High-strength impact-resistant seamless steel pipe and manufacture process thereof
The invention discloses a high-strength impact-resistant seamless steel pipe and a manufacture process thereof. The high-strength impact-resistant seamless steel pipe comprises an outer pipe, a middle pipe and an inner pipe, a first interlayer between the middle pipe and the inner pipe is filled with a plurality of buffer supports, the rest positions of the first interlayer are filled with shock absorption particles, and each buffer support comprises an elastic top plate. The top faces of the elastic top plates are in contact with the inner wall of the middle pipe, a buffer rod is installed on the bottom face of each elastic top plate, a plurality of buffer rods are connected to the outer sides of the elastic top plates and the bottom ends of the buffer rods, and a buffer layer is arranged in a second interlayer between the middle pipe and the outer pipe. The buffering supports and the shock absorption particles arranged between the middle pipe and the inner pipe cooperate so that the whole force impact on the steel pipe can be buffered in a multi-layer mode, and external and internal impact of the middle pipe can be further buffered through the arrangement of foam carbon and the energy absorption and shock absorption balls. The problem that the steel pipe is broken or deformed due to impact of internal and external force on the steel pipe is solved, and therefore the service life of the steel pipe is prolonged.
本发明公开了一种高强度耐冲击无缝钢管及其制备工艺，包括外管、中管、内管，所述中管与内管之间的第一隔层内填充安装有若干缓冲支架，且第一隔层的其余位置填充有吸震颗粒，所述缓冲支架包括弹性顶板，所述弹性顶板顶面与中管内壁接触设置，所述弹性顶板底面安装有缓冲杆，所述弹性顶板外侧与缓冲杆底端连接设置有多个缓冲杆，所述中管与外管之间的第二隔层内设有缓冲层。本发明中管和内管之间设置的缓冲支架与吸震颗粒相配合可以对钢管整体力冲击进行多层的缓冲，泡沫碳素和吸能减震球的设置可以对中管外部和内部的冲击进行进一步的缓冲，解决了因内外力对钢管的冲击导致钢管破裂或变形的问题，从而延长了钢管的使用寿命。
