 The properties of seamless tubes include yield point, tensile strength, hardness index, reduction of area, and elongation after fracture. 1. Yield point For metal materials with yield phenomenon, the stress at which the sample can continue to elongate without increasing the force (keep constant) during the stretching process is called the yield point. If the force drops, the upper and lower yield points should be distinguished. The unit of yield point is N/mm2 (MPa). 2. Tensile strength The stress (σ) obtained by dividing the force (Fb) that the sample bears when it is broken by the original cross-sectional area (So) of the sample during the stretching process is called the tensile strength (σb), and the unit is N /mm2 (MPa). It represents the ability of metal materials to resist damage under tension. 3. Hardness index The ability of metal materials to resist the indentation of hard objects on the surface is called hardness. According to different test methods and scope of applica...

 There are many kinds of steel pipes on the market, such as: seam pipes, seamless pipes, etc., but many people do not know the difference, so what is the difference between seamed steel pipes and seamless steel pipes? The seam pipe is also called welded steel pipe, which is nominally named in nominal size. Its commonly used nominal size is DN15~100, and its largest nominal diameter is DN150 (6). Welded steel pipes are also called water and gas pipes because they are often used for the transportation of hot and cold water and gas. Galvanized welded steel pipes are habitually called white iron pipes on construction sites, while non-galvanized welded steel pipes are called black iron pipes. The blanks used for welded steel pipes are steel sheets or strips. The seamless steel pipe is made of perforated whole round steel, and the steel pipe without weld seam on the surface is called seamless steel pipe. According to the production method, seamless steel pipes can be divided into hot-rol...

 The main difference between annealing and normalizing: 1. The cooling rate of normalizing is slightly faster than that of annealing, and the degree of supercooling is larger 2. The structure obtained after normalizing is relatively fine, and the strength and hardness are higher than that of annealing. The choice of annealing and normalizing: 1. For low carbon seamless steel pipes with carbon content less than 0.25%, normalizing is usually used instead of annealing. Because the faster cooling rate can prevent the low carbon seamless steel pipe from precipitation of free tertiary cementite along the grain boundary, thereby improving the cold deformation performance of the stamping parts; normalizing can improve the hardness of the steel and the cutting performance of the low carbon seamless steel pipe. ; When there is no other heat treatment process, normalizing can refine grains and improve the strength of low carbon seamless steel pipes. 2. The medium carbon cold-drawn seamless st...

 What are the factors that affect the quality of American Standard seamless tubes? 1. Temperature Temperature is the main factor affecting the quality of American Standard seamless steel tubes. First of all, the uniformity of the heating temperature of the tube blank directly affects the wall thickness uniformity and inner surface quality of the perforated capillary, which in turn affects the wall thickness quality of the product. Secondly, the temperature and uniformity of the steel pipe during rolling (especially the final rolling temperature) are related to the mechanical properties, dimensional accuracy and surface quality of the product delivered in the hot-rolled state, especially when the billet or billet is overheated or even When overheated, it will cause waste. Therefore, in the production process of hot-rolled seamless pipes, heating and controlling the deformation temperature in strict accordance with the process requirements must be done first. 2.
