Pressure: less than that of general indoor low-pressure gas pipelines).

Bellows features:

1. To meet the personalized needs of users, a variety of installation methods such as buried wall, concealed application and surface installation are adopted.

2. Durable and permanent, the pipes and fittings are made of stainless steel SUS304 or SUS316L, and the pipe is covered with a protective sleeve to ensure a safe trial life of more than 70 years.

3. It has the ability to compensate for the gas leakage caused by the settlement of buildings and seasonal changes in weather (in 1995, the record of Kobe, Japan has shown the advantages of corrugated hose to prevent damage).

4. It is easy to install, can be cut and bent at will, and the internal flow rate remains unchanged, and it can bend and pass freely in a narrow space.

5. The pipe can be decorated first and then laid, which is convenient for the user to choose the time of pipe laying.

6. Increase safety, with optional length, there is no interface in the middle of the pipe body, and reducing the connection point is to eliminate gas leakage. Scope of application: Fluid:

Natural gas, artificial gas, petroleum liquefied gas, air mixture, biogas, etc. Pressure: less than that of general indoor low-pressure gas pipelines).

The application of metal bellows heat exchanger in the field of thermopower is mainly reflected by the boil-water and metal bellows cooler of thermal power plant. The steam from the thermal power plant is heated to a certain temperature through a metal bellows. Then the circulating water will be supplied to thousands of households to solve the problem of heating for residents in winter.

This kind of combined heat and power can not only save energy, but also improve the living environment of urban residents and achieve good social benefits.

Bellows: A kind of compression elastic element in pressure measuring instruments. It is a cylindrical, thin-walled, wrinkled shell with multiple transverse corrugations, and the bellows are elastic and can produce displacements under pressure, axial force, transverse force, or bending moment.

The bellows material is divided into rubber and metal. Bellows is a kind of regular wave-like pipe, and the bellows material is divided into rubber and metal. Commonly used metal bellows are carbon steel and stainless steel, as well as steel-lined, aluminum, etc.

It is mainly used for the connection between pipes and pipes, or the connection between pipes and equipment, when it is not convenient to install with fixed elbows, or when it is necessary to have a small bending radius, or irregular turns, expansion and contraction, or to absorb the thermal deformation of pipes.

Shengda plastic bellows are widely used in automotive wiring, machine tool machinery, automation instruments, motors, machinery manufacturing, electrical insulation protection, lighting equipment, automobile manufacturing, aviation equipment, subway, train, automation control and other industries.

So why are plastic bellows so popular in these industries?

The plastic bellows have light weight, strong pressure, excellent bending performance, easy construction, etc., and the plastic bellows have three materials: PE polyethylene, PA nylon, and PP polypropylene. Its corrosion resistance is far better than that of metal, it is not afraid of acid and alkali corrosion, it itself is not corroded, and can effectively protect the wires and cables and oil pipes in the pipe from corrosion. The plastic bellows can provide a barrier protection far superior to the metal bellows for wires and cables, and can prevent the pollution of harmful substances from penetrating the pipeline, so as to ensure that the post-tensioned prestressed structure has better durability; The plastic bellows have high strength, are not afraid of stepping on pressure, are not easy to be chiseled, its sealing performance and anti-leakage performance are high, the plastic bellows are not conductive, can prevent stray current corrosion, and the plastic bellows have better labor resistance, which can greatly improve the fatigue resistance of the components.

It is used as a measuring element of pressure measuring instruments to convert pressure into displacement or force, with long service life and convenient construction.

The bellows is used in the embedded project, which has the advantages of convenient connection and high hardness.

PA nylon hose (PA nylon 66), made of imported modified raw materials, is a high-tech product of bellows, high toughness, high impact resistance, good bending performance, high temperature resistance, bright surface, friction resistance, chemical corrosion resistance, flame retardant, electrical insulation" 200m, halogen-free environmental protection flame retardant, widely used in automotive wiring harness, electronic, mechanical wiring harness and other fields. PE plastic hose (PE polyethylene), black, other colors can be customized. The PP bellows is made of polypropylene material, the color is black, the color can be customized, the flexibility is good, the surface is shiny, and the chemical corrosion is resistant.

Answer: First, the use of bellows.

The main use of bellows is as a measuring element for pressure measuring instruments, converting pressure into displacement or force.

Second, a little bit of bellows.

1. The bellows pipe wall is thin.

2. The sensitivity of the bellows is high.

3. The measurement range of the bellows is tens of pascals to tens of megapascals.

3. Types of bellows.

Bellows mainly include metal bellows, corrugated expansion joints, corrugated heat exchange tubes, diaphragm boxes and metal hoses.

Metal bellows are mainly used to compensate for the thermal deformation of pipelines, shock absorption, absorption of pipeline settlement deformation, etc., and are widely used in petrochemical, instrumentation, aerospace, chemical industry, electric power, cement, metallurgy and other industries.

There are many companies and manufacturers that make bellows on the market. In the face of a large number of companies and manufacturers, we should give more priority to quality and product assurance when selecting and purchasing, and choose a satisfactory manufacturer.

1. Chemical resistance: not corroded by pollution, wastewater and chemicals, and not corroded by decaying substances in the soil;

2. Impact resistance: the pipe wall is used"u"The zigzag structure is impact-resistant, pressure-resistant, and does not break when the foundation sinks, and has strong resilience after deformation, and has good adaptability to the foundation;

3. Aging resistance: the pipe is usually black, which can withstand direct sunlight during storage and construction;

4. Cold resistance: the pipe will not be frozen and cracked, expanded and leaked in the -60 environment;

5. Light weight: easy to transport, convenient construction, is 1 8 of the weight of the cement pipe, and the buried pipe only needs an excavator, no large equipment;

6. Easy connection: the pipe can be connected outside the ditch first, and pushed into the ditch with an excavator to reduce the engineering time and cost;

7. Superior wear resistance: more wear-resistant than steel pipes and cement pipes, and strong transportation capacity of domestic water waste residue;

8. Superior drainage circulation: smooth inside, reduce friction, and fast drainage speed;

9. Economy: low cost of construction, management and maintenance;

10. Environmental impact: HDPE is a non-toxic raw material, harmless to the land and other environments, and can be reused.

11. Good stability of pipeline system: the circular external tensile structure of the pipe not only increases the ring stiffness of the pipe, but also has the effect of root resistance, which solves the tension and top well problems caused by the longitudinal displacement of the pipeline.

If you choose Tongyang, you will never be disappointed!
