A sort of pipe fitting is an Unequal Tee. The branch connects to the main pipe with a T-shaped fitting. It is often made from a variety of materials and comes in a range of sizes. Alloy steel, copper-nickel, and carbon steel are the most popular materials used to create Unequal Tees. Unequal Tee Pipe Fittings provide one scheduled greater thickness so that sufficient wall thickness, forming after, remains. The wall thickness can be a critical item of the shape of Stainless Steel Unequal Tee Pipe Fittings. Carbon Steel Unequal Tee Pipe Fittings only standardize the end-to-end dimensions, center-to-end dimensions, and some "squareness" dimensional tolerances. Alloy Steel Unequal Tee Pipe Fittings also find application across diverse industries, owing to their compliance with industry-defined standards. Because there is no maximum tolerance for some parts of Alloy 20 Unequal Tee Pipe Fittings, the customer himself must indicate his requirements. Meanwhile, depending on a customer's specification, the manufacturer must certify that the manufactured Monel Unequal Tee Pipe Fittings is made the requested requirements. These materials differ in weldability, tensile strength, and corrosion resistance. Both high and low temperatures can be utilized with these tees. They can also be applied in cryogenic situations. Mechanically treating Buttweld Unequal Tees might increase their corrosion resistance. Sandblasting, hot-dip galvanizing, or electropolishing can all be used to obtain this.

In Nickel Alloy Unequal Tee Pipe Fittings, the crotch radius varies from manufacturer to manufacturer, but some establish themselves as a requirement. The wall thickness at the weld line location even is standardized in Inconel Unequal Tee Pipe Fittings, but not through the rest of the fitting. Hastelloy Unequal Tee Pipe Fittings states that the minimum tolerance will be within 12.5 percent of the minimum ordered wall thickness of the pipe. In Copper Nickel Unequal Tee Pipe Fittings, a maximum tolerance is specified only at the ends of the fitting. Users widely prefer Unequal Tees Butt Weld Pipe Fittings due to their accurate tensile strength, corrosion, abrasion resistance, and excellent finish.
