Carbon steel end caps
Carbon steel end cap
End cap (casing) cap, also known as head, plug, cap, pipe cap, bulkhead, welded on the pipe end or installed on the external thread of the pipe end to cover the pipe fittings that block the pipe. It is used to close the pipeline and has the same effect as the pipe block.

| Manufacture of carbon steel pipe end cap |
Manufacturing process
Blanking (crossing)-small boards are assembled into large boards-finished products-non-destructive testing
The direction of the welding seam when the steel plates are spliced is only allowed to be radial and circumferential (this requirement may be cancelled for large pipe caps). The splicing distance should be required to be greater than 3δ and not less than 100mm (welding heat affected zone is a high-stress zone, and the chemical composition in this zone will be burned. So avoid the high-stress zone, which is related to the thickness According to practical experience, the stress attenuation length is greater than 3δ, and not less than 100mm).
For the head formed after splicing, the splicing welding seam should be 100% ray or ultrasonic inspection, and the qualified level will follow the equipment shell. The detection level and ratio of the final formed weld seam are the same as the equipment casing.
Application
The carbon steel end cap is welded to the pipe end or mounted on the external thread of the pipe end to cover the pipe fittings that block the pipe. Used to close pipelines, used in petrochemical, nuclear power, machinery, medical equipment, fertilizer, shipbuilding and other pipelines.
