Welcome to TOSHWIN TUBES INDIA

ECCENTRIC REDUCERS ANSI B 16.9

TOSHWIN TUBES INDIA manufactures reducers (pipe fitting) to reduce the diameter of the suction piping to fit the pump intake, thus used to join two pipes of different sizes. Reducers are available in both eccentric and concentric designs. Concentric or eccentric reducers are used to properly reduce into and out of circulating pumps.

The various advantages include keeping big pipes and small pipes together as well as reducing noise and vibration at the same time. Our reducers are tested and verified for durability, accuracy and precision.

TOSHWIN TUBES INDIA manufactures forged, seamless & welded reducers (pipe fitting) of types concentric reducer, eccentric reducers to ANSI B 16.5 from classes 2000 to 9000 and Schedules from 10 to 160.

TOSHWIN TUBES INDIA manufacture reducer's accordance with BS standard from classes 2000 to 9000 lbs, Schedule 10 to 160.
