Patent number: 10941885Abstract: The invention relates to a process for producing a multilayer pipe (1) from a tubular element having a metallurgical bond comprising at least one outer pipe (10) of metallic material and one inner pipe (20) of metallic material arranged within the outer pipe, the inner surface of the outer pipe (10) being mechanically bonded to the outer surface of the inner pipe (20) at least in parts of their interface, in which, in a production line, the tubular element is simultaneously heated and drawn, wherein each portion of the tubular element is submitted to heating by induction and then to hot-drawing, wherein the tubular element is drawn with a mandrel located therein. Through this process, the existing mechanical connection between the pipes is trans-formed in a metallurgical connection. The invention also relates to a multilayer pipe (1) produced for this process, wherein the outer pipe (10) is made of a carbon manganese steel alloy and the inner pipe (2) is made of a corrosion-resistant alloy.Type: GrantFiled: July 23, 2014Date of Patent: March 9, 2021Assignee: VALLOUREC SOLUÇÕES TUBULARES DO BRASIL S.A.Inventors: Julio Marcio Silveira E Silva, Timo Ebeling, Hezick Da Silva Perdigao, Danielle Granha Giorgini, Antonio Wagner Da Silva Penna

Patent number: 10710163Abstract: The present invention relates to an automatic system for measuring and machining pipe ends having measuring equipment that has an internal laser sensor and an external laser sensor. The system can also have a machining station that has at least one machining tool for machining the inner diameter of the pipe and at least one machining tool for machining the outer diameter of the pipe, which are centralized and operated independently of each other. In some embodiments, the system has an electronic interface central between the measuring equipment and the machining tools, having records of critical values of outer diameter and inner diameter for the pipe end, the electronic interface central receiving measured values of outer and inner diameters from the measuring equipment, comparing them with the critical values, and controlling the operation of the machining tools as a function of the result of the comparison.Type: GrantFiled: September 16, 2016Date of Patent: July 14, 2020Assignee: VALLOUREC TUBOS DO BRASIL, S.A.Inventors: Julio Marcio Silveira E Silva, Marcelo Jardim De Souza, Felipe Leal Carvalho, Gustavo Alves Pinheiro, Andre Ricardo De Souza E Sa

Patent number: 10300516Abstract: A process for producing a multilayer pipe by expansion is disclosed, with or without heating, in which a multilayer pipe (1) comprises at least one outer pipe of metallic material (10) and an inner pipe of metallic material (20), the inner pipe of metallic material (20) having a yield strength lower than the yield strength of the outer pipe (23) and an external diameter smaller than the internal diameter of the outer pipe. The process for producing the multilayer pipe comprises a mounting step (34) between the pipes (10, 20), wherein the inner pipe is inserted inside the outer pipe, and at least one mechanical expansion step (36), comprising moving a mandrel (2) longitudinally and internally in the inner pipe (20) while the outer pipe and the inner pipe are held at a fixed position, wherein at least part of the mandrel (2) has a greater external diameter than the internal diameter of the inner pipe.Type: GrantFiled: July 23, 2014Date of Patent: May 28, 2019Assignee: VALLOUREC SOLUÇÕES TUBULARES DO BRASIL S.A.Inventors: Julio Marcio Silveira E Silva, Timo Ebeling, Hezick Da Silva Perdigao, Danielle Granha Giorgini, Gustavo Alves Pinheiro, Jochen Peter Ames, Antonio Wagner Da Silva Penna

Publication number: 20180094625Abstract: This invention refers to a suction filter (B) for hermetic compressor of type “variable speed” comprised, preferably of an arrangement of a volume (5), two tubes (1, 2), an inlet nozzle (3) and an outlet nozzle (4), having an internal resonant system, in which is positioned a set (10) of ducts (9), these having variable length. Different lengths represent different tunings for each frequency band of interest, and the fixed diametrical dimension having an perimeter extension at the base of the suction filter (B), the perimeter extension having an extension greater than or equal to the resonant tube (9), but smaller than or equal to the length of the tube. In the suction filter of the present invention the resonators (9) and the position of them are determined by the need for attenuation of the filter without introducing losses to the pulsating flow in the filter.Type: ApplicationFiled: September 29, 2017Publication date: April 5, 2018Applicant: Huangshi Dongbei Electrical Appliance Co., LTD.Inventor: Marcio SILVEIRA
