对于无缝异型钢管产品的破坏是否为氢脆所造成,有一个较简单的判断方法,那就是如果螺丝或螺栓在装置后1到48小时内破坏,且其破坏在头部与杆部以及无缝异型钢管的交接位置,那大概就是研究调查结果显示,在测试无缝异型钢管材料对氢脆化的感受性是直接与无缝异型钢管本身氢侵入含量有关(侵入的型态与有效性0.因此烧烤过程中时间温度的关系不但取于无缝异型钢管的成份和组织而且也和电镀过程息息相关,另外大部分高强度的无缝异型钢管,共而快速跌落.
For seamless special-shaped steel pipe products, there is a simpler method to judge whether the failure is caused by hydrogen embrittlement. That is, if the screw or bolt is damaged within 1 to 48 hours after the installation, and the failure is at the joint position between the head and the rod and seamless special-shaped steel pipe, it is probably the result of research and investigation that the sensitivity of seamless special-shaped steel pipe materials to hydrogen embrittlement is direct and seamless in testing. The hydrogen intrusion content of the special-shaped steel pipe is related to its intrusion type and validity (0. Therefore, the relationship between time and temperature during barbecue process is not only determined by the composition and structure of the seamless special-shaped steel pipe, but also closely related to the electroplating process. In addition, most of the high strength seamless special-shaped steel pipe falls rapidly. 有很多原因可能使得无缝异型钢管脆化,氢脆化测试仅是最后的手段,重要的是事前的防范以预防及降低重大的损失.当制造过程管制(包括电镀处理过程)将可使氢脆化的机率降到最低.
There are many reasons for brittleness of seamless special-shaped steel pipe. Hydrogen embrittlement test is only the last means. It is important to prevent and reduce heavy losses beforehand. When manufacturing process control (including electroplating process) will reduce the probability of hydrogen embrittlement to the minimum.
无缝异型钢管按形状分为：外六角内圆钢管、外圆内六角钢管、内外六角钢管、平椭圆钢管、椭圆钢管、三角管、L型钢管、八角管、蘑菇型管、面包型管、D型管、凹型管、凸型管、伞型管、P型管、元宝型管等异型管，异型钢管形状是根据用户需要而生产的。
Seamless special-shaped steel pipe can be divided into outer hexagonal inner tube, outer hexagonal inner tube, inner and outer hexagonal tube, flat elliptical tube, elliptical tube, triangular tube, L-shaped tube, octagonal tube, mushroom tube, bread tube, D-shaped tube, concave tube, convex tube, umbrella tube, P-shaped tube, Yuanbao tube and other special-shaped tubes according to the shape of the tube is produced according to the needs of users.
