Pipe Forming Technology For ASTM A333 Seamless Steel Pipe

1. Hot extrusion method: Before the extrusion, it is necessary to carry out machining pretreatment of the blank. When the pipe fittings with a diameter of 100 mm or less are extruded, the equipment investment is small, the material waste is small, and the technology is relatively mature.

2. Hot spinning method: The ASTM A333 Seamless Steel Pipe is to fix the flat blank or the pre-formed blank to the rotating mandrel, and apply pressure to the blank by the rotating wheel, and the rotating wheel is simultaneously fed axially, after one or more processing. , a process for obtaining various thin-walled hollow rotor products.

3. Hot piercing and rolling method: Hot piercing and rolling is mainly based on longitudinal rolling and cross rolling. Longitudinal rolling and rolling is mainly limited to dynamic mandrel rolling mill rolling, small frame limiting mandrel rolling mill rolling, three-roller limiting mandrel rolling mill rolling and floating mandrel rolling mill rolling.

4. Hot push-expanding method in China Carbon Steel Pipe Factory: It is simple to push and expand the diameter equipment, low in cost, convenient in maintenance, economical and durable, and flexible in product specifications. If you need to prepare large-diameter elbows and other similar products, you only need to add some accessories. It is suitable for the production of medium and thin wall thick large diameter seamless steel pipe, and can also produce thick wall pipe which does not exceed the equipment capacity.
