22-1/2 Degree Elbow, Slip x Slip PVC Schedule 40 10" (465-100)

The 465-100 is a 10" Schedule 40 PVC 22-1/2° elbow with slip socket connections on both ends. Where a 90° or 45° elbow executes an abrupt or moderate directional change, the 22-1/2° elbow provides a shallow, gradual deflection — the correct fitting when a piping run needs to offset around an obstruction, follow a slight grade change, or make a modest angular correction without the flow velocity impact and pressure loss that sharper-angle fittings introduce at large diameters.

At 10", the hydraulic and structural implications of elbow angle selection carry real engineering weight. A 90° elbow at this diameter creates significant turbulence, velocity head loss, and thrust force at the bend — all of which must be accounted for in system design and thrust restraint. The 22-1/2° elbow reduces all three: the shallow deflection angle maintains flow momentum through the bend, minimizes head loss at the directional change, and generates substantially lower unbalanced thrust forces than steeper-angle alternatives. On long-run large-diameter systems — municipal water mains, large-scale irrigation headers, and industrial distribution piping — these performance advantages compound across multiple bends throughout the system, meaningfully improving overall hydraulic efficiency and reducing thrust block requirements at each deflection point.

The 22-1/2° angle also makes this elbow the practical tool for angular corrections that fall between the capabilities of a 45° elbow and a straight run. Two 22-1/2° elbows in series produce a 45° total deflection with a longer radius transition than a single 45° fitting; combined with 11-1/4° and 45° elbows in the same series, the 22-1/2° allows system designers to achieve virtually any required deflection angle in precise, code-compliant increments across large-diameter PVC runs.

Both slip sockets accept standard IPS-dimension Schedule 40 PVC pipe bonded with heavy-bodied PVC solvent cement — the recommended grade at large diameters where socket depth, cement coverage area, and assembly time before joint movement are substantially greater than small-bore applications. Manufactured from virgin PVC compound to ASTM D2466, the 465-100 carries the white color standard for Schedule 40 fittings and is NSF/ANSI 61 listed for potable water service.

Industries & Applications:

• Municipal Water Distribution — Shallow angular corrections and obstacle offsets on 10" water transmission mains and distribution system runs; the 22-1/2° angle minimizes thrust forces at the bend, reducing thrust block size and restraint hardware requirements compared to steeper-angle fittings at this diameter
• Large-Scale Irrigation & Agriculture — Grade-following deflections and minor directional corrections on 10" irrigation supply mains, pivot system primary feed lines, and large agricultural and commercial landscape distribution headers where hydraulic efficiency across multiple bends is a system design priority
• Industrial Process Piping — Gradual directional changes on 10" process water, cooling water, and plant utility fluid distribution headers in manufacturing environments where low-pressure-loss routing around structural obstructions, equipment, and building elements is required
• Stormwater & Drainage Management — Shallow-angle directional changes on 10" gravity-flow stormwater collection and conveyance runs where maintaining flow velocity and minimizing head loss through directional transitions supports system capacity and self-cleaning performance
• Water & Wastewater Treatment — Angular corrections on 10" treatment plant distribution headers, pump discharge piping, and process water runs where gradual deflections reduce turbulence and velocity head loss at directional changes on primary flow lines
• Pump Station & Equipment Connections — Shallow-angle routing corrections on 10" pump discharge and suction headers where gradual directional changes reduce flow turbulence near pump inlets and outlets and minimize unbalanced thrust forces on connected equipment
• Fire Suppression & Site Utility — Underground directional corrections on 10" fire protection supply mains and site utility runs where shallow-angle elbow combinations allow precise angular routing in space-constrained underground utility corridors
• Aquaculture & Recirculating Systems — Gradual directional changes on 10" supply and return headers in large commercial aquaculture and water treatment facilities where hydraulic efficiency and low head loss through each fitting in the circuit support balanced flow distribution across the system
