About black malleable pipe fittings

Black pipe fittings (black malleable iron fittings) are used to make connections to black iron pipe. Black iron pipe is used to transport natural and propane gas in residential applications. Black iron pipe is also most often use in fire sprinkler systems due to its high heat resistance and for water supply lines due to its resistance to water damage. Black fittings derive their name from the black oxide scale covering the surface.

Black malleable pipe fittings are different from galvanized or painted malleable pipe fittings. The surface of black malleable pipe fittings has not undergone any anti-rust treatment, so it presents the original black color of black malleable cast iron. When it comes to the size of black malleable pipe fittings, there are several concepts that you need to understand in advance:

  1. Product code: The product code of malleable pipe fittings not only has different codes for products of different shapes, but also has unique product codes for different sizes of products of the same shape. This unique product code is convenient for each code to correspond to a unique product under strict specifications.

  2. NPS and DN: It is common to identify pipes by inches using NPS or “Nominal Pipe Size“. NPS is often incorrectly called National Pipe Size, due to confusion with national pipe thread (NPT). The metric equivalent is called DN or “diametre nominel“.

  3. Weight. Divided into black product weight and galvanized weight. Obviously, the weight of malleable pipe fittings after galvanizing must be heavier than that of non-galvanized black pipe fittings. Of course, corresponding to different types of pipe fittings and sizes, there are different standards for the weight of pipe fittings.

  4. Package. This refers to how many pipe fittings of the same specification can be placed in a standard packing box. Of course, this is not definitive, and each company has different standards.
