ISO 1179 is the sealing standard for British Standard Pipe Parallel (BSPP) threads, with its BSPP external/internal thread design in accordance with ISO 228-1. The standard outlines four different sealing types to ensure connections are secure and leak-free. Understanding these parts is essential for making the right choice for various applications.
- Part 1: (ISO 1179-1)Thread Ports
- This part covers the basic thread ports, providing the fundamental specifications for the design and interaction of threaded connections.
- Part 2: (ISO 1179-2)Stud Ends with Elastomeric Sealing (Type E)
- This section outlines the standards for heavy-duty (S series) and light-duty (L series) stud ends that utilize elastomeric sealing (Type E). This type of sealing is known for its flexibility and ability to prevent leaks effectively.
- Part 3: (ISO 1179-3)Stud Ends with Sealing by O-Ring with Retaining Ring (Type G and H)
- Part 3 focuses on light-duty (L series) stud ends which are sealed by an O-ring with a retaining ring (Type G and H). This provides a robust seal, ensuring that the connection remains intact under various conditions.
- Part 4: (ISO 1179-4 which is called DIN 3852-02 under DIN standard)Stud Ends for General Use Only with Metal to Metal Sealing (Type B)
- The final part, Part 4, pertains to stud ends that are used generally and sealed metal to metal (Type B). This kind of seal is durable and suitable for a wide range of applications.
In summary, the ISO 1179 standard ensures the reliable and effective sealing of BSPP threaded connections, covering a variety of sealing types suitable for different situations and demands. Understanding these various parts and types allows for optimal selection and use in diverse applications, ensuring safety, efficiency, and durability in threaded connections.
