Spreadsheet calculator that follows paragraph "Reinforcement of Welded Branch Connections". Added reinforcement is required to meet the criteria in paras. (b) and (c) when it is not inherent in the components of the branch connection.
an additional reinforcing element such as a reinforcing pad or saddle. The use of branch fittings can provide an economic alternative to tee fittings, reinforcing pads or saddles. Branch fittings are attached to the run pipe by welding. A branch fitting''s strength and corresponding thickness is specified by the wall schedule of the
(3) If there is a non standard connection usually what we fabricate on site like pipe to pipe branch connection, it need a calculation of strength as per Para which will tell of the additional requirement of reinforcing pad and if strength of branch fulfils the criteria of code.
The calculation for Reinforcement of Welded Branch Connections has been carried out based on ASME paragraph This Branching Table has been calculated for HeadertoBranch Angle of 90° Beta Angle only. Calculated Available Area is inclusive of the Area Available in the fillet weld of minimum size, as defined in ASME paragraph
To avoid this, an additional reinforcement pad is welded to the pipe, this type of branch connection is fabricated at the site. In the second method, instead of an additional reinforcement pad, you used a heavier specially designed branch that works as a Selfreinforced branch. This Specially design branch connection is known as "Olets."
ASME Process Piping Branch Reinforcement Calculator Module . Calculate ASME process piping required branch reinforcement for welded and extruded branches. The calculations are valid for right angle welded branches, angled welded branches ≥ 45 .

May 30, 2014· Good morning, i m calculating reinforcing pad (added reinforcing area A4 as per ASME appendix H example 2) but i have not find any formula for it.(in ring and in fillet welds) also in this example tc/=/ = define "tc". In they are refering (f) after that refering to which also refers to and i have not find any formula for it.
Jul 02, 2010· Note: Reinforcing can be provided by the run and branch pipe themselves if they have additional thickness over that required for pressure containment and other allowances. Example: An unreinforced "stubin" connection can be acceptable when the design pressure of the system is very low relative to the theoretical allowance design pressure of the piping used .
design calculations is permitted for weld reinforcement. Groove weld sizes for welds in T, Y, and Kconnections in tubular members are shown in Table Fillet Welds Effective Throat Calculation. The effective throat shall be the shortest distance from the joint root to the weld face of the diagrammatic weld (see Annex I).

Mar 05, 2011· As per ASME B (2004 edition), section Reinforcement of Welded Branch Connections, the diagram for RF Pad thickness calculation has shown notations like t b, t h,T b,T h, C, Mill tolerance etc.. Now T b or T h refers to the t min which is the minimum pipe thickness of branch and header respectively which is required.
Oct 17, 2019· Any pipe having an opening, for branch connection will be weaken, if pipe wall thickness will not sustain the pressure. In this case, pipe reinforcement is necessary to provide. The amount of reinforcement required to sustain the pressure, shall be determined in accordance with reinforcement Calculation for Welded Branch Connections as per ASME B, which is covered comprehensively .
Area resulting from excess thickness in the branch pipe wall, mm 2. A 3: Area provided by deposited weld metal beyond the outside diameter of the run branch, mm 2. A 4: Area provided by a reinforcing ring, pad or integral reinforcement, mm 2. A 5: Area provided by a saddle on right angle connection, mm 2. D r: Outside diameter of ...

In they are refering (f) after that refering to which also refers to and i have not find any .
Jul 27, 2015· Pipe branch reinforcement calculations per ASME B31. The user can choose pipe materials, flange rating and material, pipe dimensions, factors, and branch .
The pad must be positioned so that around the branch, is overall the same open space, and that the pad is fully in line with the run pipe. Tack weld the pad on a sufficient number of places, and after that the pad can be inside and outside fully welded; depending on the prescribed quality requirements, then again NDE must be done.

A. Keith e, in Pressure Vessel and Stacks Field Repair Manual, 2008. Lifting lugs are connected to the shell with fillet welds. If lifting lugs are welded to a reinforcing pad, and the pad is connected to the shell with fillet welds, then the capacity of the lifting lugs is a function of the strength of the pad fillet welds, as well as the fillet welds attaching the lug to the pad.
