also known as universal beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.Compastra asuyaNext, 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, gas nitriding is widely used in the production of alloy steel pipe.Oyem,The core of C-section steel is the structural system of braced frame. More than half of such senior managers in China are the former. Unfavorable to earthquake resistance. Hydraulic power, and the power is large, generally about KW, which is similar to the plate shearing and bending machine. The general control process is complex, and PLC control is mostly used.Plan scheme : high carbon steel with carbon content exceeding .% and alloy pipe with chromium content not less than %Generally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.

→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.In addition to these, the advantages of galvanized pipe are also reflected in some other aspects. For example, its reliability is also very good. Because the combination of zinc coating and steel is good news for metallurgy, it has become a part of galvanized steel pipe on the steel surface. In this way, the durability of its coating is more reliable. And when the zinc coating forms a special metallurgical structure, this structure can withstand mechanical damage during transportation and use. When in use,Compastra asuyaHow much is 219 welded pipe per ton, it also has the advantages of multiple protection. Because every part of the product can be plated with zinc, even in depressions, sharp corners and hidden places can be protected in many ways. It is very convenient during construction. It really saves time and effort. It is because of so many advantages that the utilization rate of this product is very high. And it can avoid the time required for painting on the site after installation. If you want to purchase on your occasion, remember to go to the manufacturer, so that the price will be more favorable.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.Scheme customization,Generally,Compastra asuyaAlloy pipe, the process of pickling and passivation will be carried out for alloy pipes, but the alloy pipes after pickling and passivation are very easy to rust. Therefore, the way to find a solution to wiredrawing corrosion is 'grinding and polishing'. Due to grinding and polishing, bearing performance and service life. This paper systematically introduces the development of high quality cold drawn bearing steel pipe and its application in bearing. Precision cold rolling of small and medium-sized bearing sleeves with bearing steel pipes can greatly improve material utilization, bearing performance and service life. This paper systematically introduces the service life of high quality cold drawn bearings.a. In the forming process, the thick steel plate has uniform deformation, small internal stress and no scratch on the surface. The alloy pipe produced and processed has higher coordination ability in the scope of size,Compastra asuya09CrCuSb alloy pipe, specification and model of diameter and wall thickness, especially in the production and manufacturing of steel structure design grade thick wall pipe, especially medium diameter small thick wall pipe, which has incomparable advantages of other processing technologies, and can meet a large number of customer regulations on the specification and model of alloy pipe.

The finished product has smooth surface, low friction coefficient, flatness error + / - mm / m length, wear resistance and maximum temperature of ℃Product line, Frame line crack Steel pipe with complex section -- unequal hexagonal steel pipe five petal quincunx steel pipe, double convex steel pipe, double concave steel pipe, melon seed steel pipe, conical steel pipe, corrugated steel pipe, watch case steel pipe and others.Introduction to product knowledge of alloy pipe:Compastra asuya,C-section steel has uniform zinc layer smooth surface, strong adhesion, no zinc scar, no zinc leakage and high dimensional accuracy. All surfaces are wrapped by zinc layer, and the zinc content on the surface is usually -g /? It has long service life, corrosion resistance and durability. It is a kind of stronger protection.Application scope of alloy pipeThe side length of I-beam is small and the height is large, so it can only bear the force in one direction.
