Flange Bolt Chart - Size & Torque
Look up flange bolt sizes and torque patterns in three taps with Flange Bolt. Just enter the flange size, type, and class, and the tool instantly shows the ASME values for: 1. Number of studs. 2. Diameter of studs. 3. Length of studs. 4. Torque pattern. 5. Suggested torque amount.
Flange Bolt Torque Calculation and Pipe Flange Bolt Torque Chart
Pipe Flange Bolt Torque Chart. Even though flange blot toque calculation is possible, they are normally selected from the pipe flange bolt torque chart. The entire bolt pattern shall be tightened at least three times around the flange at 30%, 70%, and 100% of the torque value.
Flanges - Bolting Torque Tables - Table 1 - ASTM A193 and ASTM …
The torque values are approved for spiral wound graphite and PTFE filled gaskets. The Final Torque Value accounts for 10% bolt relaxation. The yield strength for strain-hardened bolts varies with diameter.
Round 1: Tighten to 20% to 30% of Target Torque usind cross pattern. Check flange gap around circumference for uniformity. Round 2: Tighten to 50% to 70% of Target Torque usind cross pattern. Round 3: Tighten to 100% of Target Torque usind cross pattern. Round 4: Continue tightening the bolts, but on a circular clockwise pattern until no
These bolt torque values are intended for use as guidelines only and are based on ideal conditions, perfect flanges, flange alignment & new well lubricated bolts/nuts according to the national boiler code, installed in accordance with the Central Plastics Company Flange Installations Guidelines. .

A complete torque tightening sequence with charts for class 150 to 2500 flanges. In this article, you will learn about the torque sequence of pipe flanges.
ASME Flange Bolt Torque Chart (Calculation Formula
Flange torque is the force needed to assemble or disassemble connected flanges. It depends on factors like flange size, material, overlap area, and gasket type. Suitable flange torque should be based on specific circumstances and relevant standards, with adjustments as needed.
Flange Torque Charts - Flange Bolt Chart
Flange Torque Charts listed by NPS and by Flange Class. Charts for NPS 0.5-60 and Class 150-2500.
The user is able to select from ANSI/AWWA C207 (2013b) flange classes, gasket materials, and flange diameters. Based on the users input, the torque calculator generates a recommended torque range to select the appropriate torque value for the application. It also offers warning to
