Internal components of a fluidized bed reactor
Our company provides the design and fabrication of various reactor internals.
This product series includes: reactor center tubes, sector-shaped cylinders, internal and external grids for regenerators, top conical sections, sealing cover plates, and more.
The products are widely used in catalytic reforming, styrene production, ammonia synthesis, propane dehydrogenation, and other process units.
Our company’s central tubes are manufactured using a patented technology that combines laser cutting with composite welding. They feature precise dimensional accuracy, tight seam tolerances, high‑strength mesh‑weld joints, and the absence of longitudinal welds. Electromagnetic welding represents a groundbreaking welding concept that addresses the issue of longitudinal weld cracking under high‑temperature operating conditions—problems inherent in conventional resistance‑welding processes—thereby significantly extending the service life of the central tube. These products are widely employed in process units such as catalytic reforming, styrene production, ammonia synthesis, and propane dehydrogenation.
Our company manufactures V‑shaped wire mesh fan‑shaped tubes and perforated plate fan‑shaped tubes in a wide range of sizes. These products feature high strength, excellent surface finish, superior precision, and smooth, even circumferential welds. The V‑shaped wire mesh is laser‑processed for precise gaps, while the perforated plates exhibit uniform spacing and even distribution. During production, advanced photogrammetric instruments are employed to ensure outstanding straightness and consistent product quality. These components are widely used in catalytic reforming, ammonia synthesis, and other process units.
Our company manufactures regenerators featuring inner and outer mesh cylinders that are fabricated using laser cutting and specialized composite welding, resulting in seamless cylindrical structures. These units boast a seamless design, superior resistance to thermal stress at high temperatures, exceptional dimensional accuracy, and precise gap tolerances. The inner mesh exhibits excellent surface finish and is constructed as an integral monolithic structure. The outer mesh can be processed into large-diameter seamless cylinders with diameters approaching four meters, while maintaining outstanding cylindricity, straightness, and reliable long-term operational performance. These products are widely employed in catalytic reforming, styrene production, ammonia synthesis, propane dehydrogenation, and other process units.
The V‑shaped wire mesh assembly is welded using laser technology, ensuring high precision in mesh‑wire spacing and robust weld strength. All structural components are cut and formed by laser machining, resulting in a fully assembled structure with exacting dimensional accuracy. Under high‑temperature operating conditions, no deformation or leakage occurs.
The sealing cover plate is laser‑cut and formed. The individual modules exhibit excellent interchangeability, and the assembled structure boasts precise overall dimensions, ensuring ease of installation and reliable performance.
The pipeline connector is primarily used for the rapid connection of catalyst feed lines in units such as continuous reforming and propane dehydrogenation. It offers excellent sealing performance, lightweight construction, compact dimensions, simple disassembly and assembly, and robust durability.
Our company can employ laser processing to fabricate seamless outer mesh cylinders with diameters exceeding 3,500 mm. The V‑shaped wires and support rods are joined by laser welding, ensuring high precision in mesh‑wire spacing and robust weld strength. The seamless design effectively prevents longitudinal welds from cracking under high‑temperature conditions, thereby guaranteeing the reactor’s long‑term, reliable, and stable operation.
