It is provided with and enables to the most interstitial blast resistance construction, described metal net layer
Outside is coated with establishment stratum reticulare, is provided with outer tube, described volume outside described establishment stratum reticulare
Stratum reticulare processed is fixing with the inwall of outer tube to be connected.
In above-mentioned novel PE combustion gas tubes, described blast resistance construction is uniformly to divide
It is distributed in the bulge-structure of outer wall of inner tube, the protruding end of described bulge-structure and metal net layer
Contact, between both sides and the metal net layer of described bulge-structure, form space.
In above-mentioned novel PE combustion gas tubes, described bulge-structure is dome-type
Projection, the radius that the mesh radius of described metal net layer is protruding less than dome-type.
In above-mentioned novel PE combustion gas tubes, described establishment stratum reticulare is by high intensity
Fiber establishment is formed, and described establishment stratum reticulare is connected by viscose and outer tube wall are fixing.
In above-mentioned novel PE combustion gas tubes, the inwall of described inner tube is coated with
Flame-retardant layer.
Compared with prior art, the utility model has the advantage of: by outside inner tube
Layer adds metal net layer and establishment stratum reticulare, and establishment stratum reticulare is fixed in outer tube by viscose
Wall, establishment stratum reticulare shape is fixed, and is effectively increased the bulk strength of tubing, it is possible to bear
Bigger pressure, in addition shape between bulge-structure both sides and the metal net layer on outer wall of inner tube
Become space so that there is between inner tube and outer tube certain elastic deformation space, can prevent
Interior pipe explosion.

Detailed description of the invention
As shown in Figure 1 and Figure 2, this programme includes that body 1, the two ends of body 1 set respectively
There is connection end 11, connection end 11 coordinates connecting portion 2, connecting portion 2 are installed
For the connection end 11 of two bodys 1 is integrally connected, in connecting portion 2 inwall
Portion is provided with the annular protrusion 3 with positioning function, is embedded with sealing ring 4 in annular protrusion 3,
The thickness of sealing ring 4, equal to the thickness of annular protrusion 3, sealing ring 4 offers ventilation
Hole 41, two connection ends 11 that two bodys 1 are adjacent support respectively is located at sealing ring 4
Both sides, body 1 includes inner tube 5, is provided with and can increase inner tube 5 machine outside inner tube 5
The metal net layer 6 of tool intensity, is provided with between metal net layer 6 and inner tube 5 and enables to two
Forming the blast resistance construction in space 91 between person, the outside of metal net layer 6 is coated with establishment net
Layer 7, is provided with outer tube 8 outside establishment stratum reticulare 7, establishment stratum reticulare 7 is solid with the inwall of outer tube 8
Fixed connection.
Specifically, blast resistance construction is the bulge-structure 9 being uniformly distributed in inner tube 5 outer wall,
The protruding end of bulge-structure 9 contacts with metal net layer 6, the both sides of bulge-structure 9 with
Space 91 is formed between metal net layer 6.
Saying further, bulge-structure 9 is that dome-type is protruding, the grid of metal net layer 6
The radius that radius is protruding less than dome-type.
Specifically, establishment stratum reticulare 7 is formed by high strength fibre establishment, works out stratum reticulare 7
Being connected by viscose and outer tube 8 inwall are fixing, the inwall of inner tube 5 is coated with flame-retardant layer 51.
Installing for convenience, connection end 11 is provided with external screw thread 11a, and connecting portion 2 leads to
Cross female thread and coordinate installation with the external screw thread 11a on connection end 11.
Specifically, annular protrusion 3 offers annular groove 31, sealing ring 4 sets
There is the bulge loop 42 being embedded in annular groove 31.The both sides of sealing ring 4 are equipped with outwards
