Haihao Group Delivers BS EN 10253-4 Type A Concentric Reducer to Singapore Client

Haihao Group has completed shipment of a precision stainless steel concentric reducer for a Singapore cryogenic piping project. This reducer has an outer diameter of 48.3 mm × 42.4 mm and 2.6 mm wall thickness, manufactured to BS EN 10253-4 Type A. A special material arrangement applies: chemical composition follows 1.4404, while mechanical properties meet the requirements of 1.4401, with validated impact performance down to -196°C.

The BS EN 10253-4 Type A concentric reducer is built to suit demanding low-temperature service. Cryogenic systems leave little margin for material inconsistency, so we strictly control melting chemistry to 1.4404 limits while verifying tensile and toughness performance against 1.4401 values. This flexible material specification is often requested by Singapore engineering teams for cold process and liquefied gas piping.

BS EN 10253-4 Type A concentric reducer, 1.44041.4401 stainless steel for Singapore cryogenic piping

Our QC workflow for this BS EN 10253-4 Type A concentric reducer includes dimensional inspection, material heat number verification and low-temperature impact testing at -196°C. Type A under BS EN 10253-4 means the fitting is suitable for full pressure rating matching the connected pipe, a key detail for designers calculating system pressure boundaries. The smooth concentric transition keeps flow disturbance low inside the piping circuit.

Many buyers in Singapore struggle to source fittings that satisfy this dual material specification, where chemistry and mechanical property references differ. We maintain clear documentation separating the 1.4404 chemical report and 1.4401 mechanical results, so inspectors can quickly validate compliance on site. This BS EN 10253-4 Type A concentric reducer is machined and finished with clean surfaces, ready for butt welding into cryogenic lines.

If your project requires stainless steel reducers for cryogenic or corrosive service, share your OD, thickness and material specification with our technical team. We can arrange BS EN 10253-4 Type A concentric reducer and matching fittings with full test certificates tailored to your specification.
