Blind flanges have the face thickness of a flange, a matching face type, and similar bolting pattern. Blind flanges can also be used to seal a nozzle opening on a pressure vessel. Because it is bolted, the blind flange provides easy access to the interior of a vessel or pipe, unlike a cap that is welded.
A reducing flange is a type of flange that usually has one size flange connection that is different from the bore (e.g., 12″ flange X 10″ bore). Fig. 16.95 shows a reducing flange. As an example, a mixer in 12″ size has been purchased instead of a 10″ that should be connected to a 10″ line.
A blind flange is a closure plate flange that terminates the end of a piping system. It can be used in combination with all of the previous flanges at all sizes and all pressure classes. It comes in the following facings: raised faced (low-, medium-, and high-pressure classes), flat faced (low-pressure class), and ring-type joint (low-, medium-, high-, and very high-pressure classes).
The orifice flange is a single component of the orifice flange union assembly (Figure 4.26). The orifice flange union is composed of two orifice flanges, an orifice plate, bolts, nuts, jack screws, and two gaskets. A representation of an unbolted and separated orifice flange union assembly is depicted in Figure 4.27.
2023年8月1日 · In symmetric flange joint, the relaxation in flange ring contributes about 30% of the total relaxation; whereas the contribution from cover plate (blind flange) is 6% of total relaxation. The creep behaviour is analytically modelled by coupling the axial deformation and compatible condition.

2023年2月1日 · As discussed earlier, failure of specimens started from the bending yield of the T-stub flange in the test, and blind bolts guaranteed the same strong force transmission as through bolts. There were no damages to the tensile bolts in the test, and FE simulation showed that the compressed T -stub behaved well when the tensile stub met the design requirements.
According to ANSI standards, each flange is stamped with identifying marks. Different types of ANSI flanges include: weldneck flange, slip-on and Lap joint flange, threaded flange, socket weld flange, reducing flange, and blind flange. Material control of flanges include, its receiving, applying commodity code number, storage, and their shipping.
2017年5月1日 · Mechanism of prying action. The T-shape connection, whose cross-section shape is identical to that of the circular pipe flexible flange, is a good calculation model to describe the mechanical behavior of prying action. Comparing the relative stiffness between the bolts and plate, the failure mode of T-shape connections can be divided into three ...
