'bottom head'

Standard: ASME VIII-I, DIN28013 Material: GR1, GR2, GR5, GR7, GR12 Size: Customized Gr5 Titanium Dish Head Product Information Titanium dish head refers to the element used to close the end of the container to isolate the internal and external media, also known as end caps.

Standard: ASME VIII-I, DIN28013 Material: GR1, GR2, GR5, GR7, GR12 Size: Customized Gr2 Titanium Dish Head Product Information Titanium dish head is the end cap on the pressure vessel and is a main pressure-bearing part of the pressure vessel. The role played is the sealing effect. First, the upper and lower bottoms of the tank-shaped pressure vessel are made, and the second is that the pipe is at the end and is not going to extend forward. Then a titanium dish head is used to seal the pipe in the form of welding. There are blind plates and caps that are similar to the functions of titanium dish head, but those two products can be disassembled. After titanium dish head is welded, it cannot be disassembled. So the quality of titanium dish head is directly related to the long-term safe and reliable operation of the pressure vessel. Standard: ANSI/ASME, DIN, GB, EN, JIS, MSS, API, BS, AWWA, GOST etc. Grade: GR1, GR2, GR5, GR7, GR12 OD: 300-2500mm Thickness: 2-300mm Production Process: Cold Forming, Hot Forming Surface Treatment: Sand Blasting, Pickling, Coating etc. Applications: Heat Exchanger, Condenser, Pressure Vessel, Reactor, Storage Tank, Boiler, Absorber etc

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.

Product name:Titanium Pressure Vessel Hemispherical Tank Head Standard: ASME VIII-I, DIN28013 Material: GR1, GR2, GR7, GR12 etc. Size: Customized The Hemispherical Tank Head head refers to the element used to close the end of the container to isolate the internal and external media, also known as the end cover. The head of cylinder descriptors is generally a rotating shell. According to the shape of the head surface, it can be divided into convex shape, conical shape, flat shape and combined shape. Convex head refers to the head whose outer surface is convex, such as semi spherical, elliptical, dished and non folded spherical head. Some gas cylinders adopt the combined bottom head with convex face inward, which can not only ensure the strength, but also meet the needs of use. Matterial: titanium GR1, GR2, GR7, GR12 etc. Type: select suitable head types according to the requirements and effectiveness of industrial equipment, such as elliptic, butterfly, cone, ball, etc Size: generally, the height width ratio of the head is manufactured according to international standards, or can be customized according to customer requirements Scope of application: the head is widely used in petroleum, electronics, chemical industry, medicine, textile, food, machinery, construction, nuclear power, aerospace, industry and other industries.
