Two root centerline concentric reducer pipe connected in a straight line, mainly for upright pipeline. More eccentric reducer used in the horizontal line. With a straight section diameter pipe, GB12459 (DN20x15 ~ 500 ~ 300) manufactured by the seamless; without straight section diameter pipe, molded reducer, GB / TI. MOI (DN350 × 300 ~ 1200 × 1000) made of steel or steel. Usually. Large diameter pipe connection using cheap steel or steel with a diameter pipe manufacturing prices, the economy is good, but without a straight section diameter pipe, aligned with the welding groove than at the straight section diameter pipe to be difficult. In small diameter pipes (DN50 or less), it is also often used in place of a short section diameter as the pipe diameter pipe reducers. Reducing short section also has concentric and eccentric points.
