NaosaHow many kilograms per meter of 100mm welded pipe,

The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.I-beam has wide flange, thin web, many specifications and flexible use. It can save metal by % ~ % when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge end is at right angles, it is easy to assemble and combine into various components, which can save about % of the welding and riveting workload, greatly accelerate the construction speed of the project and shorten the construction period.Naosa,During the heating and cooling process of structural welded pipe workpiece, due to the inconsistent cooling speed and time of surface layer and core layer, the temperature difference will be formed, resulting in uneven volume expansion and contraction, resulting in stress, namely thermal stress. Under the action of thermal stress, the starting temperature of the surface layer is lower than that of the core layer, and the shrinkage is greater than that of the core layer, making the core layer stretch. At the end of cooling, the surface layer is compressed and the core is stretched because the cooling volume contraction of the core cannot be carried out freely. That is, under the action of thermal stress,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'.Some applications of I-beam: The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.

Advantages of using I-beam: reduce maintenance cost, reduce downtime, improve equipment operation rate, reduce wear, reduce equipment capacity and increase power consumptionIn order to strengthen the 'muscles and bones' of the bridge,NaosaReinforcement engineering turnover, the construction party specially paved two layers of reinforcement mesh before pouring cement.Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members.Installation works,Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materialsI-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.I-beam is widely used

Key technical characteristics of alloy pipe:Test conclusion,Because all parts of I-beam are arranged at right angles, simple construction, 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.Next, 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.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, so it is convenient to connect with other components with high-strength bolts. Its size composition is reasonable, series and models are complete, which is convenient for settingNaosa,Generally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.Alloy tube is widely used in our daily life, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape.
