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.When it is used for ground heating and hot spring transportation, it can meet the requirements of refrigeration and achieve the practical effect of less damage. It is applicable to water conservancy engineering, mining and other industries to meet the provisions of cold, cold and corrosion prevention. In addition the chemical raw material transmission pipeline has a wide indoor space.Lavender,The pollution of the joint causes the welding cracking. The composite pipe welding is an accurate work. If it is not done well, it will not only waste resources, but also lead to work efficiency, rework and restart, and waste financial resources.→ 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.Gabon,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.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, specification and model of diameter and wall thickness, 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.Plan scheme : for high carbon steel with carbon content of more than .% and high chromium alloy pipe with chromium content of no less than %, the interval is min.

The working principle of flat steel finishing machine in I-beam production process is to pre level and finally level the cold flat steel with two groups of leveling wheel sets staggered up and down in the thickness direction; A pair of finishing wheels arranged relatively are used to extrude the width direction, so that the width is compressed to achieve the expected parameters, and the compression amount is adjustable; Straighten the width with staggered straightening wheels. Ditch cover plate (ditch cover plate) is widely used in municipal roads, garden facilities, residential quarters, schools, stadium pipes and other places.Introduction to product knowledge of alloy pipe:Recommendation and consultation,Lavender15CrMo alloy pipe factory,The shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm.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,Lavender25 welded pipe is more than one meter, 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.Due to the unique performance of I-beam,Quality assuranceI-beam is divided into ordinary I-beam and light I-beam. The specification of hot rolled ordinary I-beam is -#. The specification of hot-rolled flexible I-beam supplied through agreement between the supplier and the buyer is -#. I-beam is mainly used in building structure, vehicle manufacturing, other industrial structures and fixed panels and cabinets. I-beam is often used together with I-beam. . the straight length of the hook of the surface mesh reinforcement at the grid support shall not be less than mm, I-beam has the advantages of strong bending resistance,Lavender12 price quotation of I-beam, 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.Lavender,It can withstand continuous moderate impact and can provide composite plates of various thicknessesAlloy pipes can be used for heating (cooling) projects.When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.
