KF-913 in ASME Division III has been written
If differences are noted between specified and measured compression at these checkpoints and there is reason to presume that the final final compression will not be reached if the original program is followed, a change may be made in the remaining program by increasing the specified wire force by Not more than 10%. The final difference between originally specified and measured compression shall not exceed 5%.
It is mentioned that if our winding can not reach the final compression amount, it can be modified by increasing the pulling force. The tension error mentioned here does not exceed 10%. If it is wound with constant tension, it means the first one. When the layer is wound, the amount of pre-tightening is insufficient, and the force of increasing no more than 10% in the second layer is reasonable, or the force to be subsequently increased must be controlled at 10% of the design tension.
Follow up with two possibilities for the problem:
1. 10% means the error between the next layer and the upper layer
2. 10% of the error means that if the theoretical calculation of each layer value, the amount of each layer actually entangled can not exceed 10% of the theoretical calculation.
