Introduction:
This cold drawn splined steel pipe is made by high quality structural carbon steel pipe. After multiple cold drawn process, this tube have tiny tolerance and high mechanical property.
Application:
Spline coupling consists of internal splines and external splines. The inner and outer splines are multi-toothed parts, the splines on the inner cylinder surface are internal splines, and the splines on the outer cylinder surface are external splines.
