WPB B16.5 is a type of pipe fitting that is commonly used in industrial piping systems. WPB stands for "wrought pipe fitting of black" and B16.5 refers to the American Society of Mechanical Engineers (ASME) B16.5 standard for pipe flanges and flanged fittings.WPB B16.5 pipe fittings are made from black steel and are designed to be welded onto pipes to create a secure, leak-resistant connection. They are available in various sizes and shapes, including elbows, tees, reducers, and caps.The B16.5 standard specifies the dimensions, materials, and testing requirements for pipe flanges and flanged fittings. This includes the dimensions of the [...]

What are the differences between concentric and eccentric reducers?

tsadmin|2023-03-16T03:47:22+00:0016 3 月, 2023|分类：Uncategorized|标签：concentric, eccentric, reducers|

Concentric and eccentric reducers are two types of pipe fittings used to connect pipes of different sizes. The main differences between them are:1. Shape - Concentric reducers have a symmetrical shape with a straight centerline, while eccentric reducers have an offset centerline, resulting in a curved shape.2. Flow direction - Concentric reducers provide a straight flow path between pipes of different sizes, while eccentric reducers provide a curved flow path.3. Applications - Concentric reducers are commonly used in vertical piping systems, while eccentric reducers are commonly used in horizontal piping systems.4. Pressure drop - Concentric reducers have a lower pressure [...]
