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.I-beam has the dual properties of high hardness and toughness materials. Compared with other engineering wear-resistant materials in China, such as various alloy steel plates, cast wear-resistant plates, cast stones, rubber, polyurethane, etc., it has irreplaceable comprehensive excellent properties.Xibangu, Spiral welded steel pipe (sy- for pile is made of hot-rolled steel strip coil as pipe blank, often warm spiral forming, double-sided submerged arc welding or high-frequency welding. It is used for foundation pile of civil building structure, wharf, bridge, etc.Plan scheme : high carbon steel with carbon content exceeding .% and alloy pipe with chromium content not less than %Lvov, Cold extrusion. This kind of processing method is more purposeful. Before the preparation of steel processing and extrusion molding, 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,XibanguHow much is the I-beam per ton, the automatic control system will be upgraded. Judged as failing.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:

Because alloy pipe is a very unique pipe fitting,XibanguHow much is a 4-point galvanized pipe, 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, 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. Material requirements Peak crackProduct survey, Frame line crackThe crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width, the more serious the disadvantages.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,XibanguHow many inches is 140 welded pipe, 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.

All the cracks occur at -mm away from the edge below the alloy pipe, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape.agent,→ compared with general section steel, it has the advantages of low cost, high precision and small residual stress. It does not need expensive welding materials and weld detection, and saves about % of the manufacturing cost of steel structure.Galvanized pipe is actually galvanized pipe. This is mainly because it increases the corrosion resistance of the steel pipe, so it is evenly coated with a layer of zinc. It can prevent the erosion of other chemicals such as and steam, and protect the steel strip. It is non-destructive and effectively prolongs its service life. Generally, the steel strip purchased is rolled into a large number by the galvanized pipe manufacturer, so pay attention to it during storage.It can withstand continuous moderate impact and can provide composite plates of various thicknessesXibangu→ compared with the concrete structure, the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - %, and reduce the structural design internal force.H-section steel belongs to high-efficiency and economic cutting profile (other cold-formed thin-wall section steel profiled steel plate, etc.). Due to the reasonable section shape, they can make the steel give more play to its performance and improve the cutting capacity. Different from ordinary I-type, the flange of H-section steel is widened, and the inner and outer surfaces are usually parallel, series and models are complete, which is convenient for settingRequirements of alloy tubes for low and medium pressure boilers
