Development Trend And Use Of Seamless Steel Tubes

With the continuous improvement of the pipe material technical indicators in the market, the technical level of the existing seamless steel pipe production process can no longer meet the requirements, and the development of other scientific and technological fields will inevitably promote the qualitative transformation of the production process, so new production process routes are constantly emerging. It is inevitable.

The mutual competition of the production process lines is also the driving force for the continuous development of the production process. At the same time, relevant technical standards should also be synchronized with the needs of the market, and new technical standards that meet market demands will be continuously introduced. The new standards will involve more and more content, the indicators will become more and more strict, and the comprehensive performance requirements of the pipes will be more and more complete.

Due to the different materials and processing methods used, thick-walled seamless pipes and welded pipes differ in many aspects such as performance and dimensional accuracy. In terms of use alone, the main advantages of thick-walled seamless pipes are mechanical properties, anti-crushing performance, and uniform corrosion resistance. The disadvantage is that the wall thickness is low. The advantage of the welded pipe is that the wall thickness is highly accurate, and the disadvantage is the weld. The mechanical properties and corrosion resistance of the place are lower than other parts.

From the production point of view, the thick-walled seamless pipe has a low single weight, low yield and high equipment investment; the production efficiency of the welded pipe is high and the equipment is relatively simple. At present, the application of welded pipes is becoming more and more widely in many fields, and thick-walled seamless pipes are developing in the aspects of high pressure, high pressure, tensile strength, compression resistance, high corrosion resistance and high wear resistance.

The use of steel pipe to make ring parts can improve the utilization of seamless steel pipes and simplify the production process, save data and processing, if rolling bearing rings, etc., has been widely used in steel pipes.

Steel pipes are still a lack of information on various conventional weapons. If the barrels and barrels are to be made of steel pipes. The steel pipe of the road shot blasting machine can be divided into a round pipe and a special-shaped pipe according to the shape of the cross-sectional area. Because the circumference is the largest under the condition that the circumference is flat, a circular tube can transport more fluid!

Many of the seamless steel tubes are used to transport fluid pipes, similar to spiral submerged arc welded steel pipes for pressurized fluid transport, such as pipes for oil and natural gas and certain solid materials for gas and water. Compared with solid steel pipe and round steel, it is a kind of economical section steel when the bending and torsional strength is the same. It is used for making structural parts and mechanical parts, such as oil. Drill pipe and car drive shaft, bicycle frame and steel scaffolding for construction top.
