Carbon Steel Weld Pipe Fittings

Common welded piping connections include butt-welded connections and socket-welded connections. Butt welding joins prepared pipe and fitting ends directly, while socket welding inserts the pipe into a recessed fitting socket before welding. The appropriate connection depends on the piping design, dimensions, service conditions, standards, and project specifications.

Socket-weld fittings receive the pipe into a socket and are welded around the joint. Buttweld fittings align with the pipe end and are joined along the prepared edges. Butt-weld fittings are commonly selected for continuous piping runs and high-flow systems, while socket-weld fittings may suit smaller piping arrangements where their connection method is specified.

The listed product range includes long- and short-radius elbows, concentric and eccentric reducers, equal and reducing tees, pipe caps, and crosses. Carbon steel options include A234 WPB, alongside stainless steel A403 WP304/316 and alloy steel alternatives. Availability should be confirmed against the required fitting type, dimensions, wall thickness, and standard.

The product information identifies ASME B16.9, ASME B16.28, and MSS-SP-75 as applicable standards for the listed fittings. The broader product data also references the ASME B16 series and ASTM standards. Confirm the required standard and documentation with your project specification before ordering, particularly for high-pressure or high-flow piping service.

The listed industrial pipe and fitting range covers sizes from 2" through 72" and wall thicknesses from SCH 10 through XXH. Actual availability varies by fitting configuration, material, and specification. Provide the required nominal size, schedule or wall thickness, fitting type, and material when requesting a quotation.

Selection starts with the connection type, nominal pipe size, wall thickness, fitting geometry, material, and applicable standard. Consider whether the system needs an elbow, reducer, tee, cap, or cross, and whether the design calls for carbon, stainless, or alloy steel. Project pressure, flow, welding, and inspection requirements should also be reviewed.
