Using alloy pipe to produce ring parts can improve the utilization rate of raw materials, simplify the production and manufacturing process, and save raw materials and production and processing construction time, seamless steel pipe has been widely used to produce hydraulic jack sleeve.Pass designGao Wen,Galvanized pipes shall be stored in dustproof to keep clean and new . As a professional manufacturer of galvanized pipe, we have produced galvanized pipe products for many years. Welcome friends who need to buy.I-beam is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.Jaruco,Key technical characteristics of alloy pipe:c. quality inspection is carried out for alloy pipes, so that the whole process of steel pipe processing is under reasonable inspection and supervision,Gao WenTurning method of reinforcement, and the product quality is reasonably guaranteed.After determining the reasonable pickling agent and polishing solution, it is very easy to carry out hot galvanizing for relevant alloy pipes. Use 'phosphating treatment' to degrease the pipes of electrolytic machine equipment, put them into the aqueous solution with zinc salt after pickling and passivation, connect the negative level of electrolytic machine equipment,Gao WenLongitudinal welded pipe manufacturer, put them into the cold-rolled steel plate in the direction corresponding to the pipes, and connect the switching power supply, If the current flows from the positive stage to the negative stage, a layer of zinc is deposited in the pipe.
→ I-beam can be processed into T-beam, and honeycomb beam can be combined to form various section forms,Gao WenHow much is welded pipe, which greatly meets the needs of engineering design and manufacturing.Reinforcement mesh is manufactured by automatic and intelligent production line under the strict quality control of the factory. Grid size, reinforcement specification and quality are strictly controlled. The longitudinal and transverse bars of the reinforcement mesh form a network structure, so it has good bonding and anchorage with the concrete, and the load is evenly distributed, which obviously shows the seismic crack resistance of the reinforced concrete structure.Passivation treatment operation of alloy piperecommend, The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.So why is the alloy pipe easy to rust after being pickled and passivated by the software?→ I-beam can be processed into T-beam, and honeycomb beam can be combined to form various section forms, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.install,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 -, when the steel structure changes during heat treatment, that is, austenite transforms into martensite, the increase of specific volume will be accompanied by the expansion of workpiece volume, and each part of workpiece will undergo phase transformation successively, resulting in inconsistent volume growth and structural stress. Due to the change of tissue stress, the tensile stress on the surface and the compressive stress in the heart are just opposite to the thermal stress. The magnitude of microstructure stress is related to the cooling rate, shape and chemical composition of martensitic transformation zone materials.The alloy tube can be hardened by induction heating, so it has excellent rolling fatigue characteristics and corrosion resistance. Therefore, this kind of steel has been widely used as the material of rolling mill flap ball screw in rolling mill manufacturers. In addition to the excellent properties of cronidur steel, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment and its application range is expected to be further expanded.Gao Wen, Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example, when the billet section is narrow and wide I-beam is required to be rolled, when the billet is wide and small I-beam is required to be rolled, the negative rolling method can be used Spread rolling etc.In order to make the steel pipe workpiece have the required mechanical, physical and chemical properties, in addition to the reasonable selection of materials and forming processes, heat treatment process is often essential. Steel is the most widely used material in the mechanical industry. The microstructure of steel is complex and can be controlled by heat treatment. Therefore, the heat treatment of steel is the main content of metal heat treatment. In addition, aluminum, copper, magnesium, titanium and their alloys can also change their mechanical, physical and chemical properties through heat treatment to obtain different service properties. Cross rolling pass system. This pass system refers to that the two open legs of the I-beam pass are not on the same side of the waist at the same time, and the waist has an included angle with the horizontal axis.
