Application |
Conehead is the components of bolt ball steel truss,welded to the end of steel pipe,the screw of high strength bolt goes through the bottom hole into bolt ball,nut is in conehead,the same function with “seal board”,when steel pipe diameter is small to use “seal board”,when steel pipe diameter is big to use”conehead that can avoid from collide with pipe steel. |
