EEMUA 145 Weld Neck Stub End Basic Info

Section 3.4 gives details of the 90/10 copper nickel weld neck stub ends, whereas Section 3.5 gives details of the forged carbon steel plate-type backing flanges.

The range of sizes covered for these composite weld-neck flanges are ½ in/16 mm – 36 in/914 mm*4 , normally, the size is from dn 15 to dn 500 on shipment.

Two types of copper nickel stub ends are included in Section 3.4.

The short components (type S) are based on DIN 86037 but modified to suit the appropriate tube wall dimensions.

The long components (type L) are based on MSS SP-43:2013(24) to suit the appropriate tube wall dimensions. The long stub ends have been included to facilitate the attachment of this type of flange to butt welding elbows, tees, and the small end of reducers.

Only one type of backing flange is included in Section 3.5. The same backing flange is required for all weld neck stub ends whether they be long or short, 16 bar or 20 bar. This type of backing flange is not suitable for use with composite slip-on stub ends.

The thicknesses of the plate type backing flanges have been determined to meet the requirements of the ASME Boiler and Pressure Vessel Code, Section VIII, Division 1, Appendix 2, except that design stresses have been established in accordance with ASME B31.3-2014 criteria.

The following design criteria have been used:

(a) Drilling and outside diameter dimensions of flange sizes ½ inch/16 mm – 24 in/610 mm are in accordance with ASME B16.5-2013 and BS EN 1759-1:2004,

whereas the larger sizes, 28 in/711 mm – 36 in/914 mm are in accordance with MSS SP-44-2006.

(b) All calculations for backing flanges have been carried out using a design pressure of 20 bar at 38°C.

(c) Carbon Steel Backing flanges: ASTM A105-14(25) forged carbon steel. (d) Gaskets: 1.5 mm thick. (e) Bolting: ASTM A193-B7(26).

Design stresses used in the calculations were as follows:

  • Steel backing flanges: 160.7 N/mm2.
  • B7 bolting: 172.4 N/mm2.

Based on the results of the above calculations an attempt has been made to rationalize ½ in/16 mm up to and including 1½ in/44.5 mm backing flanges which utilize the same bolting. The opportunity was taken therefore to use the same flange thickness (dimension ‘b’) determined for the largest of this size range and apply it to the smaller sizes, resulting in identical bolt lengths for all flanges in that range. This was considered to be a practical and economical advantage within the industry.

The dimensions of backing flanges are governed by the strength required to resist the bolting forces which may occur on bolting up. Therefore all backing flanges are suitable for a maximum working pressure of 20 bars at 38°C.

This Specification does not specify hydraulic test pressures for flanges or components, details of which should be obtained from the appropriate application standards.

 

3.2 Pressure/Temperature Ratings

Pressure/temperature ratings are the maximum allowable working pressures (MAWP) at the temperatures shown in Appendix B. If a stub end rated at 16 bar is required to be connected to a stub end rated at 20 bar then that flanged joint shall be rated at 16 bar (see Tables 12 and 13).

The temperature shown for a corresponding pressure rating is considered to be the same as that of the contained fluid.

3.3 Materials

3.3.1 Flanges

Stub ends detailed in Section 3.4 shall be manufactured in 90/10 Cu Ni alloy UNS 7060X,the composition and mechanical properties of which are specified in Table 17. Backing flanges detailed in Section 3.4 shall be manufactured from the material specified in Table 18. Alternative steels may be used for the backing flanges provided that they have mechanical properties equal to or better than those specified in ASTM A105-14 (normalized) and are acceptable to the Purchaser.

3.3.2 Gaskets

The gaskets shall not be graphited. Alternatively neoprene type gaskets with a minimum Shore hardness of not less than 75 may be used located within the bolt circle.

Note: Gaskets should not be used when mating with elastomer/rubber faced flanges.

3.3.3 Bolting (Stud Bolts)

Bolting for flanges to this Specification shall be selected from ASTM A193-B7 and ASTM A194-2H(27) and should be suitably protected from corrosion.
