Air cooling island vacuum pipeline double hinge expansion joint2024-04-08 14:44:32: The double hinge expansion joint of the air cooling island vacuum pipeline has a directional ring with two pairs of mutually perpendicular hinge structures in the circumferential direction. The designed universal ring, hinge, and pin can withstand the thrust formed by internal pressure on the expansion joint, so it can absorb angular displacement in any plane. Usually, when absorbing displacement, two or three combinations should be used....

Rotating compensator2024-04-08 14:43:01: Rotating compensator is a new type of compensator with large compensation capacity, no pressure thrust, and corrosion resistance. The compensation function is to form a rotating force couple through the rotating cylinder and its connecting pipeline (force arm), and compensate around the virtual rotation center by relying on the thermal expansion thrust of the pipelines at both ends of the compensator....

Three way coal powder expansion joint2024-04-08 14:37:45: Applicable scope:Suitable for compensating displacement in any direction of primary and tertiary air pipelines with coal powder+hot air gas-solid=phase fluid, flow rate of 15-30m/S, working temperature of 60-450 ℃, and wind pressure ≤ 500mmH2O.Suitable for pipeline systems with pressure ≤ 0.25Mpa and other solid dust and particles, where the thermal displacement of gas-solid two-phase fluids needs to be indicated....

Corrugated expansion joints for power station industry2024-04-08 14:25:55: The corrugated expansion joint is used in the power plant industry for the smoke and air duct of the power plant. It adopts a rectangular cross-section, and a single expansion joint in the pipeline can withstand two-dimensional displacement. The elbow joint pipeline composed of two expansion joints can withstand three-dimensional displacement.The rectangular corrugated expansion joint used in the power industry, also known as rectangular compensator or rectangular corrugated pipe, has axial, horizontal, and angular compensation functions. It is used for the inlet and outlet of air conditioning pumps, fire pumps, and domestic water supply pumps, effectively reducing host vibration, absorbing pipeline noise, protecting equipment, and extending equipment service life. It has the advantages of withstanding high temperature and corrosion....

Sleeve type pipeline expansion joint2024-04-08 13:55:42: The characteristics of sleeve type pipeline expansion joint compensator. The strength is very high, and the friction coefficient is low, which can reach 0.04-0.10. Secondly, it does not age and has a long service life. In addition, its maintenance is also very convenient, as compensation for thermal expansion can be achieved through the sliding motion of the outer sleeve through the sliding sleeve....

Rectangular non-metallic expansion joint2024-04-08 13:52:49: The rectangular non-metallic expansion joint is composed of flexible compensation components, flanges or connecting pipes, insulation materials, and bolt tie rods, which can provide large axial, angular, and lateral displacement within a small size range. The characteristic is no reverse thrust, and the main material is fiberglass fabric and its coated products, which cannot transmit effectively. The use of non-metallic compensators can simplify design, avoid the use of large brackets, and save a lot of materials and labor. Subsequently, it plays a role in noise reduction and shock absorption (fiber fabrics and insulation cotton themselves have sound absorption and shock absorption effects, which can effectively reduce the noise and vibration of systems such as boilers and fans). At the same time, it has excellent high temperature resistance, corrosion resistance, and sealing performance. It is coated with polymer materials such as organic silicon and fluorine, which have excellent high temperature resistance, corrosion resistance, and sealing performance. Easy installation and maintenance....

Non metallic expansion joint (fabric fiber expansion joint)2024-04-08 13:50:06: The selection of materials for non-metallic expansion joints needs to be based on various parameters and environmental factors, and the materials for each part of the expansion joint should be selected separately. The various components that make up non-metallic expansion joints are different and play different roles. When selecting materials, targeted selection is necessary....

Metal rectangular expansion joint2024-04-08 13:46:32: The metal rectangular expansion joint is an important component of the safe operation of large cross-sectional area flue gas quality transportation pipelines in power plants, metallurgy, cement, and petrochemical equipment systems. Compared with similar single angle, double angle, and low wave tangent small ballpoint pen angle products, it shows excellent work in geometric and material nonlinear deformation caused by temperature and load. Our excellent quality quality is increasingly recognized by various design institutes, engineering units, and project owners, and has been widely promoted and applied....
