Product Name: Three-Way Bellows Compensator for Coal Powder Pipe
Nominal Diameter: DN100-600
Nominal Pressure: 0.1-1.6 MPa
Connection Methods: 1. Flange Connection 2. Saddle Connection
The three-way bellows compensator for coal powder pipeline integrates the conduit with the adapter, with equal thickness, thus directly reaching the same strength design as the pipeline in terms of wear resistance. Additionally, inorganic fiber cotton is used as the genuine filling inside the bellows to prevent coal powder from entering, ensuring that the compensating function of the bellows is unaffected.
Compensation for any directional displacement of primary, secondary, and tertiary air flows, applicable to coal powder and hot gas two-phase fluid with flow rates of 15-30 m/s, operating temperature of 60°C, and wind pressure ≤ 500 mmH2O.
Pipe systems suitable for thermal displacement requirements of gas-solid two-phase fluids containing other solid dust and particles, with pressure ≤ 0.25 MPa.
Performance Features: High-temperature resistance, no powder leakage, minimal powder displacement stiffness; absorbs displacement in any direction, good flexibility to ensure free expansion of boilers and piping systems; easy installation and maintenance, simple hangers, long service life, and cost-effective investment. Widely used in 100∽600MW power generation units, fundamentally solves the problem of coal powder leakage, ensuring the normal and safe operation of the units.
Material: The corrugated pipe is made of 1Cr18Ni9Ti, while the connecting pipe is made of low-carbon alloy wear-resistant steel, offering excellent welding and abrasion resistance.
Selection and Installation Requirements:
The specialized three-dimensional corrugated compensator for coal powder pipelines can absorb axial displacement (X), lateral displacement in any direction (Y), axial compensation amount (Xo), and lateral compensation amount (Ymm), meeting the requirements of various units.
