Abstract
Inner surface -welding bimetal pipe cap, including the pipe cap body, the pipe cap body includes a pipe cap bottom plate and a cydariform section of thick bamboo that is the cydariform, the inner wall of a cydariform section of thick bamboo is rot. Arcwall face, the top opening of a cydariform section of thick bamboo, base and the pipe cap bottom plate body coupling of a cydariform section of thick bamboo, its characterized in that: it has the overlay to go up whole build -up welding with the upward side of pipe cap bottom plate on the cydariform section of thick bamboo inner wall, and the overlay comprises the sub - overlay more than two -layer, and the gross thickness of overlay is 2 -4mm, the overlay comprises a plurality of welding beads, the technological problem that has solved effectively that ocean engineering, oil shale air to open are adopted and corroded at the occasion technical field pipeline that uses the acid chloride catalyst.
Description
Technical field
The utility model belongs to Machining Technology field, particularly relates to a kind of pipe cap.
Background technique
At present, along with the fast development of plumbing installations, oil transportation in all parts of the country, gas pipeline are laid the market demand and are day by day increased, particularly ocean engineering, oil shale gas exploitation and in the occasion using acid chloride catalyzer, very high to the anticorrosive wear-resistant of pipe fitting, tensile property, high temperature resistance peeling ability and resisting corrosion of chlorine ion cracking Capability Requirement.The pipe fitting of machinery produced with combination expands with heat and contract with cold when welding, and is unfavorable for welding.
Model utility content
The purpose of this utility model is to provide inner wall overlaying bimetal pipe cap, ensures that pipe cap can not layering when welding.
The technical solution of the utility model is:
Inner wall overlaying bimetal pipe cap, comprise pipe cap body, pipe cap body comprises pipe cap base plate and the cydariform cylinder in cydariform, the inwall of cydariform cylinder is pivotal arc shaped surface, the upper opening of cydariform cylinder, the base of cydariform cylinder is connected with pipe cap base plate one, it is characterized in that: all pile on cydariform cylinder inwall and on the upper side of pipe cap base plate and be welded with overlay cladding, overlay cladding is made up of two-layer above sub-overlay cladding, and the total thickness of overlay cladding is 2-4mm; Overlay cladding is made up of multiple welding bead, and ringwise, the welding bead on cydariform cylinder inwall distributes along the center line of cydariform cylinder the welding bead of the overlay cladding on described cydariform cylinder inwall successively; Ringwise, welding bead sets gradually from inside to outside welding bead on pipe cap base plate centered by the center line of cydariform cylinder; Or the welding bead on pipe cap base plate distributes twist; As the nominal diameter≤DN200 of pipe cap body, the width of welding bead is 4 ~ 8mm; As the nominal diameter >=DN200 of pipe cap body, the width of welding bead is 3 ~ 6mm.
The height of welding bead is 1 ~ 2mm.
The thickness of the sub-overlay cladding of individual layer is 1-2mm.
The material of overlay cladding is stainless steel, nickel-base alloy or abrasion resistance alloy.
Overlay cladding is superposed by two-layer built-up welding and is formed.
The amount of lap of adjacent welding bead is 30% ~ 50%.
The present invention is under the prerequisite not changing pipe fitting performance, at a kind of Ni-Cr solid solution strengthened alloy of finished product inner annular built-up welding stainless steel, nickel-base alloy or abrasion resistance alloy that pushing is good, main intensified element is Mo and Nb, and its feature main manifestations is: 1, from low temperature to high temperature 980 degrees Celsius all there is good stretchability and anti-fatigue performance; 2, there is excellent fatigue strength and resisting corrosion of chlorine ion cracking ability; 3, there is high temperature resistance peeling and oxidability; 4, in seawater and industrial gas environment, produce corrosion hardly, to seawater and salt solution, there is very high corrosion resistance.The utility model belongs to annular built-up welding, meet the high quality of client, high standard demand, and feature is widely used so that its high performance-price ratio, highly corrosion resistant, high wear resistance and high temperature resistance be anti-oxidant etc., achieve significant economic benefit and social benefit, efficiently solve ocean engineering, oil shale gas exploitation and using the technical barrier of occasion technical field corrosive pipeline of acid chloride catalyzer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing A of Fig. 1.
Embodiment
As shown in Figure 1, 2, the utility model comprises pipe cap body 1, and pipe cap body 1 comprises pipe cap base plate 2 and the cydariform cylinder 3 in cydariform, and the inwall of cydariform cylinder 3 is the upper opening of pivotal arc shaped surface, cydariform cylinder 3, and the base of cydariform cylinder 3 is connected with pipe cap base plate 2 one.
Pipe cap base plate 2 and cydariform cylinder 3 include basic unit 4, in the basic unit 4 of pipe cap base plate 2 and cydariform cylinder 3, all heap is welded with overlay cladding 5, overlay cladding 5 material is stainless steel, nickel-base alloy or abrasion resistance alloy, main intensified element is Mo and Nb, overlay cladding 5 is made up of (the present embodiment is 2 layers) two-layer above sub-overlay cladding 6, the thickness of sub-overlay cladding 6 is the total thickness H=2-4mm of 1-2mm, overlay cladding 5.Overlay cladding 5 is made up of multiple welding bead 7, and ringwise, the amount of lap of adjacent welding bead 7 is 30% ~ 50% to welding bead 7.
Some the welding beads 7 of pipe cap base plate 2 distribute successively along the center line of cydariform cylinder 3, the welding bead 7 at pipe cap base plate 2 place is annular or spirality, during for annular, welding bead 7 by cydariform cylinder 3 center line centered by distribute successively from inside to outside, the radius of welding bead 7 expands from inside to outside successively.
As the nominal diameter≤DN200 of pipe cap body 1, the width m=4 ~ 8mm of welding bead 7.
As the nominal diameter >=DN200 of pipe cap body 1, the width m=3 ~ 6mm of welding bead 7.
Height h=1 ~ the 2mm of welding bead 7.
Working process: built-up welding welding gun is split type welding gun, ensures inwall each point built-up welding consistency of thickness.
This product is annular built-up welding, compares vertical shape heap and is welded in pipeline radial force more rationally, and more reasonable for fluid scouring corrosion, and the binding site of longitudinal measure is easily washed and corrodes into comb teeth-shaped, affects working life, and circumferential weld does not then exist this phenomenon.
