API 9 5/8 '' Casing Cementing Head
The casing cement-head with double plugs (called as cement-head ) is a common cementing tool used as wellhead unit in all kinds of cementing operation. Comparing to cement-head with single plug, it owns longer cement-head body , and upper rubber plug and lower rubber plug can be put in at same time.
The tool owns some advantages such as simple construction, easy operation, high pressure resistant, manifold in common use, flexible in connecting. Especially, the lever type indicator can shows whether rubber plug goes through double plugs cement-head to enter casing so that operator can determine easily.
Not only common thread,also special thread cement head can be produced including NEW VAM,VAM TOP,FJ ETC.
Double plugs cementing head is special tool for pumping slurry and releasing plug.It can couple with two plugs simultaneously,and makes the drilling fluid fill into casing in turn and quickly.This can simplify the cementing operation, prevent cement pollution.
Features

It is manufactured utilizing API grade steels with API 8 round, buttress and premium threads.
Double balance pipe is developed.
Positive lever indicates plug releasing.
Main parts are made from AISI4145H alloy steel.
Top cover and union nut with large trapezoidial-threaded.
It makes the tool convenient to disassemble and carry.
