PerikoLongitudinal welded pipe manufacturerIntroduction of performance characteristics

Because all parts of I-beam are arranged at right angles, I-beam has the advantages of strong bending resistance, cost saving and light structural weight in all directions, and has been widely used. The inner and outer sides of the flange of the I-beam are parallel or close to parallel, and the end of the flange is at a right angle, so it is named parallel flange I-beam. The web thickness of I-beam is smaller than that of ordinary I-beam with the same height of web, and the flange width is larger than that of ordinary I-beam with the same height of web, so it is also named wide edge I-beam.The high-temperature passivation treatment of alloy pipe is to obtain the passivation treatment film by heating in the heat treatment equipment. Before passivation treatment, the surface layer of parts must be removed to remove waste. At a higher temperature, the passivation treatment film can be obtained according to the transformation temperature and time. The hue of passivation treatment film can refer to the annealing color of alloy pipe, and the main parameters of ambient temperature and time of heat treatment process can be selected.Periko,According to the historical records of the recent four years, and generally entered a wave of upward trend in the first quarter. However, zinc prices continued to decline in the first quarter of , and showed a trend of accelerating the decline day by day. There are two key reasons for the beginning of this year. First, the vicious change of the real estate industry has led to a rapid decline in the growth rate of China&#;s consumption of galvanized pipe and seamless steel pipe, and even a contraction month on month; Secondly, the blind expansion of galvanized pipe factory confused the sense of rhythm of supply and demand balance.→ 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.Wau,Due to the relatively high and narrow section size of ordinary I-beam and light I-beam, the moment of inertia of the two main axes of the section is quite different, 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.Requirements of alloy tubes for low and medium pressure boilersGreatly reduce the environmental pollution caused by abrasion, damage and blanking,PerikoHow much is 40x40 galvanized pipe per meter, and increase the labor cost of material cleaning

According to the theory of steel structure, the I-beam flange should be stressed, that is,PerikoHow much is a meter of DN100 welded pipe, the I-beam should be standing rather than lying down.Compared with manual binding, the concrete can be poured, eliminating the links of reinforcement on-site cutting, placing one by one and binding. It can save % - % of working hours, greatly accelerate the construction progress and shorten the construction cycle. The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Honest service,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.GB No. I-beam is in height, in leg width and in waist thickness.At the same height, 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.

The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, not very little aluminum alloy, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust.Latest quotation,The finished product has smooth surface, low friction coefficient flatness error + / - mm / m length, wear resistance and maximum temperature of ℃ Seamless pipe is resistant to corrosion, acid, alkali, salt and atmospheric environment, high temperature, does not need regular maintenance, and the effective life is more than years;As shown in the name, I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination, generally :, which makes the outer flange thin and the inner flange thick. Therefore the section characteristics of I-beam in the two main planes are very different, and it is difficult to give full play to the strength characteristics in application. Although the thickened I-beam has also appeared in the I-beam market, the structure of the I-beam has determined its torsional performance.Periko,The key purpose of grinding and polishing alloy pipe is to moisten the surface, and the relevant limit accuracy or appearance change is not easy to change. 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.Key technical characteristics of alloy pipe
