Knowledge and use of anticorrosive spiral steel pipes
Anticorrosive spiral steel pipe plays a key and different role in People's Daily life. Anticorrosive spiral steel pipe usually refers to the use of a unique process to carry out processing of the general spiral steel pipe after anticorrosive processing, so that the spiral steel pipe has the corresponding anticorrosive function. Normally, it is used to resist moisture, rust, acid and alkali, and oxidation.
Use of anticorrosive spiral steel pipe
Spiral steel pipe is commonly used in fluid transportation and gas transportation, pipelines often need to be buried, downpipe or laying engineering construction.
The characteristics of easy corrosion of steel pipe and pipeline engineering construction and application, the decision of the construction of spiral steel pipe, engineering construction is not qualified, not only harm the service life of the pipeline, and even cause air pollution, fire accidents, explosions and other devastating accidents.
At this stage, basically all the spiral steel pipe application projects will carry out anticorrosive process processing on the pipeline, to ensure the service life of the spiral steel pipe and pipeline engineering safety performance, environmental protection and energy saving, the anticorrosive characteristics of the spiral steel pipe, will also harm the economic, practical and protection cost of the pipeline project
Process for corrosion protection of spiral steel pipe
The anticorrosive process of spiral steel pipe is different according to its usefulness and anticorrosive process. At the present stage, a very perfect anticorrosive mechanism has been generated. Spiral steel pipe is a semi-solid thermal spraying plastic
In general, epoxy resin or polyurethane with flame retardant is used to fill, and after coating, heat treatment process is carried out to obtain a new steel pipe with excellent oxidation resistance and wear resistance. In view of the convenience of engineering construction, simple engineering construction methods, easy to grasp and use, it is a kind of steel pipe used in consideration at this stage
For the selection of the form of spiral steel pipe anticorrosion, it is necessary to consider the main use, engineering construction conditions, cost budget and other factors. The construction site can carry out forging processing of steel pipe according to the required pressure vessel, but it is necessary to pay attention to the construction conditions, especially the dry processing of the engineering construction site.
Storage of anticorrosive spiral steel pipes
In the decoration industry, all kinds of anticorrosive spiral steel pipes are in different situations. Because of their different characteristics, there is a certain distance between pipes. The various characteristics of anticorrosive spiral steel pipes require everyone to master, but because of the contact of raw materials such as anticorrosive spiral steel pipes, the storage of anticorrosive spiral steel pipes needs special conditions
Corrosion corrosion spiral steel pipe storage period, the main requirements to choose the appropriate site, people need to consider many external factors and corrosion corrosion corrosion spiral steel pipe, therefore, if the site is clean, dry, natural ventilation, corrosion corrosion spiral steel pipe can not be displayed in the area of harmful substances, should immediately remove weeds and other dirt, stainless steel plate outer surface should be kept clean.
