Steel structure building has the characteristics of high strength and light weight, improved power and speed, and has been widely used in the construction industry, and the ductility and seismic resistance of steel structure are outstanding, the construction time is short, and it has been increasingly used in building construction.

However, the high temperature resistance of the steel structure is not very good. In the case of a fire, the temperature of the steel structure will rise to more than 540 degrees in just a quarter of an hour. The steel structure is easily deformed at high temperatures, which may cause accidents. The construction of the fireproof coating happens.

The principle of fire protection and heat insulation of ultra-thin or thin steel structure fire-retardant coatings is that the fire-retardant coating layer expands and foams when exposed to fire to form a foam. The foam layer not only insulates oxygen, but also has an outstanding thermal insulation function because of its loose texture. It can delay the heat transfer to the substrate to be protected. According to the analysis of physical and chemical principles, the process of the foam layer due to the expansion and foaming of the coating undergoes an endothermic reaction due to the expansion of the volume, which also consumes the heat during combustion, which is beneficial to decrease The temperature of the system and the effects of these aspects make the fire-resistant coating produce obvious fire and heat insulation effects.

The fireproof and heat insulation principle of thick steel structure fireproof coating applied on steel components is that when the fireproof coating is exposed to fire, the volume of the coating basically does not change, but the thermal conductivity of the coating is very low, which delays the transfer of heat to the insured substrate The fireproof coating itself is non-combustible, and it has the effect of shielding and avoiding heat radiation to the steel components, avoiding direct flame and high temperature attack on the steel components.

Why does the hose harden after being used for a long time?
The PVC hose will harden after a long time. Although PVC resin is as hard as conventional PVC hoses, in the process of wrapping rubber hoses or cables, adding a softener (oil) called "plasticizer" to the hose can become soft. The addition here does not refer to a chemical reaction, but refers to the mixing of PVC molecules with each other, just like holding hands.
However, due to external stimuli (ultraviolet rays or temperature, etc.), the plasticizer separates from the fluid and oozes out of the surface of the hose. This phenomenon is generally called "sticky", but as the phenomenon continues, the plasticizer in the hose will continue to decrease, and over time it will become as hard as a PVC hose.

The metal hose is the main pressure-bearing part in the pressure pipeline, which has a compensating effect and at the same time acts as a sheath for the bellows. It is commonly used in pipes that require sufficient flexibility to prevent vibration in piping. Its operating temperature range is extremely wide, ranging from -196 to 600 degrees.
The pressure range of the hose is generally PN0.6-32.0Mpa, up to 42.0MPa. According to the pressure in the pipeline and the application site, one or more layers of stainless steel wire or steel belt can be selected for weaving; according to the corrosiveness of the medium through the pipeline, the appropriate stainless steel grade can be selected to ensure the corrosion resistance of the hose.
As far as high-pressure tubing manufacturers know, compared to other hoses, corrugated metal hoses have a longer lifespan, have good flexibility, fatigue resistance, high pressure resistance, high and low temperature resistance, corrosion resistance, etc., and the overall economic benefits are very high.
With the development of modern industry, there are higher requirements for the performance of metal hoses, such as more high temperature resistance, high pressure resistance, etc., and there is more demand.

Light weight rubber hose products are one of the commonly used accessories in the daily industry, but various problems can also occur during use, especially when high-pressure hoses are working under high pressure. After years of work experience and user feedback, we can understand the reasons:

1. The reinforcing layer of the hose is not rusty, but there are irregular broken wires. If the hose is broken, peel off the outer rubber layer and check that the reinforcement layer is not rusted, but there are irregular broken wires in the length direction of the reinforcement layer. The main reason is that the hose is subjected to high-frequency impact.

2. Due to external force (shrapnel breakdown, squeezing and breaking) or system overload, the high-pressure hose has a large break or is about to break, you can take the bone connection method: wipe the break of the hose and remove the broken part; self-made The steel "bonding" is inserted into the cut hose (when the situation is particularly urgent, a steel pipe with the same outer diameter as the hose bone diameter can be used as "bonding" use a self-made steel plate clip to connect the hose to the "bonding" card Tight (when the situation is particularly urgent, you can use No. 8 iron wire to replace the self-made steel plate clip); clean the connected hose and use it

3. The hose is broken and the braided steel wire near the breach is rusty. If the high-pressure tubing breaks, peel off the outer rubber layer and check that there is rust on the braided and wound steel wire near the breach. This is mainly due to the moisture or corrosive substances in the outer rubber layer, which weaken the strength of the rubber pipe and cause it to break under high pressure.

