Heat protection method of anticorrosive steel pipe
Anti-corrosion steel pipe is a new type of pipe, through anti-corrosion treatment, can effectively prevent or reduce the corrosion of chemical or electrochemical reactions during transportation and use
However, it belongs to a good anti-corrosion steel pipe, must pay attention to when using; Stay warm, especially during the cold winter months
Heat prevention measures for anticorrosive steel pipes
In fact, there are many cooling methods for anti-corrosion steel pipes, including coating insulation materials, attaching anti-corrosion materials around anti-corrosion steel pipes, and supplementing and insulation for anti-corrosion steel pipes. In detail, these are:
The anti-corrosion steel pipe is coated with thermal insulation coating to prevent heat, that is, the application of expanded perlite, expanded frogstone, asbestos powder, asbestos fiber, diatomite clinker and other amorphous thermal insulation materials, followed by cement, water glass, refractory binder or coagulant
Then proportional distribution of water and stir evenly, the formation of mud, or exposed some of the insulation material on the hand or painted on the anti-corrosion steel pipe and tools, this kind of anti-corrosion steel pipe cooling method is also known as coating insulation.
The anti-corrosion steel pipe is packaged with insulating materials to insulate the resistance, that is, insulation materials such as slag felt, glass wool felt, rope, asbestos rope or cotton tape can be directly packaged, so as not to worry about the anti-corrosion steel pipe being frozen and cracked. Does not affect the application of anti-corrosion steel pipe
The anti-corrosion steel pipe is supplemented with insulation material, that is, when the insulation material is a block material, it can also be supplemented with insulation; However, in the construction process, the support ring made of round steel is fixed on the pipe wall, its thickness is the same as the insulation layer, and then the support ring is packed with iron, aluminum or chicken wire, and then the insulation material is used to insulate the resistance
Material supplement; Complementary measures are also able to utilize rigid curved blocks made of prefabricated porous porous materials as support structures, spaced approximately 900mm apart
According to the technical parameters of the pipe insulation layer, the flat braided barbed wire is cut, the winding mechanism is made into a circle, so that the slag wool is attached to the support ring, and then the metal protective cover is used to supplement the insulation structure.
In addition, we can also use prefabricated insulation treatment of anticorrosive steel pipe to maintain insulation. The main materials of prefabricated insulation products are foam concrete, asbestos, diatomite, slag wool, glass wool, rock wool, expanded perlite, expanded verite, calcium silicate and so on
Prefabricated pipe insulation structure, the general aperture DN≤80mm, the application of semi-circular shell, such as DN≥100mm, the application of fan tile (curved tile) or trapezoidal tile.
Ok, the above is about the anticorrosive steel pipe cooling method, in general, anticorrosive steel pipe has four main cooling methods, but different cooling methods have different insulation measures
Therefore, many people are carrying out the insulation treatment of anti-corrosion steel pipes, at this time, it is necessary to choose a suitable cooling method, which can help the anti-corrosion pipes successfully winter
