G 409 Technical Information - Guideline 09/2020 -pdf-file-
38,35 €*
This DVGW Guideline G 409 applies to the conversion of steel
gas pipelines for design pressures of more than 16 bar with welded joints for
the transmission of gases of the 2nd gas family as specified by DVGW Code of
Practice G 260 to hydrogen with at least 98 % by volume (in accordance with
standard ISO 14687 of Groups A or D). The design pressure DP of the pipeline
remains unaffected.
Details on the gas quality of the hydrogen meant for transportation
will be included in DVGW Code of Practice G 260 in the near future. After the
revised Code of Practice G 260 has been passed into force, it shall be the
preferred standard rule for consultation on matters of hydrogen gas quality.
Other installation components such as valves, pig traps,
regulating stations do not fall under this Guide-line’s purview and must be
examined and evaluated separately.
A pipeline that transports even small amounts of hydrogen
shall, if necessary, already be evaluated sepa-rately. For such cases, this
Guideline’s specifications may be applied mutatis mutandis.
For gas pipelines made of other material, steel pipes with
detachable joints, or gas pipelines with a design pressure lower than 16 bar,
this Guideline’s specifications may be applied mutatis mutandis.
When planning the conversion of a gas pipeline that
transports gases that do not correspond with the specifications of DVGW Code of
Practice G 260, this Guideline may be applied mutatis mutandis if the specific
characteristics of these gases are taken into account and other applicable
regulations, if they exist, are adhered to.
G 493-2 Technical Rule - Standard 11/2019 -PDF-File-
59,59 €*
This standard G 493-2 encompasses personal and professional
requirements for companies providing maintenance for gas plants and

injection and refeeding plants as specified by DVGW G 265-2 or hydrogen
injection plants as specified by DVGW G 265-4 (M).Companies which, within the
context of comprehensive plant management, either as original operators or as
contractors, are responsible for the maintenance of energy plants, and possess
the required personal qualification and organization according to DVGW G 1000
(A), may conduct the maintenance of gas plants without certification as defined
by this standard within the network which they have the abovementioned
responsibility for. The prerequisite for the maintenance without certification
as mentioned above is that the expert and tech-nical conditions detailed in
this standard are met by the company’s own workforce or by service providers
with a TSM certification or other corresponding certifications. The company
shall appoint the experts re-sponsible for maintenance in writing. The
fulfilment of these conditions can be verified e.g. during a TSM review
according to DVGW G 1000 (A).

well as DIN EN 16726 and all gases used for the
supply
via pipeline system of the general public and
other consumers with a comparable level of
safety.
When using sulfur-containing odorants, the fact
shall be taken into account that the entailed
increase of
the sulfur content in the gas is undesirable for
some applications, such as its use as basic
material in the
chemical industry.
Industrial companies using natural gas
exclusively on company premises can forego
odorization if the
operator utilizes other measures to maintain the
industrial gas plant or system’s safety.
When switching from one odorant to another,
special attention shall be paid to Section 9.
The calibration of measuring devices for odorant
control requires test gases which are detailed in
Section
10.

This Code of Practice G 402 has been elaborated by the ?G 401? project group within the Technical Committee on ?Gas distribution?. It shall serve as a basis for the collection and evaluation of data to devise mainte‑nance strategies for gas distribution systems. Maintenance comprises inspection as well as service and repair activities. The respective DVGW Codes of Practice define the fundamental principles applying to inspection and service activities. This Code of Practice G 402 focuses on the collection and evaluation of data that form the main basis for repair planning. The requirement for gas distribution systems to be permanently kept in a condition guaranteeing their technical safety and reliability necessitates timely and ongoing maintenance and service activities. These activities shall be planned in advance. Maintenance strategies shall be integrated into corporate processes, the collection of major grid data being a prerequisite for introducing such strategies. Beyond this, condition‑based maintenance requires ascertaining and evaluating grid conditions by means of adequate systems. This Code of Practice describes the fundamental procedure for ascertaining, collecting and evaluating maintenance‑relevant data and offers examples illustrating how to prepare and evaluate them. This Code of Practice does not specify a standard data collection procedure for creating a planning concept in conformance with href= https://shop.wvgw.de/508331 >here.
