        2022-04-26

        無縫鋼管根據用途不同, 有厚壁無縫鋼管和薄壁無縫鋼管。無縫鋼管用途很廣泛。

        1、一般用途的無縫鋼管根據材質,由普通的碳素結構鋼、低合金結構鋼或合金結構鋼軋制。比如10號、20號等低碳鋼制造的無縫管,主要用作蒸汽、煤氣、液化氣、天然氣、各種石油產品及各種其他氣體或液體的輸送管道;45、40Cr等中碳鋼制造的無縫管,主要用來制造各種機器配件及管道配件。

        2、一般用途的無縫鋼管也分按化學成分和機械性能供應,按水壓試驗供應。承受流體壓力的無縫鋼管,應保證水壓試驗合格。

        3、專門用途的無縫管用于鍋爐、地質勘探、軸承、耐酸等。如石油地質鉆探管、石油化工用的裂化管、鍋爐管、軸承管以及汽車、拖拉機、航空用高精度結構鋼管。

        Seamless steel pipe has thick wall seamless steel pipe and thin wall seamless steel pipe according to different purposes. Seamless steel pipe is widely used.

        1. Seamless steel pipes for general purposes are rolled from ordinary carbon structural steel, low alloy structural steel or alloy structural steel according to the material. For example, seamless pipes made of low carbon steel such as No. 10 and No. 20 are mainly used as transmission pipelines for steam, gas, liquefied gas, natural gas, various petroleum products and various other gases or liquids; Seamless pipes made of medium carbon steel such as 45 and 40Cr are mainly used to manufacture various machine accessories and pipe accessories.

        2. Seamless steel pipes for general purposes are also supplied according to chemical composition and mechanical properties and hydrostatic test. Seamless steel pipes bearing fluid pressure shall be qualified in hydrostatic test.

        3. Special purpose seamless pipe is used for boiler, geological exploration, bearing, acid resistance, etc. Such as petroleum geological drilling pipe, cracking pipe for petrochemical industry, boiler pipe, bearing pipe and high-precision structural steel pipe for automobile, tractor and aviation.
