Abstract
The utility model relates to a structure improvement to an explosion welding composite tube plate of the existing tube array type heat exchanger. A thin titanium composite layer is combined on the surface of a base layer of a tube plate made of carbon steel or stainless steel in the mode of explosion, and a layer of corrosion-resistant sealing ring is arranged on the surface of the thin titanium composite layer correspondingly to the sealing surface of the tube plate, and the thin titanium composite layer, the corrosion-resistant sealing ring and the sealing surface of the tube plate form a whole. The annular surface of the corrosion-resistant sealing ring is processed to be the sealing surface of the tube plate. The corrosion-resistant sealing ring is made of TA 9 materials. The corrosion-resistant sealing ring is a sealing ring with a concave surface or a sealing ring with a concave surface or a plane. The utility model can improve the capacity of the titanium composite tube plate to resist crevice corrosion, and enables the composite tube plate to perform multiple functions.
Description
The novel architecture advances that relates to a kind of to existing tubular heat exchanger explosive welding clad tubesheet of this reality.
The explosive welding clad tubesheet utilizes explosive as the energy, and with two kinds of metal materials that can not carry out molten solder with conventional method, for example the titanium material is a basic unit for answering layer and ordinary carbon steel or stainless steel, and combining together by the explosive welding mode reaches metallurgical binding.The decay resistance of nonferrous materials such as the multiple layer of utilization and ordinary carbon steel or stainless steel are the load-carrying properties of basic unit, realize reasonable use nonferrous metal resource, reduce the heat exchanger manufacturing cost, satisfy the requirement of Chemical Manufacture for the tubular heat exchanger decay resistance.
Usually the multiple layer sealing surface 3 of the tube sheet of tubular heat exchanger often is processed into the structure as Fig. 1, and the multiple layer of needed titanium 2 material thickness are bigger in ordinary carbon steel or the stainless steel basic unit 1, cause coloured genus waste of material, have influence on the economy of equipment.Owing in the equipment use, on multiple layer sealing surface 3, have minim gap, form the medium delay and make the multiple layer 2 titanium material of clad tubesheet produce crevice corrosion and reduce its service life simultaneously, can not give full play to the due effect of clad tubesheet.
The purpose of this utility model promptly is that the multilayer structure in the existing clad tubesheet is done further improvement, and a kind of modified titanium-steel explosive welding clad tubesheet that improves opposing titanium material clad tubesheet to the slit corrosive power is provided.
Technical solution of the present utility model:
A kind of modified titanium-steel explosive welding clad tubesheet, it includes carbon steel or Stainless Steel Tubular Plates basic unit, it is characterized in that being compounded with the multiple layer of thin layers of titanium at the surface explosion of tube sheet basic unit, the position of corresponding tube sheet sealing surface is provided with one deck corrosion resistant sealing ring on the surface of the multiple layer of thin layers of titanium, they are an integral body, and the annular surface of corrosion resistant sealing ring is the tube sheet sealing surface through processing.Above-mentioned corrosion resistant sealing ring adopts the TA9 material, it or be a concave surface sealing ring, or be convex surface or flat seal ring.
The utility model alloy material sealing ring of assembly welding again on the multiple layer titanium material of blast clad tubesheet, the sealing ring surface promptly forms sealing surface through processing.Because the utility model is added with the alloy material sealing ring, then the thickness of the multiple layer of titanium material can reduce greatly, so saved titanium material or nonferrous materials greatly, economic benefit improves.Because sealing ring of the present utility model adopts erosion-resisting alloy material, as TA9 material etc., so overcome on the multiple layer sealing surface of existing tube sheet and had minim gap, forming medium is detained the multiple layer titanium material generation crevice corrosion that makes clad tubesheet and reduces the defective in its service life, improve the ability of titanium material clad tubesheet opposing crevice corrosion, given full play to the due effect of clad tubesheet.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the partial structurtes schematic diagram of existing clad tubesheet.
Fig. 2 is the partial structurtes schematic diagram of the utility model clad tubesheet.
As Fig. 2, the utility model includes carbon steel or Stainless Steel Tubular Plates basic unit 1, characteristics of the present utility model are, surface explosion in tube sheet basic unit 1 is compounded with the multiple layer 4 of thin layers of titanium, the position of corresponding tube sheet sealing surface is provided with one deck corrosion resistant sealing ring 5 on the surface of the multiple layer 4 of thin layers of titanium, they are an integral body, and the annular surface of corrosion resistant sealing ring 5 is tube sheet sealing surface 6 through processing.Corrosion resistant sealing ring 5 of the present utility model can adopt the TA9 material, and it can be a concave surface sealing ring, also can be convex surface or flat seal ring.Shown in Fig. 2 is concave surface sealing ring 5, and the step underrun of sealing ring 5 is welded to connect in the shallow slot 7 that the corresponding circle cars in the multiple layer of thin layers of titanium 4 surface make, its concave surface through processing tube sheet sealing surface 6.It can reach and effectively overcome crevice corrosion like this, saves nonferrous materials, gives full play to metal material excellent properties separately.
