ASTM A860 WPHY 42 Fittings are made up of a grade of steel that is intended for construction in wrought carbon steel and alloy steel. These could be seamless or welded fittings. They are applied in high temperature services under high pressures. These pipe fittings could range from ½ inches to 48 inches in nominal bore size. There are different schedules of these pipes indicating their pressure range, wall thickness and diameter as well.
ASTM A860 WPHY 42 Fittings
The different types are for different functions in a piping system. The MSS SP-75 WPHY 42 Elbow is used for high pressure high temperature applications where the pipeline has to be turned to a desired angle tolerating the angular momentum and impact of the change of direction. There are different types of elbows to use in appropriate conditions such as short radius, long radius, 45 degree and 90 degree elbows. The API 5L X42 Fittings have to be made NACE compliant.
The ASTM A860 Grade wphy 42 Tee is one of the commonly used fitting to branch off a pipe into two or to merge two pipelines into one. The A860 Gr wphy 42 Buttweld Fittings are stronger and are used in heavy welding applications. The WPHY 42 material has a composition of manganese, phosphorous, sulfur, silicon, nickel, chromium, molybdenum and copper.

Process of Manufacturing
Push, Press, Cast, Forge.
Chemical Structure of API 5L X42 Fittings
WPHY 42 Fittings Surface treatment
This process includes coating its surface with rust proof transparent oil or back oil or they could also be hot galvanized. The resistance to corrosion is improved due to API 5L X42 Fittings Surface treatment.
