Petroleum pipeline fixing band with horizontal length adjustable

Abstract

The invention discloses a petroleum pipeline fixing band with the horizontal length adjustable. The petroleum pipeline fixing band comprises a steel strip piece. A rectangular connector is installed at one end of the steel strip piece, a steel column protruded outwards is arranged at the position of the center of the rectangular connector, the surface of the steel strip piece is provided multistage locating holes, the positions of two ends of the steel strip piece are respectively provided with a horizontal fixing frame simultaneously, two ends of each horizontal fixing frame are connected with a horizontal steel plate respectively through locating bolts, the ends of the horizontal steel plates are connected with outer protection bands, and rectangular connectors are installed at one end of each outer protection band. The petroleum pipeline fixing band has the advantages that the petroleum pipeline fixing band saves time and labor and can be stabilized on petroleum pipelines of different pipe diameters, the flush degree of later cutting is guaranteed, and connection of a cut pipe section and a new pipe section is facilitated; by arranging three layers of fixing bands and a plurality of horizontal fixing plates which can be dismantled and installed at any time, errors in the horizontal direction can be reduced, and cutting accuracy is not influenced.

Description

technical field [0001] The invention relates to an auxiliary tool for oil pipeline maintenance, in particular to an oil pipeline fixing belt with adjustable transverse length. Background technique [0002] At present, pipe fittings used in petroleum, chemical industry, electric power, shipbuilding, metallurgy, machinery, textile, food, construction, pharmaceutical and other industries need to have high strength, pressure resistance, corrosion resistance and high temperature resistance. In the oil industry, it is necessary to lay long pipelines for oil transportation, but because most of the oil pipelines are laid in relatively harsh environments, leakage and rupture often occur. Repair welding is performed on the pipe. If the damage is large and repair welding is impossible, the damaged part needs to be cut off and replaced with a new pipe section. During the replacement process, the cutting nozzle should be kept flush. Now the general process is to manually surround the ou...

Problems solved by technology

Now the general process is to manually surround the outer wall of the oil pipeline with a circle, and another person draws a line along the circle with a special stone pencil, and then cuts along the drawn line. When the pipe diameter is large, two Only one person can complete the line drawing work at the same time, which is a waste of manpower, and due to the lack of effective tools, the drawn lines are often not guaranteed to be even, which affects the final connection and sealing effect with the new pipe section

It should be pointed out that a single tool cannot ensure the accuracy of line drawing in harsh environments, and the degree of fixing in the horizontal direction for different pipe diameters needs to be improved
