Heritage: The Ming® brand derives its name from the famous Ming Dynasty which ruled China between 1368 and 1644. One of the greatest eras of orderly government and social stability in human history and is credited with major construction accomplishments such as the restoration of the Grand Canal, the Great Wall of China, one of the old seven wonders of the world, and the establishment of the renowned Forbidden City.
Our Ming® range are heavy duty hot dipped malleable iron fittings.Individual pressure testing on each fitting to ensure pinhole free quality.Each fitting is coated with a light oil to prevent corrosion on threads which conform to ISO 7-1 (BSP Standards) and ensure a prefect seal for the fittings lifespan.
Malleable iron is initially cast as white iron which, after casting, is subject to a lengthy annealing process which strengthens the cast iron. The annealing process consists of rapidly heating the casting to approximately 950⁰C, followed by a slow controlled cooling period. This annealing process distinguishes the product from non-malleable cast iron pipe fittings in micro structure and physical characteristics. Malleable fittings are stronger and less brittle than non-malleable cast iron fittings and are used where shock and vibration resistance is required and where fittings are subject to quick temperature.
