**Lap Joint Stub Ends** are unique pipe fittings that work hand-in-hand with **lap joint flanges**, making it a breeze to assemble and disassemble pipelines. They’re crafted to create a leak-proof seal while allowing the flange to rotate freely, which really simplifies alignment during installation. This is particularly handy in setups that need regular inspection, cleaning, or maintenance. You can find Lap Joint Stub Ends in two main types — **Long Pattern (Type A)** and **Short Pattern (Type B)** — tailored to meet specific pressure, temperature, and space needs.
These fittings are made from a variety of materials, including carbon steel, stainless steel, alloy steel, and nickel alloys, ensuring they boast impressive corrosion resistance, strength, and durability. Each fitting consists of two parts: the **stub end**, which is welded onto the pipe, and the **backing flange**, which stays loose to allow for flexible bolt hole alignment and to reduce stress during installation.
