Abstract
The utility model belongs to the pipeline technology field, which discloses a plastic sprayed pipe specially used in coal mines. The technical proposal adopted is that the utility model comprises a liner pipe with certain rigidity, and plastic layers with anti-corrosive performance are coated on the inner and outer walls of the liner pipe. Because the liner pipe of the plastic sprayed pipe specially used in coal mines has certain rigidity, and plastic layers with anti-corrosive performance are coated on the inner and outer walls of the liner pipe, the collapsing phenomenon can't occur during the using process, guaranteeing expedite pipeline, and having longer service life.
Description
Technical field
The utility model belongs to the pipe technology field, relates in particular to a kind of have certain rigidity and withstand voltage properties, the special-purpose plastic-blasting pipe in colliery wear-resisting and that anti-static electricity property is good.
Background technique
At present, water delivery of using in the colliery and gas pipeline must have good antistatic and anti-flame retardant property, therefore many various plastics of employing or rubber material are prepared from, but the pipeline that these are prepared from by plastics or rubber material is because rigidity and withstand voltage properties are relatively poor, in use often be crushed or explosion, influenced the gentle conveying of water.
The model utility content
The purpose of this utility model just provides a kind of have certain rigidity and the good special-purpose plastic-blasting pipe in colliery of withstand voltage properties.
For achieving the above object, the technological scheme that the utility model adopted is:
The special-purpose plastic-blasting pipe in a kind of colliery comprises the bushing pipe with certain rigidity, is coated with the plastic layer with decay resistance on the internal face of this bushing pipe and outer wall.
The special-purpose plastic-blasting pipe in colliery provided by the utility model, compared with prior art have the following advantages: one has certain rigid owing to constitute the bushing pipe of the special-purpose plastic-blasting pipe in this colliery, therefore, in use can not flatten phenomenon, guarantee the unimpeded of pipeline; Its two owing on the inside and outside wall of the special-purpose plastic-blasting pipe in this colliery, be coated with plastic layer with decay resistance, therefore working life of having improved pipeline.
Description of drawings
Accompanying drawing is the structural representation of the special-purpose plastic-blasting pipe in colliery provided by the utility model.
Embodiment
As shown be the structural drawing of the special-purpose plastic-blasting pipe in colliery, promptly the structure of the special-purpose plastic-blasting pipe in this colliery includes the bushing pipe 1 that the metallic steel pipe is made, and is coated with the plastic layer 2,3 with corrosion-resistant, antistatic and anti-flame retardant property on the inside and outside wall of this bushing pipe.
Claims (1)
1, the special-purpose plastic-blasting pipe in a kind of colliery is characterized in that: comprise the bushing pipe with certain rigidity, be coated with the plastic layer with decay resistance on the internal face of this bushing pipe and outer wall.
