- Seamless steel tube common senseIn life, many people know the steel pipe and know the existence of a seamless steel pipe. But for seamless steel pipes, many people are limited to knowing this steel. Then let's talk about the understanding of seamless steel pipes. This is a hollow interface with no seam marks on each perimeter. The
- Hot rolling and Cold rolling seamless steel tubesSeamless steel tubes are divided into hot rolling and cold rolling seamless steel tubes. Hot-rolled seamless steel pipe is divided into general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, geo
- Application of seamless steel tube in construction pipeline industryAmong the many pipe materials, the most practical one is the seamless steel pipe. This is a more powerful pipe material, not only because of the wide range of fields and scope of the pipe material, but more importantly, Because the quality of seamless steel pipe is very good, the quality of the seam
- What are the requirements for the quality of tube blanks in the production of precision and cold drawn seamless steel tubes?(1) Structural seamless steel pipe and conveying pipe blank. Including low carbon steel, medium carbon steel and alloy structural steel tube billet, steel number has 10#, 20#, 35#, 45#, and 15Cr, 40Cr, 30CrMnSi, 12CrMoV and so on.(2) Boiler tube blank. Generally, the steel for boiler tube blanks is
- GB 20# seamless steel pipe20# carbon steel belongs to high-quality low-carbon steel in national standard metal materials. Because of its good toughness, plasticity and weldability, it has wide application in China's petrochemical industry, and different 20 carbon steel materials are used. The incidence is also high. However,
- RAY Precision seamless steel pipePrecision seamless steel pipe is a high-precision steel pipe after cold rolling or cold drawing; full name: cold-rolled or cold-drawn precision seamless steel pipe. Because the inner and outer walls of precision seamless steel tubes have no oxidation layer, high pressure and no leakage, high precisi
- Where is the 20# seamless steel pipe used mainly?20# seamless steel pipe is mainly used in what place, some materials manufacturers, material units to this problem is not clear, today RAYMOND precision seamless steel pipe manufacturers to this issue a systematic summary of the problem. 20# seamless steel pipe belongs to universal carbon steel seam
- Development of Technology for Microstructure Control during On-line Heat Treatment Process for Hot-rolled Seamless Steel PipeIn the conventional manufacturing process for the hot-rolled seamless steel pipe, the pipe as rolled was air-cooled down to the ambient temperature. And due to absence of proper on-line microstructure control of the pipe, properties had to be controlled depending on addition of much more alloy eleme
- Formation Causes of 15Mn Seamless Steel Tube Banded StructureIn the production of 15Mn seamless steel tube with hot rolling process, the pipe body has obvious banded structure.15Mn seamless steel pipe, in the metallographic examination found that the matrix exists ribbon structure. Why does this happen?Steel tube production process: Converter smelting → LF fu
- Small diameter seamless steel tubeSmall diameter seamless steel pipes refer to seamless steel pipes with a diameter of ≤ 159 mm. According to the different production equipments, it is divided into three grades: diameter Φ76 mm, Φ76~114 mm and Φ114~159 mm. Small-diameter seamless steel tubes are widely used, including general-purpos
