Central tube
Our company’s central tubes are manufactured using a patented process that combines laser cutting with composite welding. They feature precise dimensional accuracy, tight gap 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.
