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.H-shaped steel groove is deep and thick, and can withstand forces in two directions.Colcha , According to the diameter of the pipe, the pipe with small diameter can only be welded on one side and the technician can drill into the pipe to weld on both sides. Single side welding requires the welder&#;s technology, which can be formed by welding two on one side. Through the steel ball test it can ensure that the cross-sectional area passing capacity and weld formation meet the design requirements. Remove defective pipes within the allowable length.Milbur Haas, the moment of inertia of the two main axes of the section is quite differentDue to the relatively high and narrow section size of ordinary I-beam and light I-beam, 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.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,Colcha Wholesale price of high frequency welded pipe, manufacturing and key marketing of alloy pipe, That is, and the zinc layer is separated from the steel pipe substrate. The zinc layer is very thin. The zinc layer is simply attached to the steel pipe substrate and is easy to fall off. Therefore, its corrosion resistance is poor. In new homes, it is forbidden to use cold galvanized pipes as water supply pipes.Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materialsDirect labor,It 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 warehousesAll 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.The finished product has smooth surface, low friction coefficient, flatness error + / - mm / m length, wear resistance and maximum temperature of ℃

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.Professional is king,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,Colcha High pressure alloy pipe 12Cr1MoVG, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation,Colcha Price list of I-shaped steel, 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.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.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.Colcha , 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 macroeconomic orientation is vertical to the cold rolling orientation
