Φ 300-400 precision cold drawn round tube
Our factory mainly promotes ultra large specification precision cold drawn round pipes with an outer diameter range of 300mm-400mm and a wall thickness coverage of 5mm-45mm. The thick wall specifications are rich and the pressure bearing performance is strong, specifically suitable for high-end industrial scenarios such as large fluid conveying systems, high-pressure hydraulic cylinders, and heavy machinery equipment. The product is made using precision cold drawing integrated molding technology, with a dense and uniform tube body, precise dimensional tolerances, and a bright and smooth surface. It effectively solves common problems such as rough inner walls, large precision deviations, high pressure leakage, insufficient strength, and short service life of traditional large-diameter steel pipes. The overall pressure resistance, sealing, and structural stability are excellent, and it supports deep customized processing. It is a high-quality…
