Flexible Coupling, V. Johnson Coupling
The V. Johnson flexible coupling from Jilin Senfeng Pipe Co., Ltd. is manufactured from ductile iron with a fusion bonded epoxy (FBE) coating, designed for use in water and wastewater systems. It complies with ISO2531, BS EN545, BS EN598, AWWA C219, and ASME B16.42 standards, enabling it to accommodate angular deflection up to 5 degrees and axial movement of up to 25 mm. The coupling is rated for operating temperatures between -40°C and 125°C and is suitable for potable water, sewage, and industrial effluent pipelines. It is available in nominal diameters from DN50 to DN2000, with universal models covering DN50 to DN600 for multiple pipe materials.
The base material is nodular cast iron, meeting the mechanical properties of Grade 50-7-04 per ISO 1083, with a minimum tensile strength of 500 MPa and elongation of at least 7%. The FBE coating is applied in accordance with ISO 21809-2, providing a minimum thickness of 300 microns and resistance to cathodic disbondment. This coating ensures long-term corrosion protection in aggressive soil and submerged conditions. The coupling is designed to work with plain-ended pipes made of ductile iron, carbon steel, HDPE, PVC, FRP, or GRP, without requiring special fittings or welding.
This coupling is commonly sourced by municipal utilities, infrastructure contractors, and water treatment plant operators across Europe, North America, and Southeast Asia. Buyers typically require certification documentation for ISO and AWWA compliance, along with pressure test reports. Packaging is on wooden pallets wrapped in plastic film to prevent surface damage during transit. Trade terms are typically FOB Dalian or CIF destination port, with minimum order quantities negotiated per project volume. Lead times are generally 30 to 45 days after deposit confirmation.

Sourcing Flexible Coupling, V. Johnson Coupling from Jilin Senfeng Pipe Co., Ltd. - China Import Guide
Before ordering, verify the material certificate for ductile iron grade (ISO 1083), FBE coating thickness (minimum 300 microns), and pressure test records per ISO 2531. Request sample couplings with full documentation, including gasket material compliance and coating adhesion test reports. Confirm that the supplier’s production matches the stated standards - some vendors may substitute lower-grade iron or thinner coatings without disclosure.
Confirm Incoterms with the supplier: FOB Dalian is typical, but CIF or CFR may be offered for larger volumes. Lead time is generally 30 to 45 days for standard sizes and 45 to 60 days for custom ODs. Payment terms are usually 30% advance with balance against BL copy. Ensure packaging is palletized with plastic film and labeled per international shipping standards to prevent damage during transit.
Perform visual inspection upon arrival for coating damage, gasket integrity, and surface corrosion. Verify that the coupling ID tags match the order and batch numbers. Conduct a random sample of couplings for pressure testing at 1.5x operating pressure. Request a copy of the supplier’s last third-party audit report, even if not certified, to assess quality control practices. Retain all documentation for warranty and compliance purposes.
