They are typically made from forged materials and have machined surfaces. Each specification further delineates flanges into pressure classes: However these classes do not correspond to maximum pressures in psi.
Instead, the maximum pressure depends on the material of the flange and the temperature.
Materials for flanges are usually under ASME designation: In addition, there are many "industry standard" flanges that in some circumstance may be used on ASME work.
The bolting material used for flange connection is stud bolts mated with two nut washer when required.
pipe flanges and flanged fittings This dimension needs to be consistent in order to maintain overall dimensions for fabricated spools. The committee believes that maintaining this dimension to the nearest whole millimeter provides the needed precision. Examples of those dimensions and the philosophy used to create the millimeter dimensions are: Raised faces measuring something different than 2 mm meet the requirements of the standard.
Conversion to the nearest mm reflects the intended precision of the dimension. Outside diameter of flanges converted to nearest 5 mm. Outside diameters measuring other than mm meet the requirements of the standard.
Conversion to the nearest 5 mm reflects the intended precision of the dimension. Bolt hole diameters expressed in pipe flanges and flanged fittings inches.
Inch dimension bolt holes were retained for flanges manufactured to metric dimensions. Joints subject to substantial temperature extremes of high or low and thermal fluctuations may require the same attention. In addition to the foregoing conditions, the user should recognize that PVC and CPVC undergo sufficient decrease in impact resistance at low temperatures and cannot safely sustain shock loading, sudden changes of stress or temperature pipe flanges and flanged fittings high stress concentrations.
Proper installation and use should ensure high performance and longevity of these products. BoxBrownsville, TN
