The Eleventh Five-Year Plan has passed, and the pipe fittings industry has ushered in the Twelfth Five-Year Plan. There are many problems facing the metal hose equipment industry. So in the 12th Five-Year Plan, what is the biggest problem that the industry urgently needs to solve? Pipe Fittings believes that it is a talent problem. This is also a common problem in our metal hose equipment industry and even the entire machinery industry.

High-quality pioneering technicians and skilled craftsmen are what the industry lacks. Technicians,OEM Hydraulic Fitting skilled workers, and managers are the three cornerstones that support the survival of an enterprise, and none of them are indispensable. In our company, there is a general shortage of the three types of talents, which softens the foundation for the survival of the company.

As far as enterprises are concerned, market expansion depends on products, product development depends on talents, and talent development depends on the environment (policies and treatments). In this chain, people are the first. There is a market for the product. In enterprises in developed countries, the educational level of blue-collar employees is shrinking year by year, and the quality of blue-collar employees is generally improving. In our country, how many of the undergraduate or junior college graduates go to operate machine tools?

Although some companies clearly stipulate that a certain degree of education is set up as a worker's post, how many people can be put into the post or stay in the post for long-term dedication? For the development and survival of the enterprise, the metal hose equipment industry continues to absorb college graduates with a not-so-small salary under difficult conditions to enrich the team of technical personnel and the continuation of the enterprise.

However, among college graduates after the expansion of enrollment, the overall quality is generally low, more than salaries, less than dedication, more than oral, and less practical. A computer and a foreign language are all his studies. 

Timely installation deviation and avoid secondary disasters caused by damage to tanks and pipelines in the event of an earthquake. The central drainage metal hose of the floating roof of the storage tank is used to remove the rain, snow and other sundries on the floating roof of the storage tank, instead of the original rotary joint foldable drainage pipe and the central drainage hose of the inlet. 

Metal hoses are used in petrochemical docks. The use of vacuum jacketed hoses can effectively solve the transportation of low-temperature media. The use of metal hoses in the long-distance transportation pipelines of the fixed trestle bridge mainly compensates for the thermal expansion and contraction of the transportation pipeline, compensation for the settlement of the fixed trestle bridge and the shore end foundation and the deviation of construction and installation.

Metal hoses are installed between the fixed approach bridge and the mobile approach bridge,industrial hydraulic fitting and between the mobile approach bridge and the barge to effectively compensate for the displacement caused by the fluctuation of the river (sea) surface and the movement of the barge caused by the river (sea) waves. Metal hose joints are used as soft connections between oil tankers and other chemical transport ships and the wharf. 

Metal hoses are used in piping for chemical equipment. Stainless steel metal hoses have the advantages of corrosion resistance and high temperature resistance and are widely used in chemical equipment.

Metal hoses are used in transportation and filling systems. Metal hose joints are used as trains and automobile tanks. The soft connection of tank filling oil or other liquid loading and unloading device. It has the advantages of soft tube body, small bending radius, strong torsion resistance, long life, safety and reliability.

This can effectively ensure the quality of the hose joint and ensure the stability of its quality in the pipeline. ; In addition, the size and finish accuracy of the sealing surface of the connecting part of the hose joint should be carefully checked. When assembling, pay attention to not being damaged. We hope that the majority of manufacturers and construction units will pay attention to it.

The above is the quality inspection work that the metal hose joint manufacturer needs to do before leaving the factory. Welding causes the wire mesh sleeve to pull. Due to the quality of the welding, the bellows, ring and steel wire mesh sleeve will cause part of the steel wire to be welded (overburned or unwelded) during the trinity welding process. In order to prevent this from happening, the quality of welding should be improved.

The mesh sleeve of the welding part of the tube trinity or other parts is broken, which will cause the outer drum of the corrugated tube to be stretched and damaged, causing medium leakage. The hose should be tested for water pressure and air tightness before leaving the factory, and only after it is qualified can it leave the factory. In this way, after the hose is installed in the pipeline, due to the uneven force of the steel wire, under the action of the medium pressure, the steel wire at the virtual weld is pulled off first, so that the entire steel wire mesh sleeve is pulled off, causing the outer drum of the corrugated pipe to fail and cause danger.

Improper installation, causing the wire mesh to break. In the installation process of the hose, due to improper installation or excessive pressure, the hose will be stretched and twisted. Therefore, the design and selection should be accurate, and the installation should be correct.. When the stress generated by the stretch or twist exceeds the ultimate strength of the hose wire mesh sleeve, it will become soft.

