Butt Welding Reducers

Butt Welding Reducers

We manufacture of butt weld pipe fittings to meet diverse material specification. Reducers be applied, to change from pipe diameter in one direction. Standard there are 2 possibilities, the concentric reducer, is usually used in vertical pipe lines, and the eccentric reducer that is used in horizontal pipe lines.

Types: Concentric & Eccentric Reducers

Dimensional Tolerances of Concentric and Eccentric Reducers ASME B16.9
