Unaflex "MATCHLESS" Expansion Joint Bellows are produced from fully annealed type 321 stainless steel sheet stock rolled into a tube and seam welded.  The latest technology in forming the corrugations of our bellows is employed.  Other alloys such as Inconel, Monel, Titanium and 316 stainless steel may be provided from our extensive inventory of raw materials.

	Type 44 (Fixed Flanges)
	Type 44 Ends are plate steel flanges conforming to ANSI dimensions welded directly to the integral ends of the bellows.  Stainless steel and other alloys are available when specified.
	Type 66 (Floating Flanges)
	Type 66 Ends are flat face plate flanges conforming to ANSI dimensions secured to the integral end of the bellows flared (Vanstoned) to retain the flanges.  This allows the use of carbon steel flanges when the only wetted parts will be the stainless steel of the bellows.  Also permits easy bolt hole alignment.
	Type 22 (Welding Nipples)
	Type 22 Ends are coarbon steel weldoing nipples with ANSI standard bevel.  Schedule 40 pipe size is used through 12" diameters.  1/4" wall thickness for sizes over 12" unless otherwise specified.

	Definition of Movement		"MATCHLESS" Bellows-Type Expansion Joint Recommended Installation Instructions
	Explanation of Axial Movement, Lateral Movement, and Angular Movements. Also, Anchoring and Guiding, and Cycle Life.		Metal Bellows Expansion Joints have been designed to absorb a specified amount of movement by flexing of the thin-gauge convolutions.  If proper care is not taken during installation, it may reduce the cycle life and the pressure capacity of the expansion joints which could result in an early failure.

	Unaflex Matchless Metal Bellows Expansion Joints		Unaflex Universal Tied Expansion Joints
	Metal expansion joints are primarily used to absorb movements in piping caused by thermal changes......		Unaflex Universal Tied Expansion Joints are capable of absorbing greater lateral movements than standard bellows type expansion joints.
	Unaflex Externally Pressurized Bellows Expansion Joints		Series 5000 BPC Bellows Pump Connector Assemblies
	Type EXS Single and Type EXD Double.  All units can be provided with pipe nipples, along with anchor bases, drains and other accessories.		Metal Bellows Pump Connector Dimensions, and Standard Operating Specifications.
	"MATCHLESS" Non-Standard Dual Unit		Pressure-Balanced Unit
	Dual Expansion Joints are often used where Axal movement is greater than can be absorbed by a single Expansion Joint.		"Matchless" pressure balanced expansion joints are designed to absorb axial movement and/or lateral deflection where pressure thrust loading is considered excessive or objectionable to the system.
	Liners and Covers		"TUBE-FLEX" Engine Exhaust Expansion Joints
	Liners and Covers are used to provide additional protection to the thin wall bellows element of the expansion joint.  Dents or other damage to the bellows will materially affect the performance of an expansion joint and a cover should be used where conditions warrant this additional protection.		Unaflex "TUBE-FLEX" Series 7000 Stainless Steel Engine exhaust Expansion Joints are manufactured from a thin gauge stainless steel tube.  This tubular body is formed into corrugations forming a bellows providing a highly flexible and durable connector for the extremes of exhausting engine gases.
	U-100 Expansion Joints		High-Pressure Expansion Compensators
	Unaflex "TUBE-FLEX" Style U-100 Expansion Joints can absorb longitudinal and lateral movement in one cycle.  Opposite ends of the joint can move laterally in opposite directions to complete and expansion cycle.		Designed to eliminate pipe "networks" and to save space.  Their all metal construction allows use in high-pressure steam and water riser applications with pressures tested to 225 psi for recommended maximum operating pressure of 150 psi.
	"MASTER" Flexible Metal Pump Connectors		"INTER-FLEX" Interlocked Flexible Metal Tubing
	Unaflex "MASTER" Flexible Metal Pump Connectors are designed with a flexible core of corrugated tin bronze (98 3/4% copper, 1 1/4% tin), or corrugated-type 321 stainless steel tubing under the braid.		This Flexible Metal Tubing is constructed of a variety of metals (galvanized or bright steel, aluminum, brass, bronze or stainless steel, used in applications for Ventilator, blower hose, hot air, fume and fresh air ducts, shielding electrical wiring, engine exhaust.......and more.....
