Torque calculations are based on the simplified formula explained in the current version of ASME PCC-1, Appendix K. The width across flats of a nut is typically 1. Bolt torque calculator metric (vdi 2230) Bolt torque calculator metric. These calculation tools are intended to be used for information and guidance only, they do not replace a detailed design calculation and compliance with all applicable Code requirements. Normal Operating (At 1,200 Initial Bolt Torque Reduced From 535 (Ft. The coefficient of torque is a calculation based on the condition of the fastener and can be affected by lubrication, plating, anti-seize compounds, etc. 1: UNC - UN Course thread, common for up to 1", where bolt diameter size increases with decreasing thread pitch. This problem sometimes causes a conflict when the flange torque calculation of the minimum required torque value to resist hydrostatic end force at the maximum design pressure of the flange is larger than the maximum. 63 38 114 19 115 17 84 27 89 34 102. Popularly used in all assemblies, a standard hex bolt is a staple across the world. In other words, if you double the diameter of the bolt, you need eight times the torque to induce the same stress. These calculations are suitable for assessment of the strength of the flanges. But neither the external threads of the bolt nor the internal threads of the nut are exactly. PIPING PRODUCTS. Size 1" and below shall have UNC threads. Additional grades of A320 bolts exist but are not used frequently enough to list …. In this case there is a total torque that is the sum of each individual torque. AllQDseries torque instruments are accurate to ±4% clockwise and ±6% counterclockwise from 20% of full scale to full scale sLong Life Ratchet Head. LANL Engineering Standards Manual PD342 Chapter 17 Pressure Safety Section D20-B31. A hex drive permits a greater torque load to be applied to the joint over most other drive types. The calculation as per ASME VIII div. It was created to work as a Calculation Report, so it have all the calculation steps with all the equations and values. Dry Torque) Partially Lubricated Bolts; Properly Lubricated Bolts; But before we talk about these items, or get to our torque chart, it is imperative you understand the working definition of K-Factor (or “Nut Factor”).

Calculate my bolt tension based on a percentage of bolt material yield stress (40% is my target), or 0. A torque wrench uses torque as a proxy for bolt tension. Several factors affect how much tension occurs when a given amount of tightening torque is applied. “The big problem with torque is that we have a lot of things going on,” Washington said. These heavy hex bolts are produced to dimensions classified under ASME B18. K = coefficient of friction, D = nominal diameter of bolt and F = axial load. 25,4mm, length between two flanges 150,00 mm, stud length 220 mm required elongation: 0,5 mmThere are several factors that affect the relationship between the applied bolt torque and the resulting bolt tension. Junction Block Tees — These are solid block union fittings to connect two tube/hose assemblies using 4-bolt flange connec-tion, at a junction, to SAE 4-bolt flange port, or three tube/hose assemblies to each other. 15 • Target torque calculation according to ASME PCC-1 Appendix J. QD series torque instruments feature the Snap-on®high strength sealed ratchet head. RECOMMENDED BOLT TORQUE VALUES NOTES: 1. 5) and for Insulating Gaskets ANSI 150 Flange Size No. A torque wrench uses torque as a proxy for bolt tension. Higher loads (than F W) will normally not damage the spring if the load cannot deflect it past the flat position (as in most bolting applications). The flanges are drilled to receive bolts which, if of the proper material, will develop the full flange strength and result in a satisfactory joint at the service intended. HEAVY HEX NUTS ASSEMBLED. 5 - Flanges and Bolt Dimensions Class 150 to 2500 - Diameters and bolt circles for standard ASME B16.

Others include: 8UN - 8 pitch thread, common for bolt/nut larger than 1") UNF - UN Fine thread UNEF - UN Extra Fine thread UNS - UN Special. size Outside. Those parts that require matching with a mating item - screws or bolts with nuts or washers - have diameters that are denominated in actual inches or fractions thereof, followed by the number of threads per inch. The question then becomes how to relate the bolt torque to the bolt tensile stress. The accuracy of the tightening method, as well as the change in friction, needs to be accounted for in order not to over-tighten the fastener. EZ Calc - Bolting Calculator, Enerteq's oline tool for estimating Required Torque Values. In order to evaluate the load cases, the loads for flange, bolts, gasket and loose flange are determined. PCC-1-2013 assembles current industry best practice into one easily-referenced location. 3 -2014, Process Piping Code". 5 - Flanges and Bolt Dimensions Class 150 to 2500 - Diameters and bolt circles for standard ASME B16. Below is a list of the recommended tightening torques for 12. Finally apply the 100% bolt torque value to each bolt in a clockwise direction. 4401 Application: Pressure Vessel Hinge Lay-Out: Hinge Plate & Safety Bolt. If there are five threads gaps in a 1-inch length, the thread pitch is. Therefore, the maximum fo rce that can be applied to a Belleville mainly depends on the limitations of the bolt or joint designs. A second bolt dimension that must be considered is diameter. Finally apply the 100% bolt torque value to each bolt in a clockwise direction. TABLE #1 : Bolt Tightening Sequence 9 v. BOLT SPECIFICATIONS For Standard ANSI Flanges Flange Designation Bolt Qty. 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. 20" if using a lubricant with a different K factor. When most people "guess" what friction factor (K) to use in the "short" torque equation when they try to relate bolt load to torque, they run a gauntlet of myriad unknown variables that will affect the accuracy of the assumption. In general terms, thread stripping of both the internal and external threads must be avoided if a reliable design is to be achieved. With this equation, if you know K, F and D, you can multiply them to get the torque needed to tighten the bolt so that it has the right amount of tension. Using 24 this value, the required total bolt area is calculated to be 6. BoltUp is Hydratight's simple to use web based calculator, built upon the Informate calculation engine, providing reliable, repeatable bolt loads.

A second bolt dimension that must be considered is diameter. 10, hot dip galvenized =. In the calculations, the uniform distribution nodes 1 8 are selected from the outside edge of bolt and node A is the intersection point between the contact surface and the axis of bolt. I am thinking that an extension this long will twist some, and that will reduce the amount of torque delivered to the load. The success of flanged joints depends on applying the correct amount of gasket load and achieving uniform load around the joint. Washers are not. 63 28 84 15 88 14 68 20 67 31 92 1 4 0.
