Abstract
A hot melt reinforced antiseptic steel-plastic adapter relates to an antiseptic steel-plastic adapter for fuel gas pipe bury, which consists of an adapter body, steel adapters of two ends and a polythene pipe adapter. The outside of the steel adapter has a dope layer of static adsorbing double antiseptic modification epoxy powder. The adapter body has the dope layer of static adsorb double antiseptic modification epoxy powder, a hot melt sub and an insulation antiseptic hot contract pipe. The adapter body of the utility model has the dope layer of epoxy powder and is dried to strength the antiseptic capability, furthermore, the utility model is added with an insulation antiseptic hot contract pipe of double layer with a hot melt rubber, thereby having the action of attack voltage resistance no lower than 15KV/mm. The utility model solves well the antiseptic problem of the using process of steel-plastic adapter and has strong capability of electrochemical rusty resisting and high voltage strike resisting.
Description
Technical field the utility model relates to a kind of gas pipeline and moulds crossover sub with the corrosion-resistant steel with burying.
The existing steel of background technique is moulded crossover sub, constitutes at fittings body 2, the steel joint 6 that reaches two ends, polyethylene pipe joint 1.The heavy anticorrosion modified epoxy resin power paint layer 5 of Electrostatic Absorption is arranged outside fittings body, steel joint, and its shock resistance voltage capability is not enough, and it is poor that electrochemically resistant is learned corrosion ability.
Now existing steel-plastic joint application patent, as " protective case formula steel plastic joint " (94229955), it includes steel pipe, containment vessel and plastics pipeline section and is enclosed within spinning end cap on the plastics pipeline section.Its major character is: the welding of steel pipe and containment vessel has the plastics straight joint that is connected with the heat seal of plastics tube section ends and is compressed by the spinning end cap in containment vessel.It compared with prior art has in conjunction with advantages such as simple, good sealing effects, and the plastics straight joint is a standard piece and can reduce manufacturing cost.
The summary of the invention the purpose of this utility model aims to provide that a kind of shock-resistant voltage is not less than 15KV/mm, the hot melt that has extremely strong electrochemically resistant to learn corrosion ability is strengthened anticorrosion steel and moulded crossover sub.
The implementation of the utility model purpose is, hot melt is strengthened anticorrosion steel and moulded crossover sub, by fittings body 2, and steel joint 6, the polyethylene pipe joint 1 at two ends constitute.The steel joint has the heavy anticorrosion modified epoxy resin power paint layer 5 of Electrostatic Absorption outward, and fittings body has the heavy anticorrosion modified epoxy resin power paint layer 5 of Electrostatic Absorption, heat-fusing glue layer 4 and insulating corrosion heat-shrinkable tube 3 outward successively.
Fittings body of the present utility model removes outward the heavy anticorrosion modified epoxy resin power paint layer of Electrostatic Absorption, and through baking, make its antiseptic power stronger, outside it, increased the double-deck insulating corrosion heat-shrinkable tube that heat-fusing glue layer is arranged again, play the effect that shock-resistant voltage is not less than 15KV/mm.The utility model has solved steel well and has moulded the anticorrosion difficult problem of crossover sub in burying the ground using process, has extremely strong electrochemically resistant to learn corrosion and anti-high voltage impact capacity.
