Temporary Plate Strainer Applications
• System startup and commissioning: temporary protection of pumps, valves and heat exchangers during initial system operation and pipeline flushing.
• Oil refinery and petrochemical: pipeline flushing and commissioning in refineries and petrochemical plants, removing weld slag, rust and debris.
• Power plant: temporary filtration in feedwater, condensate, cooling water and steam systems during plant startup and maintenance.
• Water treatment: commissioning of municipal water networks, pumping stations and treatment plants with temporary plate strainer installation.
• Chemical processing: temporary filtration of corrosive media during system flushing, with SS316 or DSS construction.
• HVAC and marine: temporary protection in HVAC systems and marine pipelines during construction and commissioning.
FAQ - Temporary Plate Strainer
Q1: What is a Temporary Plate Strainer?
A: A Temporary Plate Strainer (also called Temporary Flat Strainer) is a temporary filtration device with a flat perforated plate and ring flange, mounted between two flanges in the pipeline during system startup, commissioning or maintenance. It protects pumps, valves, meters and other critical equipment from debris such as weld slag, rust, scale and foreign materials. The plate type is the most economical and simplest among temporary strainers, with the lowest pressure drop. After the system is cleaned, the temporary plate strainer is removed and replaced by a spacer or permanent strainer.
Q2: What is the difference between Plate, Conical and Basket Type Temporary Strainer?
A: Plate Type has a flat perforated plate with ring flange, offering the lowest pressure drop and cost for horizontal pipeline temporary protection. Conical Type has a cone-shaped screen with ring flange, suitable for general start-up service and pump suction protection. Basket Type has a cylindrical basket screen with ring flange, providing the largest filtration area for high dirt load and system flushing service. All three types are available from 3/4 inch to 36 inch (Plate type up to 24 inch), and can be manufactured in SS304, SS316, DSS and Monel.
Q3: What materials are available for Temporary Plate Strainer?
A: Main materials include 304SS, 316SS and DSS (duplex stainless steel). SS304 is the standard and most economical choice for general water, HVAC and non-chloride service; SS316 is selected for chloride-containing and corrosive media; DSS 2205 / 2507 are used for seawater, desalination and offshore service where high chloride resistance is required. Perforated hole size and mesh size are tailor-made to customer requirements. Please specify the material and perforated hole size when requesting a quotation.
Q4: What is the size range and pressure rating available?
A: Temporary plate strainers are available from 3/4 inch to 24 inch (DN20 to DN600). Pressure ratings include Class 150LBS, 300LBS, 600LBS, 900LBS and 1500LBS. Flange standards include ASME B16.5 and DIN EN 1092-1. The temporary plate strainer is mounted between two standard flanges in the pipeline, and its ring flange dimension matches the mating flange standard. Special dimensions and larger sizes are available on request. Please specify the flange standard and pressure rating when requesting a quotation.
Q5: How is the Temporary Plate Strainer installed?
A: The temporary plate strainer is installed between two flanges in the pipeline. The ring flange is sandwiched between the two mating flanges, and the bolts are tightened to compress the gasket and secure the strainer. Unlike the conical and basket type, the plate type is bi-directional, so there is no specific flow direction requirement. Installation is quick and does not require welding or special tools. The plate type is particularly suitable for horizontal pipeline where the plate sits flush between the flanges. After system flushing or commissioning is complete, the temporary plate strainer is removed by loosening the flange bolts.
Q6: When should I choose Plate Type over Conical or Basket Type?
A: Choose Plate Type when: (1) You need the most economical temporary protection solution. (2) The dirt load is low to moderate and simple perforated plate filtration is sufficient. (3) The pipeline is horizontal and the plate can sit flush between the flanges. (4) The pressure drop requirement is critical and the lowest possible pressure drop is preferred. Choose Conical Type for general start-up service where a conical screen provides larger filtration area than the plate. Choose Basket Type for high dirt load and system flushing where the largest filtration area is required. Please refer to our Temporary Conical Strainer and Temporary Basket Strainer pages for more information.
