Seamless 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 MoreAnti-corrosion steel pipes generally refer to the use of special processes to carry out anti-corrosion treatment on ordinary steel pipes (such as seamless pipes, welded pipes), so that the steel pipes have certain anti-corrosion properties. Corrosion ability is generally used for waterproof, anti-rust, anti-acid and alkali, anti-oxidation and other characteristics. Generally speaking, PE anti-corrosion steel pipe refers to polyethylene…
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 MoreThere are two categories of factors that affect the quality of seamless tubes: steel quality and rolling process factors. Many factors of the rolling process are discussed here. The main influencing factors are: temperature, process adjustment, tool quality, process cooling and lubrication, removal and control of sundries on the surface of rolled pieces, etc. 1. Temperature Temperature is the…
Read MoreThe uneven wall thickness of the seamless tube(SMLS) is mainly manifested in the phenomenon of uneven wall thickness of the spiral shape, uneven wall thickness of the straight line, and thicker and thinner walls at the head and tail. The influence of continuous rolling process adjustment of seamless tubes is an important factor leading to uneven wall thickness of…
Read MoreStainless steel seamless pipe is a long strip of steel with a hollow section and no seams around it. The thicker the wall thickness of the stainless steel seamless pipe, the more economical and practical it is, and the thinner the wall thickness, the higher its processing cost will be. Stainless steel seamless pipes are very similar to cs…
