Stainless Steel Symmetrical Reducer EN 10253-4A

The symmetrical concentric reducer for butt welding, manufactured from seamless stainless steel pipes in compliance with EN 10253-4, is a reliable solution for demanding pressure applications. Supplied with an EN 10204 3.1 material certificate, it ensures full traceability and quality assurance, making it a trusted choice across various industrial sectors. Widely applied in the construction of pipelines and installations, it also serves as a key component in welded ends for metal and rubber hoses, as well as in fittings and valve assemblies. Available in stainless steel grades AISI 321 and AISI 316Ti, the reducer offers working pressures ranging from 61 to 185 bar, depending on the diameter. For type A fittings, the pressure resistance may be slightly lower than that of a straight pipe of the same dimensions, with exact values determined using the correction factors specified in EN 10253 standards. Beyond standard sizes, customized solutions are offered, including reductions exceeding two DN sizes, ASME-compliant reducers, and a wide range of complementary butt-weld fittings such as 45° and 180° elbows, eccentric reducers, tees, and end caps. This versatility, combined with high durability and corrosion resistance, makes the product an excellent choice for industries seeking long-lasting, safe, and efficient pipeline components.
