The hydrogen valve H29 ball-valve series is designed and tested for high cycle use in fueling, . aluminum, stainless steel, coatings such as SPECTRA-SEAL and SilcoNert) have an influence on the stability of individual contaminations and thus on the final analysis result [33,34]. materials that will never achieve DOE system targets Requirements for fuel Based upon Engineering Analysis Required: Liquid before and after hydrogen release >10 Wt% H 2 Maximum liquid range Thermal stability at 50 C Compatible with hydrazine regen Low cost In the past it was commonly specified for applications requiring chromium-molybdenum steels. can also permeate directly through materials used for natural gas distribution faster than methane. Blending hydrogen into the existing natural gas pipeline network appears to be a strategy for storing and delivering renewable energy to markets. During the expansion process, some gaseous low temperature hydrogen is recycled to provide additional cooling to the upstream gas. The preferred material for high pressure hydrogen service parts is austenitic (300 series) stainless steel. All nonmetallic materials in contact with hydrogen gas shall be reviewed for hydrogen embrittlement resistance at service conditions. Fuel Cell catalysts are normally porous and rough in texture in order to provide more surface area to the reactants oxygen and hydrogen. and valve materials that are incompatible with the flowing medium. content Volume Increment of Rubber Materials originated from Hydrogen (H2) ball valves specifications Sizes DN6 (1/4") - DN100 (4") Pressure rating up to 1000 bar (14500 psi) Body material 1.4571 / AISI316Ti, others on request Temperature range -40C / +150C Actuation manual automatic (pneumatic, electric or hydraulic) Connections DIN ISO 228 Female thread ANSI B1.20.1 NPT Female thread others on request Valve material - Hydrogen ICE2.

The N Series range of manual stop valves are a non-rising stem construction, suitable for a wide range of Industrial compressed gases, including Hydrogen. Proper selection of . Decades of valve experience in the petroleum sector with valves in high temperature and high-pressure hydrogen applications have proven that valves in that service often need tougher than normal pressure tests and sometimes even additional volumetric inspections such as radiography to ensure their soundness. Type I hydrogen tanks are made up entirely of metal and consist of a metallic liner only with the neck part and an optional end plug shown above. Hydrogen embrittlement, also called hydrogen stress cracking or hydrogen induced cracking, is a condition of low ductility in metals resulting from the absorption of hydrogen. [1] Material [ edit] Valves used in industrial hydrogen and oxygen applications, such as petrochemical processes, are often made of inconel . 90MPa,100 C 20 cycles . Assuming the exit temperature of the hydrogen doesn't drop below -41C due to material or . This material offers a cost effective solution with superior performance, operating across a wide temperature and pressure range.

Hydrogen valves and pressure regulators for fuel cell systems Valves are required in fuel cell systems to supply the gaseous fuel (generally natural gas or hydrogen) at the inlet side and to purge the condensate at the outlet side of the device. Hydrogen Embrittlement The effect of hydrogen on material behaviour, on its physical properties, is a fact. For example, some austenitic stainless steel valves have stems that are made from martensitic stainless steel. Our foundry is a reliable valve parts manufacturer and supplier for valve clients all over the world. Adding Hydrogen to the natural gas requires considerat ions regarding combustion systems, as well as the impact on compressors and pipeline hydraulics. 10mm .

We have engineered our high pressure valve stems, packing and associated soft goods to meet the unique requirements of hydrogen. different valve material corrosion charts. The tank and the used materials have a significant influence on the composition of the hydrogen to be analyzed. Reliable shut-off valves, the right material selection as well as standardised pressure tests help users to increase the operational safety in existing and new hydrogen application areas. Our valves deliver superior performance in low-pressure electrolyzers as well as in those that are subject to high temperatures reaching up to 700C. Vespel, with low hydrogen permeation, is the material of choice for: Safety/shut-off valves Pressure control valves Purge/drain valves There is no outer wrapping and the construction and manufacture of this type of tank is fairly simple and therefore also comparatively low in cost. (Austenitic stainless steel is generally considered acceptable for hydrogen service, whereas martensitic stainless steel is not.) METAL-SEATED BALL VALVES Other than our own chart, these are the best two charts we could find and their benefit is that they specifically relate to body and trim materials used in valve construction and they cover some material types and media types not listed in our chart. Pressure range up to 15.000 psi (1.050 bar).
