Correct honing tube processing

- Apr 14, 2020-

Honing pipe is a seamless steel pipe that is made of seamless steel pipe to make mechanical structure or hydraulic equipment. The steel pipe is processed by cold drawing or cold rolling. Because there is no oxide layer on the inner and outer walls, no high pressure without leakage, high finish, no deformation during cold bending, flare, no cracking, etc., it is mainly used to produce pneumatic or hydraulic products.

The layout and direction of its laying should be neat and the layers are well-defined, try to use horizontal or vertical piping, and use a level meter to detect. Longer pipelines should take measures to avoid the stress caused by the temperature expansion and contraction of the pipe.

Ø The diameter above 50mm should be cut by mechanical processing method. If you use gas cutting, you need to use mechanical processing methods to turn the tissue change part caused by gas cutting, and at the same time, you can turn out the welding groove. Except for the oil return pipe, the pressure is not allowed to be cut by the roller squeezing cutter. The cutting surface should be smooth to remove burrs, oxide scale, slag, etc.

The electrodes and fluxes used should match the pipes to be welded, and the grades must have clear basis materials, product certifications, and be within the period of use. The electrode and flux should be dried according to the product manual before use, and kept dry during use, and used on the same day. The electrode coating should be free of peeling and cracks.
