about marine plumbing and sprinkler design, a nice break from designing

office towers, schools, and hospitals. We are pleased to offer this rare

opportunity; you won’t want to miss this.

Let me close by saying; our sister society ASPE recently had a changing of

the guard and want to thank out going ASPE President Hershel Weiss for

doing an outstanding job. It has been a real pleasure to work side by

side with Hershel. I also look forward to working with ASPE’s newest

president Leon Perkolaj. Leon and I share a commitment to stand on the

shoulders of the previous accomplishments and continue to serve the

Plumbing and Fire Protection Engineers of NYC as best we can.

Please enjoy yourselves and take advantage of the wonderful food and

drinks here at Heartland.

Minutes of Meeting

ASSE/ASPE Technical Presentation Wednesday, September 2, 2009

Presenter:

Mr. Crosson made an excellent presentation entitled “Failure analysis and in service testing of plumbing pipe systems and

soldered connections”. During the presentation, numerous slides were shown of actual case studies and cross sections of

pipe detailing the type of corrosion and the number of years the pipe was in service and the type of failure. These slides

provided excellent examples of real world studies of the types of failures being discussed.

Mr. Crosson’s firm, Lucius Pitkin, is involved in

1) Non destructive testing

2) Metallurgical testing

3) Engineering analysis of

There are 3 basic modes of failures of plumbing systems.

1) Service related corrosion

2) Workmanship failures

3) A combination of above

The types of general corrosion are localized pitting, crevice corrosion, galvanic corrosion, graphitic corrosion (only in cast

iron) and dezincification.

Workmanship failures tend to be poor seems welds. They occur most commonly in threaded joints (improper insertion

depth) and in soldered joints (improper insertion depth and improper wetting of the surfaces).

Corrosion occurs in many different forms. It can occur as uniform corrosion over large interior surfaces of the pipe. This

appears as a mottled surface.

General corrosion can also appear as pitted surface. A slide was shown of a 100-year-old domestic hot water pipe

reflecting this type of corrosion.

Pitting corrosion tends to be localized throughout the pipe and occur at random locations.

Domestic water in general, is not as corrosive as condenser water. Condenser water is treated and is generally kept at a ph

of 7.5 to 8.5. It must be treated because it tends to pull in impurities while in service.

Corrosion tends to be accelerated in secondary, treated water applications. Slide was shown giving dramatic evidence of

this.

Contrary to common belief, copper is not corrosion resistant. Corrosion can occur where deposits happen. Stray DC

current can accelerate corrosion in copper pipes. AC current will not cause corrosion. Exterior corrosion can occur if pipe is

not installed properly.

Example was given of the copper patina on the Statue of Liberty, which acts as an actual barrier to further corrosion of the

copper surface.

Threaded joint corrosion was discussed. Corrosion that attacks a threaded joint area is worse than at a remote non-

threaded location in the pipe. This is because the threaded area thickness is already greatly reduced by the threads

themselves.

Mechanical Joint corrosion was discussed and it was shown that “cut” mechanical joints be much more effected than rolled

joints under corrosion. This is because “cut” joints have less material by definition…i.e. material removed to make cut,

hence area is thinner. Example slides shown of severe corrosion at cut joints.

Crevice corrosion is localized and occurs at crevices, corners, threaded connections and fraying surfaces. It is the result of

oxygen cells concentrating at those locations.

Galvanic corrosion occurs where dissimilar metals meet and is the result of an electrolytic reaction much like that in a

battery. It is an electromechanical cell at the anode. This can be eliminating through the use of a dielectric device

separating the dissimilar metals.

Zinc tends to be a very common location where galvanic corrosion is seen. A chart was shown showing the range of

common metals and the potential difference between them reflecting which metals can be in contact with each other and

which should not.

Graphitic corrosion occurs in cast iron only. The cast iron is actually transformed over time. It loses all strength and may

not be visible at all to the naked eye.

It occurs as layer type and plug type. Plug type tends to end up in catastrophic leak failures. Slides were shown of buried

cast iron pipe showing interior and exterior types of corrosion.

Dezincification corrosion occurs in brass only. It occurs in brass with over a 15% zinc content. Solution is to specify and use

brass that is called red brass defined as brass with less than 15% zinc content. Brass is a zinc/copper alloy. Dezincification

is dependent on how aggressive the water supply is and will not occur in all water supplies.

Soldered/brazed joint failure was reviewed in detail. It is very important that joints be inserted to their full depth to insure

a good soldered joint. The capillary space must be fully wetted to insure a good solder joint. And the surfaces must be

actually fused to insure a good joint.

Numerous slides were shown of poor soldered and brazed joint resulting in catastrophic leak failures and substantial

damage and liability claims.

Pre action sprinkler pipe was shown and that a dry system can actually have corrosion failures. This is most commonly

reflected after the hydro test if the pipe is not fully purged of all water. You can get a corrosion attack at the wet location

in the pipe system.

Inspection techniques were shown in great detail. These were liquid dye penetrant, ultrasonic, visual examination (both

standard and through video inside the pipe). The various inspection techniques were reviewed giving the pros and cons of

each and when and where each inspection technique should be applied.

Electrical for Plumbing and Fire Protection Systems

Part IV

By: G.T. DiPietro

Controls

It is undesirable to use high motor voltages for control circuits,

therefore a control circuit transformer is usually provided (it is also

possible to bring into the control cabinet enclosure a separate 120

volt lighting circuit, but this is not usually done).

