SUPREME Spool Type Styles 150, 200 and 200XL Ruber Expansion Joints

Unaflex "Supreme" Arch-type Expansion Joints are the WORKHORSE of our line. The arch design is the key that furnishes the flexibility required. Basic styles available in single, multiple or wide arch construction are: Style 150 for pressure and vacuum, Style 200 for Heavy Duty pressure and vacuum, and Style 200XL for very high pressure service. Expansion Joints that handle up to 500 ?F are available. Basic construction consists of tube, flange, carcass, internal steel reinforcements, cover and steel retaining rings. Unaflex Expansion Joints can be made with filled arches, multiple arches, Teflon (FEP) lined, sleeve ends, without arch, tapered (eccentric or concentric), offset, with enlarged arches and with special tube compounds for air, gas, oil, petroleum products, acids, slurries and chemicals of many kinds. Fire Retardant construction to ASTM F1123 specifications and readily available with complete testing and certification. All Supreme Expansion Joint constructions conform to U.S. Coast Guard requirements.

CONSTRUCTION DETAILS
1. TUBE - The tube is a single piece of leak proof lining extending flange-to-flange. It can be furnished in natural rubber, neoprene, Chorobutyl, Hypalon, Viton, Nitrile or other compounds as desired. All of our rubber compounds are specifically formulated to provide maximum sound and heat insulation as well as abrasion resistance.	5. FLANGES - Flanges are full-faced and made an integral part of the joint o insure a tight reliable seal. No gaskets are necessary. They are drilled to conform to the bolt holes of the companion metal flanges of the pipe line.
2. CARCASS - This is a strong, bias-ply construction, high-strength woven polyester reinforcing fabric between the tube and cover. The fabric will not rot or mildew and is thoroughly impregnated with special friction compound to give maximum adhesion under pressure, vacuum and stress conditions.	6. STEEL RETAINING RINGS - Steel retaining rings are made of flat-rolled steel, split, beveled and plated, and are required for installation.
3. STEEL REINFORCEMENT - These are the chemically treated solid-round, endless steel rings embedded in the carcass (with Unaflex proprietary method to prevent ring migration) giving maximum strength to the expansion joint while under pressure or vacuum service. Round rings, as opposed to square or rectangular rings, are used so there will be no sharp edges which could cut into the reinforcing carcass while flexing causing premature wear to the expansion joint.	7. HAND WRAPPED FINISH - Hand wrapping the finish (although more time consuming in construction) insures individual attention so that maximum pressure for curing has been obtained.
4. COVER - This is the exterior surface of the expansion joint, compounded of fire-retardant neoprene to withstand aging, cracking and corrosion. To further protect the exterior of the expansion joint, and to help resist acid and ozone attach, a special coating of yellow hypalo9n paint is applies.

Style 150 - For Pressure/Vacuum service
Style 189 - For High Temp and Low Spring rate, pressure limited to 25 Psi.
Style 200 - For Heavy Duty High Pressure/Vacuum service
Style 200 XL - For very high pressures. Consult Hosexpress for construction details.
Style 1000 - Wide arch offers more movement. Hand wrapped build process offers a large variety of construction variations.
Style 1100 - Wide arch offers more movement. Molded design keeps cost low.

SUGGESTIONS FOR INSTALLATION AND MAINTENANCE

Clean all foreign matter and remove burrs or sharp edges from flanges.
All pipe lines should be properly supported, so that the expansion joints do not carry the pipe load.
Remove burrs or sharp edges from flanges.
Do not install joints on raised face flanges of more than 1/16"
All pipes are to lined up accurately before installing expansion joints. Offset joints should be installed where misalignment is greater than the lateral movement allowed by joint construction.
Paint flange face with mixture of ordinary graphite mixed with enough glycerine to form a thin past. This will assist removal if it should become necessary.
Bolts should be on the inside of the joint flange. Metal washer must be placed at the facing of the split retaining rings.
Bolts should be tightened by alternating around the flange and all tightened equally.
Slight gouges or abraded areas caused by tools or bolts during installation should be sealed with rubber cement and painted to prevent deterioration of the carcass.
Bolt tightness should be checked one week after going on stream and checked periodically thereafter.
Joints installed outdoors should have a neoprene cover. All joints should be painted with Unaflex Hypalon paint.
All joints should be painted Unaflex Hypalon paint once a year.
If system is not anchored to insure against movement beyond maximum stated limits control units must be used.
