The ASTM A234 WP12 CL2 Reducer is a high-performance pipe fitting designed for connecting pipes of different diameters in pipeline systems. It is specifically engineered for medium-to-high temperature and high-pressure conditions, making it suitable for steam pipelines in nuclear and thermal power plants, as well as high-temperature systems in petrochemical industries.
The ASTM A234 reducer features a centerline alignment design, used to reduce large-diameter pipes to smaller diameters. It is suitable for vertical pipeline systems, ensuring smoother fluid flow to minimize losses caused by turbulence and pressure. The seamless manufacturing process and heat treatment eliminate weld defects, enhancing the fitting’s pressure resistance and ensuring structural integrity and long-term reliability in demanding conditions.



A234 WP12 CL2 Concentric Reducer
The ASTM A234 WP12 CL2 concentric reducer from C&N complies with the ASTM A234 WP12 material standard and the ASME B16.11 CL2 (2000 lb class) pressure rating. It can withstand pressures up to 5000 psi and operate reliably in harsh environments ranging from -29°C to 593°C for extended periods.
ASME B16.9 Eccentric Reducer
The eccentric butt-weld reducer, which conforms to ASME B16.9, is a pivotal fitting used in piping systems to connect two pipes of different diameters at an offset. Its design is essential for maintaining proper pipe alignment, which is critical in applications where fluid or gas pooling could cause problems, such as in slurry or gas systems.
Eccentric reducers are available in sizes ranging from 1/2″ to 48″ NPS and are versatile enough for various industrial applications, including oil and gas, chemical processing, water treatment, and power generation. The butt weld ends ensure a secure, leak-proof connection, which is crucial for system integrity.
Eccentric reducers are particularly valuable in horizontal pipelines or pump suction lines where maintaining consistent pipe alignment or preventing sediment accumulation is critical. Their design adheres to ASME B16.9 standards, ensuring compatibility and interchangeability with other piping components and facilitating efficient fluid handling and system performance.

The ASTM A234 WP12 CL2 reducer is made of chromium-molybdenum alloy steel, known for its high yield strength (≥275 MPa) and excellent weldability. Its core components include chromium (0.8-1.25%) and molybdenum (0.44-0.65%). By strictly controlling the chromium content, the ASTM A234 WP12 CL2 concentric reducer significantly improves resistance to high-temperature oxidation, hydrogen corrosion, and creep. Additionally, the CL2 grade offers enhanced pressure-bearing capacity compared to CL1, making it a cost-effective choice for severe operating conditions.
