beam impact tubes

Hot rolled precision tube with the slab or slab continuous casting round billet as a raw material, by step heating furnace, high pressure water descaling after entering the roughing mill, roughing expected by the cutting head, tail, and then into the finishing mill, and the implementation of computer control rolling and finishing after through laminar cooling and the winder, become straight hair volume. Straight hair volume of head and tail often show tongue shape and fish shape, thickness and width accuracy is poorer, side often exists defects such as wave shape, folding, tower. The volume weight is heavier, coil diameter is 760 mm.
Precision steel tube is a kind of after cold drawn or hot rolling process of a kind of precision steel tube material. Because the product inside and outside wall without oxidation layer, under high pressure without leakage, high precision, high beam impact tubes finish, cold bending deformation, flaring, flattening without cracks, etc, it is mainly used to produce pneumatic or hydraulic components products, such as a cylinder or cylinder, welded pipe.
To pass through the cutting head and cutting tail straight hair volume, trimming and straightening, level off of multichannel time after finishing line processing, cutting board or heavy volume, again become namely: hot side impact beams rolled steel plate, flat hot-rolled coil, slitting, hot rolled precision tube, and other products. Hot rolling finishing if volume after acid pickling to remove scale and greased the hot-rolled pickling plate volumes.
Aluminium tube surface with hot dip plating or electroplating aluminum layer of welded steel pipe. Aluminium can increase steel pipe corrosion resistance, prolong service life. The purpose of the product is very wide, in addition cold drawn tubes to a general low pressure fluid such as water, oil line pipe, also used in the oil industry, such as Marine oil field oil well pipe, oil pipe, chemical coking equipment of oil heater, the condensing, exchange of coal distillation wash oil cooler for tube, and trestle pile, mining tunnel supporting frame tube, etc.
Aluminium tube common cleaning methods are as follows: first use solvent to clean steel, the surface of the organic matter removal; Rust removal and then use the tools (wire brush), remove scale, rust, loose or tilted welding slag, etc.; Using the pickling. Aluminium tube is divided into hot and cold, the plating hot dip is not easy to rust, cold plating is easy to rust.
