Acid Waste Piping Design Data Installing Drainage …

1 Installing Drainage SystemsProper installation of Orion Drainage sys-tems is extremely important in assuring thatinstallations perform flawlessly for years. Supporting a Drainage SystemSince Polypropylene has a higher expan-sion rate than that of other materials, it cannotbe anchored to restrict movement from ther-mal expansion incurred from chemical reac-tions or the inadvertent dumping of hot waterinto the acid Waste recommends the use of clevis orloop type pipe hangers. If split-ring or otherhanger types are used the hanger should bea size larger than the pipe being supportedso the polypropylene pipe is free to move.(For example, if supporting 2" pipe, use 3"hangers, or when supporting 3" pipe, use4"hangers, etc.)Warnings: The use of uni-strut type hangers or anyhanger which relies on clamp tightness shouldnot be used.

2 Do not clamp a polypropylene pipe sys-tem tightly. It must be free to move.

Underground Installation of Orion Acid Waste SystemsThe trench as excavated for the pipe installationmust be free of loose stones, building materials oroutcroppings, and must provide minimum clear-ance around pipe of half the pipe diameter oneach side (horizontally) and one pipe diameterabove and below (vertically). The trench shall bebackfilled over the unexcavated base to a depth ofone pipe diameter with clean backfill. The backfillmaterial shall be free of stones and foreign matterand shall be capable of passing a No. 10 FITTINGS, Waste Piping SystemsAcid WAcid Waste Piping aste Piping Design DataDesign DataThe Piping shall be installed over this mate-rial and tested in accordance with applicableplumbing testing, initial backfilling must be care-fully accomplished, still using No.

The Piping should becapped off with an expandable plug at the endof the pipesection to be suggest that straight lengths of pipeshould be backfilled between the fittings being test-ed, prior to fill the pipe section with water, taking care toremove all trapped air in the Piping .

6 Use airrelease valves in any high spots in the system . Donot pressurize at this the pipe for at least one hour, to allow anequilibrium temperature to be check the system for leaks. If clear, checkfor and remove any remaining air from the the system to a suggested maximum of10 feet head by means of a standard 10 footstanding water test using a 10-foot vertical riser, ora low pressure hand the line at 10 feet of head pressure for aperiod of up to 8 hours, during which time thewater level should not change, (standing watertest) or the pressure gauge reading should notchange (hand pump test).Acid Waste Piping SystemsORION FITTINGS, INC. 47 Mechanical CouplingsPartMaterialTypeStandardSize,"G alvanic ReactionOuter bandStainless steelAISI 304-2 BASTM A240 Bolt barStainless steelAISI 304-2 BASTM A240 Bolt*Carbon steel Cadmium plated with Grade 85/16-18x1 dichromate coating Nut*Carbon steel Cadmium plated with 5/16-18 dichromate coating Washers*Carbon steel Cadmium plated withdichromate coating 5/16 WeldingStainless steelAutomatic MIG Basically nilwith Tri-MixCoupling body: Made from thermoplastic resin.

Inthis event, inspect for joint leaks. If none are found,check for trapped air - this air must be removed prior tocontinuing the joints are found to be leaking, the system must be fullydrained and the joints repaired.)))

It should not be necessary to cut out joints,unless the joint haspreviously been overheated, contaminated, fractured orvery badly made in the first place. Where joints have tobe cut out and replaced, the procedures for field cuts andjoint installation detailed in this manual should be the 10 feet head test after repairing any leaking joints, following the procedure described : Tanks should not be pressure :This system was designed for acid Waste of a gravitynature. Some low-pressure applications are possible, butshould be checked with factory engineering departmentbefore specification or installation.
