Impact toughness the load acting on the machine part at a great speed by QB is called impact load, and the ability of metal under impact load is called impact toughness.The appearance of fake and inferior square tubes often has pitting. Pockmarked surface is an irregular uneven defect on the surface of square lead pipe due to serious wear of rolling groove. Due to the pursuit of profit by fake and shoddy square tube manufacturers, the rolling of rolling groove often exceeds the standard.Cambridge,The general delivery length of square pipe is mm-mm, mostly mm and mm. The square tube is allowed to deliver short and non fixed length products not less than mm, or in the form of interface tube, but the Demander shall cut off the interface tube when using it. The allowable deviation of the wall thickness of square pipe shall not exceed plus or minus % of the nominal wall thickness when the wall thickness is not greater than mm, plus or minus % of the wall thickness when the wall thickness is greater than mm, except for the wall thickness of corners and weld areas. The weight of short gauge and non fixed gauge products shall not exceed % of the total delivery. For square tubes with a theoretical weight greater than kgm, we can correctly select the appropriate application field, In this way, the use efficiency of square tube can be improved. Next, we will mainly explain the characteristics of pipe cooling technology below. What are the main characteristics of square tubes? Square tube parts have accurate dimensions and smooth surfaces: the dimensional accuracy of cold parts developed at present can reach grade ~ . If ideal ones are adopted, their accuracy is second only to that of fine polished surfaces. Therefore, and a small amount only need finishing (grinding).: it refers to the processing of square tube, which places metal in a closed Jane and applies pressure at the end to extrude the metal from the specified die hole to obtain finished products with the same shape and size. It is mostly used to produce non-ferrous metal materials. Square tube ferrous metal, steel and non-ferrous metal. Before introducing the classification of steel, briefly introduce the basic concepts of ferrous metal, square tube steel and non-ferrous metal.Novi Pazar,The load of impact toughness acting on the parts at a great speed is called impact load. It is specialized in products and renewable resources. Its business includes: square tube, square tube, seamless square tube, galvanized square tube and galvanized tube. The ability of metal under impact load is called impact toughness.QB square tube is a product appeared in recent years,CambridgeHot dip galvanized steel pipe, which mainly has strict tolerance and roughness for the dimensions of inner hole and outer wall. Production process classification of large-diameter qb square tube large-diameter qb square tube is divided into hot-rolled seamless square tube,CambridgeSpecification and model of galvanized pipe, cold drawn seamless square tube, seamless square tube and qb square tube according to production process. Among them, qb square tube is divided into: (a) by process & mdash& mdash; Arc welded square pipe, resistance welded square pipe (high frequency and low frequency), # steel, # steel, etc; Low alloy steels are divided into q Mn, Q, St-, etc.Square tube is an essential material for the construction and Realization of industrialization. It is widely used and has a wide variety. According to different section shapes, square tube is generally divided into sections, plates, pipes and metal products. In order to facilitate the production, ordering and supply of square tube and do a good job in operation and management, it is also divided into heavy rail, light rail, large section steel, medium section steel, small section steel and square tube cold bending Section steel, high-quality section steel, wire rod, medium and thick steel plate, sheet steel, electrical silicon steel sheet, strip steel, seamless steel pipe, square pipe, welded steel pipe metal products, etc.

Stage ( & mdash; )Functional index analysis of square tube - angular plasticity refers to the power of plastic deformation (permanent deformation) without destruction of square tube data under load.Ferrous metals refer to iron and iron alloys. Such as steel, pig iron ferroalloy, cast iron, etc. Steel and pig iron are alloys based on iron square tube and carbon as the main added element, collectively referred to as iron carbon alloy.investment,When the vehicle is replaced with seamless square tube blank, the material is too soft to affect the requirements so as to ensure the quality of parts and avoid wrinkles.B. low alloy structural steel C. ordinary structural steel and high-quality steel for specific purposes (including high-quality steel)High pressure oil pipe for diesel engine (gb-) is a cold drawn square pipe for high pressure pipe of diesel engine system.

Comprehensive classification ordinary steel A. carbon structural steel: (a) Q (b) Q (b); (c) Q( C); (d) Q( B); (e) Q.Industry management, qb square tubeQb square tube, QB square tube, QB square tube and hot-rolled right angle square tube are of good quality and excellent quality. We have become a supplier of many enterprises. Qb square tube and I-beam are two products with different shapes. Under the condition of the same material, the bearing capacity of steel is the same, but their uses are very different. The shape is different. Qb square tube is a cuboid, and I-beam is in I-shape. The purpose is different. I-beam can be used as span and support. Square pipe is a little worse than span. It is no problem to do support. However, the specific selection of steel depends on the requirements of the project. Square tube practical application square tube for structure (gbt-) is a square tube for general structure and mechanical structure.The formed square tubes shall be tested to ensure that each piece is qualified. The qualified square tubes will be stored. Various problems will occur in the long-term storage. If there are problems, we need to deal with them in time. What are the reasons for the rusting and corrosion of square tubes? Let's introduce them to you next.Generally, chemical and electrolytic pickling are used for pickling treatment. Only chemical pickling is used for pipelines, which can remove oxide scale, rectangular tubes, seamless square tubes, galvanized square tubes and galvanized tubes are safe, environmentally friendly and economical! The products are exported to foreign countries and are deeply trusted. Sometimes they can be used as reprocessing after sand blasting and rust removal. Although chemical cleaning can make the surface reach a certain cleanliness and roughness, its anchor lines are shallow and easy to pollute the environment.Cambridge,Classification of square pipe material square pipe is divided into ordinary carbon steel square pipe and low alloy square pipe according to material. Ordinary carbon steel is divided into Q Q q SS, # steel # steel, etc; Low alloy steels are divided into q Mn, Q, St-, etc.The surface of galvanized square pipe treated by sand blasting, shot blasting or pickling process is relatively clean, and the oxide scale and rust are removed,Cambridge75 galvanized square pipe, which improves the adhesion of the coating. When the installation site unconditionally adopts sand blasting and shot blasting, manual and mechanical derusting can be adopted, but the derusting quality level must be reached.Steel for construction and engineering according to the classification of use without phase transformation or partial phase transformation of square tube: A. ordinary carbon structural steel; b. Low alloy structural steel; c. Steel reinforcement.
