It is recommended to support the strainer body through use of a hanger or other type of support structure within the process piping. The end cap must be tightly fitted into the end of the element prior to installing the element in the strainer housing. The end cap is designed to lock in place as long as the x-ring is installed. The end cap should feel secure after installation without any looseness to the assembly.
If twisting the end cap is overly difficult, apply water to the x-ring seal area to ease the twisting action.
Ensure the ALB strainer is installed for ease of access with plenty of space for full removal of the perforated element insert. Use adequate piping supports to support the strainer so it does not move during production, and to ensure the clamp connections are not overly stressed. Isolation valves can be used upstream or downstream of the strainer to assist with element insert removal by reducing the amount of product/water that will spill out when opening the ALB strainer. As the ALB strainer becomes plugged with debris, the differential pressure will increase. Typically, noticeable differential pressure increases occur once the strainer is more than 80% fouled. A fully soiled strainer that completely stops the flow will result in a pressure drop equal to that of the dead-head pressure of the supply pump which could damage strainer components. It’s recommended to monitor the pressure and make a change once the pressure drop exceeds typical pressure drops. As noted in Table 1, the maximum allowable pressure drop is 40 psi.
Assembly The ALB component assembly contains 12 sub-components (depending on selected configuration):
1. Element Gasket 2. Sample Valve - Optional 3. Element O-Ring 4. Element Tri-Clamp 5. Element (Perforated) 6. End Cap X-Ring 7. End Cap 8. Pressure Gauges (Qty. 2) – Optional 9. Strainer Body (Upper) 10. Pressure Gauge Clamps (Qty. 2) - Optional 11. Pressure Gauge Gaskets (Qty. 2) - Optional 12. High Pressure Body Clamp 13. Sight Glass Gaskets (Qty. 2) - Optional 14. Sight Glass Window - Optional 15. Strainer Body (Lower)
The mesh underlay (if included) is first slid inside of the perforated element. The end cap is then fastened to the retaining ring (end of element) using the quarter turn latching nobs, turning the end cap in a clockwise direction. The full element assembly is then slid inside of the body of the ALB strainer.
