Pad for Pipe Reinforcement
To strengthen high-stress locations, guard against damage from external loads, and maintain structural integrity, a pipe reinforcing pad, also known as a repad, is a metal plate, often composed of carbon or stainless steel, that is welded around a pipe branch junction. They distribute stress away from cutouts by acting as a saddle, especially in systems with high temperatures or pressures.

A PetroSan pipe reinforcement pad, also known as a reinforcing pad or pipe saddle, is a metal plate or pad welded onto a pipe to provide additional support and reinforcement around a branch connection or nozzle.
Key purposes:
– Distribute stress concentrations
– Reduce pipe wall stress
– Prevent pipe deformation
– Increase connection strength
Commonly used in:
– High-pressure piping systems
– Large-diameter pipes
– Critical connections (e.g., headers, manifolds)
– Areas with high vibration or stress.
Pipe reinforcing pad specifications typically include:
– Material: matching pipe material (e.g., carbon steel, stainless steel)
– Size: based on pipe diameter and branch size
– Thickness: calculated based on design pressure and stress
– Shape: rectangular, circular, or custom
– Wedge angle: typically 45° or 90°
– Welding: full-penetration welds, often with specific weld procedures
– Dimensions: governed by codes (e.g., ASME B31.3, API 650)
Common standards:
– ASME B31.1 (Power Piping)
– ASME B31.3 (Process Piping)
– API 650 (Welded Tanks)
Common materials for pipe reinforcing pads include:
– Carbon steel: ASTM A516 grade 60 /70, A105, A234 WPB, A106 etc.
– Stainless steel: ASTM A240 (304, 316, 321, etc.)
– Alloy steel: ASTM A182 (F11, F22, etc.)
– Duplex stainless steel: ASTM A240 (2205, 2507, etc.)
Material selection depends on:
– Pipe material
– Service media (corrosive, erosive, etc.)
– Temperature
– Pressure
– Industry standards (ASME, API, etc.)
Installing a pipe reinforcing pad involves:
1. Preparation: clean and prepare the pipe surface
2. Marking: mark the pad location and branch connection
3. Cutting: cut the pad to size (if not pre-fabricated)
4. Welding: weld the pad to the pipe (full-penetration welds)
5. Inspection: check weld quality and pad fit
6. Testing: hydro-test or NDT (as required)
Key considerations:
– Follow welding procedures and codes (e.g., ASME B31.3)
– Ensure proper fit-up and alignment
– Use compatible materials and welding techniques
