Heating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃);I-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:Nicaragua,Since the s, with the rapid development trend of high-quality hot strip mill production and the development of electric welding and testing technology, the welding quality has been continuously improved, the types,NicaraguaHow much is the price of welded pipe per ton, specifications and models of welded steel pipes are increasing, and seamless pipes have been replaced in more and more industries. Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the way of welding. Classified by production mode: classified by processing technology - electric arc welded pipe, resistor welded pipe, (high frequency, low frequency) gas welded pipe, furnace welded pipe.H-section steel belongs to high-efficiency and economic cutting profile (other cold-formed thin-wall section steel,NicaraguaQ235B longitudinal welded pipe manufacturer, 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 settingSan-Jose-de-las-Lajas,I-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V, and the macro hardness is - HRCI-beam is widely used in buildings or other metal structures.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.

Alloy pipe is a spiral seam seamless steel pipe, often processed by warm extrusion and welded by automatic double wire double side arc welding process. The alloy pipe sends the hot-rolled strip steel to the welded pipe unit, and the hot-rolled strip steel is extruded through multiple passes. The hot-rolled strip steel is rolled slowly to produce annular pipe material with open mouth gap. Adjust the reduction amount of the extrusion roll to control the welding gap at ~ mm and make both sides of the weld flush.The smooth of steel pipe is mainly through tension reducing, which is a continuous rolling process of hollow base metal without center and tip. Under the condition of ensuring the capillary welding quality, the whole welded pipe is heated to more than ℃ by the welded pipe tension reduction process, and then rolled to finished pipes with various outer diameters and wall thicknesses by the tension reduction machine ( times in total). The fluid pipes produced by developed countries in the world have adopted the welded pipe smooth process in a large number of boiler pipes. With the development of society, Domestic hot welded pipe has gradually formed a situation to replace smooth pipe.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. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.Click to view,Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.The specification of pass design I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is. The types of I-beam include hot-rolled ordinary I-beam, 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.Key technical characteristics of alloy pipe:

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.discount,Classification introductionClassification by end shapeDefects of alloy pipe and solutions:Nicaragua,Because all parts of I-beam are arranged at right angles, I-beam has the advantages of strong bending resistance, 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, 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.Under the action of thermal stress, because the initial temperature of the surface layer is lower than that of the heart and the shrinkage is greater than that of the heart, the heart is pulled. At the end of cooling, because the final cooling volume shrinkage of the heart cannot be carried out freely, the surface layer is compressed and the heart is pulled. That is, under the action of thermal stress, the surface of the workpiece is finally compressed and the center is pulled. This phenomenon is affected by factors such as cooling rate, material composition and heat treatment process. The faster the cooling rate, the higher the carbon content and alloy composition, the greater the uneven plastic deformation caused by thermal stress during cooling, due to the change of microstructure during heat treatment, i.e. the transformation from austenite to martensite, the increase of specific volume will be accompanied by the expansion of workpiece volume, and each part of workpiece will undergo phase transformation successively,NicaraguaI-beam price of 18, which is just opposite to the thermal stress. The microstructure stress is related to the cooling rate shape and chemical composition of the workpiece in the martensitic transformation zone.→ compared with general section steel, it has the advantages of low cost, 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.
