Overview

This 12-inch spiral wound gasket is engineered for high-integrity sealing in demanding industrial piping systems. Manufactured in strict compliance with the SH/T standard, it is specifically designed for use on steel pipe flanges rated for 900LB pressure classes. The gasket's construction utilizes a PTFE (polytetrafluoroethylene) chemical base, providing exceptional resistance to a wide spectrum of corrosive media. The inclusion of 304 stainless steel inner and outer rings ensures dimensional stability and prevents over-compression during flange bolt-up, making it a reliable, long-term sealing solution for critical service applications.

Key Features

Engineered to SH/T standard specifications for assured quality and fit PTFE chemical base offers superior chemical resistance and broad media compatibility Robust C2230 spiral windings construction for resilient, high-pressure sealing 304 stainless steel inner and outer rings for gasket stability and crush resistance Designed for reliable performance in high-pressure (900LB) flange connections Supports continuous operation in temperatures up to 500°F

Frequently Asked Questions

What are the key specifications and standards for this spiral wound gasket?
This gasket is manufactured to the SH/T3407-2013 standard, with a nominal pipe size (NPS) of 12 inches (DN300) and a pressure class of 900LB. It is constructed with a C2230 (304 stainless steel inner/outer ring, PTFE filler, 304 stainless steel winding) configuration, suitable for temperatures up to 500°F.
What are the typical applications and use cases for this specific gasket?
This gasket is designed for sealing flanged connections on 12-inch steel piping systems in high-pressure (900LB class) service. Its PTFE filler makes it ideal for corrosive chemical services, while the 304 stainless steel winding and outer ring provide structural integrity for demanding industrial applications.
How is this gasket packaged and ordered?
This gasket is sold as a single unit. Each gasket is individually packaged to prevent damage during shipping and handling. Please specify the exact standard (SH/T3407-2013), size (12 inch / DN300), pressure class (900LB), and material specification (C2230) when ordering to ensure you receive the correct component.
