1. PTFE‑lined bellows expansion joint: resistant to high temperatures, corrosion, and high pressure. This product features a specially engineered PTFE hose and a high‑temperature‑resistant braided stainless‑steel double‑clamp spiral hose, making it suitable for demanding environments involving high temperatures, corrosive media, and elevated pressures.
2. Bellows expansion joints utilize the effective axial and lateral deformation of their corrugated bellows to accommodate dimensional changes in pipelines, ducts, vessels, and other components caused by thermal expansion and contraction, or to compensate for axial, lateral, and angular displacements. They can also be used for noise reduction and vibration damping.
3. Metal hoses compensate for axial and angular displacements in pipelines and provide pressure resistance, seismic protection, and noise reduction.
4. Rotary compensator, a displacement‑compensation device for district heating pipelines, primarily consists of inner and outer tubes, sealing packing, and a spring‑preloading mechanism. Its distinguishing feature is that the spring‑preloading flange and the inner tube are machined with high precision to achieve an extremely tight fit, minimizing clearance. This utility model is typically used in pairs or triples to absorb axial displacement and axial thrust in district heating pipelines.
5. Spherical compensators compensate for pipe deflection caused by foundation settlement and thermal expansion–contraction. They offer advantages such as large compensation capacity, compact footprint, low fluid resistance, easy installation, and low overall cost.
6. Sleeve compensators, installed in straight pipelines. Suitable for hot water, steam, and oil‑based media; they compensate for thermal expansion by allowing the inner sleeve to slide relative to the outer sleeve.
