High temperature resistant metal hoses can generally withstand high temperatures

201 stainless steel is a metal hose that is not too corrosion-resistant, his corrosion resistance is relatively poor, but he is the lowest metal hose material, all still have a certain applicable group, the overall performance of 201 is low, the highest temperature that the metal hose made by him can withstand is 260, which is more suitable for some neutral environment media.

301 stainless steel is a member of the stainless steel 300 system, his high temperature resistance and corrosion resistance than the 200 series of stainless steel has a certain improvement, in the weak acid and weak alkali environment, the comparison is also relatively good, and his strength is better than the 304 and 316 series of steel, the highest temperature he can withstand is 300 degrees, widely used.

304 stainless steel is the most widely used stainless steel in the stainless steel family, he can not only withstand the temperature of comparison, but also perform very well in strong acid and alkali environments, his maximum temperature is 450

The last one is the top layer of the stainless steel family, 316 series stainless steel, this kind of metal hose has good corrosion resistance, high temperature resistance, the maximum temperature of 316 can reach 600, 316L can even reach 700

Metal hoses can withstand temperatures up to 600 degrees Celsius. The pressure resistance depends on the wall thickness and the size of the metal hose. The smaller the metal hose, the higher the pressure resistance. Three-point, two-point, one-point can withstand 300 kg pressure. One inch, six points, four points.

The maximum heat temperature of GB 8163 20 seamless steel pipe is 930 degrees. The operating temperature does not exceed 450 degrees.

Seamless steel pipes have a hollow cross-section, and are widely used as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe is lighter in weight when the bending and torsional strength is the same, and it is an economic cross-section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile drive shaft, bicycle rack and steel scaffolding used in building construction, etc., to manufacture annular parts with steel pipes, which can improve material utilization, simplify the manufacturing process, save materials and processing man-hours, and has been widely used to manufacture.

The 20 of No. 20 steel refers to the carbon content, and the carbon content is, which belongs to low-carbon steel. Steel can be divided into low carbon steel, medium carbon steel and high carbon steel.

Carbon content: low carbon steel is generally less than; Medium carbon steel is generally between; High-carbon steels are generally greater than.

In addition to containing carbon (C) elements and a certain amount of silicon (Si) for deoxidation, the steel does not contain other alloying elements (except for residual elements) except for manganese (mn) (generally not exceeding, higher alloying elements).

At present, this material does not exist in stainless steel, and the most high-temperature resistant is 310s (0cr25ni20), and the use temperature cannot exceed 1100 degrees continuously. The oxidation resistance of 310S stainless steel can be estimated by the chromium content. The alloy is resistant to high temperatures with a chromium content of at least 20%, therefore, 310S has quite good oxidation resistance.

The hydraulic pressure test is carried out on the stainless steel seamless pipe one by one, and it is maintained for no less than 5 seconds under the specified pressure value. The steel pipe shall not leak or leak, and the conventional supply water pressure test shall be p=2sr d (maximum not more than 20MPa). General intergranular corrosion resistance and excellent corrosion resistance to alkali solutions and most organic acids and inorganic acids also have a certain corrosion resistance, the stainless steel seamless pipes are tested for corrosion resistance according to the standard or the corrosion method agreed by both parties, and there shall be no intergranular corrosion tendency.

Extended information: The Rockwell hardness test of stainless steel pipes is the same as the Brinell hardness test, which is an indentation test method. The difference is that it measures the depth of the indentation.

The Rockwell hardness test is currently widely used, and HRC is second only to Brinell HB in the standard for steel pipes. The Rockwell hardness can be applied to the determination of very soft to very hard metal materials, it makes up for the difference of the Brinell method, it is easier than the Brinell method, and the hardness value can be read directly from the dial of the hardness machine. However, due to its small indentation, the hardness value is not as accurate as the Brinell method.

The high-temperature resistant hose is a kind of hose, which is generally used in the industrial production of potatoes, which we are relatively rare in life, and many people do not know much about it. High temperature resistant pipe hose has the characteristics of high temperature resistance, corrosion resistance, high toughness, etc., and is widely used in industry and life. Let's take a look at how about high-temperature resistant pipe hoses, as well as the characteristics and uses of high-temperature resistant pipe hoses.

