无缝钢管是一种具有中空截面、周边没有接缝的长条钢材。无缝钢管是用钢锭或实心管坯经穿孔制成毛管,钢管混凝土构造用钢管

Seamless steel pipe is a kind of long steel with hollow section and no joint around it. Seamless steel tube is made of steel ingot or solid billet through perforation, and steel tube for concrete filled steel tube construction

1.钢管混凝土构造依照截面方式的不同,可分为矩形、圆和多边形钢筋混凝土构造,其中矩形钢管混凝土构造应用较广。

1. Concrete-filled steel tubular structures can be divided into rectangular, circular and polygonal reinforced concrete structures according to the different section modes. Rectangular concrete-filled steel tubular structures are widely used.

2.钢管混凝土构造用钢管可采用直缝焊接收、螺旋形缝焊接收和无缝钢管。

2. Steel tube for concrete filled steel tube construction can be welded by straight seam, spiral seam and seamless steel tube.

钢筋混凝土常用热轧钢筋分类

Classification of Hot Rolled Reinforcement Bars for Reinforced Concrete

1.光圆:HPB300;代号

1. Optical circle: HPB300; code name

2.带肋:HRB335、HRBF335、HRB400、HRBF400、HRB500、HRBF500然后经热轧、冷轧或冷拨制成。无缝钢管在我国钢管业中具有重要的位置。无缝钢管在输水、气管道有普遍应用,此外也用于石油、化工、锅炉、汽车、拖拉机、航空等范畴。

2. Ribbed: HRB335, HRBF335, HRB400, HRBF400, HRB500, HRBF500 and then made by hot rolling, cold rolling or cold dialing. Seamless steel tube plays an important role in China's steel pipe industry. Seamless steel pipes are widely used in water and gas pipelines, as well as in petroleum, chemical industry, boilers, automobiles, tractors, aviation and other fields.

无缝钢管分类

Classification of Seamless Steel Pipe

中国无缝管网据新闻报道:依据消费办法不同分为热轧(挤压、扩)无缝管、冷拔(扎)无缝管等。

According to news reports, China seamless pipeline network can be divided into hot-rolled (extruded, expanded) seamless pipe and cold-drawn (tied) seamless pipe according to different consumption methods.

依据材质可分为:普通和优质碳素构造钢(Q215-A~Q275-A和10~50号钢)、低合金钢(09MnV、16Mn等)、合金钢、不锈耐酸钢等。

According to the material, it can be divided into ordinary and high quality carbon structural steel (Q215-A~Q275-A and 10-50 steel), low alloy steel (09MnV, 16Mn, etc.), alloy steel, stainless acid-resistant steel, etc.

按用处可分为:普通用处的(用于输水、气管道和构造件、机械零件)和专用的(用于锅炉、地质勘探、轴承、耐酸等)两类。

According to its use, it can be divided into two categories: general use (for water conveyance, gas pipeline and structural parts, mechanical parts) and special use (for boilers, geological exploration, bearings, acid resistance, etc.).

无缝钢管规格尺寸

Specification and Dimension of Seamless Steel Pipe

公称直径采用符号DN表示,无缝钢管的管子的外径用字母D来表示,其后附加外直径的尺寸和壁厚,例如外径为108的无缝钢管,壁厚为5MM,用D108*5表示

The nominal diameter is denoted by the symbol DN, and the outer diameter of seamless steel pipe is denoted by the letter D, followed by the size and wall thickness of the additional outer diameter, such as seamless steel pipe with an outer diameter of 108 and a wall thickness of 5MM, denoted by D108*5.

无缝钢管重量计算的公式

Formula for calculating the weight of seamless steel tube

每米重量的计算公式为: W(kg/m)=0.02466*壁厚*(外径-壁厚),其常用规格理论重量见下表:

The formula for calculating the weight per meter is W(kg/m)=0.02466*wall thickness*(outer diameter-wall thickness). The theoretical weight of the commonly used specifications is shown in the table below.

无缝钢管用处

Use of Seamless Steel Pipe

普遍用于制造构造件和机械零件,如石油钻杆、汽车传动轴、自行车架以及建筑施工中用的钢脚手架等。钢管还是各种常规武器不可短少的资料,枪管、炮筒等都要钢管来制造。

It is widely used in the manufacture of structural and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction. Steel pipe is also indispensable information for all kinds of conventional weapons. Steel pipe is used to manufacture barrels, barrels, etc.

相信看了本文的济南镀锌管http://www.jnxxjm.com 介绍后,对这方面也会有自己的一番认识,以后针对的等问题也能很好的解决。

I believe that after reading the introduction of Jinan galvanized pipe http://www.jnxxjm.com in this paper, I will have my own understanding of this aspect, and other problems can be solved well in the future.
