is legislative decree 37/2008 applicable in industry?

[YWH]

Good morning.

my client, among the most meticulous and attentive to regulations and anything else, asks me to certify according to Legislative Decree 37/2008 a very trivial modification of a piping carried by us, we simply varied the path of a dn50 tube that transports nitrogen to pressure of 2bar.
I pray that I did not know in detail this decree I went to read, and to article 1 (copio and incollo:mixed:
)
"Art. 1. scope of application
1. this decree applies to plants placed at the service of buildings,
regardless of destination of use, placed within the same or
of the relative relevance. if the system is connected to distribution networks
applies from the delivery point of the supply.
2. the plants referred to in paragraph 1 are classified as follows:
a) production, processing, transport, distribution,
use of electricity, waste protection systems
atmospheric and automation plants for doors, gates and gates
barriers;
b) radio and television systems, antennas and electronic systems in general;
c) heating, air conditioning, air conditioning and heating systems
Refrigeration of any kind or species, including evacuation works
of combustion products and condensates, ventilation and ventilation
of the premises;
d) water and sanitary facilities of any kind or species;
(c) installations for the distribution and use of gas of any kind,
including evacuation of combustion and ventilation products
and ventilation of the premises;
f) lifting plants of persons or things by means of lifts, of
whirlpools, escalators and similar;
g) fire protection systems.
3. plants or plant parts that are subject to safety requirements
prescribed in implementation of Community legislation, i.e. legislation
specific, shall not be governed by the provisions of this
decree. "
My opinion is that it is not applicable and that it is much more relevant to Article 3 of the ped legislation.
a thank you in advance to anyone who will give me related information

bye, to start:
you are talking about the dm 37/2008 not of the d.lgs! attention to the English!
I do not know very well the aspects you mention but it seems to me that the dm is applicable given the definition of Article 1.
It would be to understand what you're talking about, what plant.
Maybe you fall into the ped, but I don't know if in art. 3.

Thank you gerod,
You are right is a ministerial and non-legislative decree, my mistake.
However, this tube is placed in a plant producing technical gases (a part of the plant is air fractionation, while a part produces hydrogen by methane reforming) and transports the flux nitrogen of safety valve discharges.
the tube starts from the storage tank of the liquid nitrogen, and after being passed into a pressure reducer and a heat exchanger, reaches the safety valves, then what "draws" on the air fractionation system is put in circulation, while what comes from the production of hydrogen, is burned (I believe, but I am not 100% sure) in a candle.
we intervened upstream of pressure reducer and therefore exchanger on a stretch that had already 2 bar of pressure and room temperature
It is precisely the definition of Article 1 that leaves me perplexed, as it speaks of "plants placed at the service of buildings", while in the specific case (in my opinion) it is not so, unless "regardless of the use destination" refers to the plant and not to the building.

the fact that elapses in art.3 of the ped, if true (verification), means only that the marking procedure is not necessary (I think you are talking about art.3 paragraph 3). in such case your equipment must be made to the rule of art (how? ).
then you have to see if you are in the field of dm329/04 regarding the use of your equipment (if you do, the user must perform a whole series of administrative activities to be able to exercise it).
the dm37/08 is then something more specific for Italy (in addition it means that in Italy if you want to build it and manage it you can not stop with the ped and dm329/04 but you must respect also 37).
It does not seem to me that the demands of 37 are in contrast with the others of ped and 329
Hi.

Thanks chicken,
the pipe falls in art.3 paragraph 3 (I have a software that calculates it, but for safety I also asked the iis), so I built my pipe and drafted a technical file where I attached a short technical report, the certificates of the materials used (valves, flanges, tubes), the welding book, etc.
the dm329/04 I do not know him well, now I look for him and, as soon as I find the time, I read it.
my doubt about dm37/08 is that it speaks of plants placed at the service of buildings, and in my case it is not so, at least in my way to see.

 

[YWH]

reading the dm329/04, I see that
art. Excluding
1. This Regulation shall not apply to the products listed in Article 1, paragraph 3 of Legislative Decree No 93/2000, subject to the equipment referred to in Article 1, letter c), and to the following objects:
...... .
bb) pipes with dn less than or equal to 80;
.... .
So my case doesn't fit in.
summing up:
according to the ped rule are in art.3 paragraph 3, and therefore I made my handkerchief, with all attachments, as I always do in more "heavy" cases
the dm37/08 speaks of plants placed in service of the buildings, and in my opinion it is not applicable since the plant is not at the service of a building.
dm329/04 excludes pipes with dn<= 80.
Maybe I fell into a legislative hole.
