Style R spiral wound gaskets offer improved stability and sealing performance through the use of additional metal plies. Their adaptability to various flange configurations makes them suitable for diverse industrial applications where a controlled compression mechanism is desirable.
Product Standards:
We can manufacture according to various standards such as ANSI B 16.20, MSS SP-44, API 605, DIN, JIS, JPI, BS 1560, JG/T, GB/T, HG, SH, or as specified by the user. We can galvanize or paint the surface according to your needs.If the gasket is intended for use in a heat exchanger and includes ribs, please provide specific drawings.
The inner ring is typically made of the same material as the steel strip to meet the requirements of the medium and operating conditions.
The outer ring is made of the same material as the pipeline and corresponding equipment casing, with carbon steel outer rings being more economical.
For specific orders, it is essential to specify the exact material, applicable standards, nominal diameter (DN), pressure rating (PN), or provide specific dimensions:
D1: Inner ring inner diameter
D2: Inner ring outer diameter
D3: Outer ring inner diameter
D4: Outer ring outer diameter
The notation for dimensions is: D1×D2×D3×D4. The default thickness for the gasket is 4.5mm, and the thickness for the ring is 3mm.
