The utility model discloses a ring compression type pipe fitting with strong oxidation resistance, which comprises a pipe body, the pipe body comprises a first substrate layer, the inner surface of the first substrate layer is provided with a high-strength stainless steel layer, the outer surface of the first substrate layer is coated with a nano ceramic coating, and the first substrate layer is made of nickel alloy materials. The first substrate layer is made of nickel alloy, the high-strength stainless steel layer arranged on the inner surface of the first substrate layer enables the pipe body to have super-strong oxidation resistance, and the nano ceramic coating coated on the outer surface of the first substrate layer enables the pipe body to have super-strong oxidation resistance. The carbon steel layers and the cast iron layers of the flanges fixedly connected to the top and the bottom of the pipe body have very good oxidation resistance, through cooperation of the structures, the purpose of high oxidat
