Stud Bolt Length No. The torque value is selected as 110 N m in this study. The minimum number of bolts n bmin can now be determined with:. calculation of target torque for bolts (asme pcc-1 ) The Target Torque required to tighten bolting is computed as follows: T = F/2{d n x µbolt + [(µthread +Cos ά x Tan λ )/( Cos ά - (µthread x Tan λ )]}. Possible bolting torque sequences (overview of advantages and disadvantages of all available methods according to ASME PCC-1-2013) 2. 625 80 1-1/4 4 0. Flange Ratings to ASME B16. Description: U-Bolts are U-shaped bolts with two threaded arms protruding from a curved base. Use the following Torque Calculator for ASTM A193 B7 and ASTM A320 L7 bolting, as specified in API 6A , 16A and 17D for flanges. Contact us to find out more information about our sweep loss calculation of industrial flanges. Generally 70 % bolt yield is targeted. But neither the external threads of the bolt nor the internal threads of the nut are exactly. The success of flanged joints depends on applying the correct amount of gasket load and achieving uniform load around the joint. Compared to other fasteners, recommended torque levels for U-bolts are significantly lower. Calculate ASME B31. With dimensions of 42 by 2. These heavy hex bolts are produced to dimensions classified under ASME B18.

Anchor bolts larger than 2 in. - FEA loads for the operating and seating case - FEA loads for the operating only case. readout shows you your torque setting, and then changes to the follow up angle you desire. According to the "Piping and Pipeline Calculations Manual" by Phillip Ellenberger, the ASME developed standard PICC-1 to describe the appropriate way to assemble pipes flanges. 5 or ASME B 16. ASME also sets the standards for flanges and bolt dimensions through the ANSI accredited ASME Standard B 16. Valve Seating Types Selection Guide. The calculation is based on the axial forces balance between the bolt load, the resulting axial force due to the end thrust effect of the internal pressure and the reaction on the gasket. The corresponding maximum bolt torque based on the strength of the bolt can be found using this formula: Hence, the ASTM A307, Grade B bolts are suitable for a resilient gasket target torque range of 60-210 foot-pounds. The calculation method takes into account the elasticity of the connected shell, the thermal expansion between flange and bolts and the effective gasket surface and calculates the required assembly torque for the bolts. This is a nitrogen bearing, 316 stainless steel bolt with a lower carbon content of 0. 10 RTJ Face to Face Dimensions Ball/GGC/Plug. CEN/TC 74 has produced a sepa-rate series of standards, EN 1759-1, EN 1759-3 and EN 1759-4, dealing with the ANSI/ASME based flanges in their original Class designations;.

ASTM A490 Bolt Torque Chart The ASTM A490 is a specification for the bolts set by the ASTM International, a voluntary standards development organizations that sets technical standards for materials. # 4 Neither 15,000 psi compressive stress on the gasket (crush point) or 60,000 psi bolt stress (60% of bolt yield for a A193 B7 bolt) should be exceeded. The final result is that the oversized PD of the part will allow the NoGo gage to thread on (in) the part as long as the root is not shallower than this 25% offset of the major diameter on between the Go and NoGo gages. Clamp load is also known as preload or initial load in tension on bolt. In order to evaluate the load cases, the loads for flange, bolts, gasket and loose flange are determined. The question then becomes how to relate the bolt torque to the bolt tensile stress. But it is easier to specify the. The calculator is generic an can used for imperial and metric units as long as the use of units are consistent. Anchor bolts larger than 2 in.
