A buttweld fitting is a weldable pipe fitting that can be used to alter the flow direction, branch off, reduce pipe size, or attach auxiliary equipment. Elbows, tees, reducers, crosses, caps, and stub ends are available in a variety of shapes, material grades (carbon, high-yield carbon, low-alloy, stainless, duplex, and nickel alloys), and sizes (elbows, tees, reducers, crosses, caps, and stub ends) (2 to 24 inches in seamless execution, and welded for larger pipe sizes). Buttweld fittings have several advantages, including being powerful and leak-proof, having fitting connections that reduce the pressure, having an extended service life, and also being moderately inexpensive to use. These fittings each have their characteristics, which vary depending on the material used in the fabrication process.
Here are some of the details of Buttweld Fittings types and applications you should go through.
Types of Buttweld Fittings are as follows: –
- Equal Tees
A straight tee is also recognized as an equal tee. This tee is a buttweld fitting that joins the pipeline at a 90-degree angle. The good size of an equal tee is the same at the run and the branch diameter is always the same. Buttweld Equal Tees appear in a range of sizes, ranging from half-inch to more than 48 inches. Buttweld Tees are available in two styles: seamless and welded. Buttweld tees are made by ASME B16.9, which means they’re made of carbon and other suitable alloys.
- Reducing Tees
A reducing tee has a small bore size on one side and is branched with another pipe side on the other. The level is approximately two-thirds of the size of the inlet side. Whereas massive bore size reduction is required, a branch connection is preferred to limit disturbance and maintain a consistent flow of materials. ASME buttweld reducing tees come in a multitude of standard dimensions and tolerances that comply with ASME B16.19.
- Pipe Cap
To divide or blind the pipeline, a buttweld pipe cap is used. It can be used on a long-term or short-term basis all through repairs and maintenance. Steel plates are being used to fabricate Buttweld pipe caps, which come in different sizes. Ellipsoidal-shaped pipe caps come in a wide range of sizes and are suitable for a wide range of piping applications.
- Buttweld Reducer
There are two types of Buttweld Reducer and they are: –
- Concentric Reducer: – The concentric reducer’s open ends are merged and cantered one to another. This kind of reducer is generally used to reduce the pipeline’s bore size by two or three measures. This reduces the amount of pressure in the pipeline. A series of reducers are used to progressively adjust the bore size of the pipeline for larger reductions.
- Eccentric Reducer: – Eccentric Reducers have open ends that are offset and are frequently used during pipeline applications. In the pipeline, these reducers are installed in a horizontal position.
Applications of Buttweld Fittings are as follows: –
- There are numerous advantages to using buttweld fittings in a piping system over other types.
- When a fitting is welded to a pipe, it becomes permanently leakproof.
- The system is strengthened by the continuous metal structure formed between pipes and fitting.
- A welded system saves space by having a smooth inner surface and gradual directional changes that reduce pressure losses and turbulence while also reducing corrosion and erosion.
