Description

MOBILE REQUALIFIER UNIT FOR GAS BUTTONS.

[001] This report describes the detailed description accompanied by illustrative figures of a new concept and physical structure of a gas cylinder requalifier unit, which describes an innovative unit for the requalification and maintenance of movable or fixed movable gas cylinders that enables it is transported to locations where its function is required, with easy accessibility, eliminating transportation and logistics costs and enabling real-time live requalification tracking offering efficiency, price, and quality of bottle requalification service of gas.

Problems to be solved Approximately 15 years ago, with the aim of improving control over gas cylinders and ensuring safe application to end consumers, the National Petroleum, Natural Gas and Biofuels Agency (ANP) in conjunction with the oil companies. have put in place a plan for timely maintenance and controlled scrapping of all gas cylinders on the market. Over the years, companies called Requalificadores have been created aiming at the maintenance of cylinders according to the norms and schedules established by ANP and ABNT (Brazilian Association of Technical Standards). In the case of gas cylinders the main applicable standard is NBR 8865.

[003] Over the years, the demand for the service has steadily increased, and the initial purpose of the requalifiers as guarantors of the safety of the cylinders has been partly lost, since none of them improved their processes, nor do they follow them in full, when not. are being inspected by external control entities, as would be required by the established standards, leaving much to be desired regarding the quality of service and its safety. In addition, over the past three years, the ANP's schedule has included the larger cylinders called B-190 or P-190, used for industrial purposes. These canisters, being large and heavy, have a much higher transport cost due to the need for winch trucks to handle, as well as the fact that only a few units can be transported at a time.

It has been thought and designed to solve these problems of lost time in transportation, bureaucracy, quality problems in requalification, and assurance of the execution of the services and of all necessary tests indicated in the standard with direct monitoring by the gas companies. the Mobile Gas Bottle Requalifier Unit, object of the present patent.

In this sense, the creation of a unit that offers a mobile requalification service, which would circulate throughout the country or be allocated, would be fully feasible, performing the requalification directly within or adjacent to the gas companies' bases. monitor and oversee the services being performed at any time they wish, avoiding current problems with existing requalifiers. State of the art There is no mobile requalifier for gas cylinders on the market. All are fixed, scattered in some states of Brazil.

For the most part, requalifiers feature used or improvised machinery due to the high cost of setting up an improved requalification plant, as well as there is no automated equipment available to handle the quantities of cylinders today. Basically they cope with the growing volume of cylinders, proportionally increasing the workforce, always keeping low-cost / low-cost employees solely for maximum profit in the process. This generates high turnover and especially many quality problems due to lack of training. This relentless pursuit of profit makes them all avoid using equipment that forms bottlenecks in production but is essential to meeting standards such as hydrostatic water testing.

[008] Such equipment is normally only used when ABNT inspections or when gas companies also perform control inspections, remaining off most of the time to avoid compromising production volume or not actually working.

For P13 residential cylinders, which require high monthly volumes, the single mobile unit would not be the best option due to the size and power required to handle the highest hourly volume produced, but can be implemented with dismemberment in more than one hour. container modules aiming at increasing the productive area (Fig 5), but maintaining the concept of mobile requalifier for high quantities of cylinders. This way you can meet the whole family of residential type P2, P5, P8 and P13 cylinders.

[010] For larger cylinders called industrial P20, P45, P90, P125, and P190 the concept of the single mobile unit becomes much more attractive, mainly due to the smaller physical size.

[011] In any version, quality control and general follow-up by both parties (requalifier / gas company) does not allow any condition to make up the service provided as it is currently done.

[024] Mobile Gas Bottle Requalification Unit, which is the subject of this patent, is a structure that can be moved by land, water, or sea, and contains all the necessary equipment to requalify gas cylinders following the standards. indicated by ABNT, such as NBR 8865, approved by the ANP and the gas companies. Where it is presented in three internal Layouts, one to be applied to a fixed or allocated container and another to be applied to a motor vehicle trunk, and the last one in the high production version with the use of several containers to assemble the process. The mobile requalifier unit has all the equipment necessary for the requalification, besides having the gas cylinder maintenance equipment involving the blasting and painting functions, kneading and / or exchange of handles and bases, as well as replacement of valves and others. cylinder components.

[025] Thus, the mobile requalifier can be mounted either inside containers or in a truck trunk. REQ IN BOX and REQ IN TRUCK respectively.

[026] In the first two options, one side shall be movable or removable to allow operators and cylinders free access to equipment. This is necessary due to the reduced space involved in the use of containers and truck chests, as they have dimensional limits defined by national and international rules.

[027] Depending on the size of the container, there is a possibility of using a small truck for support and support when opting for the single container version.

[028] Only a small number of people are required to operate the Mobile Gas Bottle Requalification Unit, at least three of which are better qualified for quality and process control posts, welding and final inspection and inspection operations. Thus reducing and optimizing the operation costs, besides offering quality in the services.

[029] For the Mobile Gas Bottle Requalifier Unit shown in the Internal Container Layout or for Motor Vehicle Trunk. After reaching its destination, it is unloaded or parked in a place indicated and appropriate to the current rules and regulations, including environmental of each state, so that it can be prepared for operation.

[030] In the Container configuration the Mobile Gas Bottle Requalifier Unit can be transported and allocated at various locations, including gas company bases or in a nearby area.

[031] Once positioned and / or mounted within the gas company base, or other locations, cylinders follow all standard processes required for requalification or maintenance. No possibility of process deviations, as the unit always allows monitoring by the customer at any time.

[032] The Mobile Gas Bottle Requalifier Unit, object of the present patent, in the Container or Trunk Layout Layout, is essentially composed of functional work stations for all the processes involved in the requalification and maintenance of the cylinders. These are: [033] Station A: where a visual receipt inspection is performed to verify that the cylinder is rusty, dented, or subjected to fire. If not, it will be scrapped. Upon inspection, it is secured to special hydraulic non-locking equipment to remove all valves and fittings. This removal is done through a hydraulic motor driven screwdriver and suitable sockets for each valve attached to the frame, which dramatically reduces valve damage as there is no impact on the process. It is then subjected to internal flushing with high pressure water to remove dirt and remaining gas residues through the nozzle inserted into the gas cylinder which is positioned upside down for the dirty water to drain. Then plugs are placed on the threads for later procedures;

[034] Station B; where after plugging in the open threads, the cylinder is blasted with grit to remove old paint and rust. This cabin is fully enclosed using standard turbine blasting machine;

Station C; where the handles and / or bases will be scrubbed, by means of hydraulic spouting devices, or replaced, as well as the bottom of the cylinder if necessary. For this purpose sanders or plasma will be used for cutting welds, sanders for deburring / finishing of removed welds, plasma for bottom cutting, and MIG welding for welds in general.
