Seamless steel pipe is made of perforated hot rolled steel pipe without weld. Sometimes the hot-worked pipes need to be further cold-worked in order to obtain the corresponding shape and size. Carbon steel pipes are generally made of round, square and flat after multiple rolling.
Seamless steel pipe is the most widely used pipe in petrochemical plant nowadays. The use of carbon steel pipes is more extensive. At the same time, carbon steel pipe is the main requirement of its chemical composition is carbon content, seamless steel pipe is a large type, refers to the seamless steel pipe, a wide range.
Brief Introduction of Carbon Steel Pipe: Carbon Steel Pipe refers to the steel pipe with welded surface after bending and deformation of steel strip or steel plate into circular, square and other shapes. The billet used for ASTM A53 API 5L sch 40 st35.8 seamless carbon steel pipe is steel plate or strip steel. Since the 1930s, with the rapid development of high quality strip continuous rolling production and the progress of welding and inspection technology, the quality of weld seam has been improved continuously, and the variety and specification of carbon steel pipe has been increasing day by day, and seamless steel pipe has been replaced in more and more fields. carbon steel pipe has lower cost and higher production efficiency than seamless steel pipe.
