Red Manifold Cementing Head For Oil Well Cementing Equipment

Cementing Head With Quick Change Adapter For Preventing Cement Pollution Cement Head High Pressure Manifold

Oilfield Cementing Equipment Single Or Double Plug Casing Cement Head, Manifold Cementing Head

Function:

Connect casing string and cementing manifold.

Features:

1. Quick-latch adapter is designed to offer easier, faster and safer makeup for two-stage cementing. It is manufactured utilizing API grade steels with connections for API 8 round, buttress and premium threads.

2. Double balance pipe is developed.

3. Positive lever indicates plug releasing.

4. Main parts are made from AISI 4145H alloy steel.

5. Top cover and union nut with large trapezoidial-threaded, it makes the tool convenient to disassemble and carry.

Not only common thread,also special thread cement head can be produced including JFE BEAR/ BOX 

Double plug cementing head

Heads capable of storing multiple plugs are preferred over those just carrying single plugs for operational convenience, as the use of more than one plug requires the opening of the head to insert a second (or even a third) plug after circulating the drilling fluid and launching the bottom plug. This allows not only the build-up of gels in the annulus, having an adverse effect on fluid displacement efficiency, but also cement-free fall. The risk of sticking the casing (pipe sticking) is also increased if reciprocation is stopped to allow the insertion of the additional plug (or two).

Cementing head is a manifold system that is installed on the top of the casing which allows the cement slurry to be pumped from the cement unit down any of the type of casing string. The cement head is also used for releasing the top and bottom cement plugs.

A “cement head” is screwed into the top casing collar or landing joint, depending on the type of casing cementing job. The discharge side of the downhole pump and the cement head are connected by a series of articulated or straight sections of high-pressure steel pipe, also known as “treating iron”
