Square tube structural steel A. mechanical steel: (a) quenched and tempered structural steel; (b) Surface hardening structural steel: including carburized steel ammoniated steel and surface quenching steel; (c) Easy to cut structural steel; (d) Steel for cold plastic forming: including steel for cold stamping and steel for cold heading.Cleaning solvent and emulsion can clean the surface of square tube to remove oil, grease, dust, agent and similar organic matter, scale, welding, etc. on the surface of square tube, so it is only used as an auxiliary means in production.Bihachi,In case of doubt about the strength of solid qb square tube, it can be based on tb & mdash; the compressive strength of qb square tube on the surface of the structure is indirectly measured by the post loading method. The measurement should be carried out at the age of about days, and the measured average strength is required to be not lower than the design value or the specified value. When the requirements are not met the core drilling sampling method can be used for verification.Fatigue strength, plasticity and hardness discussed above are indicators of the mechanical properties of metals under static load. In fact, many machine parts work under cyclic load, under which fatigue will occur.Zakho,B. spring steel C. bearing steel tool steel: A. carbon tool steel; b. Alloy tool steel; c. High speed tool steel.A. square tube structural steel: (a) high quality carbon structural steel; (b) Alloy structural steel; (c) Spring steel; (d) Easy cutting steel; (e) Bearing steel; (f) High quality structural steel for specific purposes.For structure: as pile driving pipe and bridge; pipe for wharf, road and building structure, marine pile driving pipe, etc.

: it refers to the processing of square tube, 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.Square pipe the steel pipe whose ratio of outer diameter to wall thickness is less than is called square pipe. At present, the square tubes produced by qb square tube factory are mainly used in tap water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation and urban construction. For transportation: water supply and drainage. For gas transmission: gas, steam and liquefied petroleum gas. For structure: for punchingIn recent years, large-diameter seamless square tube plays a good role in economic development. Because there are many types of large-diameter seamless square tubes, the continuous casting process of large-diameter seamless square tubes is also different. What are the specific steps of the continuous casting process of large-diameter seamless square tube? As the name suggests, which are unpacked, leveled, crimped and welded to form round tubes, Then the round pipe is rolled into a square pipe, and then cut into the required length. Generally, square tubes per package are mostly in large specifications in terms of spot, and . - ~~ - square tubes are divided into structural square tubes, decorative square tubes, building square tubes, mechanical square tubes, etc. according to their uses.Economic management,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. special shaped square pipe is the general name of square pipes with other cross-section shapes except circular pipe. According to the different cross-section shape and size of steel pipe, it can be divided into special-shaped square pipe with equal wall thickness (code D), special-shaped square pipe with unequal wall thickness (code BD) and special-shaped seamless steel pipe with variable diameter (code D) These special-shaped large-diameter qb square tubes are widely used in various structural parts, tools and mechanical parts. Compared with circular tubes, special-shaped tubes generally have large moment of inertia and section modulus, which can greatly reduce the structural weight and save steel. Square tubes are an indispensable part of construction workThe disadvantage of solid bending is that it has tensile thinning effect. The actual bending will produce tension at the bending point, and the tensile effect will shorten the longitudinal length of the bending line; The metal at the real bend will become thinner due to stretching.

For gas transmission: gas, steam and liquefied petroleum gas.Recommendation and consultation,Welding seamless welding seamless is to make welded elbows. After grinding and pickling, sand blasting, there is no sign of welding on the surface. Even using advanced flaw detection equipment, it can not be seen that they are welded elbows.Square pipes are mainly used in engineering buildings, glass curtain walls, door and window decoration, steel structures, guardrails, automobiles, household appliances, shipbuilding,BihachiGalvanized square pipe production line, containers, electric power, agricultural construction, agricultural greenhouses, bicycle frames, motorcycle frames, shelves fitness equipment, leisure and tourism, steel furniture, various specifications of oil casing, oil pipes and pipeline pipes, water, gas, sewage, air Heating and other fluid transportation, fire fighting and support, construction and other fields.Square tube production most square tube processing is square tube pressure processing, resulting in plastic deformation of the processed steel (billet, ingot, etc.). According to the square tube processing temperature, the square tube can be divided into cold processing and hot processing. The main processing of square tube includes: rolling: the gap (various shapes) between the square tube metal blank and the rotating roll , because of the compression of the roll, the material section is reduced and the length is increased. This is a common production method for producing square tubes. It is mainly used to produce square tube profiles plates and tubes. It is divided into cold rolling and hot rolling.Bihachi,B. low alloy structural steel C. ordinary structural steel and high-quality steel for specific purposes (including high-quality steel)Due to the increase of square tube production, there are more and more fake and shoddy square tubes in the market. How to distinguish the fake and shoddy square tubes? Let me teach you some points to distinguish the fake and shoddy square tubes.Square tube production most square tube processing is square tube pressure processing, resulting in plastic deformation of the processed steel (billet, ingot, the square tube can be divided into cold processing and hot processing. The main processing of square tube includes: rolling: the gap (various shapes) between the square tube metal blank and the rotating roll ,BihachiGalvanized Q235 square pipe, because of the compression of the roll, the material section is reduced and the length is increased. This is a common production method for producing square tubes. It is mainly used to produce square tube profiles, plates and tubes. It is divided into cold rolling and hot rolling.
