Description

Technical Field

[0001] The present application relates to the field of steel pipe transportation equipment, and in particular to a forklift fork device. Background Art

[0002] Carbon steel pipe is made of steel ingot or solid round steel through perforation into rough tube, and then hot rolled, cold rolled or cold drawn. Carbon steel pipe plays an important role in my country's steel pipe industry. The bending of carbon steel pipe is achieved by bending after heating. In this process, the hot bending temperature range of carbon steel pipe is 1050-900℃. This temperature range ensures that the carbon steel pipe can achieve sufficient plasticity after heating, so that it is easy to bend without breaking or cracking. After the production of carbon steel pipe is completed, several steel pipes are usually bundled together for transportation.
