大口径钢管的镀锌也叫做大口径镀锌钢管，是指在大口径钢管表面有热浸镀或电镀锌层的焊接钢管。镀锌可增加钢管的抗腐蚀能力，延长使用寿命。镀锌管的用途很广，除作输水、煤气、油等一般低压力流体的管线管外，还用作石油工业特别是海洋油田的油井管、输油管，化工焦化设备的油加热器、冷凝冷却器、煤馏洗油交换器用管，以及栈桥管桩、矿山坑道的支撑架用管等。
Galvanized large-caliber steel pipe is also called large-caliber galvanized steel pipe. It refers to welded steel pipe with hot-dip or galvanized coating on the surface of large-caliber steel pipe. Galvanizing can increase the corrosion resistance of steel pipe and prolong its service life. Galvanized pipes are widely used not only as pipelines for general low-pressure fluids such as water, gas and oil, but also for oil wells and pipelines in petroleum industry, especially in offshore oilfields, oil heaters, condensers and coolers for chemical coking equipment, pipes for coal distillate wash oil exchangers, and supports for Trestle pipe piles and mine tunnels.
