Process characteristics of carbon steel pipe caps

Material selection, tube cap selection of appropriate steel plate, with template marking with oxyacetylene flame cutting, clean the iron oxide and gas cutting splashes and other residues on the board, and the raw materials of the furnace, batch number and pipe fitting specifications, project name, number identification.

Tube cap pressing forming: the billet is put into the heating furnace, the heating rate above 400℃ is less than 200℃/h, heating to the technical requirements of the temperature, and insulation.

Put the heated billet into the adding mold (the inner surface of the mold should be evenly coated with graphite powder) to make the billet concentric with the mold in the circumference.

Start the hydraulic system to ensure that the pressure is greater than 8MPa.

The billet temperature was measured by infrared thermometer at the beginning of pressure.

During the pressing process, the circumferential pressure balance is maintained.
