Description

Fluorine-lined elbow joint

Technical Field

The invention relates to the technical field of fluorine-lined elbow pipes, in particular to a fluorine-lined elbow pipe joint.

Background

The bending pipe is bent by adopting a complete set of bending equipment and is divided into two processes of cold bending and hot pushing. No matter which kind of machine equipment and pipeline, the elbow pipe is mostly used for oil transportation, gas transportation, liquid transportation, engineering bridge construction and the like. Pipe bending machines can be broadly classified into numerical control pipe bending machines, hydraulic pipe bending machines, and the like. The application of the pipe bender is as follows: the hydraulic pipe bender is mainly used for electric power construction, highway construction, pipeline laying and repairing in the aspects of boilers, bridges, ships, decoration and the like, and has the advantages of multiple functions, reasonable structure, simplicity in operation, convenience in moving, rapidness in installation and the like. The machine has the pipe bending function, can also use the oil cylinder as a hydraulic jack, has the characteristics of low price and convenient use compared with numerical control pipe bending equipment, and occupies the leading product position in the domestic pipe bending machine market. The numerical control pipe bender can perform winding type bending of one bending radius (single mode) or two bending radii (double modes) on a pipe in a cold state, and is widely used for bending various pipe fittings and wires in industries such as automobiles, air conditioners and the like. The pipe bender is mainly used for plastic forming of pipes. The elbow is made of cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, nonferrous metal, plastics and the like. In the application process of the traditional oil-based lubricating products, the production efficiency of an enterprise is greatly restricted, because the flowability and the difficult cleaning property of the oil-based lubricating products further cause pollution to the production environment and the working conditions of workers, and the enterprise usually needs to spend a large amount of money and manpower and material resources for removing the pollution. The adoption can reduce for the enterprise and avoid paying out of above-mentioned manpower and materials that clear up the pollution even, but its wash-free directly welded characteristic, the production efficiency and the product quality of improvement enterprise more greatly. And the dosage of the IRMCO water-based elbow grease can be reduced by 50-80% compared with the traditional lubricating oil under the normal condition, so that more cost can be saved for enterprises.

At present, the fluorine-lined elbow joint still has a certain part to be improved in practical use, the joint is sealed only by a sealing gasket, a secondary sealing device is not provided, connection dislocation is easily caused when certain bending occurs, screw holes in a flange plate are all round through holes, and bolts are inconvenient to screw.
