Abstract
The utility model discloses a natural gas pipe comprising a pipe body. The pipe body includes a PVC inner layer, a PPE middle layer and a stainless steel ribbon outer layer from inside to outside. Both ends of the pipe body are provided with standard connectors provided with seal gaskets; each standard connector comprises a connector body and a screw cap; a compressing sleeve is riveted at each connector body on the stainless steel ribbon outer layer. The PVC inner layer is made of high-quality PVC; the PPE middle layer is made of high-quality PPE; accordingly, the natural gas pipe has the advantages of acid resistance, corrosion resistance, oxidation resistance, aging resistance, long service life, good tightness, higher safety and the like. The stainless steel ribbon outer layer is made of stainless steel ribbons for covering, the pipe body is protected from abrasion when penetrating a wall, the pipe body is protected from being broken, and the pipe body is also protected from damage when tensioned, deformed and thinned. The compressing sleeves are added, strength of connection between the standard connectors and the pipe body is enhanced, and the standard connectors and the pipe body rarely loosen. The seal gaskets are added to the connector bodies, and tightness is ensured. The natural gas pipe is made of the PVC and PPE, and metal materials are greatly saved. The utility model belongs to the technical field of pipes.
Description
Technical field
The utility model belongs to tubing technical field, specifically a kind of acid-resistance, corrosion protection, anti-oxidant, aging-resistant, long natural gas tube of life-span.
Background technique
Rock gas, is a kind of multi-component mixed gaseous fossil fuel, and main component is alkane, and wherein methane accounts for the overwhelming majority, separately has a small amount of ethane, propane and butane.It is mainly present in oil field, gas field, coal seam and rammell.After combustion of natural gas, without waste residue, waste water, produce, comparing coal, oil equal energy source has the advantages such as the safety of use, calorific value are high, clean.
Existing for connecting the natural gas tube of gas pipe line, employing be that bimetal pipe system becomes, manufacture cost is high, not soft, connection part sealing is poor, and gas leak phenomenon occurs often, has potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of acid-resistance, corrosion protection, anti-oxidant, aging-resistant, life-span length, good airproof performance, safer natural gas tube are provided.
Technical solution adopted in the utility model is: a kind of natural gas tube, comprise body, and body comprises that PVC internal layer, PPE middle level and stainless steel silk ribbon are outer from inside to outside; Body two ends are equipped with modular connection, and joint is provided with sealing gasket; Modular connection comprises joint and bolt-joint cap, and on the stainless steel silk ribbon skin of joint, riveting has clamping sleeve.
The beneficial effects of the utility model are: a kind of natural gas tube of the utility model, adopt high-quality PVC material as internal layer and high-quality PPE material as middle level, acid-resistance, corrosion protection, anti-oxidant, aging-resistant, life-span length, good airproof performance, the advantage such as safer; The outer stainless steel silk ribbon parcel that adopts, protection body is avoided wearing and tearing when through body of wall, prevents that body from being staved, and while also preventing body because of tensile buckling attenuation, damages; The increase of clamping sleeve, has strengthened the join strength of modular connection and body, guarantees both difficult drop-offs, the setting of joint sealing gasket, and later stage installation is difficult for dropping, and has strengthened sealability.The utility model adopts PVC and PPE material to make, and greatly saves metallic material.
Between described PVC internal layer and PPE middle level, be provided with braiding reinforced layer.
Described braiding reinforced layer reticulates setting, and all directions are all stressed, and pressure-bearing is high, improves the anti-bursting property of body.
As preferably, described joint is the copper sleeve of stainless joint or copper sleeve or chromium plating.Non-corrosive, prevents polluted water.
As improvement, described clamping sleeve internal surface be equipped with radial protrusion for penetrating the thorn tip in PPE middle level through stainless steel silk ribbon skin.Can effectively avoid clamping sleeve landing, improve riveting effect, connect more firm.
Accompanying drawing explanation

Fig. 2 is the utility model body sectional view.
In figure:
1, PVC internal layer;
2, PPE middle level;
3, stainless steel silk ribbon is outer;
4, joint;
5, bolt-joint cap;
6, clamping sleeve;
6.1, thorn tip;
Embodiment
Shown in Fig. 1, Fig. 2, a kind of natural gas tube of the utility model, comprises body, and body comprises PVC internal layer 1, PPE middle level 2 and stainless steel silk ribbon skin 3 from inside to outside; Body two ends are equipped with modular connection, and joint 4 places are provided with sealing gasket; Modular connection comprises joint 4 and bolt-joint cap 5, and on the stainless steel silk ribbon skin 3 at joint 4 places, riveting has clamping sleeve 6.
Between described PVC internal layer 1 and PPE middle level 2, be provided with braiding reinforced layer.All directions are all stressed, and pressure-bearing is high, and described braiding reinforced layer is that polyamide fibre or terylene are made.This Tensile strength is large, improves tube body performance.
Described braiding reinforced layer reticulates setting, and all directions are all stressed, and pressure-bearing is high, improves the anti-bursting property of body.
Described joint 4 is the copper sleeve of stainless joint or copper sleeve or chromium plating.
Described clamping sleeve 6 internal surfaces be equipped with radial protrusion for penetrating the thorn tip 6.1 in PPE middle level 2 through stainless steel silk ribbon skin 3.Thorn tip 6.1 when riveting, penetrate in PPE middle level 2, can effectively avoid the landing of clamping sleeve axial direction, connect more firm, longer service life.
Eventually the above, a kind of natural gas tube of the utility model, adopt high-quality PVC material as internal layer and high-quality PPE material as middle level, acid-resistance, corrosion protection, anti-oxidant, aging-resistant, life-span length, good airproof performance, the advantage such as safer; The outer stainless steel silk ribbon parcel that adopts, protection body is avoided wearing and tearing when through body of wall, prevents that body from being staved, and while also preventing body because of tensile buckling attenuation, damages; The increase of clamping sleeve, has strengthened the join strength of modular connection and body, guarantees both difficult drop-offs, and the setting of joint sealing gasket guarantees sealability.The utility model adopts PVC and PPE material to make, and greatly saves metallic material.
