Heating surface pipes, economizers, superheaters, reheaters, pipes for petrochemical industry, etc. for high-pressure boilers (working pressure is generally above MPa and working temperature is between ℃ ~ ℃)The specification of pass design I-beam is expressed in cm of waist width. For example, 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.Farnipo, Pipe installation:Application characteristics of I-beamLarge,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.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.Requirements of alloy tubes for low and medium pressure boilers

Introduction to product knowledge of alloy pipe: For the surface mesh of the height difference plate, when the height difference is ≤ mm, the surface mesh can be bent and installed; when the height difference plate is more than mm, the surface mesh should be disconnected at the place with height difference and put into the beam respectively. The anchorage length of the reinforcement is required for the reinforcement to extend into the beam.Alloy pipe is a very important way and type of seamless steel pipe. Its use is relatively common. It is widely used in various engineering projects, house construction and building decoration. Its fracture will always be found in the production, manufacturing and key marketing of alloy pipe, That is, many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons.Where can I find it?,→ compared with general section steel, it has the advantages of low cost,Farnipo15CrMo high pressure alloy pipe, high precision and small residual stress. It does not need expensive welding materials and weld detection, and saves about % of the manufacturing cost of steel structure. Peak crack→ wide flange and large lateral stiffness. Strong bending resistance.

Requirements of alloy tubes for low and medium pressure boilersFree consultation,FarnipoHow much is a ton of welded pipe, Frame line crack It has iron zinc alloy layer and compact combination, which shows unique corrosion resistance in marine salt spray atmosphere and industrial atmosphere;Aiming at the connective tissue and texture produced in stainless steel plate Position and other crystal defects are generally removed by heat treatment processes such as quenching or quenching. The effect of quenching is to optimize the crystal, reduce strength improve plastic deformation, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe, quenching machinery and equipment cannot be lacked. Therefore,FarnipoHow much is a DN50 galvanized pipe, the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness reduce the product cost and reduce the quenching process, it will eventually lead to bad harm to the product quality.Farnipo,What should we pay attention to in the production of alloy pipe→ wide flange and large lateral stiffness. Strong bending resistance.I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.
