Landing Ring
Description: A landing ring is a type of handling accessory that has one function in common with a welding collar. It supports the string of casing and screen during installation. Most contractors rely upon their personal experience but some of them prefer to use landing rings to construct very deep wells requiring an extremely heavy string of casing and screen. Commonly, landing rings are attached only to the upper joints of blank casing that bear the greatest the loads during the latter stages of well construction. Some contractors also prefer to use landing rings when handing large diameter casing (30, 26, 24, 20-inch diameter). There are no formal guidelines or specific parameters for the use of landing rings.
Features and Benefits
- Is appropriate for on-shore wellhead in order to prepare a balanced surface for welding.
Features and Benefits
- Seals the well bore while drilling out for surface
- Slip Lock diverter adapter can easily and quickly be removed after landing and cementing surface casing. The adapter can remain attached to the drilling riser system for subsequent
- Reduces installation time by eliminating the need for
- Available in 30”, 26”, 24”, 20 ”. Other sizes can be manufactured on request.
Casing Head Housing
Description: The casing head housing is the lowest part of the wellhead assembly and is almost always connected to the surface casing string. It supports subsequent drilling wellhead and completion equipment. Casing heads have a straight-bore bowl design that minimizes risk of damage to sealing areas by drilling tools, and prevents test-plug and bowl-protector wedging problems when pressure is applied. The design also reduces maintenance costs and enables suspension of heavy casing loads.
Casing Head Housing accepts Casing Hanger and Pack off assembly and can be furnished with female thread, slip-on weld and slip-on-lock lower connection. Standard outlets are LINE PIPE threads or API studded connection with optional VR threads.
