Field of the Invention
[1] The present invention relates to flange stud tightening and in particular, but not necessarily entirely, to a marking tape for flange stud sequence tightening and setting guidance.
Background of the Invention
[2] Within the industry flange studs (or bolts or other types of fasteners) are required to be tightened in a particular sequence and to particular torque settings such that the resultant connection meets the requisite performance standards including pressure ratings. Failure to adhere to a proper sequence and settings may result in flange seal failure.
[3] Such tightening is usually conducted in accordance with complicated torque sequence tables (as are substantially provided by way of Table 1), which furthermore only indicate the tightening sequence. However, such process is error prone, often times requiring the user to write the stud numbers, sequence and settings on the flange using chalk and the like being an unreliable methodology for performing the correct tightening sequence.
[4] The present invention seeks to provide a solution, which will overcome or substantially ameliorate at least some of the deficiencies of the prior art, or to at least provide an alternative.
[5] It is to be understood that, if any prior art information is referred to herein, such reference does not constitute an admission that the information forms part of the com mon general knowledge in the art, in Australia or any other country.

[7] The guidance marking tape may have a width corresponding to the pressure rating of the flange.
[8] The guidance marking tape may indicate a pressure rating.
[9] The guidance marking tape may indicate a flange size.
[10] The guidance marking tape may indicate a first torque setting for a first torque sequence and a second torque setting for a second torque sequence.
[11] The guidance marking tape may comprise lines of weakness for brea k-out tabs, each tab comprising a respective one of the sequence numbers.
[12] The length of the guidance marking tape may correspond to the circumference of the flange.
[13] The guidance marking tape may comprise an adhesive backing for adhering to the outer edge.
[14] There is also provided a set of guidance marking tapes comprising at least two guidance marking tapes having differing sequence numbering for a differing numbering of studs.
[15] The at least two guidance marking tapes may have differing lengths.
[16] The at least two guidance marking tapes may have differing torque sequence settings.
[17] The at least two guidance marking tapes may be configured for differing pressure ratings.
[18] The at least two guidance marking tapes may have differing widths
[19] Other aspects of the invention are also disclosed.

It is also to be understood that the terminology employed herein is used for the purpose of describing particular embodiments only and is not intended to be limiting since the scope of the disclosure will be limited only by the claims and equivalents thereof.
[25] In describing and claiming the subject matter of the disclosure, the following terminology will be used in accordance with the definitions set out below.
[26] It must be noted that, as used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise.
[27] As used herein, the terms "com prising," "including," "containing," "characterised by," and grammatical equivalents thereof are inclusive or open-ended terms that do not exclude additional, unrecited elements or method steps.
[28] It should be noted in the following description that like or the same reference numerals in different embodiments denote the same or similar features.
[29] Turning now to figure 1, there is shown guidance marking tape 3 for flange stud sequence tightening and setting guidance. As can be seen from figure 2, the guidance marking tape 3 is configured for wrapping around the outer edge of a flange 2 so as to indicate the correct stud numbering sequence and, in embodiments, also the appropriate torque settings. [30] Returning again to figure 1, the guidance marking tape 3 comprises tightening sequence numbering 5 having a plurality of sequence numbers 5 spaced apart such that each respective sequence number corresponds to a respective stud 4 of the flange 2 from figure 2 when the guidance marking tape 3 is wrapped around the outer edge of the flange 2.
[31] Specifically, turning now to figure 2, there is shown the guidance marking tape 3 of figure 1 having been wrapped around a flange 2 wherein, as can be seen, each sequence number 5 corresponds with a respective stud.
[32] Specifically, for illustrative purposes, each stud in figure 2 has been numbered from 1 to 12, wherein the stud number 1 may be any one of the studs as an arbitrary starting point.
[33] In this regard, the correspondence sequence numbering 5 indicates the correct sequence in which the studs 4 are to be tightened. Specifically, the exemplary guidance marking tape 3 shown in figures 1 and 2 is configured for utilisation with a 12 stud flange 2 wherein, as can be appreciated from the illustrations, stud 1 is to be tightened first, then stud 7, then stud 4 and so on and so forth.