Note: The hose arrangement should try to prevent the heat source and keep it away from the engine exhaust pipe. If necessary, equipment such as casing or maintenance screen can be used to prevent the hose from deforming due to heat. The hose equipment should be prevented from being in tension. Even if there is no relative movement between the two ends of the hose, the hose should be slack. The tensioned hose will swell and reduce its strength under the effect of pressure.

Understand the production process of pvc hose and use the products better! I believe that everyone will understand the basic knowledge of pvc materials in daily life, and they must have seen such a material product. Of course, its light texture now has been liked by many consumers. But I don’t know how much you know about pvc pipe production technology? What should you pay attention to in the production process?

When it comes to the production technology of pvc pipe fittings, in fact, the first thing we have to control is the temperature. For pvc materials, its basic processing performance is relatively narrow, and its thermal stability is relatively poor, so there are certain requirements for the temperature range during processing. Under normal circumstances, the processing temperature is the best, between one hundred and sixty to two hundred degrees Celsius, and if necessary, it should be determined according to the specifications of different extrusion equipment and molds, so as to meet the basic processing requirements.

When processing pvc pipes, the feedstock and the speed of the host machine must be coordinated. The two are the key indicators that affect the plasticizing effect. We must strictly control the torque and melting pressure range during the processing, and there must be sufficient At the same time, there must be stable shear friction heat, so as to ensure the endurance of the screw and form a good plasticization process, so as to form a complete pipe.

The above are the basic things that need to be paid attention to during the processing. In addition, it is also necessary to pay attention to the speed of equipment operation during the processing of pvc pipes, which will also affect the molding and quality of the product, so strict checks must be made during the production It is good at all levels, so that we can form a more complete pvc pipe and provide more quality products for our market.

How to install the corrugated expansion joint correctly? Let's take a look at these points:

1. Before installing the compensator, check its model, specification and pipeline configuration, and it must meet the design requirements.

2. For compensators with inner sleeves, care should be taken to ensure that the direction of the inner sleeve is consistent with the flow direction of the medium. The hinge rotation plane of the hinge type compensator should be consistent with the displacement rotation plane.

3. The compensator needs to be "cold-tightened", and the auxiliary components used for pre-deformation should be removed after the pipeline is installed.

4. It is strictly forbidden to use the method of deformation of the corrugated compensator to adjust the installation tolerance of the pipeline, so as not to affect the normal function of the compensator, reduce the service life and increase the load of the piping system, equipment, and supporting components.

5. During the installation process, welding slag is not allowed to splash on the surface of the wave shell, and the wave shell is not allowed to be damaged by other machinery.

6. After the piping system is installed, the yellow auxiliary positioning components and fasteners used for installation and transportation on the corrugated compensator should be removed as soon as possible, and the limit device should be adjusted to the specified position according to the design requirements, so that the piping system has Sufficient compensation capability.

7. All movable components of the compensator shall not be stuck by external components or limit their range of movement, and the normal movement of each movable part shall be ensured.

8. During the hydraulic test, the secondary fixed pipe frame at the end of the pipeline with compensator should be reinforced to prevent the pipeline from moving or rotating.

The metal hose is similar to a long metal cleaning hose suitable for family use. Because of its steel structure, you should be able to push any household water pressure through the metal garden hose without worrying that it will burst. Compared with many telescopic hoses on the market, this is undoubtedly an improvement.

Metal hoses are used in various fields. Such hoses have relatively strict requirements on quality. For example, they are essential fittings in industries closely related to life such as petrochemical industry, steam and gas.

In terms of size, the metal hose has a diameter, and the length of the hose also affects it. In terms of pressure, we use p to express it.

In addition, the medium is mainly determined according to the corrosion resistance table, and the material of each part is also determined by this.

The material of each part directly plays a decisive role in the quality of the hose, because the connection parts of the plastic-covered metal hose are often determined by some relatively small parts. Its chemical properties directly affect the quality of the connection.

The last is the state. The so-called state refers to the state of the metal pipe when it is in use. The length of various motion states of the metal pipe should be referenced, and the radius of minimum bending should be calculated. With the help of these data, we can choose the length of the metal hose and then install it correctly, which also directly affects its quality.
