Concentric reducers are a symmetrical, conical shaped device that enlarges or reduces a pipes diameter equally about the centerline. An Eccentric reducer is not Symmetrical about the centerline.
For example, envision the flow through a gravity based pipe... picture it in terms of an elevation section view... the eccentric reducer maintains the flowline (a straight continuous line along the bottom) while the pipe size decreases from the top down.
Concentric refers to a type of muscle contraction where the muscle shortens as it generates force, such as when lifting a weight. Eccentric, on the other hand, refers to a muscle contraction where the muscle lengthens as it generates force, such as when lowering a weight. Both types of contractions are important for muscle strengthening and control.
Eccentric muscle contractions involve the lengthening of the muscle under tension, which allows for greater force production compared to concentric contractions where the muscle shortens. This occurs because the muscle fibers can generate more force during the controlled lengthening process in eccentric contractions, leading to greater tension development.
Isotonic muscle contractions involve both concentric (muscle shortening) and eccentric (muscle lengthening) phases. In isotonic contractions, the muscle changes in length while maintaining a constant tension, such as when lifting a weight or performing a bicep curl.
The correct phase order of the stretch-shortening cycle is eccentric contraction, amortization phase, and concentric contraction. This sequence allows for energy storage during the eccentric phase, a brief pause to transition from lengthening to shortening, and then rapid muscle shortening in the concentric phase for powerful movement.
Eccentric motion refers to a type of muscle contraction where the muscle lengthens while generating force, as opposed to concentric motion where the muscle shortens while generating force. It is commonly used in resistance training to build strength and control in muscles.
The spring coil effect in muscles refers to the ability of muscles to store energy during an eccentric contraction (lengthening phase) and release it during a concentric contraction (shortening phase). This mechanism helps to enhance the efficiency of movement and improve athletic performance by utilizing elastic energy.
Let me know about the usage of Eccentric and Concentric pipe intersection in oil and gas industry? What are the major differences and concerns about Eccentric and Concentric pipe intersection in oil and gas industry?
Concentric
In Resistance Training, concentric and eccentric contractions are two movements done by opposing muscles. Eccentric contractions are said to cause delayed onset of muscle sorennes( DOMS).

Concentric and eccentric movements.
A squat involves both eccentric and concentric muscle contractions. The lowering phase where you bend your knees and lower your body is the eccentric phase, while the rising phase where you extend your knees and stand up is the concentric phase.

Concentric swage is used for small bore piping while concentric reducer is used for large bore piping. Zach
Concentric, which is an adjective meaning, "having a common center".electric
