RUBBER EXPANSION JOINT TYPE P-1

Product catalog summary
Specifications:
The document describes a universal PTFE expansion joint, Type P-1, suitable for DN 15 to DN 500. It features PTFE bellows with rotatable flanges, multiple convolution bellows, and stainless steel supporting rings. The bellows have self-sealing PTFE flange ends and are designed to repel foreign matter. The expansion joint is equipped with threaded holes and requires checking material resistance to temperature and medium.

Applications:
The expansion joint is used for conveying aggressive media, compensating axial, lateral, and angular movements, muffling vibration and noise, reducing thermal and mechanical tension, and compensating for installation inaccuracies. It is applicable in the chemical, pharmaceutical, and treatment and disposal industries.

Accessories:
Includes an internal guide sleeve of PTFE, a protective cover, and transport protection. Additional PTFE seals are necessary for installation in glass, graphite, or ceramic pipes.

Structure:
The PTFE bellows are available in PN 5.5, PN 9, and PN 10.5. The Type P-1 is equipped with check screws for transportation protection, which must be removed after installation. Compliance with technical instructions regarding reaction force, adjusting force, and fixed point load is required.

Performance Parameters:
The maximum permissible pressure varies with temperature and DN size, with specific values provided for temperatures up to +23°C, +100°C, +150°C, and +200°C. Vacuum operation parameters are also specified.

Materials and Corrosion Protection:
Materials include 1.0038 (S235JR), 1.4541, and 1.4571. Corrosion protection varies with DN size, including electro-galvanized and anti-corrosion primed options.

Movement Compensation:
Detailed movement compensation values are provided for axial, lateral, and angular movements across different DN sizes.

Dimensions:
Standard dimensions and connection details are provided, with additional options available upon request.
