Shandong weinaishi Steel Pipe

Shandong weinaishi Steel Pipe Co., Ltd. has become a qualified supplier of domestic boiler, electric power, petrochemical and energy industries. Haimen steel beam I-beam spot supply 4. The flange of H-beam is uniform. Different from the common I-section, the flange of H-beam is not widened, and the inner and surface surfaces are usually parallel, so that it can be easily connected with other components by high-strength bolts. Its size composition series is reasonable and the model is complete, which is convenient for design and selection. 6. From the perspective of acceptance force, H-beam is vertical down force, while I-beam is the force in the direction of acceptance degree, which is why designers design I-beam and H-beam. Do you know the main uses of H-beam? Xingaoweiye will explain to you that H-beam, as a new type of economic building material, has the advantages of economic and reasonable section shape and good mechanical properties; when rolling, all points on the cross-section extend evenly and the internal stress is small; compared with ordinary I-beam, it has the advantages of large section modulus, light weight and metal saving. It can reduce the building structure by 30-40%; and because the inside of H-shaped steel leg is parallel and the leg end is right angle, it can be disassembled and assembled into components. It can greatly save welding and riveting workload. Therefore, H-beam is often used in large-scale buildings with large bearing capacity and good cross-section stability, such as workshops, high-rise buildings, bridges, ships, lifting and transportation machinery, equipment foundation, support, foundation pile, etc. The flange of H-beam is of equal thickness, with rolling section and 3 piecesBecause of the poor production technology, the inner edge of the flange has a slope of 1:10. The rolling of H-beam is different from that of the general I-beam. Only one set of roller is used for H-beam rolling. In view of its wide flange and no slope (or too small slope), a group of vertical rollers should be added and rolled at the same time. Therefore, the rolling process and setting are more complicated than those of the general rolling mill, and the steel price is higher Qianke's large rolling H-beam is 800mm in height, which is beyond the welding combination section. the company's business: q235bh section steel, non-national standard H-beam, angle steel, galvanized angle steel, Q235B angle steel, equal angle steel, unequal angle steel, bracket angle steel, channel steel, hot-rolled channel steel, DN80 galvanized pipe, DN 100 galvanized pipe, small diameter galvanized pipe, large diameter galvanized pipe National standard galvanized pipe, square pipe, galvanized square pipe, etc. Products are widely used in: petroleum, chemical, natural gas transmission, piling, urban water supply, heating, gas supply and other projects. It is specialized in providing high-quality seamless steel pipe, boiler pipe and q345gnhl pipe for power plant, chemical plant, boiler plant, oil refinery, machinery plant, environmental protection engineering, steel structure plant, thermal power plant, petrochemical, oil field, etc. Standard for seamless pipe: seamless pipe for general structure: (GB / t8162-2008) seamless pipe for conveying fluid: (GB / t8163-2008) seamless pipe for low and medium pressure boiler: (GB / t3087-1999) seamless pipe for high pressure boiler: (GB / t5310-1995) seamless pipe for chemical fertilizer: (GB / t6479-200)0) seamless pipe for petroleum cracking: (GB / t9948-1988). The company always adheres to the business policy of "quality first, scientific management, excellence" and the business philosophy of "honest management, flexible innovation", establishes and improves the quality assurance system, and strives to achieve "the user is at ease, the user is satisfied with me". Q235B I-beam manufacturers H-beam for the future development of the construction industry, I come to the conclusion that in the future, it can not do without high-frequency welding H-beam. As a good steel with high quality, high value and low cost, I think it is the steel product that every building material market needs. In addition to the above characteristics, our high-frequency welded H-beam has many advantages, such as small cross-section error, which makes structural assembly more convenient and convenient. This kind of advantage has indeed moistened many colors for high frequency welding H-beam. The more advantages of high frequency welding H-beam are not mentioned. Need to use steel to explore with heart. Various processing methods of 304 stainless steel pipe are briefly introduced. According to different applications, 304 stainless steel pipe has different processing methods, including cold drawing processing, welding processing, stamping processing, etc. The following specific introduction of 304 stainless steel pipe processing methods: 1, cold drawing deep processing: easy to produce friction heat, so the use of high pressure, heat resistance 304 stainless steel pipe at the same time, after the end of molding processing should remove the oil attached to the surface. 2. 304 stainless steel pipe processing and welding: before welding, rust, oil, water and paint harmful to welding shall be completely removed,Select suitable electrode for steel grade. The time interval of spot welding is shorter than that of carbon steel. 304 stainless steel pipe brush should be used to remove welding slag. After welding, the surface shall be ground or cleaned to prevent local corrosion or strength reduction. prefabricated steel structure If H-beam is stacked in a covered warehouse, please put the H-beam directly in the air, and place a wooden mat under it to avoid direct contact with the air. Attention should be paid to deformation and corrosion of H-beam when stacking. To prevent this problem, you can choose to lay some 5-6 layers of wood mats. The spacing should not cause excessive bending of the H-beam. Of course, when you stack, you have to reserve a way to transport early. Different specifications of H-section steel should be marked near the left. The specification, steel grade, quantity and data of H-beam shall be clearly indicated, and the acceptance certificate number shall be provided. You can also choose to use different colors of paint to identify them. There is no use stopping regular checks on logos.
