Product Description
BS 4504 Type British Standard Rubber Expansion Joint PN10/PN16
Performance Features:
Flexible rubber joints, also known as shock absorbers, pipe shock absorbers, shock absorber throats, soft joints, etc., are pipe joints with high elasticity, high air tightness, medium resistance and weather resistance. Its performance Features include:
1. Small size, light weight, good elasticity, easy installation and maintenance.
2. It can produce lateral, axial, and angular displacement during installation, and is not limited by the user's non-concentric pipelines and non-parallel flanges.
3. It can reduce the noise transmitted by the structure during work and has strong shock absorption ability.
4. Our self-developed internal seamless high-pressure flexible rubber joint can more effectively prevent corrosive media from corroding the inner wall of the flexible rubber joint in high-temperature-resistant, acid-alkali-resistant, and oil-resistant pipelines, improving the use of life.
