### ИConsumer Product Description: Concentric Reducer Fitting Type A EN 10253-4 The Concentric Reducer Fitting Type A EN 10253-4 is a welded, in-line butt-welded fitting that provides a smooth transition between different pipe diameters. This transition fitting ensures conformity to EN 10253-4 standards and can be used in various industrial applications, including chemical processing, power generation, and oil and gas industries. #### Product Features and Benefits - **Material**: Manufactured from high-quality, corrosion-resistant austenitic and austenitic-ferritic (duplex) stainless steel. - **Concentric design**: Allows for a smooth transition between pipe diameters (DN 900 - DN 800) while maintaining a consistent flow rate. - **Easy installation**: In-line butt-welding (BW) offers maximum hermetic seal and robustness against impact loads, vibrations, and other external factors. - **European standards conformity**: Adheres to EN 10253-4 European standards for seamless and welded pipe fittings, ensuring safety, performance, and corrosion resistance at ambient, low, or elevated temperatures. #### Manufacturing Methods The Concentric Reducer Fitting Type A EN 10253-4 can be produced through two main methods: 1. **Welded method**: - Manufactured from either sheet metal or welded tubes in compliance with EN 10217-7 standards. - All welding processes must meet EN 10253-4 specifications and should be performed by certified welders. 2. **Seamless method**: - Produced through hot or cold stamping, hot rolling, or forging of seamless pipes. - These manufacturing methods offer high durability and versatility in industrial applications. #### Markings and Identification For clear product identification, markings using the following methods are applied: - Inkjet marking - Electrochemical etching - Fiber marking - Laser marking #### Quality Control and Testing The fitting undergoes stringent quality control measures and testing to ensure adherence to EN 10253-4 standards: - Chemical composition analysis - Tensile testing - Transverse tensile test for welded joints - Hardness testing - Bending test for welded joints - Charpy impact test - Intergranular corrosion resistance testing - Dimensional verification - Visual inspection - Non-destructive testing of welded joints #### Fitting Types There are two types of concentric reducer fittings available: 1. Type A: This fitting has the same wall thickness at the weld ends and the fitting body as the pipe with the same nominal thickness. Its resistance to internal pressure is lower than that of a pipe with the same specified diameter, wall thickness, and grade. For reductors, the wall thickness in the conical section must correspond to the specified wall thickness at the main end. 2. Type B: These fittings have thicker walls in the fitting body than Type A. They can withstand the same pressure as pipes with the same specified dimensions and grade. #### Applications and Industries The Concentric Reducer Fitting Type A EN 10253-4 can be used in various industries and applications, such as: - Oil and gas industry - Chemical processing - Mechanical engineering - Agriculture - Medicine - Pharmaceuticals - Power generation #### Technical Specifications The technical characteristics of the fitting cover: - Fitting type: concentric - Manufacturing method: welded - Connection type: BW – in-line butt welded - Standard: EN 10253-4 - Type: Type A - Nominal diameter DN: 900 - Nominal diameter DN2: 800 - Outside diameter D: 914 mm - Outside diameter D2: 813 mm - Wall thickness T: 12.5 mm - Wall thickness T1: 12.5 mm - Maximum angle of inclination αmax: 10° - Length L: 610 mm In conclusion, our organization is dedicated to providing reliable and high-quality welded, in-line concentric reducer fittings for the most demanding industrial applications. Strict adherence to EN 10253-4 European standards ensures safety, performance, and durability for all our product offerings.Города по доставке металлопроката
