I-beam has wide flange, thin web, many specifications and flexible use. It can save metal by % ~ % when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge end is at right angles, it is easy to assemble and combine into various components, which can save about % of the welding and riveting workload, greatly accelerate the construction speed of the project and shorten the construction period.I-beam can be divided into four types according to shape: cold-formed equal edge I-beam, cold-formed unequal edge I-beam, cold-formed inner crimping I-beam and cold-formed outer crimping I-beam.Catano Straight seam electric welding steel pipe (yb- is a steel pipe whose weld is longitudinally parallel to the steel pipe. It is usually divided into metric welded steel pipe, etc.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.San-Jose-Pinula,Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, so it can only be directly used for members bent in the plane of their web or form lattice stressed members.Due to the relatively high and narrow section size of ordinary I-beam and light I-beam, the moment of inertia of the two main axes of the section is quite different, which makes it very limited in the scope of application. The use of I-beam shall be selected according to the requirements of design drawings.d. All machines and equipment in a production line can connect with the software of the computer data collection system to complete the timely transmission of data information and the performance parameters in the production process are monitored by the central control room.

At the same height, light I-beam has narrower legs, thinner waist and lighter weight than ordinary I-beam. No. - is large I-beam, and No. - is medium I-beam. Imported I-beam shall be marked with actual specifications, dimensions and relevant standards.Precautions for galvanized pipe storageI-beamWelcome to inquire,In order to make the welded pipe have the required mechanical, physical and chemical properties, in addition to the reasonable selection of materials and forming process, heat treatment process is often necessary. In addition, the mechanical, physical and chemical properties of aluminum,Catano 12crmovg alloy pipe, copper, magnesium, titanium and their alloys can be changed by heat treatment to obtain different service properties.Alloy tube is widely used in our daily life, which provides us with great assistance. So what industries are alloy tubes applied to? Let&#;s follow the steps of all manufacturers and have a look together: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.

What is the stainless steel passivation of alloy pipe?consumption,The utility model has the advantages that the axial force of the roll is small, the axial movement is small, the working inclined plane is not required, the pass occupies a small length of the roll body, and more passes can be matched under the condition of a certain length of the roll body.The use of hot dip galvanizing has expanded with the development of industry and agriculture. Therefore, hot-dip galvanized products have been widely used in industry (such as chemical equipment, petroleum processing,Catano How much is the welded pipe per meter, marine exploration, metal structure power transportation, shipbuilding, etc.), heating room), construction (such as water and gas transportation, wire casing, scaffold, house, etc.), bridges, transportation, etc. because hot-dip galvanized products 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.Catano , Peak crackIt can withstand continuous moderate impact and can provide composite plates of various thicknessesWhen selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size. I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams.
