2023-10-14 21:16:46Metallization: refers to the process of penetrating metal atoms into the surface layer of alloy steel pipe. It is to alloy the surface layer of steel so that the workpiece surface has the characteristics of some alloy steel. Aluminizing, chromizing, boronizing, siliconizing and so on are commonly used in production.Heating surface pipes, economizers, superheaters, reheaters, pipes for petrochemical industry, etc. for high-pressure boilers (working pressure is generally above MPa and working temperature is between ℃ ~ ℃)Panama, Tungsten; can improve the red hardness and thermal strength of steel, and can improve the wear resistance of steelCarburizing: 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,PanamaGh3128 alloy pipe, the part of the workpiece can maintain the toughness and plasticity of low-carbon steel.Saint Gallen,The wear resistance, fracture toughness, impact toughness and bending strength under different process conditions were compared, and then the heat treatment process of GCrMo was determined. Development and application of ZYS- bearing damping and antirust oil. Bearing is a new type of multial damping and antirust oil. It takes refined mineral oil as the base oil and is equipped with various additives such as antirust and antifriction. Through comparison test, matching test with lubricating grease and user test, it is proved that ZYS- bearing damping and antirust oil has outstanding damping effect and good antirust lubrication performance. The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard. Frame line crack
The sodium cyanide passivation treatment of alloy pipe can be divided into four categories. Before passivation treatment, the surface of alloy pipe shall be clear of oil stains, pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned, and the workpiece of alloy pipe products can be infiltrated into aqueous solution. The passivation treatment of the alloy tube in sodium cyanide transforms the surface layer into a very thin passivation treatment film, which determines that the color of the surface layer has no change before and after passivation treatment, and the reproducibility of the solution is good.However, compared with plastics, these pipes, like other metals, remain stable and will not be affected by high temperature.Aiming at the connective tissue and texture produced in stainless steel plate Position and other crystal defects are generally removed by heat treatment processes such as quenching or quenching. The effect of quenching is to optimize the crystal, eliminate structural defects, reduce strength, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe, quenching machinery and equipment cannot be lacked. Therefore, the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness, reduce the product cost and reduce the quenching process,PanamaSC embedded threading welded pipe, it will eventually lead to bad harm to the product quality.Excellent serviceWhat is the purpose of flat steelWhat is the stainless steel passivation of alloy pipe?Generally,PanamaWhat is the price of 273 seamless pipe, the process of pickling and passivation will be carried out for alloy pipes, but the alloy pipes after pickling and passivation are very easy to rust. Therefore, there is no harm to carry out hot galvanizing in the middle and later stage.
It can withstand continuous moderate impact and can provide composite plates of various thicknessesPriceAlloy pipes can be used for heating (cooling) projects.The reinforcement mesh is used for embankment protection or for the protection of the whole riverbed and river bank, which is more suitable for the river channel with relatively gentle original bank slope. Taking the design dry water level as the boundary, the upper part is slope protection works and the lower part is foot protection works.→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.Panama,Precision cold rolling of small and medium-sized bearing sleeves with alloy tubes can greatly improve material utilization, bearing performance and service life. This paper systematically introduces the development of high quality cold drawn bearing steel pipe and its application in bearing.

The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time
