Abstract
The utility model provides a stainless-steel pup joint in enamel anti-corrosive pipelines, which comprises a carbon steel pipe, wherein the middle part of the carbon steel pipe is provided with a stainless-steel welding seam, the stainless-steel welding seam is arranged on a stainless-steel joint, both ends of the stainless-steel welding seam are provided with dissimilar steel welding seams, and the outer layers of the dissimilar steel welding seams are provided with anti-corrosive coatings; and the utility model has the advantage of solving the problem of connection of enamel-sprayed pipelines with small caliber.
Description
Technical field
The utility model relates to a kind of stainless steel short circuit, is specifically related to the ducted stainless steel short circuit of a kind of enamel anticorrosion.
Background technique
Though the pipe welding port guard technology has solved the difficult problem that the sprayed ceramic pipeline connects at present, but the mountain is in the restriction that is subjected to the surfacing torch, when pipe diameter during less than 89mm, the surfacing torch can not well extend in the pipeline, make surfacing work be affected, can not get a desired effect, adopt the stainless joint technology for more small-bore sprayed ceramic pipeline for this reason, promptly earlier at two of pipeline welding two stainless steel rings (length is 80-100mm), carry out the preparation section of coating then, stainless steel ring is welded together during welding with stainless steel electrode.
Summary of the invention
For solving the deficiencies in the prior art, the utility model provides a kind of enamel anticorrosion ducted stainless steel short circuit.
Technical solution adopted in the utility model is: the ducted stainless steel short circuit of a kind of enamel anticorrosion, form by carbon steel tube, middle part at carbon steel tube is provided with stainless steel weld joint, stainless steel weld joint is on stainless joint, the two ends of stainless steel weld joint are provided with dissimilar metal weld, and the skin of dissimilar metal weld is provided with corrosion-inhibiting coating.
The beneficial effects of the utility model are: solved the difficult problem that the sprayed ceramic small-bore pipeline connects.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Wherein: 1 dissimilar metal weld, 2 stainless steel weld joints, 3 corrosion-inhibiting coatings, 4 carbon steel tubes, 5 stainless joints.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, the ducted stainless steel short circuit of a kind of enamel anticorrosion is made up of carbon steel tube 4, be provided with stainless steel weld joint 2 at the middle part of carbon steel tube 4, stainless steel weld joint 2 is on stainless joint 5, and the two ends of stainless steel weld joint 2 are provided with dissimilar metal weld 1, and the skin of dissimilar metal weld 1 is provided with corrosion-inhibiting coating 3.
