Torque is the turning force measured in foot-pounds (ft-lb) or inch-pounds (in-lb) applied to tighten (turn) the nut on a bolt. Torque values assume that Nickel Anti-Sieze thread lubricant is used. The nut factor is not the coefficient of friction. K – constant d – diameter of bolt (m, in) F – axial bolt force or load (N, lb) Support keyboard_arrow_right Bolt Torque Calculator. It is important to ensure that the gasket material is selected accordingly. Cheers. 1 The maximum recommended gasket stress on Multi-Swell™ 3760 is 10,000psi. either that for gasket seating or for external loading, whichever is the greater. They are of two types, metric flange bolts and metric hex bolts. It is a function of the materials' frictional characteristics, which are based on surface finish, coatings and so on. To those who made an effort to reply, I really appreciate your contribution. Torque can be measured during flange assembly with a properly calibrated torque wrench. In a bolted flange, the applied torque generates the axial load in the bolt. Bolts that are fully or partially threaded, with washers and nuts are called as metric bolts. Bolt torque calculations keyword after analyzing the system lists the list of keywords related and the list of websites with related content, in addition you can see which keywords most interested customers on the this website. Garlock Bolt Torque Values for .031" thick Compressed Sheet1 & GYLON® Ring Gaskets - ANSI B16.5 Class 150# Flanges. Table is for standard pipe flanges only. either that for gasket seating or for external loading, whichever is the greater. Bolt Torque. Metric .

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 .The big problem is that the load on the gasket cannot be measured directly and easily during installation. If bolts are to be torqued "dry", increase wrench setting by 20%.

Simply input your nominal pipe size and the calculator will provide a bolt torque estimate and other related torque settings.
The calculator below can be used to calculate the torque required to achieve a given axial bolt force or load. Flange Bolt-Up Bolting Torque Table ... bolt, flange and nut condition; equipment calibration and condition; perpendicularity of the bolt, nut and flange; etc. Flange Bolt Size Chart and Torque Patterns. Bolt Data: Size: ... K Factor is a torque coefficient between bolt and receptacle. Ultimately at the end of the day, apart from the gasket seating and bolt torque calculations, I would also want to perform a flange leakage calculation. Bolt Torque Calculator. ASTM A490 covers heavy hex structural bolts from 1/2 inch diameter through 1-1/2 inches diameter and are made of alloy steel. The bolt acts like a spring. A flanged PE pipe joint is an engineered assembly consisting of several components, likely to have been manufactured by a variety of companies and from varying plastic and non-plastic materials.

Flange bolt loading will constitute the highest requirement, i.e. Flanged joints are commonly used to connect polyethylene (PE) pipelines to valves, pumps and pipes of different material. Metric Bolt Torque Calculator. 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. The values in the tables are based on the equation: T = Torque value, (ft-lbs) F = Bolt pre-load, (lbs) k = Nut Factor based on lubricant used d = Nominal bolt diameter, (in.)
