How to do Pipe Insulation with Melamine Foam?

CHENGDU, China - Nov. 21, 2023 - PRLog -- The cold winter is getting closer and closer to us, with snowfall in the north and cooling in the south. Weather changes may not only make people sick, but also may cause harm to buildings, pipelines and other equipment due to freezing, water accumulation and other problems.

Temperature and weather changes accompanying seasonal changes can easily cause people's health problems, which are more obvious in some more extreme weather conditions. Similarly, buildings and other barriers that serve as our daily protection are also unable to withstand the harm caused by climate change.

Therefore, there are currently corresponding national standards for different building categories or heating equipment. Building good thermal insulation and other projects is a top priority for the environment and safety of daily life.

Pipelines are the lifeblood of city operations and are related to all operations of our lives. In Nangang District, Harbin, urban water pipes burst due to seasonal climate changes, causing water outages in seven streets and more than 80,000 households.

Because the pipeline will produce temperature stress when the temperature changes (thermal stress, the stress caused by the object not being able to freely expand and contract due to temperature rise and fall or the temperature of each part of the object being different), causing the pipeline to burst. In particular, different soil types in the soil layer have different moisture contents and frozen vein coefficients (which reflect the degree of deformation of frozen soil materials at low temperatures). Pipe explosions are relatively frequent during the spring and autumn freezing and freezing seasons.

Melamine foam (https://www.sinoyqx.com/products/melamine-foam/) is one of the commonly used insulation materials for pipe insulation. Melamine foam is a three-dimensional grid structure system with sufficient openings. The length-to-diameter ratio (L/D) of the grid is between 10 and 20, and the density is 8.5KG/M3. The opening rate of melamine foam is as high as over 99%. The fine three-dimensional grid structure effectively prevents the convective heat transfer of the air, and the unique low thermal stability makes it have good thermal insulation effect (thermal conductivity, 0.035 W/(m*K)), and become an irreplaceable lightweight thermal insulation material.

In the severe cold environment of winter, melamine pipe insulation plays a role in the normal operation of the heating system. Warmth is provided through pipes to homes, factories, shopping malls, etc. Some provide heating, and some provide warm flow. No matter which type, pipes are needed to transport them. During the transportation process, if the outdoor pipes are not protected in any way, they will quickly freeze when encountering outdoor cold air, which is not conducive to the transmission of warm current and heating. If these outdoor pipes are insulated with rubber and plastic, a stable temperature can be maintained inside and outside the pipes, and freezing will not occur.
