To prolong the service life of cold-drawn steel pipes, the first thing to think about is to do a good job of its anti-corrosion work. Because most of the pipes are stored outdoors, it is the easiest to rust after wind, rain and sun, and thus suffer from corrosion. Anti-corrosion products can be added to the pipe when it is manufactured. Anti-corrosion in the user's pipe can also improve the smoothness of the pipe. Since the above mentioned production of cold-drawn steel pipe, then we will talk about its processing, requiring large diameter pipe processing is to improve the pressure-resistant thick-walled pipe. Thickness as half of the wall, such as steel welded into double-layer pipes, the strength will be higher than non-single-layer pipes, to prevent damage. In order to improve the strength, toughness and weldability, steel-making technology should be strengthened and controlled rolling should be widely used.
In addition to the above points can extend the service life of cold-drawn steel pipe, in addition to the daily use of attention to its maintenance work, after all, the production process is certain, will be limited, can not be long-term maintenance, so it needs a certain maintenance work to extend the service life.
