Q235 carbon steel pipe cap

Pipe cap, also known as head, plug, cap, pipe cover, or blind head. Q235 carbon steel pipe cap is a pipe fitting welded at the pipe end or installed outside the pipe end to cover the pipe. Used to seal pipelines, with the same function as pipe sealing heads. Used for various container equipment, such as storage tanks, heat exchangers, towers, reactors, boilers, and separation equipment

Pipe caps are classified according to their manufacturing materials, including carbon steel, stainless steel, alloy steel, special alloy steel, duplex stainless steel, etc; Carbon steel: (20 #, A3, Q235, Q23 excellent, 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, 00Cr17Ni14Mo2, 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.); Dual phase stainless steel: (F51, S31803, S2205, F53, 2507, S32750, F55, 2607, S32760, etc.)

Common execution standards for pipe caps

National pipeline 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, SH/T3410-2012 forged steel socket welded pipe fittings

Pressure vessel head standards: GB/T25198-2010

Pipe caps are excellent and important components in pressure vessel equipment in many industries such as petrochemicals, nuclear energy, water conservancy, food, machinery, diagnosis and treatment equipment, fertilizers, shipbuilding, etc.

. A pipe cap is an end cap on a pressure vessel and is a major pressure bearing component of the vessel. Its function is sealing. A pipe cap is used to seal the upper and lower bottoms of a tank pressure vessel or the end of a pipeline that is no longer intended to extend forward, by welding the pipe with a pipe cap. After the pipe cap is welded, it cannot be disassembled again. The quality of the pipe cap directly affects the long-term performance and good operation of the pressure vessel
