Before the users consulted about the physical properties of seamless tubes, but there are many people are still confused about this, do not know what it is, Hangzhou Hengxin Steel Co., Ltd. to introduce us to the physical properties of seamless tubes.
The characteristics of seamless tubes:
The thicker the wall of the product, the more economical and practical it is, and the thinner the wall is, the higher the processing cost will be. Secondly, the technology of this product determines its limited performance. Generally, the accuracy of seamless steel pipes is low: the thickness of the wall is uneven, the brightness of the inner surface of the tube is low, the cost of the fixed ruler is high, and the internal surface is not easy to remove; Thirdly, its detection and shaping must be handled offline. Therefore, it embodies its superiority in high pressure, high strength, and mechanical structure materials.
Seamless tube appearance quality
The inner and outer surfaces of seamless tubes shall be free from cracks, folding, cracking, cracking, rolling, layering and scarring defects, which shall be completely removed(except for tubes used for machining) and shall not be removed so that wall thickness and outer diameter exceed negative deviation. Other minor surface defects that do not exceed the permissible negative deviation may not be removed.
D, straight channel allows depth. Hot rolling, hot extrusion steel pipes, not more than 5 % of the nominal wall thickness with a diameter of less than and equal to 140 mm, and a maximum depth of not more than 0.5 mm; Cold drawn(rolled) steel pipes are not greater than 4 % of the nominal wall thickness and the maximum depth is not more than 0.3 mm.
The above is the physical properties of seamless pipes introduced to us by Hangzhou henxin steel Co., Ltd.. After the above sharing of Hangzhou henxin steel Co., Ltd., I believe many people have a certain understanding of this, hope to help you.
