Pipe Branch reinforcement pad strength calculation- (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 304.3.3 which will tell of the additional requirement of reinforcing pad and if strength of branch fulfils the criteria of code.

What is a Reinforcement PAD? Reinforcing Pad or RePAD or RF Pad (Fig. 1) is a donut-shaped pad that goes around the branch of a branch joint to add strength to the joint. It resembles a round metal washer that has been bent to conform to the curvature of the pipe. Why is the reinforcement pad required? RePADs or RF

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.

14-10-2012· nominal thickness of branch. d 1: effective length removed from pipe at branch, mm. d 2 "half width" of reinforcement zone, mm. L 4: height of reinforcement zone outside of run pipe, mm. T b: branch pipe thickness, mm. T h: run pipe thickness, mm. t r: minimum thickness of reinforcing pad, mm. t mh: pressure design thickness of run pipe, mm. t mb

02-07-2010· 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 “stub-in” 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 (e.g., low-pressure ASME 150 ...

05-03-2011· As per ASME B 31.3 (2004 edition), section 304.3.3 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.

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 run and branch pipes. Very often the designer may require the use of a branch fitting to provide reinforcement for external loads other than

The need for the provision of a reinforcing pad around such opening is ascertained and the pad thickness is arrived at using the area compensation method stipulated by the codes. In this article, we will explore the Nozzle reinforcement pad calculation methodology for a cylindrical Nozzle provided on any shape of a vessel or a closure.

Pad Width: the width of the sides of the pad as measured from the hole cutline (either interior or exterior ) which is the furthest out from the branch.The measurement is done when the pad is flat, so if Material is not specified as 'Flat', the width of the template will be larger than the specified distance to compensate for the bending opperation.
