Technical field
It the utility model is related to a kind of pipeline, more particularly to a kind of mine gas extraction pipeline.
Background technology
At present, coal bed methane extraction pipe has following several pipelines at present：Polyethylene pipe, polyvinyl chloride pipe, ordinary steel
Pipe, leaching modeling plastic-coated steel.Though polyethylene, polyvinyl chloride are corrosion-resistant but its anti-flammability and antistatic behaviour are extremely difficult to require, i.e.,
Make to reach requirement also because its additive excessively influences pipe workpiece quality；Ordinary steel is then because heavier-weight, installation production have larger
Inconvenience；Thin-wall steel tube is rolled using steel band, and weight declines, and cost is low, and beneficial to transport and installation, but ring stiffness is low, is easily occurred
Negative pressure suction is flat, influences the efficiency to draw out methane.Normal practice is that waveform is rolled on thin-wall steel tube, improves pipe ring stiffness, full
Sufficient requirement, but in use, waveform has resistance, produces noise.Therefore, the deficiency for more than, it is desirable to provide a kind of
Tensile strength is big, good toughness, resistant to many organic solvent act on, heat-resisting quantity is good, and the good mine gas of anti-electrostatic fire retardant performance is taken out
Put pipeline.
