Strainers with Inbuilt Blowdown Valves

Indo Anushka offers “Mainteno” Y-type and T-type Strainers with inbuilt blowdown valves and facility of online cleaning. Strainers traditionally available in the market, Y-type/T-type (basket strainers also in T-type) are installed before equipments on supply lines of fluid, gas, steam, etc., and are used for removing (straining) solid particles from the fluid. All strainers gradually get choked due to the straining of the solid particles and collection of the same inside or before the screen. All traditional strainers (Y-type, T-type including basket type) are then required to be isolated, opened and cleaned. Choking of these strainers, which is a repeatable and ongoing process, therefore involves shutdown, investment of time or investment in duplex strainers or losses by opening of bypass in case of steam trap modules. “Mainteno” Y-type and T-type strainers actually take care of all these challenges. Blowdown in the direction of the flow enables all collected solid particles to be blown out by opening the blowdown valve online. The unique feature of flow from inside to outside the screen cylinder of T-type Maintenos not only helps to collect the solid particles but also helps to blowdown the collected solid particles with the help of the flow itself. Also due to the inherent blowdown valve at the bottom, the fluid outside the strainer screen gets sucked in and therefore flushing and back flushing takes place in one stroke itself. T-type Maintenos are made by rigidly following the ratios of screening area to flow area as 2 to 4, which is as per international standards. Therefore pressure drop across the strainer in clean conditions is nearly zero. The unique feature of Maintenos to enable online cleaning results into tremendous savings in terms of total prevention of shutdowns, continuous hassle free running of down the line equipments, saving of manpower for opening and cleaning of strainers, loss due to leakages because of opening of bypasses and saving by elimination the requirement of installing of any duplex or standby strainers.
