While drilling the oil well, surface pressure control is provided by a blowout preventer BOP. PSL 4 — Required Non-Destructive Testing Material NDE — Volumetric Examination As far as practical, the entire volume of each part shall be volumetrically inspected radiograph or ultrasonic after heat treatment for mechanical properties and prior to machining operations that limit effective interpretation of the results of the examination.
From Wikipedia, the free encyclopedia. Additionally, magnet-particle examination shall be performed by the wet fluorescent method. Offshore, where a wellhead is located on the production platform it is called a surface wellheadand if located beneath the water then it is referred to as a subsea wellhead or mudline wellhead. Material NDE — Surface Examination All accessible wetted surfaces and all accessible sealing surfaces of each finished part shall be examined by liquid-penetrant or magnetic-particle methods after final heat treatment and final machining operations.
They are used in conjunction with ring type seal gaskets.
If the pressure is not contained during drilling operations by the column of drilling fluidcasings, wellhead, and BOP, a well blowout could occur. The oil industry specifications for wellhead systems materials, dimensions, test procedures and pressure ratings etc. Additionally, magnetic particle examinations shall use the wet fluorescent method.

All provided information is only intended to be informative about the basic required NDE testing and does not include any Tensile, Impact, Dimensional, Traceability or Chemical Analysis testing that may be required per API 6A, 20 th All provided information is only intended to simplify the NDE requirements of API 6A, 20 th The code should be used when requesting or preforming inspections.
In exploration aapi that are later abandoned, the wellhead may be recovered for refurbishment and re-use.
Wellhead – Wikipedia
API 6A, 20 th Edition. Weld NDE — General The essential welding variables and equipment shall be monitored; welding activities shall be audited. Wellheads are typically welded onto the first string of casing, which has been cemented in place during drilling operations, to form an integral structure of the well. Views Read Edit View history.
Additionally, any magnet-particle examination shall be performed by the wet fluorescent method.
A wellhead is the component editiob the surface of an oil or gas well that provides the structural and pressure-containing interface for the drilling and production equipment. Loose connectors do not require hardness testing. In general well heads are five nominal ratings of wellheads: Some companies may require additional testing other than what is listed above.
For water well wellheads, see Puteal. Oil wells Oil platforms Petroleum production Oilfield terminology. The surface pressure control is provided by a Christmas treewhich is installed on top of the wellhead, with isolation valves and choke equipment to apk the flow of well fluids during production.

The primary purpose of a wellhead is to provide the suspension point and pressure seals for the casing strings that run from the bottom of the hole sections to the surface pressure control equipment. Wikimedia Commons has media related to Wellheads.
