Support Ring / Skirt Component – Machinery and Equipment Manufacturing

Component Specifications

Definition

A structural component in inlet distributor systems that provides radial support to the distributor body, maintains alignment with connected piping, and may incorporate a skirt extension to guide fluid flow into downstream equipment while preventing turbulence and leakage.

Working Principle

Distributes mechanical loads from the distributor body to the mounting structure, ensuring stability under operational pressures and thermal expansion. The skirt portion directs fluid flow smoothly from the distributor outlet into the receiving vessel or pipe, minimizing pressure drop and preventing flow separation.

Materials

Carbon steel (ASTM A36/A516 Gr.70), stainless steel (304/316L), or alloy steel; corrosion-resistant coatings or cladding for aggressive media; operating temperature range: -50°C to 400°C.

Technical Parameters

Height 50-300 mm
Thickness 6-25 mm
Mounting Holes 8-24 bolts (M12-M24)
Outer Diameter 300-2000 mm
Surface Finish Ra ≤ 3.2 μm (flow surfaces)
Pressure Rating Up to 25 bar

Standards

ISO 9001, ASME B31.3, DIN 28011
