What sharp concept is shaped tubes [1] shaped pipe, rectangular tube, square tube pointed concepts: shaped steel tubing, Binzhou hexagonal steel pipe, rectangular tube, square tube conventional welding stainless steel rectangular tube, hexagonal tube, usually a Turkish first roll with a few square rectangle rolls to produce. Production depends mainly on the flat roll rolling integer, since the flat roll is a two-roll formal structure, there is a rectangular tube corners of the roll gap and the corner unequal stress state inconsistencies, resulting in the four corners of the rectangular tube is not ranging tip, R = 1.2t, rectangular tube outer foot radius, f is the thickness. Although compliance with the relevant corporate standards, but not high-quality products to meet user requirements. The new design uses a Turkish head of four-high rolling integer, since the Turkish head filled with the same four-roll structure, the four corners of the roll gap equal to the corners of the stress state of the same, when the rolling force is large enough, the corners plastically deformation of the metal to fill the corners of the outer surface of the tube to form a line of intersection between the plane and the arc - that sharp, steel storage and storage: keep the warehouse clean, reinforcing material conservation 1) material in storage before to pay attention prevent rain or mixed with impurities, which has been exposed to rain or soiled materials to their nature in different ways wipe, such as high hardness available wire brush, low hardness with a cloth, cotton and other items 2) Material storage after Always check if rust should be removed rust layer 3) general steel surface cleared after the net, do not oiled, hex steel pipe, but the high-quality steel, alloy steel sheet, thin-walled pipe, steel pipe, etc., rust after its inner and outer surfaces coated with anti-rust oil before storage is required 4) should not be long-term storage after more serious steel corrosion, rust should be used as soon as possible Binzhou hexagonal steel, hexagonal pipe specifications, the virtues of Industry (certified merchants) by the virtue Liaocheng Industry Limited.
