The thickness and breadth of the steel strip is determined according to different pipe diameter and ringstiffness class requirements.
加强钢带的厚度与宽度根据管材直径、环刚度要求不同而分别设计确定。
2
The pipeline has the advantages of reasonable structure, saving materials, solid welding by the melt adhesive, high ringstiffness, etc.
本发明具有结构合理、节省原料、熔 胶焊接牢固、环刚度高等优点。
3
The main reinforcing rib is protected against being destroyed in the processing and applying process, thereby enhancing the ringstiffness of a straight ribbed pipe wound by glass-reinforced plastics.
