Seamless steel pipe in china and some of its specifications!

發布時間:2020-06-29

Seamless steel pipe in china, also known as straight seam welded pipe, is a kind of welded steel pipe. In terms of service life, seamless steel pipe has a very wide range of applications. As the straight seam steel pipe in china is widely used, there are many specifications in the actual use of the seamless steel pipe in china. Do you know what specifications the seamless steel pipe in china has? Let's see! The straight welded pipe or steel plate is based on the bow chain, and then through the welding points, according to the classification of different welding, the welded pipe can be divided into the following two types, one is directly welded steel pipe, the other is spiral steel pipe. Compared with the spiral welded pipe, the straight welded pipe has many advantages and has been widely used in the service life. Main application: galvanized rectangular pipe, oxygen pipe, wire sleeve, measuring pipe, pipe barrel, deep pipeline, automobile pipe, substation pipe, etc. In the process of using and managing the general welded pipe, the system fluid is mainly transported through the function. This kind of welded pipe is usually made of mild steel, which is easy to weld. The steel material shall conform to the specification of steel pipe and thickened steel pipe. In the actual use and management process, the nominal pressure pipe can be mainly used for pressure, bending and other experiments. Therefore, the pressure pipeline engineering in the production process has design process performance. The total supply time of the enterprise is 4-10 meters, which is not fixed. The thickness of welded pipe shall be the same when different specifications of welded pipe are prepared. The public welded pipe is divided into common pipe and thin-walled pipe, which can be used to produce the automobile transmission shaft of manufacturing enterprises or to transport the fluid and other prefabricated parts. Use thin-walled tubes and lighting equipment in furniture manufacturing to ensure seamless compression and tensile strength of welded steel tubes. Generally, roller belt conveyor can be tested by pressure and deformation. Seamless steel pipe in china, carbon steel alloy rolled according to common structural steel or low angle spiral structure (called forming angle), welded pipe and large diameter welded steel pipe. Spiral welded pipe petrochemical gas transmission project is the most commonly used steel pipe, spiral welded pipe and single side positive and negative pole welding. We should make sure that the hydraulic pipe test, compressive strength and tensile properties.
