Precautions for fire protection of insulation materials such as asbestos jointing sheet

Sun, 12 Apr 2020 22:32:48 +0800

When using asbestos rubber sheets, it is necessary to pay attention to whether the fire performance meets the standard while ensuring the thermal insulation effect. In addition, it must also help to save energy while preventing fire. Ignore the important principle of energy saving.

Inorganic thermal insulation materials are represented by rock wool and foam glass. The thermal conductivity of rock wool and slag wool under normal temperature conditions (about 25 ℃) is usually between 0.036 ～ 0.041W / (m · K). It is an inorganic silicate fiber and is not combustible. Rock wool has the characteristics of Class A fire protection and thermal insulation. It is specially designed and produced for the external thermal insulation thin plastering system of the external wall of the building. It is suitable for new or existing buildings with a dense structure such as concrete or brick walls. It can also be used as exterior wall insulation or energy-saving transformation, and can also be used as exterior wall insulation and fire protection isolation tape. It can be used in conjunction with insulation materials with a combustion performance of less than A grade to improve the fire protection and fire protection of the exterior walls of buildings.

The external wall insulation materials should be organically combined with the four university disciplines of building science, material science, fire protection science and environmental protection science. Any research that deviates from the four university subjects has relative one-sidedness and limitations. The following points need to be done for the fire protection of external wall insulation:

1) Strictly implement various fire protection regulations and fire protection systems;

2) Choose good insulation materials;

3) Take good fire protection measures at the initial stage of using insulation materials;

4) Do a good job of monitoring the construction process at the intermediate stage of the use of thermal insulation materials to prevent the possibility of various fires;

5) After the insulation material is made into an external wall insulation system, use the insulation system properly and prevent fire.

The problem of fire protection for external wall insulation should be integrated with various factors. It is not possible to prevent fires by relying solely on the fire resistance of insulation materials such as rock wool boards.

What are the characteristics of metal spiral wound gaskets?

When laying underground pipelines, due to its insufficient performance to adapt to the surrounding complex and changeable environment, many pipelines require wire gasket protection. Application range of metal spiral wound gaskets: sealing of flange joints of pipelines, valves, pressure vessels, condensers, heat exchangers, towers, manholes, hand holes in petroleum, chemical, metallurgy, electric power, shipbuilding, machinery and other industries. Application range of metal spiral wound gaskets: sealing of flange joints of pipelines, valves, pressure vessels, condensers, heat exchangers, towers, manholes, hand holes in petroleum, chemical, metallurgy, electric power, shipbuilding, machinery and other industries. The structural density of the metal spiral wound gasket can be made according to different locking force requirements, and the inner and outer steel rings are used to control its maximum compression. The surface accuracy of the flange sealing surface contacted by the spiral wound gasket is not high. The metal spiral wound gasket is especially suitable for occasions where the load is uneven, the joint force is easy to relax, the temperature and pressure change periodically, and there is impact or vibration. Spiral wound gaskets are the original static seals for flange connection processing of valves, pumps, heat exchangers, towers, manholes, and hand holes. Metal gaskets can play a very good role in protecting pipelines. It has made more sealing gaskets on the market. Metal spiral gasket manufacturers have a complete product series to provide users with different choices. Due to the different environment for laying pipes,

Manufacturers of metal wound gaskets have different shapes. The structural density of the metal spiral wound gasket can be made according to different locking force requirements, and the inner and outer steel rings are used to control its maximum compression. The surface accuracy of the flange sealing surface contacted by the spiral wound gasket is not high. The metal spiral wound gasket is especially suitable for occasions where the load is uneven, the joint force is easy to relax, the temperature and pressure change periodically, and there is impact or vibration.

Spiral wound gaskets are the original static seals for flange connection processing of valves, pumps, heat exchangers, towers, manholes, and hand holes. For example, the letter-shaped gasket has a good appearance and is very practical. It is completely in contact with the pipe when winding, and can be used flexibly under high temperature and high pressure, especially in vacuum conditions. After the metal gasket is wound, it can effectively prevent corrosion. In the metal gasket winding, pay attention to the uniformity and tightness, and do not clean up the mess randomly, especially the problems that should be paid attention to such as valves, holes, and corners.
