Strainers. All meters shall be provided with a strainer screen installed in the meter. Strainer screens shall be rigid, fit snugly, be easy to remove and have an effective straining area at least two (2) times that of the main case inlet.
Strainers. Meters shall be provided with separate external bronze case or strainer built into the inlet end of the stainless steel plate type with a removable cover plate permitting easy access to the strainer for routine cleaning. They shall be rigid, easily removable and have an effective straining area at least double that of the meter main case inlet. Separate external strainer connections shall conform to the main case and shall be accompanied by gaskets, bolts and nuts.
Strainers. (i) The strainers shall be of the automatic and manually operated self-cleaning type, with mesh openings of not more than 3 mm and in any case small enough to exclude any foreign matter large enough to cause damage or blocking in any part of the system.
(ii) Any discharge from the strainers resulting from a backwash of flushing cycle shall be piped to drain. The mesh shall be of corrosion resistant material and the strainer bodies and covers shall be galvanized internally and externally.
(iii) The strainers shall each have an automatic air release valve with discharge piped to drain. The head across the strainer when 30 percent blocked shall not exceed 1.5 m of water.
Strainers. Air and Gas Strainers: 1. Unless otherwise indicated, air and gas line strainers shall be Y-pattern with 40 mesh Monel
Strainers. All strainers shall be of 16 bar working pressure rating. Strainers shall be y -type, bronze body with 26-mesh stainless steel screen with 0.8 mm diameter perforations. Strainers shall be threaded to BS 21.
Strainers. Install strainer(s) as shown on piping diagrams. The strainer is required to protect the heat exchanger, control valve, meter and the DES's primary system. The strainer requires upstream and downstream pressure taps for strainer service inspection as well as the ability to read supply and return pressure through use of one pressure gauge. Blowdown of the strainer is the responsibility of the building owner. Maximum allowable pressure drop across strainer is 2 PSIG. The stainless steel screen shall be sized according to requirements for the HX and/or control valve, whichever requirement is finer.
Strainers. Strainers shall be provided on the inlet side of any chilled water coil to protect the cooling coil from debris blockage. The strainers shall have a Cast iron or bronze body with threaded or flanged connection with a threaded blow off cover and removable stainless steel screen with .045” perforations. Larger screens are not acceptable.
Strainers. TS-439 Approved “self-cleaning” strainers shall be fitted in the section line of each pump and at the inlet connections to each feeder and make-up connections, and each automatic control valve of all apparatus of an automatic character, whose proper functioning would be interfered with by dirt on the seat or by scoring of the seat. All strainers shall be suitable for pressures as stipulated for the system concerned and are to be inspected and pressure tested at the works. All strainers shall be cast iron or bronze bodied of ample strength for the pressure to which they shall be subjected with suitable flanges or tapping to connect with the piping they serve. Strainers basket screens shall be stainless steel and shall be of ample strength to prevent collapsing the basket under shock loading. TS-440 Each water strainer shall be provided with an approved valve dirt blow-out connection suitably piped to the nearest floor drain.
Strainers. The fire hydrant meter shall be capable of containing an internal strainer or orifice plate.
Strainers. Strainers shall be designed for a minimum delta pressure across the strainer of 1.0 kg/cm2. Pump suction strainer usage is to be reviewed for type of operation. Mesh sizing is to be determined considering type/quality of pumping media.
