Definitions

  • This invention relates to pressure cylinders used for the transportation and storage of liquefied petroleum gas or other hydrocarbons.
  • liquefied petroleum gas (LPG) to be used at residences and offices, is offered for sale in cylinders, the bodies of which are manufactured by welding together two or more metal parts.
  • Hot worked steel sheets thickness of which varies in the range of 1.5-2 mm, are deep drawn in hydraulic presses to manufacture the upper and lower bodies of the cylinder. Then the body halves, on which edge-cutting processes and bending are applied, are passed through the cleaning pool together with auxiliary body parts such as the footring and the handle in order to make them ready for the welding processes. Before the welding processes, the bushing is welded onto the top of the body so as to place the valve opening. Body welding is performed in submerged and mig/mag welding machines whereas the attachment of the footring and the handle to the cylinder body is performed in mig/mag welding machines.
  • the permanent internal stresses which build up as a consequence of the welding processes are released by applying stress relief and/or normalisation heat treatment on the cylinders.
  • Completed cylinders are subjected to first visual inspection then to welding, body damage inspections, and hydrostatic tests. After the tests, the surfaces of the cylinders are cleaned in the grit/shot blasting unit. Ready surfaces of the cylinders are coated with zinc and/or an undercoat painting against oxidation. In the next step, the surfaces of the cylinders are painted.
  • Manufactured cylinders are transported several times between various places including the manufacturing plant, the filling station, the sales unit and the final consumption site.
  • the metal handles and the feet of the cylinders that are stacked at storage sites, transportation vehicles and places of use, experience permanent deformation due to the over-weight and their repair or renewal processes are costly.
  • the deformed handles and feet cause the paintings of the cylinders to be worn easily, and even the porter to be wounded while carrying the cylinders.
  • plastic handles have been developed in the prior art, devised to be used on the upper parts of the bodies of cylinders that contain 6 kg. of LPG.
  • the plastic handle which is used with cylinders with a plastic ingredient cannot be used with high-capacity cylinders since its strength is insufficient even though it is a cheaper component as compared to a metal handle.
  • German Utility Model No DE20010514U1 discloses a gas pressure container made of metal to contain the pressurized media, such as gas cylinder for combustion gases with the capacity "V", consisting essentially of a cylindrical shell, two outwardly curved final grounds and equipment for setting up and carrying the container, in which at least a central final ground comprises one connecting piece.
  • the object of the present invention is to realise a cylinder which absorbs the impacts directed to its top or bottom parts much better when compared to those in the prior art.
  • a further object of the present invention is to attain a cylinder which is rustproof, does not require maintenance or painting, and which does not get dirty quickly.
  • a still further object of the present invention is to realise a cylinder onto which signs and/or trademarks can be applied easily.
  • a further object of the present invention is to realise an ergonomic cylinder which is easy to handle.
  • Another object of the present invention is to realise a cylinder with an aesthetic appearance which enhances customer satisfaction.
  • the cylinder which is subject to the present invention, in its most basic form, comprises a steel body in which liquefied petroleum (LPG) gas is carried and stored, a regulator for the gas to exit, a valve, a handle on the top, which enables it to be carried easily by the user, a lid placed on the handle and which covers the recesses and provides an aesthetic appearance, a base at the bottom which enables it to stand in balance, and is characterised by two internal pieces, one for the handle and one for the base, which absorbs external impacts and protect the cylinder from external factors.
  • LPG liquefied petroleum
  • the cylinder of the present invention comprises a body (2) which is manufactured from steel by a known technique, and which has a suitable geometry, preferably the form of a cylinder with rounded (torispherical, elliptical, hemispherical) upper and lower ends. There exists a bushing recess (14) on the top of the body which enables placement of accessories such as the valve, regulator, etc.
  • studs (12) are welded on the top and bottom of the cylinder, which are sufficient in numbers, preferably four on each side, to provide the necessary strength.
