How to produce hot-rolled seamless steel pipe? The production process of hot-rolled seamless steel pipe includes several basic processes such as blank preparation before rolling, pipe heating, piercing, rolling, sizing and reducing, pipe cooling and finishing. There are three main deformation processes in the production of hot-rolled seamless steel pipes: piercing, rolling and sizing/reducing. Their respective technical purposes and…
Read MoreCarbon steel seamless pipe (cs smls pipe) is a long steel pipe with hollow section and no joints around it; it is widely used in oil transportation, natural gas, gas, water and the transportation of certain solid materials. Compared with other steel pipes, the cs seamless pipe has a strong advantage in bending resistance; and the weight of the…
Read MoreWelded steel pipe and seamless steel pipe are two of the most commonly used types of steel pipes in the industry. Both are made from steel, but there are significant differences between the two that affect their performance, reliability, and overall quality. In this article, we will take a closer look at the differences between welded steel pipes and…
Read MoreSeamless pipe (SMLS) is a steel pipe made of a single piece of metal with no joints on the surface. It is made of a steel ingot or a solid tube blank through perforation to form a capillary tube, and then hot-rolled, cold-rolled or cold-drawn. The characteristics of seamless steel pipes are different from other steel pipes. They are…
Read MoreSpiral steel pipes and seamless steel pipes are relatively common pipes in life, and they are used in house decoration and construction. So what is the difference between spiral steel pipes and seamless steel pipes? What is a spiral steel pipe? Spiral steel pipe (SSAW) is a spiral seam steel pipe made of strip steel coil as raw material,…
Read MoreSeamless tubes are tubes without seams or welds. Seamless steel tubes are considered to be able to withstand higher pressures, higher temperatures, higher mechanical stress and corrosive atmospheres. 1. Manufacturing Seamless steel tubes are manufactured using a number of different methods. The method used depends on the desired diameter, or ratio of diameter to wall thickness, required for the…
Read MoreCross rolling is a rolling method between longitudinal rolling and cross rolling. The rolling of the rolled piece rotates along its own axis, deforms and advances between two or three rolls whose longitudinal axes intersect (or incline) in the same direction of rotation. Cross rolling is mainly used for piercing and rolling of pipes (such as the production of…
Read MoreThe cross-rolling piercing process is the most widely used in the production of seamless steel pipes, and was invented by the German Mannesmann brothers in 1883. The cross-rolling piercing machine includes two-roll cross-rolling piercing machine and three-roll cross-rolling piercing machine. The capillary quality defects produced by cross-rolling and piercing of tube blank mainly include inward fold, outward fold, uneven…
