Torque Chart For Flanges

Torque Chart For Flanges - Web welcome to this interactive flange bolting calculator from hytorc.the program computes recommended torque values , bolting patterns, tool selection and pump pressure settings for standard asme b16.5 and api 6a flanges under normal assembly conditions. Web bolt yield should be at least 80,000 psi. Flange rating:ansi b16.5, class 600. The torque values are applicable for the type of gasket specified and bolts, nuts and washers should be free from damage, rust etc. The final torque value accounts for 10% bolt relaxation. Just enter the flange size, class, and type and the app instantly populates the correct values from the flange bolt size chart and the flange torque sequence chart, along with wrench size. Based on using weldneck flanges & lubricated stud bolts with a 0.15 friction factor.***. Web however, there is no direct method of measuring this load on the gasket, but the applied torque on the flanged bolts can be measured and controlled. Web a complete torque tightening sequence with charts for class 150 to 2500 flanges. Web flange bolt size chart and torque patterns.
