 由整塊金屬制成的外表上沒有接縫的鋼管,稱為無縫鋼管。根據生產方法,無縫管分熱軋管、冷軋管、冷拔管、擠壓管、頂管等。依照斷面形狀,無縫鋼管分圓形和異形兩種,異形管有方形、橢圓形、三角形、六角形、瓜子形、星形、帶翅管多種復雜形狀。最大直徑達650mm最小直徑為 0.3mm根據用途不同,有厚壁管和薄壁管。
    分類
 
    沿其橫截面的周邊上無接縫的鋼管。根據生產方法不同分為熱軋管、冷軋管、冷拔管、擠壓管、頂管等,均有各自工藝規定。材質有普通和優質碳素結構鋼、低合金鋼合金鋼、不銹耐酸鋼等。按用途分為一般用途的用于輸水、氣管道和結構件、機械零件)和專用的用于鍋爐、地質勘探、軸承、耐酸等)兩類。
 
   用途
 
   無縫鋼管用途很廣泛。一般用途的無縫鋼管由普通的碳素結構鋼、低合金結構鋼或合金結構鋼軋制,產量最多,主要用作輸送流體的管道或結構零件。根據用途不同分三類供應:a按化學成分和機械性能供應;b按機械性能供應;c按水壓試驗供應。按ab類供應的鋼管,如用于接受液體壓力,也要進行水壓試驗。專門用途的無縫管有鍋爐用無縫管、化工電力用,地質用無縫鋼管及石油用無縫管等多種。
 
   無縫鋼管具有中空截面,大量用作輸送流體的管道,如輸送石油、天然氣、煤氣、水及某些固體物料的管道等。鋼管與圓鋼等實心鋼材相比,抗彎抗扭強度相同時,重量較輕,一種經濟截面材。


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.
