Butt-Weld Fitting
A reducing butt-weld cross connects four pipes where not all outlets are the same size. This single fitting handles the transition from a larger main to smaller branches, reducing the number of welds and individual fittings required in a manifold or distribution header. Manufactured to BS EN 10253-2 and ASME B16.9, the run and branch combinations are tailored to your design requirements.
All reducing crosses are supplied with bevelled weld ends for full-penetration butt welding. Each fitting is supplied with heat numbers and material test certificates, providing complete traceability from raw material through to the finished product.
Produced in accordance with BS EN 10253-2 and ASME B16.9 in carbon and stainless steel grades suitable for UK process and utility pipework.

| 8" | 200 | 4" | 100 |
A single reducing cross replaces a conventional equal tee with a reducer, eliminating at least one weld joint and reducing overall fitting length. The result is a more compact manifold layout, lower material cost and fewer potential leak paths. Streamlined internal geometry also reduces turbulence at the branch take-off, improving flow efficiency in distribution systems.
Ideal for compact manifolds, retrofit tie-ins and process skids across the UK where multiple different branch diameters meet at a single point. Commonly specified in petrochemical secondary distribution piping, building-services risers, cooling-water manifolds and fire protection systems where space and weight savings are critical.
Every fitting is manufactured to BS EN 10253-2 and ASME B16.9 and supplied with full material traceability and EN 10204 Type 3.1 test certificates. Heat numbers are recorded throughout production to support inspection, QA and UK project-compliance requirements.
