C - section steel is reliable and stable in stress, can be accurately positioned, and is resistant to impact and vibration Moreover, it has good versatility and combination,Emulsified asphalt emulsion is also easy to use on the mobile slurry seal paver. It is necessary to mix on the machine and use additives for chemical control for maintenance.Heating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃);Charlottenlund,H-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange and the second is that the inner surface of the flange has no inclination, channel steel and angle steel. The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Dehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlement

I-beam whether ordinary or light, can only be directly used for bending members or lattice members on its Web because of its large and narrow section size and large moment of inertia difference between the two main axes on the section. It is not suitable for axial compression members and flexural members perpendicular to the web plane, so its application range is very limited. I-beams are widely used in buildings and other metal structures.Galvanized pipe features: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, Remove defective pipes within the allowable length.Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materialsApplication characteristics of I-beam:

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.Welcome calls ,Some applications of I-beam:The whole structure is composed of zinc and quaternary crystals, forming dense crystals and barrier layer on the plate, which effectively prevents the penetration of corrosion factors. From the point of view of the strong zinc corrosion resistance of the barrier layer, when the zinc sacrificial anode is at the forefront of protection, the scratches and scratches of some coatings and the insolubility of zinc oxide layer play a protective and blocking role.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,KiskunhalasHow much is DN200 galvanized pipe per meter, it is divided into wide, medium and narrow flange I-beams. The specifications of the first two are -, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange,Kiskunhalas254SMO alloy pipe, thin web and light weight. Wide flange I-beam, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.Kiskunhalas,Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption, not occupy the natural environment, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.Plan scheme : Martensitic chromium alloy pipe and chromium alloy pipe with Cr composition exceeding %, without high carbon steel and high chromium alloy pipe. The aqueous solution contains % sodium cyanide % ~ % (volume ratio), the solution temperature is ~ ℃ and the solution time is min.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, showing a 'high mountain' shape.
