Steel products refer to solid straight steel products with a certain section shape and size, including wire, profile and plate, which are formed by plastic processing except pipes. It can be divided into hot rolling, cold bending, cold rolling, cold drawing, extrusion, forging, hot bending, welding and special rolling according to the production method. It can be divided into railway, shipbuilding, mining, structure and construction according to its use. According to the material can be divided into carbon steel, alloy steel and stainless steel. At the same time, these steel products can be reprocessed to form semi-finished products or finished products to meet special requirements. We can according to the customer's different needs, according to the drawings or samples for reprocessing production.
Stainless steel tube is a hollow long strip steel made of stainless-steel material. Because of its excellent corrosion resistance, it is mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial transportation pipelines and mechanical structural components. In addition, when the bending and torsion strength are the same, the weight is light, so it is also widely used in manufacturing mechanical parts and engineering structures, but also commonly used in the field of furniture decoration. Stainless steel pipe is divided into seamless pipe and welding pipe according to the production mode, seamless steel pipe can be divided into hot rolling pipe, cold rolling pipe, cold pulling pipe and extrusion pipe, etc., cold pulling and cold rolling is the secondary processing of steel pipe; welding pipe is divided into straight welding pipe and spiral welding pipe. Stainless steel pipes can be divided into round tubes and different tubes according to the cross-sectional shape. The form tubes have rectangular tubes, rhomboid tubes, ellipse tubes, hexagonal tubes, octagonal tubes and various cross-sectional asymmetric tubes. It can be divided into Austenitic Stainless Steel Tube Ferritic Stainless Steel Tube Martensitic Stainless Steel Tube and Duplex Stainless Steel Tube by the type of stainless steel.
Hollow Section steel Tube is the general name for the steel pipe other than thecircular steel pipe. Such as square, rectangle, oval,elliptical, cone, trapezoidal, spiral, etc. Different steel pipe can more adapt to the particularity of use conditions, save metal and improve the labor productivity of parts manufacturing. It is widely used in aviation, automobile, shipbuilding, mining machinery, agricultural machinery, construction, light textile and boiler manufacturing. The methods of producing different pipes are cold pulling, electric welding, extrusion and hot rolling, etc. Compared with the round tube, the different tubes generally have a larger moment of inertia and cross section modulus, and have a large bending resistance and torsion resistance, which can greatly reduce the structural weight and save steel.
The Cold Extrusion Machine is made up by a hydraulic Clampy with Cold Pressing Dies and Hydraulic Oil Pump. The features of this technology: 1.Strong intensity connector, stable and reliable; no specific requirements on the weld ability of the rebar; 2.Only needs 1-3m to stamp each connector, which is about ten times faster than ordinary welding; 3.Only 1-3 kw power of oil pump , which is not limited by power capacity, has flexible structure and suitable for operation on several machines; YJ650 stamping equipment 4.No flammable gases, not affected by rainy or cold weather; 5.Relieve congestion of the connecting point, facilitated concrete pouring; 6.No professional and experienced worker needed, able to connect changed steel bar of different diameters; 7.Save 80% of connector steel consumption. The technology is assessed by the Ministry of Construction as "world advanced, high quality, high efficiency, safe, and economical thick diameter distorted steel bar connection technology which can be widely used in the construction industry."

Advantages: Bar-break feature guarantees fully ductile elongation. No reduction of the bar cross-section area. Material of the rebar coupler is No.45 steel. Working principle: 1,First,We use GQ50 rebar cutting machine to splice up the end of rebar. 2,Secondly,we use Upset Forging Parallel Thread Machine (BDC-Auto1 Machine) to forge the end of rebar. 3.Third, we use Parallel Thread Cutting Machine (LW-I500 Machine) to thread the ends of the rebar which have been forged. 4.Fourth,an upsetting coupler is used to link the two ends of rebar in parallel thread.
