Welded Connection - an overview ScienceDirect Topics

Threaded couplings are the easiest and quickest method of connecting pipe (Figure 4.1).However,there are a number of disadvantages.Threaded couplings are difficult to maintain a leak-proof connection,due to interference fit,in sizes greater than 3 in.(76.2 mm).There is an effective reduction in wall thickness when the threads are cut.US Bolts - Tensile Strength and Proof LoadsRelated Topics .Fasteners - Bolts,nuts and threaded rods - torque,tension and loads; Related Documents .ASME/ANSI B16.5 - Flanges and Bolt Dimensions Class 150 to 2500 - Diameters and bolt circles for standard ASME B16.5 flanges - 1/4 to 24 inches - Class 150 to 2500 ; Bolt Stretching and Tensile Stress - Tensile stress and Hooke's Law; Bolt Torque Calculator - Calculate required bolt torqueUS Bolts - Tensile Strength and Proof LoadsRelated Topics .Fasteners - Bolts,nuts and threaded rods - torque,tension and loads; Related Documents .ASME/ANSI B16.5 - Flanges and Bolt Dimensions Class 150 to 2500 - Diameters and bolt circles for standard ASME B16.5 flanges - 1/4 to 24 inches - Class 150 to 2500 ; Bolt Stretching and Tensile Stress - Tensile stress and Hooke's Law; Bolt Torque Calculator - Calculate required bolt torque

Table of material properties for structural steel S235

Nominal values of structural steel yield strength and ultimate strength.For structural design according to Eurocode 3 (EN1993-1-1),the nominal values of the yield strength f y and the ultimate strength f u for structural steel are obtained as a simplification from EN1993-1-1Stud Bolts McMaster-CarrGrade B16 threaded rods maintain their strength at higher temperatures than Grade B7 threaded rods.They meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks,valves,and flanges.Structural Steels S235,S275,S355,S420 and Their PropertiesThis is because exceeding tensile strength means failure,while exceeding yield strength only ends in a deformation.The properties table shows that increasing grades mean higher strength.S235 and S355 steels are the most popular among those presented here,as they cover most needs.S275 does not find much use and may be harder to find.
