济南方管: 方管的定义和用途

发布时间:2024-09-21 来源:http://www.jnhxtcg.com/

  方管,顾名思义就是方形的钢管,一般是由带钢或者是钢板卷制焊接而成的方管。大口径的方管有直缝方管和无缝方管。直缝的方管一般是由带钢或者是钢板焊接卷制的。无缝的方矩管是由无缝管做母材,通过改拔或者是冷拔进行生产,也就是所谓的圆变方。

  Square tube, as the name suggests, is a square steel pipe, usually made of steel strip or steel plate rolled and welded into a square tube. Large caliber square tubes include straight seam square tubes and seamless square tubes. Straight seam square tubes are generally made of welded coils of strip steel or steel plates. Seamless square tube is made of seamless tube as the base material and produced by drawing or cold drawing, which is called circular to square.01

  生产工艺

  Production process

  方管是空心为方形的横截面轻质薄壁钢管,又称钢制冷弯曲型材。现在最常见的材质是Q235,其中Q235又分BCD等等级,有缝方管是以Q235热轧或冷轧带钢或卷材为基础,然后通过高频焊接成形,这种方式只适用于普通要求的方管,通常性能更好,密封性更强的方管,我们通常采用无缝圆管,冷轧形成,相对于冷轧还有热轧方管, 热轧超厚壁方管以壁厚增厚而闻名,其硬度值根据硬度检测程度进行测量。

  Square tube is a lightweight thin-walled steel pipe with a hollow square cross-section, also known as a steel refrigeration bending profile. The most common material now is Q235, which is divided into BCD and other grades. Welded square tubes are based on Q235 hot-rolled or cold-rolled steel strips or coils, and then formed by high-frequency welding. This method is only suitable for ordinary square tubes with better performance and stronger sealing. We usually use seamless round tubes, cold-rolled to form. Compared with cold-rolled and hot-rolled square tubes, hot-rolled ultra thick walled square tubes are famous for increasing wall thickness, and their hardness values are measured according to the degree of hardness testing.

  02应 用

  02 Application

  钢结构

  steel structure

  有缝方管通常可以通过钢板焊接而成,通常用于钢结构等,可塑性是指金属材料在负载的情况下,能够减慢对金属形态产生可塑性变形(永久变形)而不破坏的能力。

  Welded square tubes are usually made by welding steel plates and are commonly used in steel structures. Plasticity refers to the ability of metal materials to slow down the plastic deformation (permanent deformation) of the metal form under load without damage.

  机械制造

  Mechanical manufacturing

  由于其结构稳定、刚度大、重量轻等特点,常用于制造机械设备等框架、支架、轴承座等部件,它可以提高良好的支撑和保护,使机械设备能够正常运转并承受一定的荷载。

  Due to its stable structure, high stiffness, and light weight, it is commonly used in the manufacturing of frames, brackets, bearing seats, and other components of mechanical equipment. It can improve good support and protection, enabling mechanical equipment to operate normally and withstand certain loads.

  桥梁建设

  Bridge construction

  桥梁是连接两个地点的重要交通设施,它在桥梁的建设中发挥重要作用,常用于制作桥梁的梁,墩柱和桥梁面板等部件,它具有较高的抗弯强度和抗压能力,能够有效的承受桥梁的自重和荷载,此外,还具有良好的防腐性质,能够抵御恶劣的环境条件,延长桥梁使用寿命。

  A bridge is an important transportation facility that connects two locations and plays a crucial role in bridge construction. It is commonly used to make components such as beams, piers, columns, and bridge panels. It has high flexural strength and compressive capacity, and can effectively withstand the weight and load of the bridge. In addition, it has good anti-corrosion properties, which can withstand harsh environmental conditions and extend the service life of the bridge.

  公路护栏

  highway guardrail

  公路护栏和栏杆是保护交通安全的重要设施,它在其中扮演者重要角色,用于制造公路护栏和栏杆的立柱和横梁,它具有较高的强度和刚度,能够有效的抵挡车辆的冲击和碰撞,保护行人和车辆的安全,此外,还具有良较好的可塑性和耐腐蚀性,能够适应不同的气候条件和环境要求。

  Highway guardrails and railings are important facilities for protecting traffic safety, playing an important role in them. They are used to manufacture the columns and beams of highway guardrails and railings, which have high strength and rigidity, can effectively resist the impact and collision of vehicles, protect the safety of pedestrians and vehicles. In addition, they also have good plasticity and corrosion resistance, and can adapt to different climatic conditions and environmental requirements.

  方管广泛用于建筑、机械制造、钢铁建设等项目,在造船、太阳能发电支架,钢结构工程、电力工程、电厂、农业和化学机械、玻璃幕墙、汽车底盘、机场、锅炉建造、高速路栏杆、房屋建筑、压力容器、石油储罐、桥梁、电站设备、起重运输机械及其他较高载荷的焊接结构件也有大量使用。

  Square tubes are widely used in construction, machinery manufacturing, steel construction and other projects. They are also widely used in shipbuilding, solar power generation brackets, steel structure engineering, power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automotive chassis, airports, boiler construction, highway railings, building construction, pressure vessels, oil storage tanks, bridges, power plant equipment, lifting and transportation machinery, and other welded structural components with high loads.
