The 2 section of the company covers an area of 20000 kilo meters and more than 200 employees. After 28 years of unremitting efforts with higher standards, the company has transformed from the original family workshop to a modern scale enterprise. The product line extends from the single copper refrigeration parts to a number of thousands of products, covering refrigeration,heating,machine fittings, water pipe fittings and valves etc. And strive to open up new areas and new channels to achieve the vision of pipe fittings leading enterprises
The company has formed 5 series of products: Copper capillary series, Copper pressfit series, AC copper pipe fittings, Valve, cards and thread brass fittings. All the series of product not only to meet the customer’s requirements for the national standard CJ/T-2000, the British standard BS864-2, the American Standard ASME B16.22-1995, the European standard EN1254-2 , but also to accept all kinds of non – standard fittings based on the special needs.
The products of ZheJiang n pipeline are certified by ISO9001 international quality system certification and AS 3688 Australia standard. The production process of raw materials inspection, raw material processing, annealing process, product quality inspection and finished packaging are strictly carried out according to Australian standards. Under constant demands and improvements, ZheJiang n has achieved the forefront of the industry in the following aspects.
Rw material control. First, each batch of raw materials must be supplied with certificate of qualification and material element certificate. In accordance with the supplier’s material sheet, the material is promptly notified to the responsible personnel of the material inspection, and the sample is inspecting. the unqualified raw materials will not be accepted. Second, the raw material, due to the change of the internal crystal after the forging process, we will test the rough after the forging in the lab. Third, because of the special use requirements of some products, such as the sealing product and the pressfit product, third times of stress need to be carried out, so the material composition is tested for third times. To ensure that the raw materials of the final product are qualified.
Annealing process is a important step in the processing of products. Better annealing process can greatly improve the durability and safety of products. Our annealing process is carried out in strict accordance with Australian standards, and the products are annealed at stages. For example, the crystal will change and reorganize when the brass material is heated to a certain temperature, so the temperature control is critical, and the dezine resistance of the material can not be damaged. The DZR brass (Dezincification resistance of brass) exported to Australia is strictly implemented in accordance with the Australian standards. Our annealing process can greatly improve the corrosion resistance and dezine resistance of the products. The product meets the requirements of environmental protection, and can be widely used in various sanitary products and direct drinking water projects, so as to ensure the pure and health of drinking water.
The quality control in the production process. First: the rough is checked by the inspector. The staff will measure the accuracy according to the drawing, and all the testing tools are imported from Australia. Second: inspectors carry out uninterrupted inspection of each product being produced. The packaging workshop tests the appearance and size of each product; third, the final product is checked, each product size must conform to the AS3688 drawing standard, and the quality inspection personnel record the product data of the test. In addition, for products that need to be tested for pressure, the inspectors will be able to test the airtightness or water tightness of each product professionally to ensure that each product reaches the pressure standard.
Finally, in the packaging, especially in the export, we use a more CZPT packaging, we use small boxes to pack the products, and then put small boxes in large boxes, double packing to ensure the safety of the product, reduce the transport process damage to the product.
First – class technology, advanced technology, perfect production process, precision testing equipment, every employee is in harmony with each other to highlight the spirit of ZheJiang n. “Quality first, pragmatic and enterprising, user foremost, CZPT to heart” is our company’s purpose. Stable quality and reasonable price are deeply trusted by domestic and overseas customers in the long term development.We will continue to innovate, improve and treat our customers with greater care.
The attitude determines the height, the details determine the success or failure, the above is the summary of the high standard of our production process, not only in the process, in the enterprise staff management, equipment management, warehousing logistics, financial accounting, office environment and other aspects of the high standards of their own. With the continuous self demand and promotion, our product quality will also give customers the perfect use of experience, to help customers win honor and reputation in the market, to realize the vision of the leading enterprise in the field of pipeline fittings.

Functions and Modifications of Couplings
A coupling is a mechanical device that connects two shafts and transmits power. Its main purpose is to join two rotating pieces of equipment together, and it can also be used to allow some end movement or misalignment. There are many different types of couplings, each serving a specific purpose.
Functions
Functions of coupling are useful tools to study the dynamical interaction of systems. These functions have a wide range of applications, ranging from electrochemical processes to climate processes. The research being conducted on these functions is highly interdisciplinary, and experts from different fields are contributing to this issue. As such, this issue will be of interest to scientists and engineers in many fields, including electrical engineering, physics, and mathematics.
