防腐方管是埋在地下的金属体，但是由于使用环境的原因，尽管小心翼翼地施工，一般方管难免容易老化，方管仍会有所损害缺陷，而要想延长方管的寿命，就要对方管进行外侧设防腐蚀层（Anticorrosion layer）。在实际的管道使用过程中，防腐方管多种型号可选，各种方管虽然类型不同但是各自都有其不同优点，在未来的发展中将会以防腐类型为主。因为防腐方管在施工和实际应用中拥有以下四大优势：

Anti-corrosion square pipe is a metal body buried underground, but due to the use of environmental reasons, despite careful construction, ordinary square pipe will inevitably be easy to aging, square pipe will still have some damage defects, and in order to prolong the service life of square pipe, it is necessary to install an anti-corrosion layer on the outside of the square pipe. In the actual pipeline use process, there are many types of anticorrosive square pipes. Although different types of square pipes have their own advantages, anticorrosive types will be the main type in the future development. Because the anticorrosive square pipe has the following four advantages in construction and practical application: 防腐方管在实际应用中的四大优势

Four Advantages of Anticorrosive Square Pipe in Practical Application

第一，施工简便，步骤快捷，在工厂和现场的工地上都可以进行施工。防腐方管的施工相对于旧时方管来说十分简单，无需重大设备和场地，现场操作十分适宜，可以在现场一边施工的过程中同时进行防腐。

First, the construction is simple and fast, and can be carried out in factories and on-site sites. Compared with the old square pipe, the construction of the anti-corrosion square pipe is very simple. It does not need major equipment and site. The site operation is very suitable. It can carry out anti-corrosion at the same time in the process of construction on the side of the site.

第二，寿命更长，普通方管有一定的寿命，当对普通材料进行防腐处理后，其寿命可长达20-30年或者是更长久，可谓是管道中的“寿星翁”，使用上就节省了更换维修及其它成本。

Secondly, the service life is longer, the ordinary square pipe has a certain service life. When the ordinary material is treated with anticorrosion, its service life can be as long as 20-30 years or longer. It can be called "Shouxing Weng" in the pipeline, which saves the replacement, maintenance and other costs in use.

第三，工程造价便宜经济。在方管的质量和寿命相结合的情况下对比，使用寿命和投资能达到合理的比例，比旧时管道更加经济适用，这也是人们采购的重要决定因素。

Third, the project cost is cheap and economical. In the case of the combination of quality and life of the pipeline, the service life and investment can reach a reasonable proportion, which is more economical and applicable than the old pipeline. This is also an important determinant of people's procurement.

第四，防腐方管以环保为中心做设计思路。在讲究绿色环保的今天，这种设计更符合时代进步的需要，在以后对于输送流体的载体管道，环保要求将会愈来愈严格，不能随时代环保发展的产品终将淘汰掉。

Fourthly, the design of anti-corrosion square pipe is centered on environmental protection. In today's environment-friendly environment, this design is more in line with the needs of the progress of the times. In the future, the environmental requirements for the carrier pipeline for conveying fluids will become more and more stringent, and products that can not be developed with the environmental protection of the times will eventually be eliminated.

近些年来因之市场发展需要以及工程需要，方管产品又陆续推出了各种类型的方管。而优质的防腐方管的防腐蚀系统，大部属于长效性，设计寿命均可达到三十年以上。老旧的方管在工程使用上即将淘汰，防腐方管在以后的市场发展将会占据愈来愈重的比例，未来管道工程建设它将是主力军。

In recent years, due to the needs of market development and engineering, square tube products have been introduced one after another. The anticorrosive system of high quality anticorrosive square pipe is mostly long-term, and its design life can reach more than 30 years. The old square pipe will be eliminated in engineering use, and the anticorrosive square pipe will occupy a more and more important proportion in the future market development. In the future, pipeline engineering construction will be the main force.
