Axial noise reduction hand-wound double sphere flexible rubber joint carbon steel
Product Description:
The height and thickness of the manually wound rubber joint ball are adjustable, and the ripple of the ball can be selected from one, two, or more. In non pressure situations, it is recommended to choose some special sized manual winding joints to save mold costs. With the special properties of rubber such as long-distance elasticity, non breathability, medium resistance, climate resistance, and radiation resistance, it can reduce the vibration and noise of pipelines, and compensate for thermal expansion and contraction caused by temperature changes.

Applications:
Liwei provided the drawings required for the expansion double ball joint, simplifying the customer's installation process. The working temperature range is -15 ℃ to 80 ℃ (with special variants that can handle -30 ℃ to 150 ℃), allowing the product to be used in environments with different thermal conditions. This makes the double ball flexible rubber joint an excellent choice for heating and cooling systems, industrial processing plants, water and wastewater treatment facilities, and many other temperature fluctuation factors.
Advantages:
- Appearance: The external surface is smooth and free of defects such as burrs, rust, pores, slag inclusions, cracks, mechanical damage, etc.
- Welding: The weld seam should be flat, without pores, cracks, slag inclusions, and welding omissions. The roundness of the flange should comply with relevant standards.
- Anti corrosion: The flange is pickled and rust removed, and then subjected to anti-corrosion treatment.
- Product packaging: Measures such as rainproof, moisture-proof, rust proof, and shockproof should be taken. Our company generally uses plastic cloth, woven fabric and straw rope packaging, without recycling; Or packaged according to the demand side's requirements.
