Dear Mr. Becherer:
This letter is in response to your June 10, 2019, email requesting clarification of the Hazardous
Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to tank car manway nozzles.
Specifically, you ask for clarification on the materials of construction requirements for manway
nozzles in “general service cars” (i.e., non-pressure tank cars). You note that in accordance with
§ 179.200-7(b), ASTM A 537 is not a listed material for construction of manway nozzles though,
as you note, it has similar properties as ASTM A 516, which is a listed material.
We have paraphrased and answered your questions as follows:
Q1. You ask whether this is an oversight based on the similarities between the properties of
both materials of construction.
A1. The answer is no. In accordance with § 179.200-7(b), ASTM A 537 is not a listed carbon
steel material of construction for manway nozzles in non-pressure tank cars.
Q2. You mention that ASTM A 537 has better elongation and yield strengths than ASTM A
516. You also provide designs for manway nozzles for tank cars constructed of ASTM A
537 and ask whether these may be used for non-pressure tank car specifications.
A2. The answer is no. Since ASTM A 537 is not an authorized material under § 179.200-
7(b), a special permit would be required to authorize use of this material. Section 179.4
provides the requirements for changes in specifications for tank cars by AAR Tank Car
Committee approval or special permit. To apply for a special permit, please submit an
application to the Associate Administrator for Hazardous Materials Safety in
conformance with the requirements prescribed in 49 CFR Part 107, Subpart B. You may

obtain information on the special permit application process from our website at
https://www.phmsa.dot.gov/approvals-and-permits/hazmat/hazardous-materials-
approvals-and-permits-overview, or by calling PHMSA’s Approvals and Permits
Division at (202) 366-4511.
I hope this information is helpful. Please contact us if we can be of further assistance.
Sincerely,
Dirk Der Kinderen
Chief, Standards Development Branch

Please log for response and have the drafter assigned work with Leonard - if we can expedite this
that would be great.
Thanks

Subject: FWD: Re: Manway Nozzle Material Question
Importance: High
Mr. Majors,
I was wondering if I could get your direct interpretation on current Manway Nozzles, and the material
they are made of for General Service Cars.
In MSRP M-1002, Appendix M, Table M.10.1 (snapshot attached), ASTM A537 is listed as being an
1

<<<PAGE 4>>>

approved material for Tanks, which would now include any Nozzles, under the new definition of a
tank.
When looking at 179.100-7 for Pressure Cars, ASTM A537 is an approved material, but in 179.200-7
for General Service Cars ASTM A537 is not listed as an approved material.
My question is, do you think this was an oversite for when the definition of a tank changed, and that
179.200-7 should read much like 179.100-7 to include A537 as an approved material?
I know there were thousands of General Service cars built with various nozzle materials used,
including A537, for Nozzles before the definition changed. So it would seem to me that A537 would
still be an acceptable nozzle material today.
So with that in mind, would you consider the attached drawing TRQ-2018-0927-10, acceptable by
having Item #2 listed as ASTM A537 material, and knowing it will be applied to a General Service
car?
As an example, if you look at the attached drawing of the 30143 gallon tank, the Nozzle "Neck" used
to make Item #4 and Item #6 is made from A519 Seamless Pipe/Tubing back in the day. As you may
know, a lot of these cars are being retrofitted to become DOT117R's currently.
Leonard, so my big concern is, we have an order going on now where our customer wants a Carbon
Steel extension per the TRQ-2018-0927-10 assembly attached, and the material chosen was
A537. Should we tell the factory to discontinue applying A537 and start using A516-70, or do you
think we are OK to continue with A537? As you see can see from the attached examples, the Nozzle
neck/rings were made of A53 and A519 in the past. The properties of A537 is very similar to A516-70
but with better Elongation and Yeild strengths, so I can't see why it wouldn't be acceptable.
Mr. Larry Strouse and Mr. Ken Dorsey seem to agree with me, but they had asked me to Consult with
you for your direction and/or approval.
Thanks in advance for your time with this matter.