For most equipment, where control circuits of each duplex or

triplex equipment are kept separate, a separate control circuit is

provided for each motor and its primary is connected to the power

feeder of that motor. Where control circuits for duplex or triplex

equipment are centralized and where electric alternators are used.

Such as for constant pressure booster systems, a single control

circuit transfer switch is provided with its primary connected to

both (two or three) feeders through an automatic transfer switch

(this enables the pumps to have power if one feeder fails).

It is desirable to equalize wear on duplex or triplex equipment.

This can be done manually or by the use of automatic alternators.

However, automatic alternators equalize the wear evenly and they

all wear out at the same time which is undesirable. A manual

transfer switch will equalize the wear but not so perfectly, due to

the irregularity of the operators. This may be preferred by the

client.

For duplex equipment a four (4) pole double throw transfer switch

is usually used. For triplex equipment either a six (6) pole or

three-way transfer switch of three (3) jack plugs and receptacles

can be used. If the third unit is for a future installation, the jack

plug setup must be used.

ASSE WANTS YOU!

ASSE wants your technical articles. With so many new young faces showing up at the ASSE/ASPE monthly

meetings, there appears to be a thirst for knowledge here that only a more seasoned veteran can provide.

Therefore, if any of you senior plumbing engineers can remember what it was like to gain the attention of a more

senior Plumbing Engineer to further your knowledge of plumbing engineering; this is your opportunity to give

back that knowledge

Your article on plumbing, fire suppression, and site civil engineering no matter how big or small would be greatly

appreciated by all.

Thanks for your support to our plumbing family!

ENGINEERING FORMULAS – PART IV

AVERAGE FLOW RATES

By: G.T. DiPietro To determine the average flow rates see the following example: Three (3) laundry machines will discharger at a flow of 50 GPM each and spill into a trench that is 1’-6” deep. The laundry consultants indicate a 4” drain in the trench. Determine if the trench drain size is adequate and size the horizontal pipe.

Q = 13.17D2 √H Q = Rate of Discharge (GPM) D = Diameter of outlet (IN) H = Mean vertical distance from water surface to outlet (FT)

First determine mean distance from the water surface to drain outlet.

1.5/2 = 0.75F.T Apply the information into the formula. Q = 13.17 (4)2 √0.75 Q = 13.17 (16) (0.87) Q = 183 GPM It appears the trench drain is adequate, however, the drain line from the trench must be capable of discharging the 150 GPM flow rate from the three (3) laundry machines simultaneously. What size should the horizontal drain pipe be? What would you do? Send your answers to [email protected].

FOR THOSE OF YOU WHO ARE ICC MEMBERS:

CALL TO ACTION

Mobilize to Defend IRC Fire Sprinkler Requirements

Mark Your Calendar for Wednesday, October 28th

The 2009-2012 International Residential Code (IRC) development cycle is now underway, and to our disappointment, the

National Association of Home Builders (NAHB) has submitted proposals to rescind home fire sprinkler requirements. This

misguided effort disregards the demonstrated value of sprinklers in saving lives and reducing human suffering associated with

residential fires. To protect the public and firefighters, we must once again stand tall by opposing these changes.

What can I do to help? 1) VOTE AGAINST THESE PROPOSALS, AND 2) SPREAD THE WORD.

NAHB’s proposals and others impacting fire- and life-safety (among them, proposals to require protection of lightweight

construction in residential occupancies), will be heard at the International Code Council’s (ICC) upcoming hearing in Baltimore,

MD, on Wednesday, October 28th. Your attendance and vote are critical to keeping fire sprinkler requirements in the IRC.

What’s required to vote? YOU MUST BECOME AN ICC MEMBER PRIOR TO OCTOBER 14TH (if you’re not already a member) and

you must attend the Baltimore hearing. Anyone with an interest in ICC codes can be a member (this includes fire fighters,

contractors, engineers, members of the public, etc.). It only takes a few minutes to sign up online. For more information, go to

www.IRCFireSprinkler.org/2009BaltimoreHearing.aspx).

Can I vote without going to Baltimore? NO, you must be present to vote (no proxies allowed).

Do I have to be a government official to vote? NO, at this hearing, any ICC member, regardless of membership category, may

vote.

Can ICC government agency members send more than the 4, 8 or 12 voting delegates allowed by their agency membership?

YES, additional employees (including firefighters) can join ICC for $35 as Associate Members, and these individuals will be

permitted to vote in Baltimore.

How important is the Baltimore vote? THE FUTURE OF RESIDENTIAL FIRE SAFETY IN AMERICA MAY WELL HINGE ON THIS VOTE.

Winning the Baltimore vote would largely assure that sprinklers will remain a requirement in the 2012 IRC. Losing the vote would

1) Almost certainly derail the progress that we've made in states that are moving towards requiring sprinklers in new homes

based on the 2009 codes, and 2) Place the IRC sprinkler requirements at risk of being removed from the 2012 code at ICC’s final

action hearing next year.

Fire- and life-safety advocates demonstrated their commitment to safe housing last year by making an unprecedented showing at

ICC’s final action hearing in Minneapolis. Minneapolis represented the successful culmination of a 30-year effort to have model

codes require fire sprinklers as a standard feature in all new homes. We must now ensure that this victory does not slip through

our fingers.

Home fire sprinklers represent the best chance that we have of striking at the heart of America's fire problem. Please come to

Baltimore and help us send a strong message to sprinkler opponents that America's Fire Service and others who support fire safe

homes will not yield on this issue.
