Definitions

  • the present invention relates to a thick film coating method applicable to gaseous oxygen pipeline equipment.
  • Equipment and accessories for gaseous oxygen pipelines such as valves, valves, check valves, filters, tubes, flanges or the like, are currently and traditionally made of materials of alloyed steel type, low alloyed or unalloyed.
  • the high-grade nickel and / or copper alloys of the Monel or cupro-nickel type are much more rarely used because of their very high cost and certain implementation difficulties that are peculiar to them.
  • the parts constituting the envelope under pressure that is to say mainly the body, the cap, the flanges or the like, of each equipment of a gaseous oxygen line are generally composed of one or more homogeneous mono materials. -métalliques.
  • US-A-6,089,828 teaches the realization on a gas turbine element of a wear resistant coating formed of an aluminum alloy and bronze.
  • JP-A-57070306 and US-A-2,300,400 disclose coatings formed from nickel / chromium alloys.
  • EP-A-825272 relates to the thermal projection of a coating of copper, lead and bronze.
  • J P-A-2001323361 proposes coatings based on nickel / aluminum alloy.
  • the problem that arises is then to propose an equipment or an element of such equipment intended to be arranged on a pipe carrying oxygen under pressure not having the aforementioned risks and disadvantages of the equipment of the prior art.
  • the solution of the invention is then a method of manufacturing a piece of equipment or a piece of equipment made of steel or a steel alloy, capable of being put in contact with oxygen under pressure during its use, in which a thermal projection coating of a projection material is carried out on at least a portion of the surface of said element or equipment so as to obtain at least one coating layer on said surface of a thickness less than or equal to at 5 mm, characterized in that the projection material is selected from nickel and nickel and copper alloys.
  • At least one protective layer formed of nickel or a nickel / copper alloy, is deposited on the surface of the equipment or the piece of steel equipment or a steel alloy, which surface is capable of being contacted with oxygen under pressure during use, so as to protect this surface with one or more protective layers and thus avoid the aforementioned problems.
  • the method of the invention may comprise one or more of the following characteristics: a coating with a thickness of 0.1 mm to 5 mm is produced.
  • said element or equipment is made of steel, cast iron or stainless steel.
  • said element or equipment comprises an internal cavity or passage, and in that said coating is operated on at least a part of the internal wall of said cavity or of said internal passage.
  • the projection material is nickel or alloy consisting mainly of nickel and copper, and may further include some additional alloying elements such as chromium or cobalt.
  • the projection material is pure nickel or a nickel / copper (Ni / Cu) alloy comprising up to 60% by weight of copper, the balance being nickel.
  • the coating is made by plasma thermal projection, that is to say, by a method of "blown plasma” type, APS (for Air Plasma Spray in English) or HVOF (for High Velocity Oxy Fuel).
  • the coating is made by blown plasma using a gas chosen from argon, hydrogen, helium and nitrogen as a carrier gas.
  • an additional protective layer of a second completely oxidized material preferably of the ceramic type. Indeed, it takes three elements to generate a combustion, namely an oxidizer, a fuel and energy. Therefore, it may be necessary in critical places to add a second layer of oxide that will create a thermal barrier and reduce friction or abrasion heating (energy), which will improve safety.
  • said element or equipment, new or existing is chosen from valve bodies, parts of revolution, or any other gaseous oxygen channeling equipment.
  • the invention also relates to a piece of equipment or an item of equipment, for example a simple piece of piping, such as a flange, a straight section, a stitching, an elbow, a tee or a reduction, intended to be put into place.
  • contact with oxygen under pressure during use comprising a body made of steel or steel alloy, characterized in that it comprises at least one coating layer made of a material chosen from nickel and alloys of nickel and copper, on at least a portion of the surface of said body, said coating layer having a thickness less than or equal to 5 mm.
  • the invention also relates to a method for conveying oxygen under pressure using at least one oxygen line in which oxygen is conveyed under pressure, characterized in that an equipment or element of equipment, for example a pipe element, according to the invention or obtained by the manufacturing method according to the invention is arranged on said pipe and is contacted with oxygen under pressure flowing in said pipe.
  • an equipment or element of equipment for example a pipe element, according to the invention or obtained by the manufacturing method according to the invention is arranged on said pipe and is contacted with oxygen under pressure flowing in said pipe.
  • the invention consists in improving the safety of equipment made of steel or steel alloy intended to be used in contact with oxygen by coating in one or more layers, typically from 1 to 5 mm, by projection. thermal a nickel or nickel / copper type exemption material and / or oxides, on the inner or outer walls subjected to the oxygen pressure of any equipment or piece of equipment, in particular piping, intended for the oxygen service.
  • the mechanical interfaces of the equipment are coated, whether new or used equipment or equipment that needs to be improved.
  • the material or equipment thus treated can be used in oxygen service under the following conditions:
  • the oxygen content of the equipment in use may be less than or equal to 100%
  • the service pressure of the equipment in service can be at most 50.10 6 Pa (500 bara), but typically less than 25.10 6 Pa (250 bara), and
  • the equipment operating temperature is between -40 ° C and + 200 ° C.
  • the material or equipment thus treated presents the same conditions of safety and reliability as the same material made of massive exemption material.
  • FIGURE represents a gate valve 1 with a gate-type integral passage 10 with a control rod 10 (here in the closed position), which is usually used on the oxygen pipe 2 of which the security has been improved by the present invention.
  • a nickel coating has been operated on the inner surface 4, 5, 6 of the valve 1, that is to say on the surface 4, 5, 6 coming directly into contact with the oxygen 3 during use of the valve 1 and on the mechanical connection interfaces to be coated 7, 8, 9.
  • This nickel coating was operated on the aforementioned "blown plasma” type thermal spray deposition method. It should be noted that this coating also makes it possible to repair possible pores of the base material.
  • valve coating As mentioned above, the present invention is not limited to valve coating but applies to any element or equipment used to convey oxygen under high pressure.
