ZIBO KNC PETROLEUM EQUIPMENT
is the overseas authorized agency of SJ's FMC & SPM
high pressure fluid control products.

SJ Petroleum Machinery Co. , the largest manufacturer of high
pressure fluid control products in China, has established a
complete quality assurance system for design, development,
and manufacturing, based on the design and manufacturing
technologies introduced from SPM and FMC in the 1980s and our
own continuous innovations for over 20 years.

The manifolds will be designed and manufactured as per API 6A,
API 16C, API 5L, ANSI/ASME, and NACE MR0175. The manifolds are
featured by excellent working performance, good
interchangeability, high load-bearing capacity, high sealing
performance, and high reliability. All end connections are in
English system. They can be connected with international
products, meanwhile the prices are much lower.
High Pressure Fluid Control Products

We have designed and manufactured unions, plug valves, swivel
joints, check valve, safety valve, choke valve, gate valve, integral
connections, and straight pipes 12 families and 168 types of high
pressure fluid control products which are widely used for drilling,
cementing, logging, oil testing, acidizing/fracturing, coiled tubing
and sand control, and offshore high pressure fluid control operations.


Combination Maniflods

Recently, more than 100 different kinds of various high pressure
combination manifolds has been further developed, which are used
for drilling, cementing, test, fracturing, coiled tubing , sand control
operations and offshore operations, such as, choke and kill manifolds,
mud manifolds, stand pipe manifolds, hose loops, wax bead manifolds,
high & low pressure combination manifolds, and wellhead test device,
with nominal bore ranging from 2" to 5", pressure rating from 3000psi to
15000psi(21MPa to 105MPa). Meanwhile, we can supply various
custom-made manifolds.

We has already supplied hundreds of complete set of drilling mud
manifolds, choke & kill manifolds, BOP manifold system, and cementing
manifolds for offshore rigs, modular rigs, and 3000m~9000m land rigs.
These products enjoyed good reputation among customers.
HIGH PRESSURE FLUID CONTROL PRODUCTS CONTROL SYSTEM
Swivel joints, with integral ball bearing, are manufactured on the basis of technologies from FMC, USA. Various
models of swivel joints and their repair kits are available, suitable for normal or low temperature, or H2S
environments, with sizes ranging from 1" to 4" and rated WP ranging from 2000psi~20000psi(14MPa~140MPa).
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.
 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.
 All sizes of swivel joints can be interchanged with FMC equivalent products used in cementing and fracturing 
     equipment. 
 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. 
 Usually good lubrication can ensure that swivel joints work normally without much maintenance.
HIGH PRESSURE SWIVEL JOINTS
PLUG VALVE
Plug valves, forged of quality high strength alloy steel, are low torque valves based on the technologies introduced
from SPM. 1",2"and 3" plug valves with rated working pressure of 6000,10000,15000 psi(42,70,105MPa) are available.
They can work in normal temperature, low temperature or H2S environments.

SF42-3"×3" / SF70-3"×3" / SF105-3"×3" ; rated: 6,000psi(42MPa)~15,000psi(105MPa) .

 End connections of plug valves with sizes in English system may be union or male/female thread (LP,TBG), and they 
can be freely connected with products in international market;   Maintenance and repair of valve body can be 
done without removal, and no special tools are needed for removal;   The plugs have very good sealing 
performance;   Visible: There is a visible positioner where we can see if valve is open or closed. Brake spring will limit 
the position of valve;   3"hand wheel opener is suitable for opening in low temperature. Valves can be opened 
freely and flexibly.
Check valves are mainly used for high pressure applications and workover equipment. They are usually installed in high
pressure pipelines for preventing fluid flowing back. When fluid is pushed back, a retainer plate will automatically close.

Check valves, forged of high strength alloy steel based on US technologies, are fitted with unions on both ends for easy
dismantlement. The retainer plate inside sulfidized with Buna-N has a good sealing effect and a longer service life under
high pressure, for conventional or H2S environments.

CHECK VALVE
Safety valves are overpressure protection devices for protecting personnel and equipment, and usually installed in HP
operation line for cementing/fracturing pumps, pressure vessels and other equipment under HP and high
displacement. The preset pressure value ranging 5000psi to 15000psi(35MPa to 105MPa) is adjusted through the top
nut. When pumping pressure or operating pressure exceed the preset value, the safety valves will automatically open
for pressure release. While the pressure is less than the preset value, they will be automatically closed.

The model of safety valve available: AQF02-105 / AQF02-42 ; rated: 6,000psi(42MPa)~15,000psi(105MPa).
