ST double plugs casing cementing head

ST double plugs casing cementing head

The casing cementing head with double plugs (called as cementing-head) is a common cementing tool used as wellhead unit in all kinds of cementing operation. Comparing to cementing 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.

ST double plugs casing cementing head Feature:
  1. Quick-latch adapter is used to provide easier, faster and safer thread connection with API STC/LTC cementing casing.
  2. Simultaneously mounted rubber plugs, both used for conventional double-plug cementing, and for continuous two-stage cementing jobs.
  3. Indicator shows plug releasing.
  4. Balance pipe is developed.
