Furnaces was established in 1946 and has been known for state of the art design and manufacturing of all types of air, hydrogen and inert atmosphere electric furnaces . Though many of our furnaces are of standard design and construction, CM has specialized in fur-naces for a variety of applications or to update standard equipment to
High-temperature hydrogen attack of carbon of the test environment to the desired pressure. The hydrogen was of laboratory grade that the furnace, the specimens were air-cooled and

Pressure transmitters are used to measure the pressure or level of industrial liquids and gases. The output is transmitted to a control system. Accurate and stable process measurements ensure the safe, reliable, and profitable operation of your plant.

• Understand the explosive nature of hydrogen gas at atmospheric pressure and in near vacuum conditions Project Goals • Determine minimal levels of energy to ignite hydrogen / air mixtures • Determine if Nitrogen or Argon gas will act as a dilutant for hydrogen / air reactions • Develop recommendations for the safe use of
What is Brazing? Brazing joins metals by flowing a thin capillary thickness layer of non-ferrous filler metal into the space between them. Bonding results from the intimate contact produced by dissolution of a small amount of base metal into the molten filler metal, without fusion of the base metal.
Measurement of Hydrogen H 2. For the measurement of hydrogen concentration in gases, the high thermal conductivity of hydrogen can be used. Hydrogen conducts heat much better than air (factor 7), nitrogen and most other gases. Only Helium has also a similar high heat conductivity (6 times higher than air).
produce hydrogen. Hydrogen can be used as fuel to power internal combustion engines or fuel cells, or as an energy carrier. Hydrogen has been used as an industrial chemical for more than a century. The Haber process for producing ammonia was developed in 1909 (Austin 1984), and
KSL-1700X-H4 is UL standard large box furnace designed for material synthesis under hydrogen or inert gas atmosphere up to 1700 ºC. The furnace consists of high quality alumina fiber bricks and three side heating bu Mo alloy coil with a heating chamber of 20"x 20"x20", as well as a vacuum-sealed steel case with water cooling jacket and automatic H2 burning system.
University of Hawaii fined $115,500 for lab explosion the potential for explosion from a ungrounded tank with a pressure gauge not rated as intrinsically safe would have been greatly reduced
for which it was not designed. It is better to mark the low pressure (outlet) gauge at the desired pressure setting with a laboratory marker and then back out the pressure adjusting knob of the regulator to stop the ﬂow. This procedure will not affect the manual or electronic valve settings in the instrument.
trace quantities in the atmosphere. In the XVIIIth century, Lavoisier suggested to re-name the gas previously refer-red to as "flammable air" by Cavendish referring to its combustive nature as "hydrogen" which literally means "that produces water". The main physico-chemical properties of hydrogen give rise to specific risks
In order to match the test requirements for the introduction of hydrogen, the tube furnace is equipped with a manual ignition device at the right end of the furnace tube to ensure the safety of the test; a vacuum gauge and an air pressure gauge are arranged on the left side of the furnace tube to control the vacuum and atmosphere inside the
Is it safe to anneal a material in a hydrogen atmosphere given the fact that hydrogen is highly combustible? Due to there is no oxigen in the furnace the hydrogen can not combust and only
positive pressure when the door is closed and sealed. As a safety feature, absence of this pressure prevents admission of Hydrogen and inhibits the application of heater power. An exhaust gas burnoff column electronically ignites the waste gas. Ignition is called for automatically at all times that Hydrogen is called for, and the unit attempts re-
Nitrogen Generator for Blending / Gas Dilution: Blending (aka gas dilution) involves the mixing of two or more gases to create a furnace atmosphere. Often the primary atmosphere (for example, hydrogen, dissociated ammonia, Exothermic or Endothermic gas) is mixed with nitrogen to create a fixed percentage of reactive gas (e.g. hydrogen).
/ Operating conditions: in an atmosphere of air, inert gases (nitrogen, argon, hydrogen), active atmospheres for carburizing, nitriding and other active diffusion atmospheres, in high temperature systems up to 1300°C, low vacuum in retort furnaces up to 10-2 mbar.
