Internal Expansion Pipe Beveling Machine - ND Series
ND Series Internal Expansion Pipe Beveling Machine
The ND series internal expansion pipe beveling machine is a portable pipe end preparation tool for industrial pipeline welding preparation. It is mainly used for pipe end beveling, end facing, welding preparation and on-site repair work. The machine uses an internal expansion clamping structure, supporting and positioning from the inner diameter of the pipe. After clamping, it can perform stable pipe end machining, making it suitable for on-site installation, pipeline prefabrication and shutdown maintenance projects.
According to different pipe diameter ranges, the series includes ND-80-T, ND-120-T, ND-150-T, ND-252, ND-352, ND-426 and ND-630 models, covering a pipe processing range from 28mm to 600mm. Users can select the proper model according to pipe diameter, wall thickness, material and available working space. The machine can process V-type, I-type and U-type bevels, with tool angle options including 30°, 37.5°, 60°, 0° and internal bevel 15°.
The ND series internal expansion pipe beveling machine is suitable for carbon steel, stainless steel, alloy steel and other metal pipes. It is widely used in petrochemical pipelines, natural gas pipelines, power plant maintenance, boiler pipelines, pressure vessels, shipbuilding, food, pharmaceutical, water treatment and industrial pipeline installation. Compared with manual grinding, the machine helps improve bevel consistency, reduce on-site finishing time and improve pipe end preparation quality before welding.
Internal expansion clamping structure, positioned and supported from the pipe inner diameter. Suitable for pipe end beveling, end facing, welding preparation and on-site maintenance. Includes multiple models: ND-80-T, ND-120-T, ND-150-T, ND-252, ND-352, ND-426 and ND-630.
