What is the application principle of SAE 37° Flared And NPT Adapters?

Zhejiang Tianxiang Machine Fittings Co., Ltd is located in the scenic Yuyao City, Zhejiang Province. This city is located on the south bank of the Hangzhou Bay Bridge. It is the golden intersection connecting the three major economic centers of Shanghai, Hangzhou and Ningbo. The company has a unique geographical location and a well-developed transportation network. Relying on this superior geographical environment, the company is not only convenient for the procurement of raw materials and the transportation of products, but also for its rapid response to market demand and the expansion of domestic and foreign business. Lay a solid foundation.

In complex industrial systems, the connection between different equipment and pipelines often faces many challenges. Due to differences in manufacturers, design standards, use environment and other factors, direct connection is often difficult to achieve or costly. The adapter becomes a bridge connecting different interfaces. Zhejiang Tianxiang Machine Fittings Co., Ltd uses a specific design to allow originally incompatible components to be closely combined to ensure smooth transmission of fluids. SAE 37° flared and NPT adapters play a vital role in oil, gas, water and other fluid transmission systems with their unique structural design and excellent sealing performance.

1. Structural features of SAE 37° flare and NPT adapter
SAE 37° flare design: SAE 37° flare is a pipe connection method widely used in hydraulic systems. "37°" refers to the flare angle, which is determined after careful calculation to achieve the best sealing effect and connection strength. During the manufacturing process, the end of the pipe will be processed into a tapered flare at a certain angle and a special flare joint will be installed. When the flare joint is tightly matched with the flared part of the pipe, the axial force generated by tightening the bolts or nuts causes the flared part to elastically deform, so that it fits tightly on the tapered inner surface of the joint to form a reliable seal.
NPT thread design: NPT is a standardized thread type used to connect pipes and valves. Unlike ordinary straight pipe threads, the tooth angle of NPT threads is 60° and it is a tapered thread, that is, the diameter of the thread gradually decreases from the root to the top. This design allows the NPT thread to generate a certain radial extrusion force when connected, thereby enhancing the sealing and stability of the connection. NPT threads also have good interchangeability and versatility, and are widely used in pipeline systems in the petroleum, chemical, natural gas and other industries.

2. Application principle of SAE 37° flare and NPT adapter
Sealing principle: The sealing principle of SAE 37° flare and NPT adapter mainly depends on the elastic deformation of the flare joint and the radial extrusion force of the NPT thread. When the flare joint is connected to the NPT thread adapter, the flare part is elastically deformed under the action of the axial force and fits tightly on the tapered inner surface of the adapter. The tapered design of the NPT thread generates radial extrusion force between the threads during the tightening process, which further enhances the sealing effect. This double sealing mechanism of Zhejiang Tianxiang Machine Fittings Co., Ltd ensures that the adapter can maintain stable sealing performance under different working conditions.
Connection principle: The connection principle of SAE 37° flare and NPT adapter is relatively simple and efficient. The end of the pipe is processed into a 37° flare that meets the requirements by special tools, the flare joint is installed on the flared part, and fastened by bolts or nuts. The conical inner surface of the flare joint fits tightly with the flared part of the pipe to form a preliminary connection. Then, the NPT thread adapter is screwed into the other end of the flare joint, and the conical design of the NPT thread and the radial extrusion force between the threads are used to achieve a tight connection with another section of the pipe or valve. This connection method designed by Zhejiang Tianxiang Machine Fittings Co., Ltd is not only easy and fast to operate, but also has high connection strength and good sealing performance.

IV. Application Fields
Application Fields: SAE 37° flare and NPT adapters produced by Zhejiang Tianxiang Machine Fittings Co., Ltd are widely used in many fields such as automobile manufacturing, aerospace, petrochemical, shipbuilding, food processing, etc. In automobile manufacturing, they are used to connect key components such as engine cooling systems, fuel systems, and hydraulic brake systems; in the petrochemical industry, they become an important bridge connecting pipes, valves, pumps and other equipment. With the continuous development of industrial automation, the application scope of SAE 37° flare and NPT adapters is still expanding.

5. Advantages Analysis
Excellent sealing performance: The double sealing mechanism ensures that the adapter can maintain stable sealing performance under different working conditions and effectively prevent fluid leakage.
High connection strength: The elastic deformation of the flared joint and the radial extrusion force of the NPT thread work together to make the connection more firm and reliable.
Easy operation: Zhejiang Tianxiang Machine Fittings Co., Ltd adopts standardized design and production processes to make the installation and removal of the adapter simple and quick.
Wide range of applications: Applicable to a variety of fluid transmission systems, including oil, gas, water and other media, to meet the needs of different industries.
