STRAINERS Clause Samples
The 'Strainers' clause defines the requirements and specifications for installing strainers in a system, typically within piping or fluid handling equipment. It outlines where strainers must be placed, the type or mesh size to be used, and maintenance or inspection protocols to ensure proper operation. By setting these standards, the clause helps prevent debris from entering sensitive equipment, thereby reducing the risk of damage, blockages, or operational failures.
STRAINERS. A. Strainers shall be installed at all points shown on the plans. All strainers shall be cleaned prior to balancing, and again at completion of installation.
STRAINERS. A. Provide a "Y" type full size strainer as indicated on the Drawings.
B. An approved dirt blowout connection shall be made to each strainer, with 1" ▇▇▇▇▇▇▇ Figure 372 and Figure 658 cap and chain; the valve located six inches to twelve inches below the strainer. In the case of strainers under full water pressure, the blowout connection shall terminate at a point where there will be no risk of flooding or damage.
C. Strainers 2" diameter and smaller shall have screwed ends. Strainers 2-1/2" diameter and larger shall have flanged ends.
D. Strainers 2" and smaller shall be full size, bronze, "Y" pattern: ▇▇▇▇ Temco Figure IY, Spirax Sarco, ▇▇▇▇▇▇▇ or approved equal.
E. Strainers 2-1/2" or larger shall be cast steel body, "Y" type; ▇▇▇▇ Temco figure IY, Spirex Sarco, ▇▇▇▇▇▇▇ or approved equal, 150 psi rating.
F. Total open area of basket perforations shall be at least three times the inside area of pipes.
G. Strainer baskets shall be stainless steel with 1/16" perforations (up to 2" size) and 1/8" perforations (2-1/2" and larger).
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. 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. (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. The fire hydrant meter shall be capable of containing an internal strainer or orifice plate.
