Product name:Titanium Elliptical Dished Head
Standard: ASME VIII-I, DIN28013
Material: Titanium GR1, GR2
Size: Customized
Titanium Hemispherical Dish Head
Brand name LHTi
Product name Titanium Hemispherical Dish Head
Material Titanium & titanium alloy (Grade 1 Grade 2 Grade 7 Grade 12 etc.)
Size DN - 100mm : 6000mm (customized size avaliable)
Wall Thickness 3mm ~ 300mm (customized thickness available)
Process Type Hot pressing, cold pressing, cold spinning
Connection Type Butt-welded or threaded
Edge Type Bevel, Plain or as required
Process of depression
Once the plate is cut into a circle (using a circular cutter, laser, plasma or other methods), the resulting plate is formed under the press and will be crowned with the plate by multiple impacts on the whole surface.
In order to make different types and diameters of disc ends, a disc press must be equipped with a set of molds with different radii. The serving process is quite slow. Depending on the size and material of the plate, it usually takes several hours. This process can be automated by using a CNC manipulator. It is possible to find a press with CNC, which can handle more than 10 shafts and can run automatically for several hours.
In addition to automation, another important factor in the disk making process is speed. The two speed press can greatly increase the output.
The punch presses the workpiece continuously. This means that the structure of disc press is easily affected by material fatigue; Therefore, the life of the press designed to save cost may be very short, showing the first crack of the structure in a very short time. The press designed with HPT has better fatigue resistance. This design consists of four main parts: upper beam, lower beam and two columns. The two beams are connected with the column through the hydraulic preload pull rod. Compared with seam welding or bolts, these tie rods can better resist continuous stress, so as to provide more elasticity to the structure.
Dished multi center end
A special dished end is widely used in truck can body manufacturers: multi center dished end. These disc-shaped ends are usually made of aluminum or stainless steel and are usually made of thin plates up to 6 mm. This thickness allows the formation of multi center dished ends using a technique called hydroforming.

The density of titanium alloy is generally about 4.51g/ cubic centimeter, only 60 of steel, the strength of pure titanium is close to the strength of ordinary steel, some high strength titanium alloy exceeds the strength of many alloy structural steel. Therefore, the specific strength (strength/density) of titanium alloy is much higher than that of other metal structural materials, as shown in Table 7-1. It can produce components with high unit strength, good rigidity and light weight. At present, titanium alloy is used for engine components, skeleton, skin, fasteners and landing gear.
High thermal strength
The use temperature is several hundred degrees higher than aluminum alloy, can still maintain the required strength at moderate temperature, can work for a long time at 450500 temperature these two titanium alloys still have high specific strength in the range of 150500, and aluminum alloy at 150 than the strength decreased significantly. Titanium alloys operate at temperatures up to 500, while aluminum alloys operate below 200.
Good resistance to corrosion
The corrosion resistance of titanium alloy is much better than that of stainless steel when working in humid atmosphere and seawater medium. Resistance to pitting corrosion, acid corrosion, stress corrosion is particularly strong; Excellent corrosion resistance to alkali, chloride, chlorine organic articles, nitric acid, sulfuric acid and so on. But titanium has poor corrosion resistance to reducing oxygen and chromite medium.
Good low temperature performance
Titanium alloy can keep its mechanical properties at low temperature and ultra low temperature. Titanium alloys with good low temperature performance and very low gap elements, such as TA7, can maintain certain plasticity at -253. Therefore, titanium alloy is also an important low temperature structural material.
