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.
In order to achieve the working strength as required by the rated working pressure, all swivel joints adopt the low alloy steel and receive the thermal treatment, with the three raceways design. With a nitrogen surface treatment, the internal steel ball makes the rotation more flexible and much safer.
The multiple seal rings are placed in the connection, so as to prevent the foreign matters entering. When the seal elements have the leakage, the lubricating grease retainer with the automatic pressure reduction will prevent the pressure accumulating in the raceway cavity. The joints with several models of 2 inches to 3 inches can be selected. The maximum working pressure is 103.5 Mpa and the working temperature range is -29℃ - +82℃.

⑴. Swivel joint must confirm the rated working
pressure on the nameplate before use, applicable specifications, allowing the
use of the temperature range.
operator should take into account the drilling / or production operations will
feel the temperature of the device, select the appropriate temperature, and the
choice of the allowable temperature compatible Swivel joint.
Activities elbow have to undergo rigorous testing and nondestructive testing
hydrostatic pressure in the factory. Disassemble or repair, you must be
hydrostatically tested. Rated working pressure test pressure regulator 10
minutes, without leakage (Note: pressure test should be drained before the air
in the system).
Swivel joint should be regularly using ultrasonic thickness measurement of wall
thickness, it is recommended once a month, if not reach the effective thickness
value, should be replaced immediately. Replacement should be performed in
conjunction with other pipelines.
Swivel joint can not operate in continuous or frequent rotation swing working
condition; can not be immersed in water or working underwater. Can not
withstand axial load elbow work activities.
the installation Swivel joint, should fill seal grease, and manually check each
joint rotation is flexible, without jamming. Operators should wear goggles to
prevent the installation of a small debris flying eye injury.
Use Methods and Precautions
How to use:
all parts before use Swivel joint is flexible to use, it must be intact, in
line with criteria to use;
pressure to meet the requirements of the construction process, not up to
standard can not be used;
Swivel joint, adjusted to the desired angle and then hit with a pipe wrench to
tighten or tighten.
away after use to clean;
bearing oiling, rust-proof die.
⑴. Do not use in excess of the rated working pressure conditions.
joint design operating temperature of -46 ℃ ~ 121 ℃, when
the ambient temperature is below -46 ℃, or contact the fluid
temperature is higher than 121 ℃, you should immediately discontinue use.
not disassemble Swivel joint work in the system pressure.
joint less than the required thickness of the non-use, non-use of old and new
with Swivel joint.
⑴. Swivel joint during transport, non-collision, to avoid the rain.
joint should be stored in ventilated, dry place, not the sun and rain.
Forbidden contact with acid, alkali, salt and other corrosive substances.
⑴. Under normal conditions of storage and use, starting six months
from the date of shipment or product within three months, due to manufacturing
