What are the insulation materials used for copper pipes for building hot water? Pros and cons?

Why perlite? Then you go one by one.

1. The construction process of cast-in-situ cement expanded perlite: grassroots cleaning, measuring elevation, making ash cake, cement expanded perlite mixing, cement expanded perlite shooting, exhaust duct cutting, ventilation pipe buried.

Precautions: 1. Cement expanded perlite is mixed with a mixer according to the design mix ratio or atlas requirements to ensure the mixing quality.

2. Cement expanded perlite is laid with shovels or other tools.

3. The exhaust duct is cured for one day of expanded perlite, and then the exhaust duct is cut according to the requirements of the specification.

4. The steam pipe is now one of the highlights of excellence, and there are many practices. Usually 50pP diameter PVC pipe and stainless steel are used.

2. As for the insulation of copper pipes, it is necessary to test the pressure: the requirements for the pressure test of the pipeline shall be determined by the design unit or the construction unit according to the nature, pressure, temperature and other parameters of the input medium. If there are no specific provisions, the pressure test can be carried out according to the times of the generated pressure, the time is 10 minutes, and no leakage is qualified.

As for the process, the first generation does not have the characteristics of good anti-freezing, heat preservation, energy saving, hygiene, safety, durability, etc., and the thermal conductivity is too strong. It is recommended to use the second generation product.

Today's hot water copper pipes, the more commonly used fiber rock wool or Owens insulation, generally occupy more volume.

If you want to install heating pipes in your home, you should choose limb insulation materials. Take a look around the market, and you will find that there are still many types of insulation materials. What are the insulation materials? How should consumers choose insulation materials?

1. What are the insulation materials for heating pipes?

1. The more popular is the rock wool pipe, which is generally suitable for equipment pipelines and plays the role of heat preservation. It has a wide range of applications in the market, and this rock wool has a certain moisture-proof performance, and can also be used in rainy seasons.

2. You can also choose a glass wool insulation material, its volume and density are relatively small, but the thermal conductivity is relatively low, and it is corrosion-resistant, has very stable properties in the chemical environment, and the thermal insulation properties are also very good.

3. There is also a kind of insulation material called polyurethane, generally speaking, it is more suitable as an insulation material for heating pipes, it can be buried in the inner wall or ground, and the construction is more convenient.

Second, how to choose the insulation material of the pipeline.

1. Generally speaking, because the weather in northern cities is relatively cold and the climatic conditions are quite different, we must choose high-efficiency insulation materials to insulate the pipeline, and the ultimate goal is to reduce the loss of heat and will not be affected by the external environment.

2. The more prominent is to choose rock wool or asbestos, including glass wool, etc., the thermal insulation products made of these materials are very good, the thermal conductivity of thermal insulation can not be exceeded in general, the moisture content should be controlled at about the same time, and the compressive strength is relatively high, so it should be achieved.

3. What are the characteristics of pipeline insulation materials?

A high hunger wheel is characterized by its relatively low thermal conductivity, but it can improve its thermal insulation effect, coupled with the insulation layer, it can achieve a better waterproof purpose, has met the national standards, and has a relatively long service life.

Summary: If you want to buy insulation materials for heating pipes, there are many Qixin materials to choose from, such as polyurethane or rock wool pipes, including glass wool, etc., these materials are very good.

1. Rock wool pipe is a kind of rock wool insulation material mainly used in pipelines. Rock wool tube shell is widely used in petroleum, chemical, metallurgy, shipbuilding, textile and other industrial boilers and equipment pipeline insulation, but also used in the construction industry partition wall, ceiling and interior and exterior wall insulation and various types of cold and hot pipes and hidden, exposed pipe insulation.

2. Polyethylene insulation material is produced by special technology, and its bubble cell is a closed-cell structure, which has the characteristics of heat insulation, moisturizing, anti-condensation, anti-aging, etc., and is widely used in heat insulation, moisturizing, and cold retention of air conditioning and types of cold and hot pipes.

Polyethylene insulation material is a high-performance energy-saving material, under the same conditions, the material is less than other materials, and the construction is convenient and fast, in order to shorten the project cycle, improve the construction quality, improve the reliable guarantee.

3. Silicate composite thermal insulation material is a new type of thermal insulation material, which is composed of high-quality natural mineral magnesium silicate, added with chemical additives and high-temperature adhesives, and manufactured by pulping, molding, shaping, drying, finished products, packaging and other processes.

4. Aluminum silicate insulation material, also known as aluminum silicate composite insulation coating, is a new type of environmentally friendly wall insulation material. It meets the national construction standards and is a necessary material for many real estate developers, engineering contractors and decoration contractors.

5. High-temperature glass wool insulation material is a lightweight, durable, high-temperature insulation material with superior thermal insulation performance composed of uniformly slender, elastic glass fiber and special high-temperature adhesive.

There are three commonly used pipeline insulation materials: rock wool pipe, glass wool and polyurethane. The properties of these three materials are as follows:

1. Rock wool pipe. Rock wool pipes are mostly used in petrochemical, metallurgy, shipbuilding and textile industries for boiler or equipment pipeline insulation, sometimes widely used in the construction industry in the partition wall, indoor ceiling and wall insulation and other thermal insulation. However, the insulation of pipelines in the power industry, petrochemical industry, light industry and other industries is used in the thermal insulation and thermal insulation measures of various pipelines, especially for pipelines with small pipe mouths, which can be implemented quickly, and the waterproof rock wool pipe has special properties such as moisture-proof, hydrophobic and temperature discharge, and is suitable for use in a rainy environment, and it has water-repellent properties.

2. Glass wool. Glass wool, it has good formability, low bulk density, low thermal conductivity and other characteristics, glass wool corrosion resistance is also extremely high, in the chemical corrosion environment has good chemical properties. The adaptation characteristics of glass wool are for the insulation of air conditioners, exhaust pipes, boilers and steam pipes.

3. Polyurethane. Polyurethane, which is mostly used in the production of cold storage, refrigerated trucks or fresh-keeping boxes, can also be used as a thermal insulation layer for color steel sandwich panels, and polyurethane is sometimes used in petrochemical tanks. Polyurethane also has the effect of thermal insulation and cold insulation, and is applied to petrochemical and metallurgy, especially in the outer layer protection of various types of buried composite directly buried pipelines.
