對于無縫異型鋼管產(chǎn)品的破壞是否為氫脆所造成,有一個較簡單的判斷方法,那就是如果螺絲或螺栓在裝置后1到48小時內(nèi)破壞,且其破壞在頭部與桿部以及無縫異型鋼管的交接位置,那大概就是研究調(diào)查結果顯示,在測試無縫異型鋼管材料對氫脆化的感受性是直接與無縫異型鋼管本身氫侵入含量有關(侵入的型態(tài)與有效性0.因此燒烤過程中時間溫度的關系不但取于無縫異型鋼管的成份和組織而且也和電鍍過程息息相關,另外大部分高強度的無縫異型鋼管,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無縫異型鋼管脆化,氫脆化測試僅是最后的手段,重要的是事前的防范以預防及降低重大的損失.當制造過程管制(包括電鍍處理過程)將可使氫脆化的機率降到最低.

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.

無縫異型鋼管按形狀分為：外六角內(nèi)圓鋼管、外圓內(nèi)六角鋼管、內(nèi)外六角鋼管、平橢圓鋼管、橢圓鋼管、三角管、L型鋼管、八角管、蘑菇型管、面包型管、D型管、凹型管、凸型管、傘型管、P型管、元寶型管等異型管，異型鋼管形狀是根據(jù)用戶需要而生產(chǎn)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.
