Further, the surface of the rubber protective layer is equipped with non-slip texture.
Further, several described hush pipes are made of acoustical cotton.
Further, the side of the flange is opened up there are six equally distributed mounting hole.
Compared with prior art, the utility model has the advantages that：This kind of corrosion resistant type spiral steel pipe structure, is answered
Steel pipe is protected with sacrificial anode protection, forms a battery structure, zinc coat is anode, and steel pipe is cathode machine, when steel pipe is by corruption
Erosion, zinc coat first starts by oxidation corrosion, and after zinc coat has been corroded, steel pipe just starts to be corroded, and is effectively protected steel pipe,
The corrosion resistance of steel pipe is improved, insulating layer is prevented since pipe band internal-external temperature difference is larger, the steel pipe under the effect of expanding with heat and contract with cold
Damage, several hush pipes are made of acoustical cotton, and acoustical cotton carries out noise reduction to draining sound, reduce noise.
