What is SS 304 with PTFE Filler Spiral Wound Gasket?
AISI SS 304 with PTFE filler spiral wound gasket is made of V-shape Aisi SS 304 tape and soft PTFE filler, also consists of inner and outer ring. This kind of gasket has excellent corrosion resistance and good resistance to intergranular corrosion. Of oxidizing acids, such as concentration ≤ 65% below the boiling temperature of nitric acid, with strong corrosion resistance. Most of the alkali solution and organic acids and inorganic acids also has good corrosion resistance.SS 304 stainless steel is the most common form of stainless steel used around the world due to excellent corrosion resistance and value. 304 can withstand corrosion from most oxidizing acids. That durability makes 304 easy to sanitize, and therefore ideal for kitchen and food applications.
Advantages of SS 304
1. SS 304 has excellent hot and cold forming process and performance. Can processing board, tube, wire,tape, type of product, for the manufacture of cold heading, deep drawing, deep drawing forming parts.2. It has Better low temperature performance. At -180 ℃ condition, strength, elongation, area reduction rate is very good. In the absence of brittle transition temperature, often used at low temperature.
3. SS 304 steel has good weldability. Welding method can be used often, both before welding without heat treatment after welding.
Can SS 304 with PTFE Filler Spiral Wound Gasket be Used for Flat Face Flange?
CGI type 304 with PTFE filler spiral wound gasket is suitable for use on flat-face and raised-face flanges, and can be specified for high pressure and temperature service or where corrosive or toxic media are present.
