Fmc Swivel Joint for Drilling


The swivel joints are the common components in the well kill system and are manufactured for different kinds of liquids in the oil field.

These liquids contain the cement slurry, drilling mud, fracturing liquid, crude oil and treatment materials of grinding well.

Various kinds of joints can be matched flexibly and both ends can be connected by pipe thread and hammer unions.

These types of swivel joints provide the flexibility for the pipeline connection of well head, blowout preventer and other workover or well testing equipments.

1 Our chicksan swivel joints, with integral ball bearing, are manufactured on the basis of technologies

from FMC, USA.

2 Various models of swivel joints and their repair kits are available, suitable for normal or l

ow temperature, or H2S environments, with sizes ranging from 1″ to 4″ and rated WP

ranging from 2000psi~20000psi(14MPa~140MPa).

3 We can supply long and short radius swivel joints. Long radius swivel joints can minimize

fluid shock, and has better performance of resistance for scouring and erosion. We also need

to use short radius swivel joints for low pressure operation due to limited installation space.

4 Patterns of swivel joint are made in NC machine tools, with even wall thickness and

longer service life. Wall thickness difference of inner and outer arcs can meet FMC standard.
The three-ball-race design can bear heavy load stably, and ensure less vibration with

variable   load.
5 All sizes of swivel joints can be interchanged with FMC equivalent products used in cementing

and fracturing equipment.
6 Sealing parts made of synthetic rubber with release hole are fitted with blowout preventing

metal ring. When sealing parts leak, pressure will be automatically relieved. Safety performance

is enhanced.
7 Usually good lubrication can ensure that swivel joints work normally without much maintenance.
