The forged socket cover is the final cover of the pressure vessel, which is an important part of the pressure vessel and plays a sealing role. 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.
Tube caps are also known as headers, plugs, hoods, pipe covers, and stuffed headers. Forged socket caps are fittings welded or mounted outside the end of the tube to cover the tube. 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.).
A commonly used executive standard for tube caps
National standard pipe standards: GB/T12459-2017, GB/T13401-2017
Petrochemical standards: SH/T3408-2012 steel butt welded seamless pipe fittings, SH/T3409-1996 steel plate butt welded pipe fittings, forged steel socket welded pipe fittings SH/T3410-2012
Pressure vessel head standard: GB/T25198-2010
Pipe caps are indispensable and important components in pressure vessel equipment in many industries, such as petrochemical, nuclear energy, 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.
