The internal bore cladding of 12-meter ultra-long pipes with a small internal diameter of 76 mm has long been a technical challenge in the industry. Due to the length of the pipe and the narrow internal space, traditional processes are prone to issues such as uneven coating, peeling, and faulting. These methods fail to achieve high-precision, stable cladding for the entire pipe, which has long restricted the quality upgrading of high-end ultra-long pipes.
To address this industry pain point, our R team has successfully overcome core technical bottlenecks such as powder feeding in ultra-long deep holes, optical path stability, and full-domain gas shielding through repeated experimentation and process optimization. The new internal bore cladding technology for pipes enables uniform cladding of the entire 12-meter internal wall without faults, pores, or impurities. The coating is tightly bonded to the pipe substrate and remains firm without peeling, completely resolving various quality defects of traditional processes and significantly improving the stability of the finished product.
This technology supports customized cladding with various alloy materials, including nickel-based, iron-based, and cobalt-based alloys. It significantly enhances the wear resistance, corrosion resistance, and high-temperature resistance of the internal pipe walls, effectively extending the service life of the pipes. Compared to processes such as electroplating and traditional overlay welding, our internal bore cladding technology offers minimal workpiece deformation, high precision, and zero pollution. It complies with green production standards and can effectively help enterprises reduce costs related to pipe replacement, equipment maintenance, and downtime losses.
