| Expander mainly produces the seamless steel pipe described below
Pipe expanding machine is designed for large diameter seamless steel pipe with insufficient production capacity and incomplete specifications.The equipment is a double-cylinder or four-cylinder parallel uniform-speed pusher, and the valve table of the pump station adopts the integrated form.According to the outer diameter and length of the expanded steel pipe, the power of the medium frequency heating power supply, the thrust and stroke of the cylinder are set.
Pipe expander is composed of the following components: hydraulic pipe expander main machine, automatic loading and unloading structure, hydraulic pump station, pipe matching device, operation table, motor control cabinet, medium frequency power supply, compensation capacitor, water cable, medium frequency coil adjusting frame, reactor.Expansion system of big pipe diameter Φ interchanged 1520 mm, wall thickness 120 mm.
Steel is the main raw material of seamless hot expanding steel pipe.Steel is refined from iron.There may be other materials that can exist with steel.For example, manganese, aluminum, zirconium and so on.
The next step after the rough steel is to turn the usable steel into steel.Well, the process of making steel pipe, whether welded or seamless, begins when raw steel is cast into a more viable form.Liquid steel is made by melting iron ore and coke in a furnace.The carbon is then removed by spraying oxygen into the liquid.The molten steel is then poured into the iron mold to get the ingot.
Next, the ingot is put into a machine, where it is pressed and turned into thinner and longer sheets of steel.The thinning and elongation process continues until the required steel size is obtained.The steel is turned over, so the steel is uniform on both sides.
The last procedure is to cut the uneven end.Here, the uneven ends are cut off and the flowers are cut into shorter pieces.These billets are then further processed to make thermally expanded steel tubes.
The steel is then stretched into tubes.For seamless tubes, the main consideration is to stretch the steel and form the pipe.The billet is heated to about 1204 degrees Celsius.The steel has reached a state of easy stretching.The drawing is done with the help of a special type of drum.
The expanding machine manufactured by our company mainly produces the above seamless steel tubes, which can produce various types of steel tubes, welcome new and old customers to visit and consult.
