Abstract
A pipe fitting relates to pipe elements and comprises an outer casing (3) and a lining (5), and is characterized in that a filling layer (4) is disposed inside a gap between the outer casing (3) and the lining (5). The pipe fitting has the advantages that the gap between the lining layer and a base layer is eliminated by filling fillers in the gap between the lining and the outer casing to form the filling layer, and accordingly use pressure of an elbow is increased. The pipe fitting is particularly applicable to industries of high-medium pressure corrosive media.
Description
Technical field
The utility model relates to piping element.
Background technique
Korrosionsmedium industries such as chemical industry, particularly the salt chemical engineering industry prevents the corrosion of medium to steel to pipeline, threeway, elbow liner with the way of anti-corrosion material usually, but because of metallic material and lining material expansion system difference very big, after lining pipeline, threeway, elbow-making are finished, will produce the gap between backing layer and pipeline, threeway, the elbow, thereby limit the working pressure of lining pipeline, threeway, elbow.Therefore, present lining pipeline, threeway, elbow can only be used for low pressure pipeline, and after working pressure increased, backing layer was easy to break, and causes pipe fittings such as metallic conduit, threeway, elbow very fast by heavy corrosion.
The model utility content
Technical problem to be solved in the utility model is, can avoid the lining effective erosion-resisting pipe fitting that breaks thereby provide a kind of.
The technological scheme that the utility model solve the technical problem employing is that a kind of pipe fitting comprises shell and lining, it is characterized in that, is provided with packed layer in the gap between shell and lining.
Further, shell is provided with fill orifice and exhaust port.Described packed layer solidifiable material is as epoxy resin etc.Described pipe fitting is pipeline, elbow or threeway.
The beneficial effects of the utility model are to form packing layer by the gap of filling filler between lining and shell, the gap between elimination backing layer and the basic unit, thereby the working pressure of raising elbow.The utility model is specially adapted to the industry of mesohigh Korrosionsmedium.
" solidifiable material " as herein described is meant under the normal temperature that particularly high hardness is solid-state for solid-state, be the material of liquid state under some process conditions, for example epoxy resin etc.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is embodiment's 1 an of the present utility model schematic representation.
Fig. 2 is embodiment's 2 an of the present utility model schematic representation.
Fig. 3 is embodiment's 3 an of the present utility model schematic representation.
Embodiment
Embodiment 1: referring to Fig. 1.
Present embodiment is a channel bend.Lining 5 and the gap between the shell 3 at elbow form packed layer 4 by fillers such as infusion epoxy resins.Filler is liquid when perfusion, and solidifying the back is the solid-state of high hardness, has eliminated the gap between lining 5 and the shell 3, reaches the purpose that strengthens the lining voltage endurance capability.Shell is provided with through hole, is respectively fill orifice 6 and exhaust port 2.
The working process of present embodiment is: after flange 1 and elbow assembly welding finished, the diverse location before the processing lining on shell was offered through hole, in order to perfusion filler and exhaust.After the lining completion of processing, filler pushes perfusion from the bottom up, and the hole on top is used for exhaust and checks whether perfusion is full.
Claims (6)
1. a pipe fitting comprises shell (3) and lining (5), it is characterized in that, is provided with packed layer (4) in the gap between shell (3) and lining (5).
2. pipe fitting as claimed in claim 1 is characterized in that, shell (3) is provided with fill orifice (6) and exhaust port (2).
3. pipe fitting as claimed in claim 1 is characterized in that, described packed layer (4) is the solidifiable material.
4. pipe fitting as claimed in claim 1 is characterized in that, described pipe fitting is pipeline, elbow or threeway.
