Pipe Elbows

Pipe Elbows

Pipe elbows are essential pipe fittings used to change the flow direction in piping systems. Available in various bend angles such as 90°, 45°, and 180°, these elbows come in both long radius (LR) and short radius (SR) designs to suit different installation needs. Whether used in plumbing, oil & gas, chemical, or industrial systems, elbows help maintain efficient flow paths and system flexibility in tight or complex layouts.

Types and Sizes:

The range includes:

• 90° Long & Short Radius Elbows

• 45° Long & Short Radius Elbows

• 180° Long & Short Radius Elbows

Seamless elbows are available in sizes from 1/2″ to 24″ (DN15–DN600), while welded elbows range from 4″ to 72″ (DN150–DN1800). These fittings are manufactured to accommodate a wide range of wall thicknesses, from SCH 5S to SCH XXS, ensuring compatibility with all major piping systems.

Standards and Specifications:

All elbows conform to key international standards including ANSI B16.9, ANSI B16.28, MSS-SP-43 Type A & B, and JIS B2312/B2313. These standards guarantee consistency in dimensions, wall thickness, pressure rating, and overall performance, making the elbows suitable for both standard and high-demand applications.

Materials and Surface Finish:

Available in both carbon steel (e.g., ASTM A234 WPB) and stainless steel (e.g., ASTM A403 WP304, WP316), these elbows cater to a variety of environmental and pressure requirements. Stainless steel grades like 304, 304L, 316, 316L offer excellent corrosion resistance. Surface treatments include anti-rust oil, black lacquer, yellow lacquer, clear lacquer, and hot-dip galvanizing for extended durability in corrosive conditions.

Applications and Advantages:

Elbows are widely used in plumbing, HVAC, petrochemical, power generation, and marine piping systems. Their main advantage lies in their ability to change pipe direction smoothly, reduce flow pressure losses, and support compact installation configurations. Whether it’s a high-pressure steam line or a low-pressure drainage system, these elbows provide leak-proof, long-lasting performance.
