The stud end and pipe cap look similar sometimes. Both of them are two common fittings used at the end of industrial steel pipes. In some cases, they are regarded as one thing, and most of the time they can replace each other, that has the same function with them is the blind flange. If there are no special operation on the pipeline, then pipe cap or plug directly welded to the pipeline, if considering the future pipeline transformation or disassembly convenience requirements, then the blind flange will play a role.
Steel Pipe Cap, a pipe fitting welded to a pipe end or mounted on the external thread to seal a pipe, acting as a pipe plug. Ranges from connection types, the steel cap can be divided: butt weld cap, socket weld cap, threaded cap. The stud head is used for blocking the internal thread of the pipe end or the external thread of the flange. There are square tube plug, hexagonal tube plug, round plug.
Both Stub and cap are made by the same material and used for same applications. They are widely used in the petroleum, chemical, power, gas, metallurgy, shipbuilding and construction industries and they are made from high quality raw materials like carbon steel, alloy steel, stainless steel and available in a variety of sizes and designs according to ASME/ANSI B16.9.
