The fiberglass reinforced plastic basket strainer shall be designed for continuous contact with corrosive fluids operating at elevated temperature and pressures. These strainers are designed for maximum resistance to austere environments without sacrificing ergonomics for maintenance personnel. Baskets are designed to remove foreign particulate that could damage pump impellers or foul process equipment.

2.1.1. Strainer type shall be flanged basket. 2.1.2. Standard configuration is in-line. Other configurations may incur additional

pressure drop. 2.1.3. Interface dimensions shall be interchangeable with Fluidtrol P series design

shown in table below to minimize installation costs. Standard dimensions may not meet ASME BPVC vessel nozzle minimum length. Deviation from dimension A can be made to meet customer facility code requirements.

2.2. Flanges 2.2.1. Flanges shall be ASME/ANSI 16.5 Class 150 and manufactured per PS-15-69 and

ASTM D5421. 2.2.2. Flange bolt holes are spot faced and coated with resin. 2.2.3. Drain flange shall be a minimum of ½” diameter.

2.3. Basket 2.3.1. Basket material shall be PVDF with 1/4” perforation on 3/8” centers. 2.3.2. Basket shall have handle attached to body, capable of holding 50lbs of debris. 2.3.3. Basket shall be able to withstand 5 psi pressure drop across the perforated wall. 2.3.4. Basket open area shall be 10 times greater than influent cross-section area.

2.7.4. The body shall have a 100 mil chemical resistant liner with 10% glass content, an anti-wicking layer of chopped mats with 25% glass content, and a structural filament wound layer with up to 65% glass content.

2.7.5. Exterior coating shall have a minimum 10 mil layer of unsaturated polyester resin based, high quality gel coat with UV protective inhibitors to maximize service life.

3. MANUFACTURER3.1. Manufacturer shall have minimum five year service history in industry.3.2. Manufacturer shall maintain as-built dimensions of each strainer.3.3. Manufacturer shall be ISO 9001:2008 Certified.3.4. Manufacturer shall supply minimum one year warranty on lids, baskets, and gaskets to

cover defect in material or workmanship. 3.5. Manufacturer shall supply minimum five year warranty on FRP shell to cover defect in

material or workmanship. 3.6. Known Approved manufacturers

Strainer Specification Tables

Getting as much information available during the initial stages of a strainer design is critical. We do

understand how design criteria changes as projects develop and we are very reactive to these variations.

The information in the tables to the right will most likely not be com-pletely available at the onset of a

project, but should be filled out as well as possible for optimal strainer design.

Strainer IdentificationAll strainers are given a serial num-ber for future reference and this is affixed to each strainer that leaves the factory. Substantial records are kept at the factory for future refer-ence. Therefore, in the event the end user needs assistance, parts or re-placement, Fluidtrol is able to iden-tify the exact strainer in question by referencing this. Even special cir-cumstances of each individual unit
