Heating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃);H-shaped steel groove is deep and thick, and can withstand forces in two directions.Beiwan, For the surface mesh of the height difference plate, when the height difference is ≤ mm, the surface mesh can be bent and installed; when the height difference plate is more than mm, the surface mesh should be disconnected at the place with height difference and put into the beam respectively. The anchorage length of the reinforcement is required for the reinforcement to extend into the beam. Remove defective pipes within the allowable length.Merouana, in leg width and in waist thickness.The core of C-section steel is the structural system of braced frame. More than half of such senior managers in China are the former. Unfavorable to earthquake resistance. Hydraulic power, generally about KW, which is similar to the plate shearing and bending machine. The general control process is complex, and PLC control is mostly used.→ wide flange and large lateral stiffness. Strong bending resistance.

The pickling agent in the pickling process contains many acidic substances, including hydrochloric acid, etc.,BeiwanHow much is a welded pipe, which has strong corrosion and reduction, and the temperature of etching substances is relatively high. Therefore the corrosion resistance of alloy pipes is specified higher.Blanking shall be carried out according to the design and site, and then the groove shall be made with a grinder with a groove angle of ° ~ °. Fix the processed pipe on the support, and the gap between the two pipes is mm ~ mm, and then weld.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.Excellent service,Because alloy pipe is a very unique pipe fitting, we must use appropriate methods to carry out installation in the case of installation, so as to ensure the performance index of the data. Generally, when installing alloy pipes, we will use some flanges and elbows to fix them, so as to ensure that the raw materials can be fixed very well. Therefore, when we carry out use, we must ensure the quality of flanges and elbows, so as to ensure the actual effect of alloy pipe assembly. If there are instrument panel components that must be assembled on the pipeline, they must be installed together.I-beam is a long strip steel with groove section, which belongs to carbon structural steel for construction and machinery. It is a section steel with complex section, and its section shape is groove shape. China&#;s imports of I-beams are greater than its exports. The main producing areas are Tangshan Iron and steel, Baotou Iron and steel, Shangang, huangte Maanshan Iron and steel, Xuanhua Iron and steel Japan iron and steel, etc.Dry processing technology: after passivation treatment,Beiwan12Cr2MoWVTiB alloy pipe, parts shall be dried with air compression or hot gas, or drying treatment or air drying can be selected.

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.Inspection basis,BeiwanHigh pressure alloy pipe,Due to the unique performance of I-beam, I-beam has successfully solved the problem of serious equipment wear in many industries.Idler pipe: it is used for electric welding steel pipe of idler of belt conveyor. It is generally made of Q, QA, B steel and steel, with a diameter of -mm. There are certain requirements for pipe tortuosity, end face straightness with the center line and ovality. Generally, water pressure and flattening tests are carried out.What should we pay attention to in the production of alloy pipeBeiwan, Hot push hole diameter. More sensitive applications and facilities of such methods require simplicity, low cost, easy maintenance, durable economic development and convenient product specification transformation. For example, the production of large diameter must be grooved pipe, elbow and similar products. You only need to add some spare parts. The expansion method of hot push can be used to process and manufacture large-diameter, and can not exceed the working capacity of thick wall pipes of machinery and equipment.I-beam is an economic section high-efficiency profile with more optimized section area distribution and more reasonable strength weight ratio. It is named because its section is the same as the English letter 'H'. 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, the wave rolling method can be used; for example, when the billet is wide and small I-beam is required to be rolled, the negative rolling method can be used Spread rolling, etc.
