Key Features & Advantages:

• Spiral Wound Gaskets using mica film as filler material
• Minimizes the deterioration of strength due to heating.
• The basic-shape gasket is used for male-female and tongue and groove flanges, bonnets of valves, as well as covers for pressure vassels, towers, and tanks. It only requires a narrow width, and safe for use under high pressure.

Typical Plant Applications:

For H.T.S.（Oxidizer: The mixture of Sodium nitrate, Potassium nitrate, and Sodium nitrite） used as high temperature Heat transfer oil

Key Features & Advantages:

• Spiral Wound Gaskets using mica film as filler material
• Minimizes the deterioration of strength due to heating.
• The circumferance of the outer ring of a gasket with an outer ring inscribes the bolt of the flange, making gasket centering easy. This ring is also useful as a guide for adjusting the amount of reinforcement and tightening of the gasket.
• This product is for use in high temperatures. Basically, No. M596 (with inner and outer rings) is recommended.
• Please use a product with inner and outer rings if the pressure rating of the flange is Class 900 (JIS 63K) or greater, or if the nominal diameter of the flange is 650A (26B) or greater.

Key Features & Advantages:

• Spiral Wound Gaskets using mica film as filler material
• Minimizes the deterioration of strength due to heating.
• A gasket with an inner ring is used for a male-female flange. The inner ring not only reinforces the gasket but also decreases the clearance between the pipe's inner diameter and the gasket, as well as preventing accumulation of fluids and errosion of corner areas.
• Please use a product with inner and outer rings if the pressure rating of the flange is Class 900 (JIS 63K) or greater, or if the nominal diameter of the flange is 650A (26B) or greater.

• The outer ring of the gasket with an outer and inner rings is useful as a guide for adjusting the amount of reinforcement and tightening of the gasket, making gasket centering easy.
• In addition, use of an inner ring prevents the inner diameter side of this gasket from deformation even if the gasket is tightened too much. For this reason, gaskets with inner and outer rings are the most reliable high-temperature/high-pressure gaskets that can be mounted on raised face flanges.
