Durable material - The Tube Expander Tool Kit uses heat-treated steel for maximum strength and long service life. The swivel joint is made of chrome-plated alloy steel to reduce friction and wear. Easy to use - Choose the correct tube head and attach it to the tool to perform high-quality pipe bending and flare work. - The alloy steel cutting wheel blade is corrosion resistant, and the length of the tube expander tool kit remains unchanged when used in restricted areas. Portable and organized - Cutting diameter range: 3 to 19 mm (0.12 to 0.75 inches). - Includes a carrying case with handles for easy transport, safe storage, and quick organization. Applications - The tube expander tool kit is commonly used in the manufacture and maintenance of pressure vessels such as condensers, coolers, heat exchangers, boilers, and other pressurized equipment in cooling, petrochemical, power, shipbuilding, metallurgy, and related industries.
