Jayshree Industrial Corporation is a prominent manufacturer and supplier of buttweld pipe fittings based in Ahmedabad, Gujarat Buttweld fittings are specialized piping components designed to be welded directly to the ends of pipes to change direction, branch off, or reduce pipe size. They are primarily used in high-pressure and high-temperature industrial systems, such as oil and gas or chemical processing. Common Types of Buttweld Fittings Buttweld fittings come in various shapes and functions to meet specific piping layout needs: Elbows: Used to change the direction of fluid flow. Common angles include 90°, 45°, and 180°. They are available in Long Radius (LR), where the radius is 1.5 times the nominal pipe size, and Short Radius (SR), which is used in tight spaces. Tees: Allow for branching a pipeline at a 90° angle. Equal Tees have the same bore diameter for all three outlets, while Reducing Tees have a smaller branch size for connecting smaller pipes. Reducers: Connect pipes of different diameters. Concentric Reducers maintain a common centerline (often for vertical pipes), while Eccentric Reducers have offset ends to prevent air or liquid pooling in horizontal lines. Caps: Installed at the end of a pipe to permanently or temporarily seal the flow. Stub Ends: Used with lap joint flanges to allow for easier alignment and frequent disassembly for maintenance. Crosses: Connect four pipes at right angles. While less common due to stress concentrations, they are used in compact layouts like marine piping. Material Grades and Standards Fittings are typically manufactured from the same material as the pipe they connect to ensure weld compatibility and system integrity. Carbon Steel: Most commonly ASTM A234 WPB, used for general industrial and high-pressure applications. Stainless Steel: Grades like SS 304/304L and SS 316/316L are preferred for corrosion resistance in chemical or food processing. Alloy Steel: Grades such as ASTM A234 WP1, WP11, and WP22 are utilized for high-temperature and high-pressure services. Dimensional Standards: Most fittings are manufactured according to ASME B16.9 (long radius and general fittings) or ASME B16.28 (short radius elbows). Recommended Products The following are representative examples of industrial buttweld fittings available from specialized suppliers: Carbon Steel Butt Weld Fittings (ASTM A234 WPB) Reviewers on ibrpipefittingsandflanges.com note these are commonly used in industries for their durability and abrasion resistance. These are typically available in sizes ranging from 15 mm to 1200 mm (NPS 1/2' to 48'). SS Buttweld Fittings 316L Available through Duplex Steel & Engineering Company, these are praised for being highly rigid and robust, suitable for low-carbon corrosive environments. Often includes designs for 90° elbows, concentric reducers, and straight tees.
