Spears SCH 80 1 Blind Flange Polypropylene SR Threaded Fitting
Patented Special Reinforced (SR) Thread Design
Spears patented Special Reinforced (SR) thread design is one of the most significant advancementsin the use of plastic threaded fittings. More than just an added metal ring, this unique precompressiondesign compensates for expansion forces generated from tapered pipe thread joint make-up. Radialstress is reduced in normal installations and contained in severe over tightening situations. SRstyle fittings use type 316 Stainless Steel reinforcement.Full 150 psi Pressure Rating For Threaded Systems Using SR Threaded FittingsSpears SR threaded Schedule 80 Polypropylene fittings provide the reinforcement necessary toprovide threaded systems with full 150 psi pressure rating for water @ 73 F, typically found onlyin fusion welded systems.High Grade Homopolymer Compound - Excellent Chemical ResistanceSpears selection of a premium polypropylene homopolymer provides improved purity withexcellent chemical resistance to many solvents, caustic solutions and mixed chemicals for a widevariety of applications. Available in natural or black materials. (For black, please call 818-340-7258 for pricing)
Spears Patented SR Technology
Boosts Threaded Polypropylene Fitting PerformanceImproved Pressure Handling PerformanceDue to the highly ductile nature of Polypropylene, most threaded PP fittings are rated for system pressuresof 25 psi @ 73 F. Pressure applications of up to 150 psi generally require more costly fusion weld jointingmethods or use of a glass-filled material which limits chemical resistance for some applications. Spears Special Reinforced (SR) thread design boosts threaded PP fitting performance by containment of expansionforces generated both during threaded joint make-up and higher system pressure operation. Laboratorytest assemblies of Spears Schedule 80 SR Polypropylene threaded fittings have been subjected to ASTMD 1598 sustained pressure test for 1000 hours at 320 psi without failure or loss of joint integrity.
Sound PP Threaded Connections
Spears recommends use of Spears BLUE 75 Thread Sealant for all SR threaded PP system connectionsto insure chemical compatibility and joint integrity. Tape type thread sealant can cause unwanted wedgingaction between threads. Choice of an appropriate thread sealant is at the discretion and responsibility ofthe installer. Spears Schedule 80 SR Polypropylene fittings are assembled with an adhesive to positionthe reinforcing ring. If ring is loose, simply check that it is seated against the face of the fitting whenassembling joint. A loose or spinning ring does not reduce its function upon installation. 1 to 2 turnsbeyond finger tight are generally sufficient to make a sound joint. Unnecessary over tightening can resultin stripping of threads or other pipe and fitting damage.
