FAQ

The sound of water pipes will not produce infrasound damage to the human body?

Most of the polyethylene benzene board insulation, paste the external walls.

For example, HDPE pipe with a flexible connection is a flexible interface, PVC-U of the glue plug-in method, is just helium pouring a lie on the pizza pull the interface, wire then, flange it more

PM25 and other dust particles mosquito 4 The The The One of the most critical is that the window is not New Zealand, to know that China's outdoor air quality is very bad And closed doors and windows (especially air conditioning or warm and warm equipment must be closed when the window), the indoor air in a variety of superimposed pollution (decoration pollution, carbon dioxide exceeded)

Rigid pipes differ from flexible piping, those are rigid pipes that are flexible piping

Can be made of polystyrene particles by the pre-die into the steam completely foam self-adhesive after the formation of foam block through the line to form a polystyrene board

How is the flexible tube of FRP composite pipe defined

I am not an expert and have occasionally slept on the foam board. Personal feeling sleep in the above airtight, but also hot, easy to get angry.

Is the clamp type flexible connector connected to the pipe to the rubber pad?

See the situation, the general 3 percent or so, to see how the management of LZ, hand thank you

According to the intrinsic composition of insulation materials can be divided into: inorganic insulation materials and organic insulation materials! Fire rating A is a non-burning point with the insulation effect of materials, materials. Class A non-combustible materials have the characteristics of low density, low thermal conductivity, high pressure capacity, convenient construction, economical and durable. They are widely used in thermal insulation materials and industrial industries such as hot pipes, thermal equipment and other industrial piping equipment and industrial buildings And the civil building envelope structure of the insulation, insulation, sound absorption materials. Because of its good thermal stability, and more for the steel structure of the fire protection coating material. Fire rating B1 level is a flame retardant insulation material, is determined according to the fire resistance of the material, in addition, different parts of the material division is also different! Burning performance: refers to the material and / or products in case of fire burning all the physical and / or chemical changes, that is, the fire reaction characteristics. Fire rating B2 is a combustible insulation material also known as flame retardant materials, mostly organic insulation materials, add the right amount of flame retardants. More common for EPS expansion polystyrene board and XPS extruded polystyrene board, that is, we often say that general board. This material is low in ignition and releases a lot of harmful gases during the combustion process. Fire rating B3 is a flammable insulation material, this is more common as the main material of polystyrene foam insulation material, because this material is easy to burn,

Plastic tube most afraid of what the East unitary

In general, polyurethane sandwich panels can be used in a variety of building needs, including industrial plants, public buildings, combined housing, purification projects and other construction areas

What is the difference between a flexible pipe and a rigid pipe? What types of pipes are used for drainage pipes, heat pipes and gas pipelines?

Stainless steel corrugated hose is not easy to aging, the two ends of the connection is more difficult to fall off, the safety performance is more reliable
