Application characteristics of I-beamUsing alloy pipe to produce ring parts can improve the utilization rate of raw materials, and save raw materials and production and processing construction time, such as roller bearing ring throwing Nowadays, seamless steel pipe has been widely used to produce hydraulic jack sleeve.Bordraja, Welded steel mesh is aesthetically pleasing. 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.Beni,When 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.Last week, the billet in North China market showed a slight rebound trend. The billet quotation in Tangshan, the leading city, with a strong wait-and-see atmosphere in the market. Affected by the almost stagnation of festival procurement, Tangshan billet fell by yuan during the Dragon Boat Festival holiday. On the first day after the festival, although the phase snail is still running at a low level, due to the small billet resources in the market, the steel mills unexpectedly rose, and the billet market rebounded. However, due to the continuous increase of capital pressure and the downturn in the transaction of downstream finished materials, the steel plant has always maintained a cautious wait-and-see attitude to maintain stability.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.

Plan option : Martensitic chromium alloy pipe, also known as galvanized pipe, is divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing layer is thick, the coating is uniform, the adhesion is strong and the service life is long. The electroplating cost is low, the surface is not smooth, and the corrosion resistance is worse than that of hot dip galvanized pipe.The 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.Equipment maintenance,Generally, there are many passivation methods for alloy tubes,BordrajaTelephone number of welded pipe manufacturer, the common ones are high temperature passivation or sodium cyanide passivation.X-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, dead end welding of strip steel and circumferential seam. For the spiral welding of steel for the transportation of flammable general liquids, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water, wastewater, gas, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.I-beam: national standard * what is the wall thickness of I-beam

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:Development Curriculum,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, let&#;s introduce the operation steps of roll adjustment during roll change. First of all, we must replace the specification and model of the welded pipe manufacturer. Generally replace the complete set of rolls. The adjustment process of the rolls is as follows: first, draw an axis from the channel of the generator set to the import and export with stainless steel wire for adjustment, so that the holes of each frame plate are on the same axis, and the bottom line of forming ethics meets the technical standards.I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.Bordraja,The production process can be summarized as follows: pre leveling → finishing → straightening → post leveling. Flat steel / A / B steel with width of -, thickness of -,BordrajaPrice of steel bar 50 cutter, rectangular section and slightly pure edge. Flat steel can be finished steel, 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.Application scope of alloy pipe
