→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.The side length of I-beam is small and the height is large, so it can only bear the force in one direction.Indibuka,How are seamless tubes made?At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.Los-Reyes-la-PazXhy- series high hardness alloy I-beam; Undertake drawings and process wear-resistant pipes（ Φ ≥mm）； Undertake the processing and production of vulnerable parts of cement machinery; Welding technology consultation and service; The wear-resistant layer of alloy wear-resistant plate of high chromium heap welding flux cored wire series is mainly high chromium, as well as manganese, molybdenum, niobium, francium and other components. The alloy carbide formed has strong stability at high temperature.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 ℃ ~ ℃)Key technical characteristics of alloy pipe

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,IndibukaHow much is a 25 yuan steel bar, we have produced galvanized pipe products for many years. Welcome friends who need to buy.When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.Scheme customization,Application scope of alloy pipeUnder 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, and the greater the final residual stress. On the other hand, due to the change of microstructure during heat treatment, i.e. the transformation from austenite to martensite,Indibuka15CrMoG seamless pipe factory, the increase of specific volume will be accompanied by the expansion of workpiece volume, and each part of workpiece will undergo phase transformation successively, resulting in inconsistent volume growth and structural stress. The final result of the change of tissue stress is the tensile stress on the surface and the compressive stress in the center, 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. Remove defective pipes within the allowable length.

The shape of I-beam is similar to that of H-beam. What is the difference between them?Range,Alloy pipes can be used for heating (cooling) projects.There are several ways to clean galvanized pipesWhat are the requirements for alloy pipe construction accessoriesIndibuka, light I-beam has narrower legs,IndibukaHow much is 1 meter of 50 welded pipe, thinner waist and lighter weight than ordinary I-beam. No. - is large I-beam and No. - is medium I-beam. Imported I-beam shall be marked with actual specifications, dimensions and relevant standards.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, meet the requirements of thermal insulation and cold protection, reduce heating equipment, 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.I-beam, also known as steel 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.
