18CrNiMo7-6 17-4PH Wellhead Tubing Head Tubing Spool Assembly
A forged casing head is a casing hanger that is manufactured through a forging process. Forging involves heating a piece of steel to a high temperature and then shaping it into the desired form by applying pressure with a mechanical press or hammer. Forged components are known for their strength and durability, making them suitable for the demanding conditions of the oil and gas industry, especially in high-pressure and high-temperature environments.
In summary, a forged tubing head is a robust and reliable component of a wellhead assembly used to support and seal casing strings in oil and gas wells, and it is manufactured through a forging process to ensure its strength and integrity.
18CrNiMo7-6 is a low-carbon, case-hardened (carburized) steel that is a special steel under the German standard (DIN) with a material number of 1.65871. This material is widely used in the manufacture of parts requiring high strength, wear resistance and fatigue resistance due to its excellent mechanical properties.
