无缝异型钢管厂生产规格外径是什么?

发布时间:2019-04-28人气:59

无缝异型钢管生产的时候都是有外径的,很多人都知道,但具体的不是很了解,那么接下来就让小编来给我们大家介绍一下无缝异型钢管的生产规格外径。由整块金属制成的,表面上没有接缝的钢管,称为无缝异型钢管。根据无缝异型钢管厂生产的方法,无缝管分热轧管、冷轧管、冷拔管、挤压管、顶管等。按照断面形状,无缝异型钢管分圆形和异形两种,异形管有方形、椭圆形、三角形、六角形、瓜子形、星形、 带翅管多种复杂形状。最大直径达650mm,最小直径为 0.3mm。根据用途不同, 有厚壁管和薄壁管。无缝异型钢管主要用做石油地质钻探管、石油化工用的裂化管、锅 炉管、轴承管以及汽车、拖拉机、航空用高精度结构钢管

Seamless special-shaped steel pipe production is always external diameter, many people know, but the specific is not very clear, then let Xiaobian to introduce to us all the production specifications of seamless special-shaped steel pipe diameter. Seamless special-shaped steel pipe is made of whole metal and has no seams on its surface. According to the production method of seamless special-shaped steel pipe factory, seamless pipe is divided into hot-rolled pipe, cold-rolled pipe, cold-drawn pipe, extruded pipe, pipe jacking and so on. According to the section shape, the seamless special-shaped steel pipe can be divided into two kinds: round and special-shaped. The special-shaped pipe has many complex shapes, such as square, ellipse, triangle, hexagonal, melon seed, star and finned pipe. The maximum diameter is 650 mm and the minimum diameter is 0.3 mm. According to different uses, there are thick-walled and thin-walled tubes. Seamless special-shaped steel pipes are mainly used for petroleum geological drilling pipes, cracking pipes for petrochemical industry, boiler pipes, bearing pipes and high-precision structural steel pipes for automobiles, tractors and aviation. 沿其横截面的周边上无接缝的钢管。无缝异型钢管厂根据生产方法不同分为热轧管、冷轧管、冷拔管、挤压管、顶管等,均有各自工艺规定。材质有普通和优质碳素结构钢(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。按用途分为一般用途的(用于输水、气管道和结构件、机械零件)和专用的(用于锅炉、地质勘探、轴承、耐酸等)两类。

Seamless steel pipe along the circumference of its cross section. Seamless special-shaped steel pipe plant is divided into hot-rolled pipe, cold-rolled pipe, cold-drawn pipe, extruded pipe, pipe jacking and so on according to different production methods, and each has its own process regulations. The materials are 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. According to their use, they are divided into two categories: general use (for water conveyance, gas pipeline and structural components, mechanical parts) and special use (for boilers, geological exploration, bearings, acid resistance, etc.).

无缝异型钢管用途很广泛。一般用途的无缝异型钢管由普通的碳素结构钢、低合金结构钢或合金结构钢轧制,产量最多,主要用作输送流体的管道或结构零件。.2、根据用途不同分三类供应:a、按化学成分和机械性能供应;b、按机械性能供应;c、按水压试验供应。按a、b类供应的钢管,如用于承受液体压力,也要进行水压试验。3、专门用途的无缝管有锅炉用无缝管、化工电力用,地质用无缝异型钢管及石油用无缝管等多种。

Seamless profiled steel tubes are widely used. Seamless special-shaped steel pipes for general use are rolled by common carbon structural steel, low alloy structural steel or alloy structural steel, with the largest output. They are mainly used as pipes or structural parts for conveying fluids. 2. According to different uses, there are three types of supply: A. supply according to chemical composition and mechanical properties; B. supply according to mechanical properties; C. supply according to hydraulic test. For steel pipes supplied according to category A and b, if they are used to withstand liquid pressure, hydrostatic tests should also be carried out. 3. Seamless pipes for special purposes include seamless pipes for boilers, chemical power, seamless special-shaped pipes for geology and seamless pipes for petroleum, etc.

无缝异型钢管具有中空截面,大量用作输送流体的管道,如输送石油、天然气、煤气、水及某些固体物料的管道等。钢管与圆钢等实心钢材相比,在抗弯抗扭强度相同时,重量较轻,是一种经济截面钢材。

Seamless special-shaped steel pipe has hollow section, which is widely used as pipeline for conveying fluids, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe has lighter weight when its bending and torsional strength is the same, so it is an economic section steel.

广泛用于制造结构件和机械零件,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用钢管制造环形零件,可提高材料利用率,简化制造工序,节约材料和加工工时,已广泛用钢管来制造。

It is widely used in manufacturing structural and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction. It can improve material utilization, simplify manufacturing process, save material and processing time. Steel pipe has been widely used in manufacturing.
