JIS无缝管道

Japanese Industrial Standards for steel“></a> </div> <p>Japanese Industrial Standards (JIS) developed by the organization apply to a wide variety of industrial services and technologies such as automobiles, metallurgy, ships and medical equipment</p> <p>The method for making cold-drawn seamless pipes involves taking a round “billet” or bar of steel and boring it in the center, turning it, cutting it, heating it to make it more pliable, then “drawing” it (extruding or pulling it) to make it a longer and thinner tube.</p> <ul> <li><a href=如何测量钢管的长度？
