Acme/Stub Acme Thread Torque To Yield Calculation If an excessive torque is used to generate an axial load, the connection could yield before the desired axial load has been achieved. Flange stud bolt dimensions are defined in both metric and imperials sizes with unified national coarse pitch (UNC), fine pitch (UNF), fixed pitch (UN) and iso metric thread. The formula is: Wt/Ft = 10. Where ASME flange design calculations indicate that flanges will be over stressed if a standard Class 150 spiral wound gasket is used, the LS gasket is designed to compress at significantly lower bolt load than standard Class 150 spiral wound gaskets, thereby maintaining flange stresses within allowable limits. 15 2 Simplified with dM d: MR 0.

Each torque instrument, as calibrated at the factory, is certified to meet the accuracy specified in ASME B107. By combining the torque-angle curves with a few simple calculations and a basic understanding of the. A torque wrench uses torque as a proxy for bolt tension. 1/2-13 lug bolts should be torqued between a range of 35 and 50 foot-pounds. However, the washer is normally flat by the time the bolt is fully torqued. When tightening, always use the correct sequential bolt order for the flange. bolt torque value during installation helps achieve this goal. new specifications for structural joints using ASTM A325 or A490 bolts, one based on allowable stress principles and the other on a load factor and resistance design philosophy. -3- TABLE 1 RECOMMENDED TORQUE VALUES FLANGE RATING: CLASS 150 LINE SIZE BOLT SIZE NO. AN bolts come in three head styles—hex head, clevis, and eyebolt. It is a function of the materials' frictional characteristics, which are based on surface finish, coatings and so on. Determination of bolt torque for flanged connections C ontrolling the load is probably the most important criteria, together with suitable gasket selection for the application, to ensure a gas keted joint will seal properly. Hex Head Bolts: Titanium hex bolts are similar to hex head cap screws but without the added washer face. Bolts are actually a real rabbit hole of a topic , read up about bolt pre-load and why its important in piping design, if you lose tensile force on the bolt due then you lose containment of the fluid, so its important to ensure you have proper amount of bolt pre-load / bolt.

The torque chart is for reference only and assumes properly lubricated ASTM A193 B7 stud bolts with ASTM A194 2H steel nuts. In this particular context, where torque is known, the thread pitch doesn't come into it as you are calculating based on. In general, relatively larger tightening torque is required for a flat face flange with a full face gasket compared to the flange with a ring gasket when we calculate the required tightening torque based on the latest Non-mandatory Japanese Industrial Standard (JIS) evaluation method, "JIS B 2205-1991, Basis for calculation of pipe flanges"[1]. 8 Gas Pipeline Fluid Volume And Mass Calculators. ) suggested tightening torque (ft. This is due mainly to the stress concentration effect of the U-bolt bend itself, the dynamic loading that the spring transmits to the U-bolt and the difficulty of acheiving even stress on both legs of a U-bolt. bolt tension (lbs. Garlock Bolt Torque Values for. the breakout torque seen at the bolt head or at the nut of the fastener. The calculation is based on data, procedures, algorithms and data from specialized literature and standards AGMA, ISO, DIN and BS. 12; Nut factor K = 0. readout shows you your torque setting, and then changes to the follow up angle you desire. IFI-100 does not govern lock nuts above 1". Minimum three (3) inputs are required then select "Find" button to get unknown. 25-28 bolt requires 55 inch-pounds of torque. With regard to the strength categories in the above Table, ASME has assigned these categories based on the minimum yield strength of the bolt specification.

They are an economic solution to high clamping force applications with ease access. 12 Bolt Sequencing Chart. One of the dimension standards for flange stud bolts is ANSI/ASME B16. The Belleville will be in its flat position when the preload in the bolt equals the flat-load1 Since the spring will be clamped between the flat joint an d the nut, any additional torque applied to the nut will only stretch the bolt. SQUARE DRIVE TORQUE CHART. Rivera-Rosario To calculate an accurate torque, an experimental value is needed called Torque coefficient—Torque coefficient between bolt and receptacle. Add up the weight of the objects you’ll be hanging on the torque wrench (for example, total weight = 46 lb. 15 • Target torque calculation according to ASME PCC-1 Appendix J. If the preload is achieved by torquing the bolt to initial torque-yield, the maximum and minimum preloads must be determined from an application specific test. ASME Model Operating (Stress) 0. 1: UNC - UN Course thread, common for up to 1", where bolt diameter size increases with decreasing thread pitch. There are many causes of misalignment e.