The mesh sleeve is wrapped around the corrugated pipe, and the two ends are welded with the corrugated pipe, the JIC Pipe Fittings Manufacturers end ring and the metal hose joint.The stainless steel wire mesh sleeve in the metal hose mainly protects the bellows and bears the medium pressure (mainly axial force) in the bellows

One of the most important characteristics is the elasticity of plastic coated metal hoses, which may not be very familiar to customers who do not know much about them. The elastic properties of plastic-coated metal hoses The elastic properties of plastic-coated metal hoses refer to the relationship between the displacement of a metal bellows and other elastic elements on a specified cooking load and the load.

What are we from below? Speaking of the elastic properties of plastic-coated hoses. If remanufactured products can really meet the performance indicators of new products, it seems not OEM hydraulic ferrule difficult for customers to accept them. Now many domestic experts have begun to develop different pipe fitting products, which are used in different fields because of their different properties..

Different types of hose pipe fittings can be used in different fields of automation industry at the same time, which greatly promotes The progress of the domestic automation industry. Because it not only combines some of the high-quality performance of all contemporary pipe fittings, but also can be divided into more types. Anyone who has used plastic-coated metal hoses will surely be shocked by the excellent performance of this kind of hose products.

We know that the application of these galvanized pipe fittings is quite common, so it can be said that the development of science and technology is unquestionable, and with the emergence of more and more types of pipe fittings, it is not difficult to find this kind of plastic coated metal soft

The pipe fittings are the most dominant. Because plastic-coated metal hoses can withstand high temperatures and have good pressure resistance in addition to inheriting the hardness of metals, they are used by many companies to lay some industrial pipelines

Once the process media indicators related to corrosion hydraulic hose fitting change, such as the increase of electrical conductivity, the decrease of pH value, etc. How to take effective measures to remedy it in time may cause serial production and safety problems. After commissioning, strengthen the inspection of the metal hose joints in important parts, pay close attention to the changes of the process medium.

To minimize the impact on production and safety. When leakage of stainless steel metal hose joints is discovered, it is recommended to take the following measures in time to remediate: After long-term wear and tear, leakage may occur. Before selecting the model, the designer needs to understand the condition of the medium flowing through the metal hose, including the composition and corrosiveness of the medium, correctly select the parts and materials of the flowing part, and put forward the corresponding technical requirements to avoid the occurrence of galvanic corrosion.

The editor puts forward the following suggestions to the staff: There is no exception for stainless steel metal hose joints. Preventive measures to avoid leakage of metal hose joints: In order to allow the metal hose to function normally during use, in addition to timely remedial measures when a leak is found, precautions must be strengthened before this to avoid leakage as much as possible. Before adjusting the installation position of the original gate valve on the tank to the metal hose, once the metal hose has a problem, the valve can be cut off to avoid a large amount of leakage of the medium in the tank; at the same time, even if the metal hose joint leaks again, it is convenient to quickly replace it..

Any product has a service life and a shelf life. Replace all parts and materials that have been in contact with the medium, including flanges, metal joints, etc. Replace the metal hoses at the outlets of all synthetic water tanks; it should be confirmed in time Whether the metal hoses and joints can meet the existing technological requirements, and necessary preventive measures should be taken in time

With the closure of edge metal hose joint factories, many customers have to find new metal hose joint factories, so those surviving metal hose joint factories have increased their sales and demonstrated their value to new customers. 　　

What causes the fracture of the joint? What should be paid attention to to avoid joint accidents? How to obtain evidence in case of problems? Through what channels do you protect your rights? The quality of identification can be obtained according to the standard It is understood that it is still difficult to distinguish the root Thread Joint cause of the joint fracture. It is understood that the service life of general joints is 200,000 times and should be replaced after long-term use.

The production of pipe joints caused problems in the quality of the products.. According to reports, many inexperienced construction workers over-tightened the hose joint interface during the installation process, causing cracks in the inner substance of the joint, but the outer glaze is not easy to find, which will bury hidden dangers for future use.Due to the different internal materials of metal hose joints on the market, the quality is uneven, and it is difficult for consumers to distinguish the quality of the joints from the appearance.

It is understood that the quality of the joints and hoses is not good enough, and the material, wall thickness and other problems make the strength performance and sealing performance of the metal hose joints not up to the standard. If the content of the standard is not met, it is a quality problem and can be used as strong evidence for prosecution. Use and maintenance can not be ignored Long-term use of metal hose joints at home generally does not cause people's concern, but frequent use and improper maintenance also bury hidden dangers to the joints to a certain extent.
