Here's a fast, informative look at TOBO GROUP's pipe fittings manufacturing and product range. In this video, we walk through our Shanghai sales office and five branch factories, showing how forged socket welding and threaded fittings are produced—from raw materials to machining, heat treatment, and quality testing. You'll see elbows, tees, reducers, caps, crosses, bends, stub ends, couplings, and more, plus the inspection processes behind them. A clear, practical overview for B2B buyers sourcing pipeline products from China.
