Square pipe is a square pipe, widely used in industrial production and engineering construction.As we all know, the service life of goods and maintenance has a direct relationship, square tube is no exception.In order to prolong its service life, we must pay attention to the other pipe routine maintenance and maintenance.Here is a brief introduction about the side custody maintenance approach.
1.Cleaning and grinding: such as pipe side pipe damage should be polished, especially in contact with carbon steel scratches and splashes, cut slag damage caused by the need to carefully clean thoroughly polished clean.
2.Mechanical polishing: to use the appropriate polishing tools for polishing, requires uniform treatment, and to avoid over-throwing and re-scratching.
3.In addition to oil dust: welded pipe side pipe before pickling passivation, must be according to the welded pipe side pipe process to remove oil, scale, dust and other debris.
4.Water blasting: according to the different processing requirements, the choice of different micro glass beads, different process parameters, and avoid overspray.
5.Pickling passivation: the pickling passivation of the welded pipe must be carried out strictly according to the process requirements.
6.Cleaning and drying: after pickling passivation, should be strictly in accordance with the process of neutralization, washing, drying, and thoroughly remove residual acid.
7.Protection: welded pipe square tube surface treatment is completed, should do a good job of protection, to avoid staff stroking and oil, dust and other debris secondary pollution.
Through the other pipe routine maintenance, not only can greatly extend its service life, but also greatly improve its efficiency and safety in daily use, so we must remember the above method, remember the other pipe routine maintenance.
