蒸呢机,是方形管材的一种称呼,也就是边长相等的的钢管。在抗弯、抗扭强度相同时,重量较轻,所以广泛用于制造机械零件和工程结构。蒸呢机广泛用于建筑,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 pipe is a form of address for square pipe, that is, steel pipe with equal side length. When the bending and torsion strength are the same, the weight is lighter, so it is widely used in manufacturing mechanical parts and engineering structures. Square pipes are widely used in construction, machinery manufacturing, steel construction and other projects, such as shipbuilding, solar power bracket, steel structure engineering, power engineering, power plant, agricultural and chemical machinery, glass curtain wall, automobile chassis, airport, boiler construction, high-speed rail, building, pressure vessel, oil storage tank, bridge, power plant equipment, lifting and transportation machinery and other high-load projects. Welded structural parts are also widely used.
蒸呢机规格尺寸
Square Pipe Specification and Dimension
蒸呢机的规格标示方法:主要是以边宽*边宽*管壁厚度表示。如16×16×0.4~1.5则表示边宽为16mm,管壁厚度为0.4-1.5mm。
Specification marking method of square pipe: mainly expressed by edge width * edge width * wall thickness. If 16 x 16 x 0.4-1.5, the width of the edge is 16 mm and the thickness of the tube wall is 0.4-1.5 mm.

蒸呢机重量计算
Square tube weight calculation
蒸呢机重量计算公式:重量={(长-壁厚)×2÷1000+(宽-壁厚)×2÷1000}×7.85×壁厚×长度。常用规格理论重量见下表。
The formulas for calculating square tube weight are as follows: weight={(length-wall thickness)*2_1000+(width-wall thickness)*2_1000}*7.85_wall thickness*length. The theoretical weight of commonly used specifications is shown in the table below.
备注:以上单位为kg/m,其中壁厚和边长的单位为毫米,即mm。
Note: The above units are kg/m, and the units of wall thickness and side length are mm, that is mm.