[34] As can be appreciated, such sequence numbering corresponds to the industry standard stud sequence numbering for a flange having 12 studs as is illustrated from the sequence numbering table provided in Table 1.
[35] Now, in a preferred embodiment, the guidance marking tape 3 has a length configured to match the circumference of the flange 2 or have a length exceeding the circumference of the flange 2 so as to overlap.
[36] Furthermore, as is shown in figure 2, when wrapped around the flange 2, the sequence numbering 5 is appropriately spaced apart on the tape 3 so as to collocate adjacent each respective stud 4.
[37] Furthermore, the guidance marking tape 3 may display the flange size and/or pipe rating. Specifically, as is shown in figures 1 and 2, the guidance marking tape 3 comprises a flange size indication 7 indicating the diameter of the flange 2. In this regard, the user may possess a set of guidance marking tapes 3 for a plurality of flange size and stud numbers. As such, in use, the user is able to quickly and easily inspect the flange size indication 7 and pound rating indication 8 so as to be able to select the appropriate guidance marking tape 3 for use. [38] As can be appreciated, guidance marking tapes 3 may be provided for each of the stud number types as is provided in Table 1 so as to be suited for flanges having from 4 to 80 studs, for example.
[39] In embodiments, the backside of the guidance marking tape 3 may comprise an adhesive tape form so as to allow the guidance marking tape 3 to be adhered to the outer edge of the flange 2, including in having an overlap in embodiments.
[40] In embodiments, the width of the guidance marking tape 3 may correspond substantially with the width of the flange 2 so as to allow the user to quickly ascertain should the incorrect guidance marking tape 3 be used such as where, for example, the width of the guidance marking tape 3 were to exceed the width of the flange 2.
[41] Generally, the width of the flange 2 is determined in accordance with the pressure rating of the piping. In the embodiment shown, the guidance marking tape 3 may comprise a pressure rating indication 8. As such, knowing the pressure rating of the piping, the user is able to select the appropriate guidance marking tape 3.
[42] In this regard, it should be noted that differing guidance marking tapes 3 may be utilised for flanges 2 having the same size and the same number of studs but differing pressure ratings. Specifically, differing torque values may be required for differ pressure ratings as will be described in further detail below and therefore differing guidance marking tapes 3 may be required to indicate the differing torque values required in accordance with the appropriate pressure rating.
[43] However, with regards to the width of the flange 2, the pressure rating indication 8 of the guidance marking tape 3 may correspond with the width of the guidance marking tape so that, and as alluded to above, substantial deviations in the width of the flange 2 and the width of the guidance marking tape 3 may warn the user that an inappropriate guidance marking tape 3 is been used for the desired pressure rating.
[44] In embodiments, the guidance marking tape 3 may be colour-coded to indicate the pressure rating allowing for the selection of the appropriate guidance marking tape 3 in use.
[45] Now, and as also alluded to above, in embodiment, the guidance marking tape 3 may additionally indicate torque setting values. In embodiments, the guidance marking tape 3 may indicate a plurality of torque setting values for a plurality of passes, which may comprise a first, second and final pass. [46] Specifically, as can be seen from figure 1 and 2, the guidance marking tape 3 may indicate the torque setting values 6 for three passes. As can be seen from the illustrations, the guidance marking tape 3 indicates a first torque setting value of 280 ft-lbs indicating to the user that all of the studs must be tightened to this torque setting during the first tightening sequence.
[47] Once having been tightened the user repeats the indicated sequence, this time tightening the studs to the next torque setting being 490 ft-lbs. Thereafter, the user performs a final pass in accordance with the nominated sequence to the final torque setting of 700 ft- lbs. A final full rotation may then be required in embodiments.
[48] In embodiment is the sequence numbering 5 may be raised or positioned for ease of viewing. In this regard, the guidance marking tape 3 may comprise lines of weakness 9 adjacent each sequence number 5 so as to allow for the breaking thereof and the forming of tabs which may be bent upwards to assist in the viewing of the corresponding sequence numbers 5, especially from a vantage point along the elongate axis of the piping.