  • At least one internal piece (3) is attached to each group of studs (12) at the top and at the bottom.
  • protrusions (9) are placed on said internal pieces (3), which have the sufficient number to provide strength, and which are preferably step-formed. Said protrusions (9), by seating into corresponding channels (10) of the handle (4) at the top and the base (5) at the bottom, absorb impacts and mechanical stresses on all mounting pieces, behave like a spring so as to enable distribution of the load and thereby avoid breaks and material damages occurring during stacking and loading-unloading of the cylinders.
  • the internal piece (3) has preferably a circular form the diameter of which decreases from the centre to the top.
  • the external diameter is a few millimetres larger than the diameter of the body (2) of the cylinder (1).
  • the internal piece (3) comprises recesses (11) on its body, into which the studs (12) on the body (2) of the cylinder (1) seat.
  • the internal piece (3) comprises cut-outs (8) (on its top and bottom surfaces so as to provide optimum material usage, to allow passing-through of rain water and other liquids, and to provide space for placement of equipments like the valve and the regulator.
  • the cylinder (1) which is subject to the present invention, comprises a handle (4) on top of the internal piece (3), which has a form fitting to that of the internal piece (3).
  • the handle (4) enables the cylinder (1) to be carried easily, protects the accessories mounted on the body (2) of the cylinder (1) such as the valve and the regulator, and allows markings to be made in accordance with the standards and legislation which is compulsory in cylinder (1) manufacturing.
  • the handle (4) comprises a groove (15) on its upper surface.
  • the surface area of the groove (15) is equal to the circular area of the lid (6) which involves a recess extending over an arc of a certain angle, and its depth is equal to the wall thickness of the lid (6).
  • the number of recesses (11) is preferably four.
  • the handle (4) further comprises ergonomic columns (13) which enable the cylinder (1) to be carried easily and into which the studs (12) seat.
  • the bottom surface of the handle (4) is flat so as to enable marking.
  • a lid (16) is employed to hide the four recesses on the handle (4), to carry information relating to the properties of LPG, the filling station, security warnings, etc.
  • the lid (16) may be of a colour different than the rest of the design and thereby allows for geographical, regional or technical differentiation of the products.
  • the geometry of the lid (16) matches the geometry of the handle (4), has a circular form, and comprises at the bottom a number of teeth (10), preferably four, for its attachment to the handle (4). All these parts are integral, i.e. mono-block, and manufactured in a single plastic injection mould and/or in separate injection moulds.
  • the cylinder (1) of the present invention comprises a base (5) which enables standing upright on the floor and being stacked on top of each other.
  • the diameter of said base (5) decreases from the centre to the bottom.
  • the base (5) comprises a number of channels (10) which match with the protrusions (9) of the internal piece so as to provide the necessary strength.
  • the base (5) further comprises recesses (11) into which the studs (12) on the body (2) of the cylinder (1) are inserted during the assembly. For the assembly of the base (5), the studs (12) are first inserted into the recesses (11) and then they are fixed with nuts.
  • the base (5) further comprises cut-outs (8) on its body, to provide optimum material usage and also to allow draining of rain water or other liquids.
  • the surface of the base (5) has a flat form that enables marking to be made in accordance with the standards and legislation which is compulsory in cylinder (1) manufacturing.
  • the internal piece (3), the handle (4), the base (5) and the lid (16) are made of a rustproof material which does not require repair or painting, does not get dirty quickly, and has high impact and mechanical strength.
  • the material is preferably ethylene propylene diene terpolymer added copolymer polypropylene, however other polypropylene derivatives and suitable additives may also be used.
  • Said polymers may be selected from a group comprising polymers such as PBT, ABS, PE, POM, PC, or mixtures of these in certain ratios.
  • the polymer pieces of the cylinder (1) which is subject to the present invention, protect critical areas which are prone to collisions and impacts.
  • the body (2) part of the cylinders (1) which are placed side by side at various places such as storage and consumption sites, are not allowed to contact each other.
