inquiry Inquiry (采购产品): inquiry Thermal metallising systems Item – 1 Plasma spray machine Plasma spraying system suitable to coating all the industrial parts from scuff resistant coatings on pump shafts, bushes, valve seats, piston rings, to thermal barriers on turbines and resistant abrasion coatings in bearing housing, and repair the equipments which use in oil refinery. The wearing away or destruction of metals and other materials by the abrasive action of water, steam, slurries which carry abrasive materials. Pump parts are subject to this type of wear. System is designed to meet the needs of the general purposes, as well as being suitable for aerospace application, by providing arobust, easy to use and inexpensive to run system. The system providing a mass flow controls to precisely meter the flow of gases to the pistol. These gas controls are completely segregated from the electrical system and are freely vented to prevent any possibility of gas build up, which may be a concern when using hydrogen as a second gas, in addition the metallization system can be operated using nitrogen as secondary gas. The system must be included elements shown below. - Pistol - Control unit - Refrigerated heat exchanger - Metal powder and powder feeder - Power supply three phase – 380 v – 50 Hz - Inventer power supply units - Any device that is system required. Metal powders description The metal powders which are should be supplying with system under these description below: 1 Low – alloy steels that contain chromium as the principal alloying element. 2 Alloy content of 2-6% including carbon. These alloys are often used as build up materials under higher-alloy coatings. 3 Chromium (Cr) as the chief alloying element with total alloy content of 12-25%. Many of these alloys also contain molybdenum. 4. Tungsten, Nickel and Cobalt blends. They are excellent choices at service temperatures below 900oF and when extreme toughness is required. They are considered as very good high abrasion – resistant and exhibit the best protection for metal-to-metal wear. Quantity of groups above should be for two years service. The whole system is integrated to provide reliable and reproducible results with simple to understand operation and a long life. Interconnections between the various components have been designed such that is almost impossible to make a wrong connection. The control connection between the control panel and the gas controls are contained in a single umbilical cable. Hoses are color coded for ease of recognition and safety. Also almost any material can be sprayed including metals. - Spare parts for two years operation. QTY -------------------------------------------------------ONE Notes which should all the companies to consider for req. 31/2008 metallising machine 1 - Note for item 1 (Plasma system PS 50M – PC) Item 1 (Plasma system PS 50M-PC) A) SRC need to know about the primary & secondary gases which will be mentioned in the offer which they are hydrogen & nitrogen & helium & arcon, is those gas will be supplied with the machine by it’s special bottles with all the connections required to connect it in the system or that will depend on the person who work on this machine? B) For the powder which will use, should be supplied with the machine considering that the materials is carbon steel & cast steel & stainless steel & SRC want to know how to order in the future certain QTY by Kg considering that the machine will use weekly to repair two pcs. Each week. C) SRC want the offer mention to the training on the machine for item 1 & 2 especially for the item 1 since the modern type and need good training for good period. Item – 2 Light weight Arc spray system System specification - Hand sprays head. - Quick connecting front-end assembly. - Light weight spray head. - Simple and reliable nozzle design. - Emergency stop. - Suitable to repair small components. - All system components are assembled on one rugged caddy. - Pneumatic tires – easily moves over shop floor obstacles. - Utilizes inventer power supply technology. - Three phase – 380v–50 Hz. The available electricity. - Easily removed to accomplish gun maintenance. - The metal to be use in spray should be supplying with system for two years operation included multi type to using for carbon steel, stainless steel, alloy steel, etc. QTY --------------------------------------------------------- ONE TRAINING COURSE - Complete training course for plasma and arc machines in origin contary. - The course Duration ------------ one month - The number of participants ------------ five persons - Training outlines included the Fundamentals for the plasma and arc metallising process for getting enough experience. DOCUMENTS AND ORIGIN. 1- Operating manuals for each machine in English language. 2- Electrical and control diagram. 3- Europe origin. Item 2: Wires type which using in are spray system must be supply according to the description below: No. Wire Material Wire size Qty. 1 Metallization wire 06E Nickel 1.6 m 2 Roll 2 Metallization wire phosphor Bronze 15E 1.6 m 2 Roll 3 Metallization wire steel 30E, 35E, 45E, 55E, 60E, 65E, 80E, 84E 1.6 m One Roll for each type 4 Metallization wire 70#, 71E, Model 1.6 m 3 Roll for each type **** Hidden Message ***** Amelia Punzalan 204 Al reem tower, Al Maktoum Road, Deira DubaiARE Company: Trade Masters Title: Secretary Phone: 0097142284490 / 0097142289960 Fax: 0097142282873 / 0097142217658 E-mail: main@trademasters.ae **** Hidden Message ***** main@trademasters.ae |
