The specification of pass design I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is. The types of I-beam include hot-rolled ordinary I-beam, light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~, expressed as No. ~ No., and the inclination of inner wall of leg is : The pass system of rolled I-beam includes direct pass system, cross pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.b. The professional two-sided arc welding processing technology can complete the electric welding at a good position, which is not easy to have the disadvantages of staggered joint, welding deviation and incomplete penetration, and it is very easy to manipulate the welding quality.Aziziye, physical and chemical properties, in addition to the reasonable selection of materials and forming processes,AziziyeHow much is the price of I-beam per meter, 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.Sibiu,Alloy tube is widely used in our daily life,AziziyeHow much is a 1.5-inch galvanized pipe, which provides us with great assistance.So why is the alloy pipe easy to rust after being pickled and passivated by the software? Miscellaneous scab

Alloy pipe is a very important way and type of seamless steel pipe. Its use is relatively common. It is widely used in various engineering projects, house construction and building decoration. Its fracture will always be found in the production, That is, many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons.The multi-al combination of reinforcement mesh welding machine and reinforcement mesh row welding machine based on PLC basic control. At present, the full-automatic mesh welding machine has the characteristics of simple operation, and the relevant limit accuracy or appearance change is not easy to change.Process inspection,When we carry out different projects, we must use different raw materials, which can ensure the quality of the project. In many kinds of data, alloy pipe is widely used. In many projects, we will apply it, so it is very popular in the field. When people carry out the construction of alloy pipe project, there are many things that must be paid special attention to. Let&#;s take you to know:Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption, not occupy the natural environment, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs. Hot stamping. Fix the plan product workpiece or preformed vacancy on the rotating journal, with the wheel working pressure vacancy radial wheel. After one or several solutions, specification scope there can also be a variety of methods for the whole process of hollow thick wall rotating body products. Products manufactured by high-precision processing method have excellent physical properties, mold shell and software requirements, which are very simple, very easy to be replaced, and relatively low product cost. The processing time is not long enough, the processing capacity is not high, the total length of processing pipeline is limited, and the size of machinery and equipment is generally short.

It is a potential rolled strip steel with rectangular section for general purpose. It is very common on construction sites. Its specifications are expressed in thickness and width. At present, most of the flat steel on the market are finished steel, which can be used ready-made for components, ladders, bridges and fences. Flat steel can also be used as blank for welding rigid steel and slab for laminated thin plate.Standard requirements,Dry processing technology: after passivation treatment,AziziyeA335p92 American standard high pressure alloy pipe, parts shall be dried with air compression or hot gas, or drying treatment or air drying can be selected.There are five main guarantee measures for steel pipe welding. If these five aspects are guaranteed, the quality of galvanized pipe can also be guaranteed. The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Aziziye,Key technical characteristics of alloy pipeIt is widely used in various fields of national economic construction, such as buildings, bridges, power stations, oil drilling platforms, vehicles, highways, subways steel structure plants and large warehousesAdvantages of using I-beam: reduce maintenance cost, reduce downtime, reduce equipment capacity and increase power consumption
