Product Detail

90 degree elbow tee reducer steel Butt weld pipe fitting elbow

Carbon steel butt weld pipe fittings—including 90-degree elbows, tees, and reducers—form the essential skeletal framework for directing, branching, and modifying fluid flow in industrial piping systems. Manufactured from robust ASTM A234-grade carbon steel, these fittings are engineered for permanent, leak-free connections through butt welding, offering superior strength and integrity compared to threaded or socket weld alternatives.

These components are precision-formed to meet ASME B16.9 dimensional standards, ensuring perfect alignment and fit-up with matching schedule pipes. The 90° elbow facilitates directional change with minimal pressure loss, the tee allows for branch connections, and the reducer manages pipe diameter transitions. Designed for seamless integration into high-pressure and high-temperature systems in sectors like oil & gas, power generation, and chemical processing, they provide a reliable, maintenance-free solution for constructing durable and efficient piping networks.

BUTT WELDED PIPE ELBOW

Steel pipe elbow is a key parts in a piping system for to change the fluid flow direction. It is used to connect two pipes with same or different nominal diameters, and to make the pipe turn to a certain direction of 45 degree or 90 degree.

For industrial pipe elbow, the connectin end type is butt weld, according to ANSI B16.25. Butt welded can described butt welding, buttweld, bevel end. BW

ELBOW TYPE

Material & Manufacturing: Fittings are fabricated from ASTM A234 WPB (standard carbon steel) or other alloy grades (WP5, WP11, etc.) for high-temperature service. They are produced through hot forming (forging or induction bending) or cold forming processes, followed by heat treatment (normalizing) to relieve stresses and restore mechanical properties. This ensures uniform grain structure and enhanced durability.

Precision Engineering: Critical dimensions—such as center-to-end (elbow), center-to-face (tee), and overall length (reducer)—are machined to tight tolerances per ASME B16.9. The inside and outside surfaces are smooth to minimize turbulence and erosion. All weld ends are precision-beveled (37.5° ± 2.5°) with a consistent land to ensure full penetration during welding and optimal joint strength.

Design Variants:

90° Elbow: Available in Long Radius (LR, 1.5D bend radius) for smoother flow and lower pressure drop, and Short Radius (SR, 1D bend radius) for space-constrained installations.

Tee: Equal Tees have the same branch and run sizes; Reducing Tees feature a smaller branch size, allowing for flow division or equipment connection.

Reducer: Concentric Reducers maintain the centerline, used in vertical lines. Eccentric Reducers have an offset centerline, crucial for horizontal pump suction lines to avoid air pocket formation.

Quality Marking: Each fitting is permanently marked with the material grade (e.g., A234 WPB), size, schedule, manufacturer's logo, and heat number (for traceability), in compliance with ASTM A960.

ELBOW SURFACE

Sand Blast

After hot forming, we arrange sand blast to make the surface to be clean and smooth.

After Sand blast, to avoid get rust, should do black painting or anti-rust oil, Hot dip galvanized (HDG) , epoxy, 3PE, vanished surface, etc. That is depend on customer's request.

HEAT TREATMENT

1. Keep sample raw material to trace.
2. Arrange heat treatment as per standard strictly.

MARKING

Various marking work, can be curved, painting, lable. Or on your request. We accept to mark your LOGO.

PACKAGING& SHIPPING

Packaging: Fittings are carefully packaged to prevent damage during transit. Standard protection includes coating with anti-rust oil or VCI (Vapor Corrosion Inhibitor) and individual wrapping in plastic or waterproof paper. The beveled ends are protected with plastic or steel caps to preserve the welding surface. For bulk orders, fittings are palletized and secured with steel straps, then covered with shrink wrap. Large-diameter or heavy fittings are crated in custom wooden boxes with internal bracing.

Marking & Documentation: Each package is labeled with the product description, size, material, quantity, and PO number. Shipping documents include a detailed packing list, commercial invoice, and material certificates.

Shipping: We offer flexible shipping solutions via sea container (FCL/LCL), air freight, or land transportation. For project cargo, we coordinate with specialized freight forwarders to handle oversized fittings, ensuring safe and timely delivery to global destinations.

Wide-Ranging Industrial Applications: These butt weld fittings are fundamental components across numerous sectors:

Oil & Gas: Onshore/offshore pipelines, refinery process piping, wellhead manifolds, and compressor stations.
Power Generation: Main steam and feedwater lines in thermal plants, cooling water systems, and fuel gas piping.
Chemical & Petrochemical Plants: Reactor feed lines, distillation column piping, heat exchanger connections, and corrosive fluid handling systems.
