Seamless steel pipe (smls pipe) is a non-combustible building material, which has the characteristics of earthquake resistance and bending resistance. In practical applications, seamless steel pipes can not only relatively increase the load capacity of buildings, but also meet the needs of architectural design aesthetic modeling, and also avoid the defects that concrete and other building materials cannot be…
Read MoreSeamless steel pipes are often used as raw materials for ring-shaped metal material parts, which not only saves a lot of complicated technological processes, but also greatly reduces the wear and tear of stainless steel plates in the production process and saves product costs. The basic principle of this kind of production and processing is not difficult to understand….
Read MoreThe basic manufacturing process of thick wall P22 seamless alloy pipe is: melting, blank making, extrusion and annealing heat treatment. (1) Smelting P91 steel has high alloy content. How to complete the alloying of steel in a short time is the key of smelting process. P22 seamless alloy pipe is smelted by 50t power electric arc furnace + 5T…
Read MoreWhat is wrought steel Wrought steel material refers to product forms (forged, rolled, ring rolled, extruded…), while forging is a subset of wrought product form. Difference between wrought steel and forged steel 1.The main difference between wrought and forged steel is strength.Forged steels are tougher than wrought steels as they begin as a casting which is then forged which…
Read MoreIndex analysis of mechanical properties of seamless pipes (smls pipe): 1. The performance index analysis of seamless pipe–plasticity. Plasticity refers to the ability of metal materials to produce plastic deformation without being damaged under load. 2. Analysis of performance index of seamless pipe–hardness. Hardness is a measure of the hardness of metal materials. At present, the commonly used method…
Read MoreThere are three main methods of manufacturing tubing that lend their names to tubing classifications. Seamless steel tubes are produced through extrusion. Extruded tubes can be formed in a hot or cold process. Long sections of steel bar are forced through a die that blocks out the intended shape of the tube. As-welded or electric resistant welded (ERW). This…
Read MoreSeamless steel pipe (SMLS pipe) cracks reasons: 1. Raw material factors Inferior tube blanks will have internal and external warping, scars, cracks, etc.; 2. Temperature factor The first important process in the production of seamless steel pipes is heating. Poor heating (unevenness, insufficient temperature, etc.) will cause inner warping, etc.; 3. Equipment factors From the beginning of the furnace,…