1. How about the high-temperature resistant pipe hose.

1. The high-temperature resistant hose is also called the high-temperature silicone pipe, which is mainly used as wires, cables and wire terminals to provide insulation protection. The high-temperature resistant hose has the characteristics of high temperature shrinkage, soft flame retardant, insulation loss code and anti-corrosion, etc., and is widely used as insulation protection of various wire harnesses and anti-rust and anti-corrosion of metal pipes.

2. The high-temperature resistant hose has good flexibility, the bending radius is smaller than that of the general rubber hose, and the inner rubber layer is made of high-temperature and corrosion-resistant rubber, which is mainly used in the exhaust operation of chemical gas, hot gas and dust smoke, and can also be used for media containing solid particles.

3. The high-temperature resistant hose that has been flame retardant and fireproof treatment is more safe and reliable when transporting high-temperature medium, and the spiral steel wire skeleton rubber hose is an ideal choice for the exhaust operation of modern industrial chemical gas, hot gas and dust smoke.

Second, the characteristics of high-temperature resistant pipe hoses.

1. The high-temperature resistant pipe hose has high toughness, easy to bend, ultra-light, and good fluidity.

2. The high-temperature resistant pipe hose has very good resilience and good mechanical load resistance.

3. The durability of the high-temperature resistant pipe hose is good, high temperature resistance, high pressure resistance, and chemical corrosion resistance.

4. High temperature resistant pipe hose has good rolling resistance, and has a very small bending radius and temperature range.

5. The high-temperature resistant pipe hose products are beautiful and lightweight.

6. The high-temperature resistant pipe hose does not contain halogen, environmental protection and flame retardant, and is safe to use without hazard.

3. The use of high-temperature resistant pipe hoses.

The raw material of the high-temperature hose is a high-quality fiberglass-coated cloth supported by an inner copper-plated steel wire. High-temperature resistant pipe hoses are often used in glass factory tempering furnaces, coal mines, tunnels, subway projects, underground local press-in directional ventilation, and purification equipment to suction dust, exhaust gas, ash, etc. In addition to these industries, they are more common in our daily life and are more and more widely used in modern industry and daily life.

The metal hose is probably composed of three parts: corrugated hose, plastic mesh bag and coupling. Wear-resistant metal hoses are the core prefabricated components of modern equipment connection lines. For different application requirements, they are connected differently:

The three-part connection of corrugated hose, plastic mesh bag and joint is called connection; Industrial equipment clamping connections, known as industrial equipment clamping, also have the above two methods, called teaching. It is widely used in industrial equipment, chemical enterprises, petroleum, metallurgical industry, food industry and other industries.

Installation Method: Although the fluid density of the metal hose can also be stretched, if it is not installed in the right place, it will crack quickly and reduce the application period. It is widely used in industrial equipment, chemical enterprises, petroleum, metallurgical industry, food industry and other industries.

Wire hoses can be installed horizontally, vertically or at an angle. Ideally, it is installed vertically. In addition, installation in the vicinity should be avoided.

The baffle can be modified if necessary. Make sure that the metal hose has a considered indoor space for action to avoid the stress of the weld. The following is a specific talk about some important aspects of the hydraulic rotary joint required to be equipped with metal hoses (expression:

Describe the key components of the matter): The length of the metal hose is generally 500mm.

The heat resistance range of stainless steel metal hose is generally less than or equal to 450 degrees, please refer to Table 2 of GB T 14525-2010 "General Technical Conditions for Corrugated Metal Hoses" for details.

Metal hoses can withstand temperatures up to 600 degrees Celsius. The pressure resistance depends on the wall thickness and the size of the metal hose. The smaller the metal hose, the higher the pressure resistance.

Three-point, two-point, one-point can withstand 300 kg pressure. One inch, six points, four points can withstand 60 kg pressure; 1 inch 2 to 4 inches can generally withstand 25 kg of pressure. More than four inches is generally 16 kg of pressure.
