Thread Compliance: Standardizes threads according to ISO 7-1, covering sizes from
Design Symbols: Introduces "Design Symbol A" to denote the highest quality and most common configurations of fittings. Key Technical Specifications
Fittings manufactured under this standard must adhere to rigorous testing and design limits:
Pressure and Temperature: It outlines maximum working pressures and temperatures for general fluid transmission. For instance, every fitting is typically subjected to a leak test at a minimum air pressure of ), which is equivalent to a hydrostatic pressure of
Tolerances: It defines precise dimensions and wall thickness tolerances to ensure compatibility between different manufacturers.
Corrosion Protection: Most fittings are available in galvanized finishes to provide exceptional defense against rust and wear. Applications and Benefits
Malleable iron fittings are favored for their durability and "malleability"—their ability to withstand mechanical stress without cracking. Common applications include:
