Kaizen Steel Industries is a leading supplier & exporter of ANSI B16.9 Buttweld 45 Degree Elbows in Mumbai, India, Made from high-quality steel specializing in Stainless Steel 45 Degree Elbows and other fittings. Our products, including the 45 Degree Mitered Elbow, are known for their excellent mechanical and physical properties. Made from high-quality stainless steel, our ASME B16.9 45 Degree Elbows offer strong corrosion resistance, durable construction, and long-lasting performance.

In addition to standard sizes, we also provide customized 45 Degree Elbows and other pipe fittings and flanges to meet our clients’ specific needs. Our supply division can offer a comprehensive range of steel flanges and fittings, along with detailed information on the weight and dimensions of 45 Degree Elbows.

Our factory follows quality checks at every production stage, ensuring that the DIN 2605 45 Degree Elbow Type 3 meets the highest quality standards. Our production range includes ASME B16.9 45 Degree Elbows in various diameters, including 1D, 1.5D, 3D, and 5D elbows, typically in SCH 80.

We use top-grade raw materials such as carbon steel, stainless steel, alloy steel, and special alloys like Monel, Inconel, Hastelloy, and Incoloy to manufacture 45 Degree Elbows.

Kaizen Steel Industries specialize in producing 45 Degree Elbows up to 48 inches in diameter, with wall thicknesses ranging from 1.5 mm to 40 mm. The thickness or schedule options for Carbon Steel 45 Degree Elbow Fittings include sizes such as 5S, S40, S60, XS, 80S, 10S, 20S, S10, S20, S80, S100, S120, S30, STD, 40S, S140, S160, XXS, and more. The dimensions for 45 Degree Elbows follow standards like ANSI B16.9, ANSI B16.28, MSS-SP-43.

Elbows are essential pipe fittings that connect two lengths of pipes to change the direction of flow. They are typically available in three main angles: 90°, 45°, and 180°. Our 45 Degree Pipe Elbows, commonly known as bends, are generally made as Long Radius (LR) elbows. The 45 Degree Long Radius Elbow offers less frictional resistance to fluid compared to shorter elbows, making them more efficient in fluid flow applications.
