Johnson Screens Flush Threaded PVC Casing and Slotted Pipe Specifications

All Johnson Screens Flush Threaded PVC pipe and screen products are manufactured from plastic of Type 1, Grade 1, PVC compound with a cell classification of 12454-B per ASTM D1784. Pipe materials are NSF approved for potable water and are in strict compliance with ASTM D1785.

To maintain the integrity of the slotting and threading process, the only coolant used is air.

*Based on GF Harvel Engineering Guide


Custom lengths up to 20 ft. can be provided on request. Laying (makeup) length is standard for commonly used materials such as 1, 2, 4, 6 in. diameter Schedule 40 and 80 PVC. Other sizes are end-to-end length unless specified. Standard threads per inch (TPI), for pipe sized .5 -1 in. is 8 TPI, 1.25 - 1.5 in. is 4 TPI, and 2 in. and up is 2 TPI. Customized screen products for special pipe lengths, slot sizes, slot spacing and thread types are available to meet specifications. All flush threaded material is supplied with an O-ring. All environmental screens and casings, up to 8 in. diameter, are cleaned and bagged prior to shipment.

Temperature De-Rating Table

Curing of cement and grout generates sufficient heat to affect PVC strength and performance. When operating at elevated temperatures, the actual values for Collapse Pressure, Burst Pressure and Tensile Strength will be de-rated according to the chart.
