Using alloy pipe to produce ring parts can improve the utilization rate of raw materials, and save raw materials and production and processing construction time, such as roller bearing ring throwing Nowadays, seamless steel pipe has been widely used to produce hydraulic jack sleeve. Remove defective pipes within the allowable length.Kakani, The surface of hot-dip galvanized parts is bright and beautiful.Alloy tube is widely used in our daily life,Kakani6. How many kilograms per meter of sub welded pipe, which provides us with great assistance.Anadara,The delivery length of I-beam is divided into fixed length and double length, and the allowable difference is specified in the corresponding standards. The length selection range of domestic I-beam is divided into -, - and - according to different specification numbers. The length selection range of imported I-beam is generally -.I-beamH-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange, and the second is that the inner surface of the flange has no inclination, and the upper and lower surfaces are parallel. The section characteristics of H-beam are obviously better than those of traditional I-beam, channel steel and angle steel.

The defects can be removed by grinding with sand wheel, it has strong corrosion resistance.After the passivation treatment of alloy pipe, it is clearly proposed that water cleaning shall be carried out immediately after the aqueous solution, ~ times of water cleaning, and then chromic acid closed solution shall be carried out. Chromic acid solution must be carried out h after the subsequent water cleaning of metallographic structure and austenitic alloy pipe. Chromic acid aqueous solution (mass ratio) is % ~ %, the solution temperature is ~ ℃, Cold extrusion. This kind of processing method is more purposeful. Before the preparation of steel processing and extrusion molding, when the extrusion molding is used for mm diameter pipe fittings, the investment of machinery and equipment is less, so the raw material consumption is also very small, and the technology is relatively perfect. Once the tube size is increased, the cold extrusion method must have large cargo capacity and high-power machinery and equipment. Therefore, the automatic control system will be upgraded.I-beam features: the content of chromium carbon alloy is -%,KakaniHow much is the two inch galvanized pipe? It’s 6 meters,Kakani15cr1mov alloy pipe, the hardness of chromium carbide alloy is V, and the macro hardness is - HRC The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.

Carburizing: carburizing is the process of penetrating carbon atoms into the surface layer of steel. It also makes the low-carbon steel workpiece have the surface layer of high-carbon steel, and then after quenching and low-temperature tempering, the part of the workpiece can maintain the toughness and plasticity of low-carbon steel.Fair price,Function of I-beam: where is I-beam mainly used? The weight of seamless pipe is light and its weight is only one fifth of that of anti steel. Miscellaneous scabKakani,The shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm. Frame line crackI-beam is widely used
