The material system for reducers is identical to that for tees and elbows. Selection is mainly based on the conveyed medium (corrosiveness, temperature, pressure) and service environment (industrial/civil, buried/aboveground). Materials are primarily divided into two categories: metallic and non-metallic. The detailed classification and applicable scenarios…

The “rating” of a reducer mainly refers to its pressure rating (pressure-bearing capacity) and wall thickness rating (directly related to pressure). Two major systems are widely used globally: the metric system (PN) and the American standard system (Class / Sch). For some plastic reducers, the…

The dimensions of a reducer mainly include four key parameters: nominal diameter (large end / small end), length, taper angle, and wall thickness, in accordance with standards such as GB/T (Chinese) and ASME (American). Clear standard dimensions are specified for different types (concentric / eccentric)…

Reducers can be classified according to core dimensions such as structural form, manufacturing process, connection method, material, and pressure rating. Different classifications correspond to different application scenarios and technical requirements. The systematic and clear classification system is as follows: I. Classification by Structural Form (The…
