Baotou seamless pipe mill provides knowledge of Q345B seamless steel pipe -Q345B seamless steel pipe price is a lot of classification methods. According to manufacturing process classification: hot-rolled seamless pipe and cold-rolled seamless pipe. Classified by purpose: general structure is seamless Steel tubes, seamless steel tubes for conveying fluids, seamless steel tubes for medium and low pressure boilers, seamless steel tubes for high pressure boilers, by material: high quality carbon...
Hot recommend: Shandong seamless pipe mills share hot-rolled seamless steel pipe and cold-rolled seamless steel pipe. Cold-rolled seamless steel pipe is often a small diameter, hot-rolled seamless steel pipe is often a large diameter. The precision of cold rolled seamless steel tubes is higher than that of hot rolled seamless steel tubes, and the price is also higher than that of hot rolled seamless steel tubes. Seamless steel pipe: Because of its different manufacturing processes, it is...
General seamless steel pipe production process can be divided into cold-drawn seamless steel pipe and hot-rolled seamless steel pipe. The production process of cold-rolled seamless steel pipe is generally more complicated than hot-rolled steel. The pipe blank must be firstly rolled by three rollers. After pressing, the sizing test is performed. If the surface does not respond to cracks, the circular tube is cut by a mower to cut a blank having a length of about one meter. Then enter the...
Alloy seamless steel pipe is a seamless steel pipe, its performance is much higher than the average seamless steel pipe, which contains more Cr inside the steel, its high temperature, low temperature, corrosion-resistant properties of other seamless steel pipe Compared to the alloy pipe in the petroleum, chemical, power, boiler and other industries more widely used. Alloy seamless steel pipe contains elements of silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium,...
