How to handle the port of large-caliber thick-walled seamless steel pipe

The newly-produced large-diameter thick-walled seamless steel pipe ports will be rough, such as burrs, burrs and debris. The overall sensory effect of large-caliber thick-walled seamless steel pipes will have a big impact, so this will require us to handle them.

The ports of large-caliber thick-walled seamless steel tubes may have such a residue. We must handle them properly at this time. Large-diameter thick-walled seamless steel pipe spacing should use fine-tooth saws, cutting knives or special cutting machine. When breaking the pipe, the nozzle should be flat and perpendicular to the axis of the pipe.

At the end of the socket, the medium plate is used to chamfer the nozzle. The chamfer angle is 10°-30°. Before the large-caliber thick-walled seamless steel pipe is connected, the sand and dirt on the inner side of the socket and the outer side of the socket are connected. Water stains are scrubbed and clean. If there is oil stain, use a clean rag to wipe with a detergent.

The treated large-diameter thick-walled seamless steel pipe ports have been greatly improved, and the burrs and burrs have been eliminated. We can also see the change in appearance.
