Description
Technical field
A kind of gas steel pipeline anticorrosive heat-shrinkable double-wall pipe is the utility model is related to, belongs to gas pipeline corrosion-resistant field.
Background technology
City gas pipeline buried pipeline joint, at interface weld seam repaired mouth, building gas pipe, service pipe, indoor pipe is through walls, at through-flooring
And the indoor anti-corrosion for secretly setting gas pipeline etc. is difficult construction, antiseptic effect is also undesirable, leakage of often being perforated caused by corrosion
Gas, natural resources is caused to waste, combustion gas quality declines and gas leakage security incident.As can be seen here, city gas pipeline is prevented
The importance of rotten problem.
The content of the invention
The combustion gas that the utility model passes through outer wall crosslinking with radiation macromolecule pyrocondensation tube layer and inner wall anti-corrosive seal hot melting glue-line
Steel pipe corrosion-proof pyrocondensation double-wall pipe, solves above mentioned problem.
The utility model provides a kind of gas steel pipeline anticorrosive heat-shrinkable double-wall pipe, the gas steel pipeline anticorrosive heat-shrinkable double-wall pipe
Including outer wall crosslinking with radiation macromolecule pyrocondensation tube layer, inner wall anti-corrosive seal hot melting glue-line；
The gas steel pipeline anticorrosive heat-shrinkable double-wall pipe is enclosed on the buried pipeline joint of gas pipeline, interface weld seam repaired mouth
Place, at building gas pipe, service pipe, indoor pipe through-flooring through walls and interior at least one of are secretly set at gas pipeline.
Outer wall crosslinking with radiation macromolecule pyrocondensation tube layer described in the utility model has insulation, cracking resistance, strong convergent force, resistance to
The performances such as mill, creep resistant, heat-resisting/oxygen aging, impact resistance, ultraviolet resistance.
Inner wall anti-corrosive seal hot melting glue-line described in the utility model has that peel strength is high, adhesion strength is strong, resistance toization to steel pipe
Learn the performances such as burn into soaking-resistant, the infiltration of resistance to steam, good airproof performance.
Inner wall anti-corrosive seal hot melting glue-line described in the utility model is preferably many ribs structure.
The pipe bent position of gas pipeline described in the utility model is preferably to be cased with least one gas steel pipeline anticorrosive heat-shrinkable double-walled
Pipe.
The utility model has the beneficial effect that：
Gas steel pipeline anticorrosive heat-shrinkable double-wall pipe described in the utility model is easy to operate, wall thickness, longitudinal uniform, both ends after pyrocondensation
Glue overflows uniform, no cracking alice phenomenon, safe to use.
