Wheatland Tube has more than 100 years of experience making steel tube and pipe, and is a division of the largest independent tube manufacturer in North America — Zekelman Industries. At Wheatland, we use the latest technology to produce superior-quality galvanized pipe and tubing available in a broad range of sizes, gauges and lengths.
Mechanical Tube In-Line:
Our in-line galvanizing process offers superior flexibility and quality when compared to products made from pregalvanized coil or post-hot-dipped galvanized tube. In-line galvanizing produces a bright, virtually lead-free coating that is exceptionally durable and can stand up to the most severe fabrication processes — all without flaking or chipping.
Schedule 40 Hot Dip:
Wheatland’s hot-dipped galvanizing process is straight forward. The pipe is submerged in a pickle tub to remove all the scale and rust, both inside and out. The pipe is rinsed and then dunked in a pre-flux to ensure good adhesion of the zinc. The bare pipe is then submerged into a kettle of molten zinc. It then passes through an outside diameter air wiper for a uniform finish. The inside diameter is then blown clean with a blast of hot steam. The pipe cools on a cooling rack on the way to the white rust inhibitor bath.
