Abstract
The utility model discloses a butt welding joint for a titanium lined composite metal tube, which includes composite metal tube bodies (7 and 7'), wherein the composite metal tube bodies (7 and 7') are provided with carbon steel basal body steel tube layers (1 and 1') and titanium lined corrosion-resisting layers (2 and 2'); the titanium lined corrosion-resisting layers (2 and 2') at the butted ends of the composite metal tube bodies (7 and 7') are exposed out of the carbon steel basal body steel tube layers (1 and 1'), and are fixed through welding; and the carbon steel basal body steel tube layers (1 and 1') are fixedly connected through a butt welding head (8). The butt welding joint provided by the utility model solves the problem in the prior art that safety hazards exist in the normal use of the composite metal tube as the titanium lined corrosion-resisting layers of the composite metal tubes are easy to melt through when the titanium lined composite metal tubes are butted through the butt welding joint.
Description
Technical field

Background technique
At present, composite steel tube is soaring year by year in the use amount of all trades and professions.Carry out compoundly according to the corresponding inner liner metal material of the different choice of composite steel tube fed sheet of a media, this is an industry general knowledge.The technical pure titanium or titanium alloy has outstanding decay resistance, is the preferred material of numerous chemical corrosion environment, comprises chloride solution, seawater, the chloro bleaching agent of oxidation.Titanium alloy also has characteristics such as low density (density p=4.51 gram/cubic centimetres), high tenacity.Titanium has very strong corrosion resistance in more medium, especially the corrosion resistance in neutrality and Oxidant is very strong.Along with high speed development of national economy, market is more and more for the demand of titanium or titanium alloy, owing to the reason of the rare and manufacture cost of resource; The price of titanium material is high always; Cost is very high beyond doubt for the user for this point, and the compound success of titanium lined composite metal pipe just can address the above problem; The titanium lined composite metal pipe is in concrete practical applications process; Usually need many titanium lined composite metal pipes are linked together through the butt joint soldering tip, still adopt existing butt joint soldering tip in work progress very easily with titanium lined anti-corrosion layer burn through, the normal use of composite metal pipe is brought certain potential safety hazard.
Summary of the invention
The object of the invention provides a kind of titanium lined composite metal pipe butt welding joint; The utility model has solved the butt joint soldering tip easy titanium lined anti-corrosion layer burn through with composite metal pipe in butt joint titanium lined composite metal pipe process that adopts existing technology, the normal use of composite metal pipe is stayed the problem of potential safety hazard.
The present invention realizes through following technological scheme:
A kind of titanium lined composite metal pipe butt welding joint; Comprise composition metal tube body (7,7 '); Composition metal tube body (7,7 ') is provided with plain steel steel pipe layer (1,1 '), titanium lined anti-corrosion layer (2,2 '); It is characterized in that: said composition metal tube body (7,7 ') butt end titanium lined anti-corrosion layer (2,2 ') exposure is in plain steel steel pipe layer (1,1 '); Fixing between the titanium lined anti-corrosion layer (2,2 ') through welding, be fixedly connected through butt welding joint (8) between the plain steel steel pipe layer (1,1 ').。
The further technological scheme of the present invention is:
Said butt welding joint (8) is made up of two semicircle pressure-bearing clips (3,3 '); Fixing between two semicircle pressure-bearing clips (3,3 ') through welding; Shoulder position, pressure-bearing clip (3,3 ') both sides forms groove (31,31 '), and root face (32,32 ') is formed at pressure-bearing clip (3,3 ') groove (31,31 ') bottom.
The present invention's technological scheme further is:
The thickness of said pressure-bearing clip (3,3 ') is identical with the thickness of plain steel steel pipe layer (1,1 '), and the material of pressure-bearing clip (3,3 ') is identical with the material of plain steel steel pipe layer (1,1 ').
The present invention's technological scheme further is:
Groove (31, the 31 ') angular range of said pressure-bearing clip (3,3 ') is 40 degree～60 degree, and root face (32,32 ') is 0.8mm～1.2mm.
The present invention's technological scheme further is:
Be filled with scolder (4) in the groove (31,31 ') of said pressure-bearing clip (3,3 ') and the gap between the plain steel steel pipe layer (1,1 '), the gap between root face (32,32 ') and the plain steel steel pipe layer (1,1 ') forms space (6).
The present invention's technological scheme further is:
Said composition metal tube body (7,7 ') butt end titanium lined anti-corrosion layer (2,2 ') exposure is in plain steel steel pipe layer (1,1 ') 25mm～35mm.
The present invention compared with prior art has obvious advantage,
One, the butt end titanium lined anti-corrosion layer exposure of the composite metal pipe of the utility model can realize the independent butt joint of titanium lined anti-corrosion layer in plain steel steel pipe layer, has guaranteed the sealing of composite metal pipe internal flow.
Two, the butt welding joint of the utility model is made up of two semicircle pressure-bearing clips; Be filled with scolder in the gap between the groove of pressure-bearing clip and the plain steel steel pipe layer; Gap between root face and the plain steel steel pipe layer forms the space; Not only can guarantee the welding stability of pressure-bearing clip and plain steel steel pipe layer, and the space between root face and the plain steel steel pipe layer, can guarantee effectively that molten metal material and scolder can not touch the lower titanium lined anti-corrosion layer of fusing point in the welding process; Thereby avoid the burn through titanium lined layer by layer corrosion-resistant, for the stable operation of composite metal pipe has been eliminated potential safety hazard.
