Function and Features of Wholesale Curved Tube Pressure Balance Corrugated Compensator

Wholesale Curved Tube Pressure Balance Corrugated Compensator has the functions of pressure resistance, sealing, impact resistance, vibration reduction and noise reduction, which can reduce the deformation of the pipeline and improve the service life of the pipeline. Also known as expansion joint, expansion joint is a flexible, thin-walled, transversely corrugated device with telescopic function, which is composed of metal bellows and components. The vertical welding assembly clearance and pre-weld preparation are basically the same as all-position welding.

Wholesale Curved Tube Pressure Balance Corrugated Compensator

Wholesale Curved Tube Pressure Balance Corrugated Compensator can compensate for the temperature difference deformation or other deformation between the equipment and the pipeline because of its flexibility, and can prevent shock, vibration, reduce the thrust of the pipeline on the equipment and adapt to the uneven settlement of the oil tank foundation. The non-metallic compensator itself is sealed, so it can be widely used in chemical, oil refining, electric power, light industry, atomic energy, metallurgy, machinery, instrumentation, ships, aerospace and other departments. Since power pipes and heat pipes are widely used in various sectors of industry and civil use, the demand for non-metallic compensators is very large. In recent years, many large and medium-sized cities are building a large number of residential buildings. From the perspective of saving energy and eliminating environmental pollution, central heating and urban heating should be vigorously promoted, so they are inseparable from heat pipes. In the thermal transformation of the original city, a troublesome problem encountered is that it is difficult for the thermal pipeline to pass through, especially the square compensator is difficult to arrange due to its large footprint. At this time, the non-metallic compensator has a compact structure. , to give full play to its particularity.

The vertical welding seams of the Wholesale Curved Tube Pressure Balance Corrugated Compensator tube are all in the horizontal welding position. Before arc breaking, reflow 5mm to blow out the slag. 120A, the angle between the electrode and the workpiece is kept at 20°, the molten pool in non-metallic compensator welding is controlled as an oblique ellipse shape, the size of the molten pool should be uniform, and it should be basically the same every time the arc is extinguished and stopped, and the electrode replacement speed should be fast. At the end of the end, press down the arc. When it is 4mm away from the end, push the electrode slightly forward, continue to weld over 3-5mm, and then control the electrode to extinguish the arc on the underside of the groove.

The cover surface can be used in the order from the bottom, the welding rod does not swing, and the straight line method is used for multi-layer welding. The arc of the pass weld should be welded along 1/3 of the down groove, the 1/3 of the pressure pass should be welded, and the arc should be on the upper side of the pass weld, and the third pass and so on. The thickness of each layer of Wholesale Curved Tube Pressure Balance Corrugated Compensator should not exceed 4mm to prevent slag inclusion. It should be noted that the upper part should not be undercut. After each welding, no coating should be applied, and it should be cleaned after all welding.
