FAQ
Q: For abrasive slurry or mining tailings applications, which material grade is recommended?
A: Heavy-wall carbon steel with hardened wear-ring inserts is recommended for tailings conveyance.
Q: How does a buyer arrange third-party pre-shipment inspection by SGS, Bureau Veritas, or TÜV?
A: Buyers coordinate directly with their chosen inspection agency and share the booking reference with our export team, who then schedules the inspection at the factory 3-5 days before container loading, with inspection fees typically borne by the buyer.
Q: What's the practical difference between 304 and 316 stainless steel couplings for corrosive fluid transfer?
A: 316 stainless offers significantly better resistance to chloride-based corrosion (seawater, certain fertilizers) due to its molybdenum content, while 304 is sufficient for general water and mild chemical transfer at a lower unit cost.
Q: What specific components are checked during the recommended 500-hour maintenance inspection?
A: The 500-hour inspection covers gasket seal integrity, lever pin wear, ball-and-socket contact surface pitting, and lock-ring spring tension.
Q: Does the 30° omnidirectional articulation rating apply equally across all sizes from DN50 to DN300?
A: The full 30° articulation applies up to DN200; larger DN250-DN300 sizes are rated to 20° due to increased ball-joint contact area affecting sealing integrity at higher deflection angles.
