Full Description

Application context, construction notes, and selection details for evaluating fit before purchase or repeat ordering.

Overview

This D-shaped, stainless steel flange gasket is engineered for high-integrity sealing in demanding industrial piping and pressure vessel applications. It is specifically constructed to create a reliable, leak-proof seal between flanged connections, preventing fluid or gas loss in systems operating under significant pressure and temperature. Manufactured to precise industry standards, this gasket is a critical component for maintenance, repair, and assembly operations across various process industries.

Key Features

D-shaped design with inner and outer metal rings for superior alignment and compression control. Constructed with a 304 stainless steel inner ring, outer ring, and winding for excellent corrosion resistance. Flexible graphite filler provides a tight seal and accommodates minor flange surface irregularities. Rated for high-pressure applications, suitable for systems up to 362.5 PSI. Pre-formed shape ensures correct installation and prevents misplacement on the flange face. Bulk packaging supports efficient inventory management and reduces per-unit cost.

Specifications

Material: 304 Stainless Steel with Graphite Filler Size: 0.79 inch Nominal Bore Standards: Manufactured to Industry Standards (HG/T20610-2009) Connection Type: Flange Gasket Pressure Rating: PN25 (Approximately 362.5 PSI) Configuration: D-Type with Inner and Outer Rings (D2222) Pack Quantity: 50 units

Applications

Sealing connections in chemical and petrochemical processing pipelines. High-pressure steam lines and boiler feed systems. Refinery and oil & gas production flange assemblies. Heat exchangers, pumps, and valve manifolds. General industrial plant maintenance where robust, standardized sealing solutions are required.

Frequently Asked Questions

What are the exact dimensions and pressure rating for this D-shaped flange gasket?
This is a DN20 (approximately 0.79 inch nominal bore) gasket designed for PN25 flanges, which corresponds to a pressure rating of approximately 362.5 PSI at 100°F. The D2222 designation indicates a D-shaped, metal-wound construction with inner and outer retaining rings, made from 304 stainless steel with a graphite filler.
What are the typical applications for this specific type of gasket?
This gasket is engineered for sealing standard ASME/ANSI Class 150 flanges in high-temperature and high-pressure services, such as in chemical, petrochemical, and power generation piping systems. The D-shape with retaining rings ensures precise alignment and prevents blow-out in demanding applications involving thermal cycling.
How is this item packaged, and what is the minimum order quantity?
This gasket is packaged and sold in boxes of 50 units. The packaging is designed to protect the metal winding and graphite sealing surface from damage during shipping and storage.
