Different Types Of Casing Elevators And Their Uses

By Tammie Caldwell


Handling tools are of great importance especially in the oil drilling field. They have a number of uses among them suspending, moving and rotating tubular in and around the well center and on the drill floor. These tools vary from one another depending on the specific role they play, the amount of weight they can withstand among other factors. We take a look into types of casing elevators and their functions.

The single joint elevator is equally of importance. It is characterized by a housing with an access opening designed for receiving a tubular. It also comprises of a power assembly configured to open and also close the opening of the case. This type is used in handling a tubular alone and can handle up to a weight of five tones. In most cases, it is remote operated.

There exists the center latch type. Most of these are air operated. They are designed according to specification that will suit the condition of place in use and the exact functions. They fetch a number of uses and perform best when used to handle taper drill pipes, drilling tools such as drill collar in oil and gas fields among other uses.

Manufactures are in a position of availing the tubing slip elevator according to the specification given by a client and inconsideration of the budget. These types are mostly hoisting tools in the field. They are fit for integral joint tubing, non coupled casing just to mention but a few uses. It can also be used in place of a center latch to handle drill pipes, casing and tubing.

There is also the casing slip type. This type is also availed in different forms depending on the company behind the manufacturing process. They are handling tools on their own. They find uses in handling collar type covering. They come equipped with a safety latch lock to ensure safety in times of operations. The availability of different types of the same also determines how much weight they are in a position to handle while in use.

Another of the types is the hinged casing spiders and bushing. Like the others, it also finds a number of uses mostly in the handling field. There functions are defined by a number of determinants. These are used in place of cementing equipment where they are not in position to clear a closed spider rotary. They also differ according the weights they handle and can accommodate up to five hundred tones.

SLX elevators manufacturers have the obligation of ensuring that it is fully capable of performing the diverse roles it plays before marketing it for sale. It performs both the handling and suspending roles in the drill areas. It can therefore be used to handle the drill pipes effectively and at the same time lay them in the desired position and angle. It can withstand a weight of up to five hundred tones.

Drill type elevators also comprise the list. They consist of extensions with them that are in a position to provide substantial grip while in operation. Due to this feature, they are therefore suitable for handling purposes in the area of use.
