304 stainless steel tube cap is a type of stainless steel tube cap. The pipe cap is the final cover of the pressure vessel, which is an important part of the pressure vessel and plays a sealing role.
304 stainless steel pipe cap is also known as head, plug, cap, pipe cover, stuffed head. A cap is a fitting welded to the end of a pipe or mounted outside the end of a pipe to cover a pipe. It is used to close pipes and has the same effect as pipe clogging heads. It is used in various vessel equipment such as storage tanks, heat exchangers, towers, reactors, boilers and separation equipment.
The cap is divided into carbon steel, stainless steel, alloy steel, special alloy steel, duplex stainless steel, etc. depending on the manufacturing material; Carbon steel: (20#, A3, Q235, Q235A, Q235B, 20G, 16Mn, Q345, Q345R, ASTM A234WPB, ASTM A105, etc.); Stainless steel: (304, 304L, 316, 316L, S30408, S30403, S31608, S31603, SUS304, ASTM A403, TP321, TP317L, 347, 0Cr18Ni9, 00Cr19Ni10, , 1Cr18Ni9Ti, 06Cr17Ni12Mo2 , 022Cr17Ni12Mo2, etc.); Alloy steel: (16MnR, Cr5Mo, 12Cr1MoV, 10CrMo910, 15CrMo, 12Cr2Mo1, A335P22, St45.8/III., A10bB, etc.); Special alloy steel: (TP310S, 904L, Incoloy800, Incoloy825, Incoloy600, Incoloy625, etc.); Duplex stainless steel: (F51, S31803, S2205, F53, 2507, S32750, F55, 2607, S32760, etc.).

304 stainless steel pipe cap is an indispensable and important part of pressure vessel equipment in many industries, such as petrochemical, nuclear, water conservancy, food, machinery, medical equipment, fertilizer, shipbuilding, etc. The lid is the final cover of the pressure vessel and is an important part of the pressure vessel it supports. The role played is sealing. The pipe cap is the top and bottom bottom of the tank pressure vessel or the pipe is at the end, and is not ready to extend forward, then use a pipe cap to seal the pipe in the form of welding. The lid cannot be disassembled after welding, and the quality of the lid is directly related to the long-term safe and reliable operation of the pressure vessel.
