Half Round Tube Shield Half Round Tube Shields by Ladhani Metal Corporation are precision-formed protective components used to shield boiler tubes, superheaters, and heat exchangers from erosion, scaling, ash impact, and corrosion. Commonly applied in power plants, waste heat recovery units, and industrial heating systems, these shields help prolong tube service life and maintain consistent thermal performance. Their half-round design ensures easy installation over exposed tube surfaces and provides dependable coverage in harsh gas flow zones. SS 310 Half Round Tube Shield for LTSH Tube The SS 310 Half Round Tube Shield is fabricated from high-temperature austenitic stainless steel grade 310. Known for its high chromium and nickel content, SS 310 offers excellent oxidation resistance, superior thermal stability, and strength under prolonged heat exposure. This makes it ideal for Low Temperature Superheater (LTSH) applications, where tubes are vulnerable to erosion, ash buildup, and gas-phase corrosion. The shield is precisely shaped to match the outer curvature of LTSH tubes, enabling effective surface protection in relatively low-temperature flue gas environments. The Low Temperature Superheater (LTSH) is a section in a boiler where saturated steam from the steam drum is superheated to a moderately higher temperature before entering the high-temperature superheater stages. Positioned in areas with relatively lower flue gas temperatures, the LTSH helps improve thermal efficiency and reduces moisture content in steam. Due to constant exposure to abrasive flue gases and ash, LTSH tubes are prone to wear and require protective shielding, such as half round tube shields, to extend service life. Ladhani Metal Corporation is a leading manufacturer, supplier, and exporter of SS 310 Half Round Tube Shields for LTSH tubes, offering high-performance protection in demanding thermal conditions.

Titanium sheet metal are commonly used in today's manufacturing industry, and the most commonly used grades are 2 and 5. Grade 2 titanium Grade 2 is commercial pure titanium used in most chemical processing plants and can be cold formed. Ultimate tensile strength of grade 2 plates and sheets up to 40,000 psi and above. Grade 5 titanium Class 5 is an aerospace class that does not allow cold molding and is therefore used more often when molding is not required. Grade 5 aerospace alloys have ultimate tensile strength of 120,000 psi and above. Usually the purpose of using Titanium sheet metal is to really approximate the final size of the part being manufactured. The material is processed to the nearest size of the required parts and the grain structure of the finished product is more uniform. Titanium plates are often used as insulation because titanium prevents heat from being transferred to the rest of the assembly. The titanium plate and titanium plate are bulletproof and provide good protection for the driver during the race. Application example: in addition to the use of industrial pure titanium manufacturing parts, a large number of titanium alloy is used. It is increasingly widely used in aerospace, aerospace, chemical, shipbuilding and other industrial sectors, manufacturing gas turbine components, the production of prosthetic devices and other biological materials

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.
