flange one is in PE tubing body outer end, and ring flange two is inside ring flange one.

Preferably, described ring flange one is 3-6cm with the spacing of ring flange two time.

Preferably, described ring flange one is provided with coaxial bolt hole one, and ring flange two is provided with bolt hole two, and bolt hole one is coaxial with bolt hole two.

Preferably, described bolt hole one and bolt hole two are preferably 8-12.

Preferably, the surface roughness of described ring flange one is not more than Ra0.6.

Preferably, the end face of described ring flange one is provided with seal groove, supports the use sealing ring, it is achieved end face seal.

Preferably, the end face of described ring flange one is provided with seal groove, it is preferred to 2-5 bar.

The utility model has the advantage of:

1. adopt multiple ring flange, increase pipeline torque resistant ability, riser tubing tip side face seal, it is prevented that fluid leakage;

2. adopt ring flange to connect, it is not necessary to use welding equipment, reduce equipment and put into artificial, save the energy.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Shown in figure: 1 is seal groove, 2 is bolt hole one, and 3 is ring flange one, 4 is steel skeleton for bolt hole two, 5 for ring flange two, 6,7 is PE tubing body, 8 is end face, 9 is pipeline.

Detailed description of the invention

Below in conjunction with Figure of description and embodiment, this utility model is described in detail, but is not limited to this.

As it is shown in figure 1, a kind of steel skeleton PE plastic composite pipe, including PE tubing body 7, steel skeleton 6, ring flange 1 and ring flange 25; Described steel skeleton 6 is wrapped in PE tubing body 7, and described ring flange 1 and ring flange 25 are outside PE tubing body 7 two ends, and ring flange 1 is in PE tubing body 7 outer end, and ring flange 25 is inside ring flange 1; Ring flange 1 is provided with coaxial bolt hole 1, ring flange 25 is provided with bolt hole 24, bolt hole 1 is coaxial with bolt hole 24, bolt hole 1 and bolt hole 24 are preferably 8-12, end face 8 roughness of described ring flange 1 is not more than Ra0.6, the end face 8 of ring flange 1 is provided with seal groove 1, and seal groove 1 quantity is according to caliber and seals pressure, it is preferred to 2-5 bar.

Install in connection procedure at this set steel skeleton PE plastic composite pipe, two adjacent steel skeleton PE plastic composite pipe end faces are relative, install the sealing ring in seal groove 1, end face is adjacent to, the bolt hole 1 of two relative ring flanges 1 is axially aligned, two nuts are positioned over the non-end face side of two ring flanges 1, high-strength bolt is inserted from the bolt hole 24 of a steel skeleton PE plastic composite pipe, bolt hole 24 to another root steel skeleton PE plastic composite pipe, nut is fixedly installed to outside two bolts hole 24, tight a bolt two nuts of the non-end face in hole 1 simultaneously, repeat abovementioned steps, until all bolts have connected, adopt ring flange 25 to assist fixed flange 1, when steel skeleton PE plastic composite pipe rotates moment of torsion, fixing connecting end surface 8 can be assisted, reduce connecting end surface 8 and loosen probability, improve sealing effectiveness, it is prevented that in pipeline 9, fluid is revealed by end face 8.

The above is only preferred implementation of the present utility model, it is noted that this utility model is not limited to aforesaid way, and under the premise without departing from this utility model principle, moreover it is possible to improve further, these improvement also should be regarded as protection domain of the present utility model.
