The below chart refers to usage in steel. bolts reduces this theoretical gasket crushing force. The load washer will measure the load as torque is applied to the nut. DO NOT REUSE old gasket, or use MULTIPLE gaskets. Torque is the turning force measured in foot-pounds (ft-lb) or inch-pounds (in-lb) applied to tighten (turn) the nut on a bolt. The rotation of a bolt (torque) at some point causes it to stretch (tension). Additionally, the bolts and flanges must be robust enough to prevent warpage, distortion or separa-tion during service. While tightening the bolt with torque wrenches (for pipe / Manway flanges) ensure that tightening load to each bolt is applied as uniformly as possible. The remaining 90% is lost due various forms of friction that occur during the tightening process. Torque and Tension in Bolts: Bolt, one of the most widely used fasteners in the industry, is usually tightened by applying torque to the head and/or nut. B7 Bolts / A194 Gr. Per 1000 pieces.

Flange bolts virtually eliminate the need for washers because the area under the bolt head is wider and creates a larger area for even distribution of pressure. AWWA flanges are normally supplied as flat faced, unless raised face is specified by customer. Hydraulic torque wrench, dial torque wrench, digital torque wrench, they all have tension errors. Durlon RELATED: Torque Value Calculator. Proof load in N. I have the formula but cannot find a way to determine the "allowable stress". Continue tightening in the recommended sequence until the final torque value is reached. When the force is clockwise, its torque is negative, and when it’s moving counterclockwise, it’s positive.
