Product Details
FAC type grouting and circulation device is a wellhead tool for grouting and circulation when running casing. When the casing is lowered, the device performs real-time grouting; when circulation is required, the device can quickly circulate without installing a circulation head. The operating environment of the wellhead is improved, and the reliability of casing operation is improved.
By replacing the seal assembly can meet different sizes and pounds of casing, the maximum circulating pressure is 2500psi. The connection joint of FAC type grouting and circulation device for top drive is the standard 41/2IF drill pipe joint, but it can be adapted to top drive joints of other specifications through the conversion joint (it shall be specified in the order of special joints).

In principle, a sealant core corresponds to a casing of a specification and pound value, but as long as the inner diameter of the casing does not differ by more than 5mm, it can also be borrowed from each other. For example, 9.5/8-53.5 sealant core is applicable to 9.5/8 casing of single 53.5 (inner diameter 216.79) in principle, but it can also be applied to 9.5/8 casing of single 47 (inner diameter 220.5). Without special instructions, our company supplies the casing according to the above common specifications and wall thickness.
