FRP PIPE FITTINGS, SPECIAL-SHAPED PARTS,PROFILES
These are key fittings in fiberglass piping systems used to connect pipes of different diameters. Their main function is to change the flow rate and velocity of the piping system.

I. Types and Specifications
Based on their geometry, reducers are mainly divided into two types:
1. Concentric Reducers
Characteristics: The streamlines change symmetrically as fluid flows through.
Applications: Most vertical pipes and horizontal pipes without special requirements for fluid distribution.
2. Eccentric Reducers
Characteristics:
Flat Bottom Eccentric: The flat side is at the bottom. This is the most commonly used eccentric reducer, used in horizontal pipes. It prevents air pockets from forming at the reducer, facilitates venting, and maintains a consistent bottom elevation of the pipe.
Flat Top Eccentric: The flat side is at the top. Less commonly used, it can be used to prevent solid particles from accumulating at the top.
Applications: Horizontally installed pump inlet pipes, pipes requiring venting to prevent gas accumulation; or situations where a specific pipeline elevation needs to be maintained.
II. Main Application Areas
Pump Inlet and Outlet:
Pump Inlet: Typically uses an eccentric reducer (flat bottom) to prevent gas buildup at the pump inlet and protect the pump impeller. Installation must be "flat top," meaning the flat section is at the top, to achieve automatic venting.
Pump Outlet: Typically uses a concentric reducer, connected to an enlarged pipe to reduce flow velocity.
Connection between Piping System and Equipment Interface: When equipment interface dimensions do not match pipe dimensions.
Process Flow Requirements: In pipe sections where flow velocity needs to be changed to match process requirements.
All FRP piping systems requiring diameter changes.
