With wrap up in second anticorrosion of described arm in order to cover, described second anticorrosion comprise adapt with described arm and an end have the thermal contraction casing tube of horn mouth reduced diameter portion, the flat through hole edge that turns over and be sealedly attached to described attaching sheet, the edge of the horn mouth reduced diameter portion of described thermal contraction casing tube;
The internal surface of described attaching sheet and thermal contraction casing tube is provided with heat-fusing glue layer.
Above-mentioned internal surface refers under anticorrosion cover working state, attaches sheet and heat-shrinkable tube towards the one side of pipe fitting.
As a kind of improvement, the edge of the horn mouth reduced diameter portion of described thermal contraction casing tube is flat to turn over, and utilizes high strength high softening-point adhesive glue to be sealedly attached to the through hole edge of described attaching sheet.
As a kind of improvement, the edge of the horn mouth reduced diameter portion of described thermal contraction casing tube is flat to turn over, and is directly welded in the through hole edge of described attaching sheet.
As a kind of further improvement, the edge of the horn mouth reduced diameter portion of described thermal contraction casing tube is provided with ring-like fixed plate with the place of being tightly connected, through hole edge that attaches sheet.
As a kind of improvement, described thermal contraction casing tube comprises the irradiated crosslinked polyalkene base material.
As a kind of further improvement, described irradiated crosslinked polyalkene base material comprises the radiant crosslinked polyethylene base material.
The utility model using method is as follows:
At first with hot melt rubber stick the part that former whole anticorrosive coat is cut out destruction when the branch pipe welded directly to the run pipe around the arm of whole anti-corrosion pipeline is filled and led up; Then arm is passed the through hole that attaches sheet, thermal contraction casing tube is set in the outside of arm; Attach sheet with the heating of heating tools such as grilled gun then, make the whole anticorrosive coat that attaches sheet and pipeline bonding,, begin circumferentially evenly heating from arm and person in charge joint simultaneously, until finishing whole thermal contraction casing tube heat shrink, the heat-fusing glue layer that attaches plate inner surface melts, closely bond thermal contraction casing tube heat shrink, the heat-fusing glue layer hot melt that internal surface attaches with the whole anticorrosive coat on the original anti-corrosion pipeline, also closely be attached to the outer surface of arm, thereby finish anticorrosive work.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
1, anticorrosion leak source can not occur, guarantee service life and the safety of anticorrosive quality and pipeline.Because thermal contraction casing tube seals sticking (weldering) in advance and connects the through hole edge that is fixed in the attaching sheet, so sealing is very good, can guarantee the no leak source in special-shaped zone at turning; Generally speaking, whole anticorrosion cover adopts overall structure, makes the leak source probability reduce greatly, has improved the corrosion-resistant effect.
2, easy to use.The utility model is set in described arm outside with thermal contraction casing tube in use, heats again, makes hot melt adhesive thawing and contraction be attached to a tube-surface and gets final product, and constructing operation is very simple;
3, attractive in appearance.Changed and utilized the mode of hindering the band multi-lay winding of mending in the traditional approach, adopted overall structure to wrap up anticorrosion, more attractive in appearance;
4 economical with materials operating expenses.The anticorrosion cover that the utility model provides can significantly reduce the use of material, is possessing under the prerequisite of identical antiseptic effect, has saved wide variety of materials and operating expenses, has reduced cost.
In a word, the utility model can carry out effective environmental sealing with the special-shaped zone between anti-corrosion pipeline and the branch pipe welded directly to the run pipe, thoroughly reduce difficulty of construction, guarantee anticorrosive quality, very easily meet or exceed whole pipeline corrosion protection designing requirement, the problem of the whole pipeline service life of influence is solved at all, can reduce the construction management difficulty simultaneously, reduce labor intensity of operating personnel.
