Abstract
The utility model relates to the technical field of pipes, in particular to a corrosion-resistant pipe. The corrosion-resistant pipe comprises a steel pipe body and corrosion-resistant pipes. The corrosion-resistant pipes are fixed to the outer sides and the inner sides of the two ends of the steel pipe body respectively, and corrosion-resistant layers are arranged on the inner sides and the outer sides of the portion, between the corrosion-resistant pipes at the two ends of the steel pipe body, of the steel pipe body. The corrosion-resistant pipe is reasonable in structure and convenient to use; because the corrosion-resistant pipes with large thickness are fixed to the outer sides and the inner sides of the two ends of the steel pipe body respectively, the corrosion-resistant layers can be effectively prevented from being damaged in the welding process, and thus the service life of the steel pipe is prolonged.
Description
Technical field
The utility model relates to pipe fitting technical field, is a kind of corrosion-resistant pipe fitting.
Background technique
Outer wall of steel pipe and inwall when adopting corrosion-inhibiting coating anticorrosion, owing between steel pipe being welding, temperatures involved when corrosion-inhibiting coating can be subject to welding heat and destroying, thereby lose antiseptic property.
Summary of the invention
The utility model provides a kind of corrosion-resistant pipe fitting, has overcome the deficiency of above-mentioned prior art, temperatures involved when it can effectively solve corrosion-inhibiting coating and can be subject to welding heat and destroying, thus lose the problem of antiseptic property.
The technical solution of the utility model is achieved like this: a kind of corrosion-resistant pipe fitting, comprise steel pipe body and corrosion-resistant pipe, outside and inner side at steel pipe body two ends are fixed with respectively corrosion-resistant pipe, and inner side and the outside of the steel pipe body between the corrosion-resistant pipe at steel pipe body two ends are provided with anti-corrosion layer.
There is respectively concave station outside and the inner side at above-mentioned steel pipe body two ends, in concave station, be fixed with corrosion-resistant pipe, the outer side surface of corrosion-resistant pipe that is positioned at steel pipe body two ends outsides is mutually concordant with steel pipe body outer side surface, and the inner side surface that is positioned at the corrosion-resistant pipe inside steel pipe body two ends is mutually concordant with steel pipe body inner side surface.
The above-mentioned outer end that is positioned at the corrosion-resistant pipe of inner side, steel pipe body two ends is respectively taper type wide outside and narrow inside.
The above-mentioned outer end of corrosion-resistant pipe in inner side, steel pipe body two ends and the angle of horizontal plane are between ten degree to ten five degree.
The length of above-mentioned corrosion-resistant pipe is between 12 centimetres to 18 centimetres.
The thickness sum of above-mentioned steel pipe body outside and inner side corrosion-resistant pipe steel pipe body thickness 1/2nd to 3/4ths between.
The utility model is rational in infrastructure, easy to use, by the outside at steel pipe body two ends and inner side, is fixed with respectively the corrosion-resistant pipe that thickness is very large, can effectively prevent from destroying anticorrosive coat when welding, thereby improve the working life of steel pipe.
Accompanying drawing explanation
