EXPANSION JOINTS MX EXTERNALLY PRESSURIZED
To insure pressure tight sealing, raised face slip on flanges in full compliance with ANSI B 16.5 are standard. Flange material is either ASTM A-105 (Forged) or ASTM A-36 (Plate). Lap joint flanges can be furnished as an option to permit easy alignment of bolt holes. Alloy ends are available where additional corrosion resistance may be required.
THE MX DESIGN ADVANTAGE
FEATURES
1 FLANGES
Designed for full line pressure to insure in the unlikely event of bellows failure media will not escape radially outward.
2 COVER
Microflex’s MX expansion joints are designed with an uncompromising standard of quality for years of mainte-nance free operation in distribution pipelines conveying liquids or gases.
Provides a convenient location for installing a steam trap. May also be used to drain liquids when pipeline is shut down.
3 DRAIN
Bases are standard on double designs and optional on single designs. Base is designed as a support or intermediate anchor.
4 BASE
Internal and external guide rings are welded to inner end of pipe and outer cover. They are designed to provide accurate guiding of bellows as the pipeline expands or contracts. This insures bellows will not be scored or subject to movement for which it was not designed to accommodate.
5 GUIDES
Single or multiple bellows are precision formed from cylinders of deep draw quality annealed sheet conforming to ASTM specifications - Type 304 is standard and suitable for most chloride free applications such as steam, condesate, oil or chill water. Where chlorides may be present, Inconel 600 bellows should be specified.
6 BELLOWS
Carbon steel pipe liner is standard and designed to prevent bellows fatigue failure due to flow induced vibration. Liner is not affected by flow direction, therefore the MX may be used in pipe systems that have reverse flow conditions. Where additional corrosion resistance is required, liner and all other wetted surfaces may be furnished with alloy construction.

THE MX PERFORMANCE ADVANTAGEMicroflex’s MX expansion joints out-perform all other methods of thermal expansion compen-sation and in most cases with lower installed cost.
WARRANTYMicroflex’s MX expansion joints are warranted to be free from defects in material and workmanship for a period of 5 years from date of shipment. In addition they are warranted to provide 5 years of leak free and 5 years of maintenance free operation when installed, anchored, and guided in accordance with Microflex’s instructions, in a piping system conveying liquids or gases that are non corrosive to the bellows, end connection and housing materials of construction.
Buyers exclusive remedy shall be limited to repair or replace-ment for any product which is determined to be defective by
Microflex upon it’s return to the factory. Microflex will not allow any charge for labor, shipping expense or damage of any kind, direct or indirect attributed to defective material, and by accepting material buyer will assume all liability for any damages which may result from its use or misuse.
Some manufacturers of bellows expansion joints depend upon the use of bolted on external reinforcing, or equalizing rings, when design pressures exceed 50 PSIG. These rings are required since the bellows by itself is not capable of withstand-ing 300 PSIG or even 150 PSIG, as commonly encountered in distribution piping systems. Because these equalizing rings can be made from common gray cast iron they are prone to fracture failure if subjected to a sudden thermal shock such as spraying cold water on a hot equalizing ring.
An equalizing ring failure could result in bellows rupture. In addition, since equalizing expansion joints do not haveInternal liners as part of their internal design, flow induced
vibration can cause this rough textured cast equalizing rings to rub through or locally thin the bellows wall.
Microflex’s MX expansion joints have bellows that are designed to withstand operating pressure without the need of any external reinforcing or equalizing rings. Each MX design has been computer verified to comply with the rigid design criteria of the 5th edition of the of the EJMA standards. Internal liner and external cover of pipe wall thickness are an inherent part of the MX design. The MX is literally “sledge hammer” tough. The initial cost of an MX can be significantly lower than an equalizing expansion joint with optional liner and cover.
THE MX ADVANTAGE OVER EQUALIZING EXPANSION JOINTS
Slip joints depend upon the resiliency of packing rings to effect a pressure tight seal. Exposed to the ravages of time, tempera-ture and slip movement even the so called “high performance” packings lose resilience and volume with inevitable leakage. Because of possible leakage, all slip joint manufacturers recommend periodic inspection of the installation to insure leaks are stopped before irreparable wire drawing of the packing or metal components occurs.
slip joints (vaults for underground pipelines) and the continual maintenance costs of inspection, adding packing and shut downs to change packing.
Microflex’s MX expansion joints are packless, hermetically sealed with all welded construction, therefore can be installed in remote locations without need for access vaults, inspection or maintenance, ever. In addition, the initial cost of an MX is 20%-50% less than a slip joint.
THE MX ADVANTAGE OVER SLIP JOINTS
Pipe loops are usually field fabricated from pipe elbows with a length of pipe between. It is the pipe between elbows, not the elbows themselves, that provide flexibility. Since pip, especially in larger diameters is very rigid, loops require many feet of pipe and space to compensate for even small amounts of thermal expansion. As an example to compensate for 4” of movement in a 12” sch 40 pipe a loop would have to be 8.5’ wide by 17’ high. The additional pipe and elbows results in greater heat
loss, increased pressure drop, and increased operating costs.
Microflex’s MX expansion joints are a straight through design with full bore internal pipe liner and cover, that when insulated will have no greater heat loss or pressure drop that the section of pipe it replaces. Although initial cost is comparable to a pipe loop, operating costs are less, and where space is at a premium the MX is the clear choice for economic savings.

MX DESIGN TYPE
TYPE MXSThe MX single design options include weld, flange or combination end types and comply with MIL E - 17813 E type IV style 1 & 2 (class 1 single).
TYPE MXDThe MX double design options include weld, flange or combination end types and comply with MIL E - 17813 E type IV style 1 & 2 (class 2 double).
Note: axial movement listed in chart is combined total of both bevels.

EXPANSION JOINTS MX EXTERNALLY PRESSURIZED
INSTALLATION INSTRUCTIONS Microflex’s MX expansion joints are designed to absorb axial movement only, and must therefore be installed in straight sections of pipelines, with properly designed anchors, guides, and supports. Figure 1-3 below illustrates proper installations. Methods for determining anchor loads are published in EJMA standards or available form Microflex on request.
Figure 1-1 shows the proper use of a single MX expansion joint to absorb axial pipe line expansion. Main anchors (MA) are located at changes in pipe direction. Only one expansion joint should be installed between anchors and preferably within four pipe diameters of an anchor. Pipe guides (G) are located in accordance with table below.
MX SINGLE
Figure 1-2 shows the proper use of a double MX expansion joint to absorb axial pipe line expansion. Main anchors (MA) are located at changes in pipe direction. The double MX expansion joint with intermediate anchor (IA) is located equal distance from main anchors. Pipe guides (G) are located in accordance with table below.
MX DOUBLE
Figure 1-3 shows the proper use of a three single MX expansion joints to absorb axial pipe line expansion with a branch connection. Main anchors (MA) are located at changes in pipe direction. Only one expansion joint should be installed between anchors and preferably within four pipe diameters of an anchor. Pipe guides (G) are located in accordance with table below.
MX SINGLE (x3)
To insure long maintenance free operation, pipe alignment guides must be installed as tabulated below.
