厚壁方管的弯曲度如何避免

发布时间:2022-09-14 来源:/

厚壁方管是制造和日常生活主要的一种方管的种类,它在管材中归属于较为牢固和结实的一种主要的板材。厚壁方管在使用中也是会碰到弯曲形变的这种情况的,济南方管的弯曲度如何避免,要从下面的一些方法做好预防:
Thick walled square tube is a kind of square tube mainly used in manufacturing and daily life. It belongs to a kind of main plate which is relatively solid and solid. The thick wall square pipe will also encounter bending deformation in use. How to avoid bending of Jinan square pipe, the following measures should be taken to prevent it:
(1)选用先外喷后内喷的逐层冷拔加工工艺。因为厚壁方管的内洒水是以厚壁方管的一端流入另一端,厚壁方管在两边的冷拔速率不一样,从而造成厚壁方管弯曲。可选用先开展外洒水冷拔,促使厚壁方管表面生变化,再用内洒水开展降温的办法,防止厚壁方管弯曲变形,内洒水比外喷头的延迟时间可延长2~10s。
(1) The layer by layer cold drawing process of external spraying followed by internal spraying is selected. Because the inner watering of the thick wall square tube flows from one end of the thick wall square tube to the other end, the cold drawing rate of the thick wall square tube on both sides is different, resulting in the bending of the thick wall square tube. The external watering and cold drawing can be carried out first to promote the change of the surface of the thick wall square pipe, and then the internal watering can be used to carry out the cooling to prevent the bending and deformation of the thick wall square pipe. The delay time of the internal watering can be extended by 2~10s compared with the external sprinkler.
(2)降低厚壁方管在转动轮上的悬出端长度。根据有效的转动,合理的布局及厚壁方管长短操纵,将厚壁方管顶端悬出量操纵在≤600mm,可合理减少热处理时的向心力,减少厚壁方管弯曲度。
(2) Reduce the length of the overhanging end of the thick wall square tube on the rotating wheel. According to effective rotation, reasonable layout and length control of thick wall square tube, the overhang of the top of thick wall square tube is controlled at ≤ 600mm, which can reasonably reduce the centripetal force during heat treatment and reduce the bending of thick wall square tube.

(3)对操纵转动轮转速比进行调整。
(3) Adjust the steering wheel speed ratio.
(4)操纵转动轮核心。转动轮核心误差对厚壁方管的热处理时弯曲度有比较大影响。经科学研究,转动轮核心偏差应调节在0~5mm。
(4) Manipulate the turning wheel core. The core error of the rotating wheel has a great influence on the bending of thick walled square tubes during heat treatment. Through scientific research, the core deviation of the rotating wheel should be adjusted within 0~5mm.
(5)操纵內外洒水量及匀称性。油气井管热处理制冷选用外表层制冷加内径向喷涌方法,外洒水量要均匀,内洒水量及内喷头的对中度合理也是厚壁方管水淬时影响弯曲度的关键要素。
(5) Control the internal and external spraying water volume and uniformity. Oil and gas well pipe heat treatment refrigeration adopts the method of external layer refrigeration and internal diameter spraying. The external spraying water volume should be uniform. The reasonable alignment of internal spraying water volume and internal nozzle is also the key factor affecting the bending degree of thick walled square pipe during water quenching.
碰到厚壁方管的弯曲和形变的情况,如果是可以矫正的话,那么厚壁方管是可以再次使用的,否则的话厚壁方管会很大程度上影响使用。更多相关注意事项就来我们网站进行咨询。
In case of bending and deformation of the thick walled square tube, if it can be corrected, the thick walled square tube can be used again, otherwise, the use of the thick walled square tube will be greatly affected. More relevant precautions come to our website Consult.
