Also, the shoulder seal may not be properly seated, resulting in mud leaking through the tool joint, causing a washout. Acme/Stub Acme Thread Torque and Axial Load Calculation Once thread box/pin nose has stopped moving and the box/pin makes contact at the internal or external shoulder (see Figure 4 and 5), additional torque is translated into tension or compression causing an axial stress applied across the thread relief of the box for contact at the internal In this situation the wall thickness is defined by maximum thread root and minimum OD for the box and minimum thread root and maximum ID for the pin. It is very important therefore, that the correct make-up torque is applied to the tool joints. Roscas Acme-Non Cas - Read online for free. Tie rods are structural units that prevent the separation of two parts and are used in numerous industries and applications. stub ACME torque. The body connection in that past has been an API connection ( with non-standard bevel diameters) that are rated slightly higher in torsion and tension than the double shouldered connections. Exceeding the torsional yield strength of the connection by applying too much torque to the tool joint could cause the shoulders to bevel outward or the pin to break off the box. We believe that the new Videx machine will help us enter some markets for higher volume worklikely for the heavy equipment and fluid power industries.
