Description
Technical field
The utility model belongs to pipe fitting manufacturing technology field, particularly a kind of heavy wall bimetallic three-way pipe cold moudling device.
Background technology
The pipe joint of three openings be called three-way pipe (
pipe tee (T), three-way tube, three-way pipe).Three-way pipe is widely used in the pipe network of carrying liquid, gas.Different because of pumped (conveying) medium, the material of three-way pipe is divided into: cast iron, cast steel, cast copper, cast aluminium, plastics, glass etc.
Three-way pipe has an import, two outlets; Or two imports, an outlet.The global shape of three-way pipe has T shape and Y shape, has the isometrical mouth of pipe, also has the reducing mouth of pipe, for three identical or different pipeline junctions.Its main effect is to change flow direction.Can be used for hydraulic pipeline, pipeline road and various fluid chemical material transfer pipeline.Be mainly used in the engineering fields such as water conservancy (water-saving irrigation, water supply and drainage), the energy (oil, natural gas, nuclear industry), building.
In the last few years; development along with market; the laying of oil transportation in all parts of the country, gas pipeline is more and more; the market demand of pipe fitting product increases day by day; often can use three-way pipe to connect other pipe fitting in order to increase shunting; existing three-way pipe is mostly single material, or with pipe line steel, carbon steel, or use stainless steel.Carbon steel three-way pipe pressure-bearing is strong, and low price is not but corrosion-resistant, and stainless steel three-way pipe is corrosion-resistant but bearing capacity is poor, expensive.Yet along with petroleum gas, chemical industry, developing rapidly of boats and ships exploitation, corrosive pipeline environment has proposed higher to conveyance conduit, more harsh corrosion-resistant requirement, and as the three-way pipe for pipeline shunt, use common carbon steel or stainless steel, its corrosion resistance, bearing capacity, toughness and intensity are all poor, can not meet the requirement for height of pipeline.
Threeway is a kind of pipe fitting for pipe branch place.For adopting seamless pipe to manufacture threeway, common adopted technique has two kinds of hydraulic expanding-forming and hot formings at present.
A. hydraulic expanding-forming
The hydraulic expanding-forming of threeway is by a kind of forming technology of the nose balance expansion arm of metal material.Its process is to adopt special hydraulic press, by filling liquid in the pipe with threeway equal diameters, by two horizontal side cylinder synchronous centering motion extrusion tube blanks of hydraulic press, smaller volume after pipe is squeezed, with pipe smaller volume, pressure raises liquid in pipe, when reaching the needed pressure of tee branch expansion, under the double action of metal material fluid pressure in side cylinder and pipe, along dies cavity, flow and expansion arm.
B. hot forming
Threeway hot forming is to be greater than the pipe of threeway diameter, flattens approximately to the size of threeway diameter, opens a hole at the position of stretching arm; Pipe, through heating, is put into finishing die, and in pipe, is packed the punch die of stretching arm into; Under the effect of pressure, pipe is by radial compression, and in the process of radial compression, metal flows and form arm under the stretching of punch die to arm direction.Whole process is that the drawing process by the radial compression of pipe and arm position is shaped.Different from Hydraulic Bulge Forming of Tee tubes, the metal of hot-pressed three-way pipe fitting arm is that the radial motion by pipe compensates, so also referred to as radial compensation technique.
At present, also occurred bimetallic composite tee pipe on market, three-way pipe body is made by high-strength line-pipe steel, and three-way pipe inner body wall metallurgy or soldering have stainless steel anti-corrosion layer.But for heavy wall bimetallic composite tee pipe, if the mode with hot pressing or above-mentioned hydraulic pressure, the in the situation that of heating, the stainless steel layer of the inside has been easy to fold, internal diameter physical dimension does not guarantee, also be easy to destroy bimetallic stainless steel composition, cause welding, and the three-way pipe heavy wall forming out is inhomogeneous, outward appearance is coarse, physical dimension is undesirable, when pipeline and three-way pipe welding, often there is such-and-such problem, cause weld seam not firm, affect the normal operation of oil transportation, gas pipeline.
