How to calculate the water stop screw, and introduces the calculation method of the water stop screw.

Calculation of water stop screw, want to know how to calculate the price of water stop screw? Also want to know how to calculate the diameter and length of the water stop screw? For example, calculate the water stop screw according to the price, taking the traditional old water stop screw as an example?

The price of water stop screw is determined by the type of water stop screw, and the price consists of the material cost and processing cost of each part of water stop screw. Price calculation of the first-class water stop screw: screw length * unit price+water stop positioning piece+processing fee (thread processing+water stop welding), while price calculation of the third-class water stop screw: inner rod cost+outer rod cost *2+ joint nut cost *2+ processing fee (thread processing+water stop welding).

I hope the above can help you. If you need to know more about other aspects of the calculation of water stop screws, you can search my name to find a detailed answer for you. thank you