To ensure the proper coupling of data, coupling software must perform many essential functions. These include time interpolation and timing, and data exchange between the appropriate nodes. It should also guarantee that the time step of each model is divisible by the data exchange interval. This will ensure that the data exchange occurs at the proper times.
In addition to transferring power, couplings are also used in machinery. In general, couplings are used to join two rotating pieces. However, they can also have other functions, including compensating for misalignment, dampening axial motion, and absorbing shock. These functions determine the coupling type required.
The coupling strength can also be varied. For example, the strength of the coupling can change from negative to positive. This can affect the mode splitting width. Additionally, coupling strength is affected by fabrication imperfections. The strength of coupling can be controlled with laser non-thermal oxidation and water micro-infiltration, but these methods have limitations and are not reversible. Thus, the precise control of coupling strength remains a major challenge.
Applications
Couplings transmit power from a driver to the driven piece of equipment. The driver can be an electric motor, steam turbine, gearbox, fan, or pump. A coupling is often the weak link in a pump assembly, but replacing it is less expensive than replacing a sheared shaft.
Coupling functions have wide applications, including biomedical and electrical engineering. In this book, we review some of the most important developments and applications of coupling functions in these fields. We also discuss the future of the field and the implications of these discoveries. This is a comprehensive review of recent advances in coupling functions, and will help guide future research.
Adaptable couplings are another type of coupling. They are made up of a male and female spline in a polymeric material. They can be mounted using traditional keys, keyways, or taper bushings. For applications that require reversal, however, keyless couplings are preferable. Consider your process speed, maximum load capacity, and torque when choosing an adaptable coupling.
Coupling reactions are also used to make pharmaceutical products. These chemical reactions usually involve the joining of two chemical species. In most cases, a metal catalyst is used. The Ullmann reaction, for instance, is an important example of a hetero-coupling reaction. This reaction involves an organic halide with an organometallic compound. The result is a compound with the general formula R-M-R. Another important coupling reaction involves the Suzuki coupling, which unites two chemical species.
In engineering, couplings are mechanical devices that connect two shafts. Couplings are important because they enable the power to be transmitted from one end to the other without allowing a shaft to separate during operation. They also reduce maintenance time. Proper selection, installation, and maintenance, will reduce the amount of time needed to repair a coupling.
Maintenance
Maintenance of couplings is an important part of the lifecycle of your equipment. It’s important to ensure proper alignment and lubrication to keep them running smoothly. Inspecting your equipment for signs of wear can help you identify problems before they cause downtime. For instance, improper alignment can lead to uneven wear of the coupling’s hubs and grids. It can also cause the coupling to bind when you rotate the shaft manually. Proper maintenance will extend the life of your coupling.
Couplings should be inspected frequently and thoroughly. Inspections should go beyond alignment checks to identify problems and recommend appropriate repairs or replacements. Proper lubrication is important to protect the coupling from damage and can be easily identified using thermography or vibration analysis. In addition to lubrication, a coupling that lacks lubrication may require gaskets or sealing rings.
Proper maintenance of couplings will extend the life of the coupling by minimizing the likelihood of breakdowns. Proper maintenance will help you save money and time on repairs. A well-maintained coupling can be a valuable asset for your equipment and can increase productivity. By following the recommendations provided by your manufacturer, you can make sure your equipment is operating at peak performance.
Proper alignment and maintenance are critical for flexible couplings. Proper coupling alignment will maximize the life of your equipment. If you have a poorly aligned coupling, it may cause other components to fail. In some cases, this could result in costly downtime and increased costs for the company.
Proper maintenance of couplings should be done regularly to minimize costs and prevent downtime. Performing periodic inspections and lubrication will help you keep your equipment in top working order. In addition to the alignment and lubrication, you should also inspect the inside components for wear and alignment issues. If your coupling’s lubrication is not sufficient, it may lead to hardening and cracking. In addition, it’s possible to develop leaks that could cause damage.
Modifications
The aim of this paper is to investigate the effects of coupling modifications. It shows that such modifications can adversely affect the performance of the coupling mechanism. Moreover, the modifications can be predicted using chemical physics methods. The results presented here are not exhaustive and further research is needed to understand the effects of such coupling modifications.
The modifications to coupling involve nonlinear structural modifications. Four examples of such modifications are presented. Each is illustrated with example applications. Then, the results are verified through experimental and simulated case studies. The proposed methods are applicable to large and complex structures. They are applicable to a variety of engineering systems, including nonlinear systems.
