Component Specifications

Definition
Reinforcement pads are engineered metal plates or rings welded or bolted to manifold headers at critical junctions, branches, or nozzle connections to compensate for material removal and reinforce against internal pressure, thermal stresses, and mechanical loads. They enhance structural integrity, prevent fatigue cracking, and extend service life in industrial fluid handling systems.
Working Principle
Reinforcement pads work by redistributing localized stresses away from weakened areas, such as openings or joints, through increased cross-sectional area and optimized geometry. They absorb and dissipate forces to maintain pressure containment and prevent failure under cyclic loading conditions.
Materials
Typically carbon steel (e.g., ASTM A36, A516), stainless steel (e.g., ASTM A240 304/316), or alloy steel (e.g., ASTM A387). Thickness ranges from 6 mm to 25 mm, matching or exceeding header wall specifications.
Technical Parameters
  • Diameter 50-300 mm
  • Hole Size Matches nozzle OD
  • Thickness 6-25 mm
  • Weld Type Full penetration fillet weld
  • Surface Finish SA 2.5 blasted or mill finish
Standards
ISO 9001, ASME BPVC Section VIII, DIN 28011

Frequently Asked Questions

What is the primary function of a reinforcement pad in a manifold header?

To reinforce areas where material is removed (e.g., for nozzle attachments) by redistributing stresses and preventing failure from pressure or thermal loads.

Can reinforcement pads be used interchangeably between different manifold types?

No, they are custom-designed based on header dimensions, pressure ratings, and material compatibility to ensure proper fit and performance.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
