The honing pipe is made of seamless steel pipe. Because the inner and outer walls of the steel pipe have no oxide layer, withstand high pressure without leakage, high finish, cold bending without deformation, flaring, flattening and no cracks. Hydraulic products.
The laying arrangement and direction of the honing pipe should be neat and the same, with clear layers. Test with a spirit level. For longer pipelines, measures must be taken to prevent stress caused by temperature expansion and contraction of the pipe.
The honing pipes with a diameter of more than 50mm should generally be cut by mechanical processing methods. If gas cutting is used, a mechanical machining method must be used to remove the structural changes caused by the gas cutting, and the welding groove can also be turned out. Except for the oil return pipe, the pressure is not allowed to be cut by the roller squeeze cutter. The cutting surface of the pipe must be smooth, clear of burrs, oxide scale, slag, etc.
The electrode and flux used in the honing pipe should be matched with the welded pipe material, and its brand must have clear basis information, have product certification, and be within the effective use period. 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.
