Ligtas na Koneksyon:
Ang mga thread coupling ay idinisenyo upang lumikha ng isang secure at mahigpit na koneksyon sa pagitan ng dalawang sinulid na tubo o mga kabit. Nagtatampok ang mga ito ng mga panloob na sinulid sa magkabilang dulo, na nagpapahintulot sa kanila na mag-screw papunta sa mga panlabas na thread ng mga tubo o mga kabit. Sa sandaling humigpit, ang pagkabit ay bumubuo ng isang matatag na kasukasuan na pumipigil sa pagtagas at sinisigurado ang daloy ng likido o gas nang walang pagkaantala.

Coupling Thread Types
In the world of piping and plumbing, coupling threads play an essential role in ensuring seamless connections between pipes. Different types of coupling threads are designed for specific applications, and comprehending these types can greatly enhance the functionality and performance of any piping system. One common variant is the 3-inch threaded coupling, which is widely used across various industries.
What are Coupling Threads?
Coupling threads refer to the helical grooves formed on the exterior of a coupling, which allow two pipes to be securely joined. The design and specifications of these threads can vary significantly based on the materials involved and the intended purpose of the connection. Understanding these variations is vital for selecting the right type of coupling for your project.
Types of Coupling Threads
There are several primary types of coupling threads, including NPT (National Pipe Thread), BSP (British Standard Pipe), and metric threads. Each type has distinct characteristics that make them suitable for different environments.
1. NPT Threads: National Pipe Tapered threads are commonly used in the United States. They have a taper that ensures a tightly sealed connection as the threads engage with one another. The 3-inch threaded coupling is often available in this thread type, which is ideal for applications requiring a strong gas or liquid seal.
2. BSP Threads: British Standard Pipe threads are widely used in the UK and other countries. These threads are designed with a different taper and are often found in water and gas lines. Like NPT, 3-inch BSP threaded couplings are also available, catering to various industry requirements.
3. Metric Threads: These threads are defined by their diameter in millimeters and are commonly used outside of North America. Thread specifications can vary, making it imperative to ensure compatibility when working with international piping systems.
