Dresser Flange Adapters, Dismantling and Expansion Joints

Three ways to connect and adjust pipe at flanged equipment and along long runs: the Style 128 flange adapter, Style 131 dismantling joint and Style 63 expansion joint.

This collection groups the Dresser products that sit between pipe and flanged equipment, or take up movement along a line. The Style 128 flange adapter joins plain-end pipe to a flange without welding. The Style 131 dismantling joint adjusts in length so a valve, pump or meter can be removed without cutting the line. The Style 63 expansion joint absorbs concentrated pipe movement on long or exposed runs.

Style 128 and 131 are listed by size and Dresser part number. Style 63 is engineered to order and quoted per job. Call 1-888.510.4036 or email sales@watermainsupply.com. Genuine Dresser equipment, factory-new in original packaging — sold and supported by Watermain Supply, an independent industrial supplier.

Will It Work for Your Job?

Pressure

Style 128 and Style 131 are rated 150 PSI with AWWA C207 Class D flanges; other flanges are available for higher pressures. Style 63 is built to the pressure and temperature of the job.

Restraint

None of the three restrains the pipe on its own. Style 131 can be ordered with tie rods; anchor the line at the 128 and 63 as Dresser requires.

Pipe

Style 128 fits steel, cast and ductile iron pipe. Style 131 bolts between flanges. Style 63 is built for steel lines.

Quick rule: Joining plain-end pipe to a flange, use the Style 128. Installing a valve, pump or meter you will someday pull, use the Style 131. Taking up thermal or repeated movement too large for a coupling, use the Style 63.

Sizing and Best Practices

Flange adapters

Measure the pipe OD with a pi tape and confirm the mating flange drilling before ordering a Style 128.

Dismantling joints

Order the Style 131 by nominal size and flange; check the closed and open lengths against the gap at the equipment. Specify tie rods where thrust could pull the joint open.

Expansion joints

Dresser quotes each Style 63 from the job details: pipe type and OD, Type 1 or Type 3, single or double end, service, maximum pressure, temperature range, movement per joint, cycling, end preparation and how the line is supported. A sketch helps.

Need help? Send the pipe OD and material to sales@watermainsupply.com and we confirm the Dresser part number.

Frequently Asked Questions

What warranty applies?

12 months from the date of purchase under Dresser published warranty terms.

What is the difference between a flange adapter and a dismantling joint?

A flange adapter joins plain-end pipe to a flange. A dismantling joint is flanged on both ends and adjusts in length so equipment between flanges can be removed.

What pressure are the Style 128 and Style 131 rated for?

Both are rated 150 PSI with AWWA C207 Class D flanges. Other flanges are available for higher pressures.

Do these joints restrain the pipe?

No. Anchor the line, or order the Style 131 with tie rods where thrust acts on the joint.

How much movement does a Style 63 take?

Single-end joints take up to 10 in of concentrated movement as standard; more is available on request.

Why can I not buy the Style 63 online?

Dresser engineers each joint for its installation. Send us the job details and we return a firm quote.

When do I need an expansion joint instead of a coupling?

Dresser couplings 10.75 in OD and larger take up to 3/8 in of movement per joint. Use a Style 63 for repeated movement or more than that.

Can I get a factory submittal?

Yes. Email sales@watermainsupply.com with the part numbers.
