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.

Programming With Couplings
A coupling is a mechanical device that connects two shafts together and transmits power. Its purpose is to join rotating equipment and allows some degree of end-movement or misalignment. There are many different types of couplings. It’s important to choose the right one for your application.
Mechanical connection between two shafts
There are many ways to achieve mechanical connection between two shafts, including the use of a coupling. One common type is the beam coupling, which is also known as a helical coupling. It is used for transmission of torque between two shafts. This type of connection accommodates axial, parallel and angular misalignments.
The hubs and shafts of a worm gear are connected together by a coupling. This mechanical connection allows one shaft to turn another without causing a mechanical failure. This type of coupling is made from sliding or rubbing parts to transfer torque. However, the coupling is not designed to withstand jerks, so it isn’t suitable for high-speed applications.
The use of a coupling is common in machinery and equipment. It helps transmit power from one drive shaft to the other, while adding mechanical flexibility. It is also useful for reducing the impact and vibration caused by misalignment. It also protects the drive shaft components from wear and tear.
A double-hook coupling can be used to provide a uniform angular velocity at the driven shaft. Another example is a double-jointed coupling. A double-jointed coupling can be used to connect shafts that are not directly intersecting. The double-jointed yoke can be used for the same purpose.
A shaft coupling is a device that maintains a strong mechanical connection between two shafts. It transfers motion from one shaft to another, at all loads and misalignments. Unlike a conventional linkage, a shaft coupling isn’t designed to allow relative motion between the two shafts. Couplings often serve several purposes in a machine, but their primary use is torque and power transmission.
Functions that control the flow of another function
One of the simplest programming constructs is a function that controls the flow of another function. A function can take an argument and return a different value, but it must be ready to return before it can pass that value to another function. To do this, you can use the goto statement and the if statement. Another way to control flow is to use a conditional statement.
Criteria for selecting a coupling
There are several important factors to consider when choosing the right coupling. One of the most important factors is coupling stiffness, which depends on the material used and the shape. The stiffness of a coupling determines its ability to resist elastic deformation. A stiff coupling is desirable for certain types of applications, but it’s undesirable for others. Stiffness can reduce the performance of a system if there’s too much inertia. To avoid this, ensure that the coupling you choose is within the recommended limits.
The size of a coupling is also important. Different coupling types can accommodate different shaft sizes and shapes. Some couplings have special features, such as braking and shear pin protection. When choosing a coupling, you should also consider the type of driven equipment. If you need to connect a high-torque motor, for example, you’ll want to choose a gear coupling. Likewise, a high-speed machine may require a disc coupling.
Another factor to consider when selecting a coupling is the torque rating. Despite its importance, it’s often underestimated. The torque rating is defined as the torque of the coupling divided by its OD. In some cases, torque may fluctuate during a cycle, requiring a coupling with a higher torque rating.
Torsionally flexible couplings are also important to consider. Their design should be able to withstand the torque required during operation, as well as the required speed. The coupling should also have a high degree of torsional stiffness, as well as damping. Furthermore, a damping coupling can reduce the energy wasted through vibration.
The sizing of a coupling is also determined by the torque. Many engineers use torque to select the correct coupling size, but they also take into consideration torsional flexibility and torsional stiffness. For example, a shaft may be able to handle large torque without damaging the coupling, while a disk may be unable to handle large amounts of torque.
Besides torque, another important consideration in coupling selection is the cost. While a coupling may be cheaper, it may be less reliable or easier to maintain. Couplings that are difficult to service may not last as long. They may also require frequent maintenance. If that’s the case, consider purchasing a coupling with a low service factor.
There are many different types of couplings. Some require additional lubrication throughout their lifetime, while others are 100% lubrication-free. An example of a 100% lubrication-free coupling is the RBI flexible coupling from CZPT. This type of coupling can significantly reduce your total cost of ownership.
In addition to the above-mentioned benefits, elastomeric couplings are low-cost and need little maintenance. While they are often cheaper than metallic couplings, they also have excellent shock absorption and vibration dampening properties. However, they are susceptible to high temperatures. Also, they are difficult to balance as an assembly, and have limited overload torque capacity.
