Introduction to Stub Ends
Stub ends, also known as lap joint flanges, are pipe fittings that are used in conjunction with a lap joint flange. They are a type of pipe fitting that is designed to be welded onto the end of a pipe. The main advantage of stub ends is that they allow for easy alignment and disassembly of the piping system. They are commonly used in applications where frequent maintenance or inspection is required, such as in the oil and gas, chemical, and power industries. Stub ends are available in various materials, including carbon steel, stainless steel, alloy steel, and nickel alloys, to meet the different requirements of different industries.
