Product Description:
Constructed of high quality elastomeric materials and customized with bolts and nuts, the Double Ball Flexible Rubber Fittings are designed to withstand a variety of media including air, water, sewage, acid and oil. The design incorporates two balls for enhanced flexibility, allowing greater movement and absorbing vibration, noise and shock within the system. This feature is particularly beneficial in preventing damage and leakage, thus ensuring uninterrupted operation and reducing the need for frequent maintenance.
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.
