Product Description
Cold-drawn structure pipe hot-rolled steel coil as raw material, after pickling to remove the oxide skin, cold continuous rolling, the finished product is rolled hard coil, because of continuous cold deformation caused by cold hardening, the strength and hardness of rolled hard coil increase, toughness and plastic index decline, so the stamping performance will deteriorate, can only be used for simple deformation parts. Hard roll can be used as raw material in hot dip galvanizing plant because hot dip galvanizing units are equipped with annealing line. Rolled hard coil weight is generally 6~13.5 tons, coil diameter is 610 mm.
The surface quality, appearance and dimensional accuracy of cold-rolled Structural Pipe are better than that of hot-rolled structural pipe, and its product thickness is right-rolled thin to about 0.18 mm, so it is favored by the majority of users. The deep processing of products based on cold rolled steel coil has become a high value-added product. Such as electric galvanizing, hot dip galvanizing, fingerprint galvanizing resistance, Color Coated Steel Coil and vibration reduction composite Steel Plate, PVC laminated steel plate, etc., so that these products have beautiful appearance, high corrosion resistance and other excellent quality, has been widely used. Cold rolled steel coils must be finished after annealing, including cutting head, tail, trimming, leveling, leveling, rewinding, or longitudinal shear plate, etc. Cold-rolled products are widely used in automobile manufacturing, home appliances, instrument switches, construction, office furniture and other industries. The weight of each bale after steel bale is 3~5 tons. The weight of flat subreel is generally 3~10 tons/reel. Inner diameter of steel coil 610 mm.
Hot rolling structure pipe continuous casting slab or preliminary rolling slab as raw material, through the stepping furnace heating, high pressure water descaling into roughing mill, roughing mill through cutting head, tail, and then into finishing mill, the implementation of computer control rolling, after the final rolling laminar cooling and coiler winding, straight coil. The head and tail of straight hair curl are often tongue and fishtail, and the thickness and width are poor. The edge often has defects such as wave shape, hem and tower shape. Its coil weight is heavy, the inner diameter of the steel coil is 760mm. (General pipe industry like to use.) The straight hair coil is processed by cutting the head, cutting the tail, cutting the edge and many times of straightening, leveling and other finishing lines, and then cut plate or rewinding, that is, hot rolled steel plate, flat hot rolled steel coil, longitudinal cutting strip and other products. Hot rolled finishing roll is formed by pickling and oiling after removing oxidation skin. The product has a partial replacement of cold - rolled structural pipe trend, moderate price, favored by the majority of users.

| Application |
For high, middle, low pressure boiler and pressure purpose. Used in heat exchangers and boilers to provide highly energy efficient means of heat transfer. The presence of the internal rifling induces centrifugal forces in the mass flow thereby separating the water from the steam fraction and forcing the water towards the tube wall.
