the utility model provides a compound pipe for natural gas collection is defeated, includes the body, the body comprises inner tube, outer tube and enhancement steel pipe, the intraductal suit inner tube of outer tube, and the outer tube periphery suit strengthens the steel pipe and strengthens steel pipe surface cold plating corrosion-resistant zinc layer, the outer tube surface is equipped with the silicate heat preservation, and strengthens and be equipped with the waterproof layer between steel pipe and the silicate heat preservation, the inner tube internal surface is equipped with the ageing resistance layer, the body surface is equipped with fixed lug.
Furthermore, an internal thread is arranged on the inner surface of one end of the pipe body, and an external thread corresponding to the internal thread is arranged on the outer surface of the other end of the pipe body.
Further, the inner pipe is made of polyethylene material, and the outer pipe is made of ethylene-vinyl alcohol copolymer.
Further, the anti-aging layer is made of polyurethane materials.
Further, the waterproof layer is made of PVC materials.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. through setting up the enhancement steel pipe, strengthen the intensity that the steel pipe can improve this composite pipe, make it when burying underground, reduce because of peripheral soil changes and lead to this composite pipe to take place the possibility of deformation, improve this composite pipe's stability.
2. Through setting up fixed lug, the fixed block can increase this compound pipe when fixed with the frictional force of fixed position, for operating personnel reduces the fixed degree of difficulty, increases work efficiency.
3. Through setting up anti-aging layer, anti-aging layer prolongs the life of this compound pipe for it can not be because of the overlength during the use, and lead to sealed effect variation, and then influences the gas transmission effect.
4. Through setting up the silicate heat preservation, the silicate heat preservation can reduce this compound pipe and external cold and hot exchange, when the external temperature is lower, can prevent that the natural gas line internal ponding from freezing, blocks up the pipeline.
