 由整块金属制成的外表上没有接缝的钢管,称为无缝钢管。根据生产方法,无缝管分热轧管、冷轧管、冷拔管、挤压管、顶管等。依照断面形状,无缝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。
    分类
 
    沿其横截面的周边上无接缝的钢管。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、低合金钢合金钢、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。
 
   用途
 
   无缝钢管用途很广泛。一般用途的无缝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。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ab类供应的钢管,如用于接受液体压力,也要进行水压试验。专门用途的无缝管有锅炉用无缝管、化工电力用,地质用无缝钢管及石油用无缝管等多种。
 
   无缝钢管具有中空截面,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,抗弯抗扭强度相同时,重量较轻,一种经济截面材。


A seamless steel tube is a steel tube made from a piece of metal that has no seams on the outside. According to the production method, seamless pipe is divided into hot-rolled pipe, cold-rolled pipe, cold-drawn pipe, extruded pipe, pipe jacking and so on. According to the cross-section shape, seamless steel tube is divided into two kinds of circular and special-shaped, special-shaped Tube Has Square, Oval, triangle, hexagon, melon seed, Star, with wing tube many kinds of complex shapes. The maximum diameter is 650 mm and the minimum diameter is 0.3 mm. There are thick-walled tubes and thin-walled tubes, depending on the application. Steel tubes without seams along the perimeter of their cross-section. According to the different production methods, it is divided into hot-rolled pipe, cold-rolled pipe, cold-drawn pipe, extruded pipe, pipe jacking, etc. . Materials are ordinary and high-quality carbon structural steel, low-alloy steel alloy steel, stainless acid-resistant steel and so on. According to the usage, it can be divided into general use for water conveyance, gas pipeline and structural parts, mechanical parts and special use for boiler, geological exploration, bearing, acid-proof, etc. . USES: seamless steel tubes are used for a wide range of purposes. General purpose seamless steel tubes are rolled from plain carbon, low alloy, or alloy structural steels, with the largest output, and are used primarily as pipes or structural parts for conveying fluids. There are three types of supply according to their use: A supply according to chemical composition and mechanical properties, B supply according to mechanical properties and C supply according to water pressure test. Steel pipes supplied in Class AB shall also be subjected to hydraulic tests if they are to be subjected to liquid pressure. The special purpose seamless tube has the boiler uses the seamless tube, the chemical power uses, the geology uses the seamless steel tube and the petroleum uses the seamless tube and so on many kinds. Seamless steel pipe with hollow section, a large number of pipes used for conveying fluid, such as oil, natural gas, gas, water and some solid materials, such as pipes. Compared with solid steel such as round steel, steel pipe has the same bending and torsion strength and light weight. It is an economical cross-section material.
