Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This innovative spiral wound gasket from Ningbo Dongheng Sealing Co., Ltd. is engineered with a robust solid outer and inner ring design. To boost performance, an inner ring is strategically incorporated to ensure flawless gasket functionality. This upgrade not only enhances centering on the flange face with an external guide ring but also secures the gasket's position, preventing possible implosion into the pipe during installation. It acts as a bulwark against extreme temperatures and harsh mediums, safeguarding the sealing element. Additionally, it fills the void between flanges, protecting them from erosion and significantly reducing the risk of failure. The choice of the inner ring material, typically matching the winding alloy, adheres to the strict guidelines of the DIN 2699 standard (German) and is crucial for gaskets with PTFE fillers according to ASME B16.20 standards. It is equally important for graphite fillers. This design is ideal for both raised and flat-faced flanges. The external ring further strengthens the gasket radially, acting as a compression stop to avert blowouts. Made often from carbon steel, painted or zinc-plated to resist corrosion, the outer ring can be crafted from specialized alloys for high-temperature and severe environments, demonstrating adaptability and enduring strength in challenging applications.
