SNJ was founded in 1991, specializing in making ball valves, butterfly valves &related actuators.The company is situated at a beautiful environment area inPudong Export
Processing Zone. It occupies 50 Mu landspace. The company integrates high-tech, intelligence andhumanism in its operation.The company owns modern machining & measuringequipments,
adopts modern information management,imports mature technology. It pays more attention on R & Dindependently. Most importantly, the humanism managementway makes the company develop
steadily & continuously.
Through the hard efforts of all the employees, rapid and big
changes have taken place in the Company since its
establishment in 1991. Today SNJ has established its leading
position in the Chinese valve industry. SNJ becomes the image
of the famous brand and enjoys a good reputation among the
customers.
SNJ has developed high-tech, value added products to satisfy
the changing market demand and has successfully marketed its
products in the world market. Efforts are also made to integrate
its resources to speed up its response to the market and
improve on time delivery with the aim to provide quality product
and service to the customers home and abroad.
The continuous development of the Chinese economy and
globalization tendency provide vast opportunity for SNJ's
development. High quality products have made us a significant
player in petrochemical, refinery, oil & gas transmission, district
heating, power plants and air separation industries.
To increase the core competence, SNJ has established itsinformation system which supports by advanced cloudtechnology and virtual server,
The information system canoperate in wire or wireless mode and connects top fromDecision Support System (DSS) down to process control of the CNC
machines and Manufacturing Executive System (MES).The information system such as ERP, CRM, OA , CAD/CAMintegrates all the business functions in sales, marketing,
purchasing, manufacturing, R&D, financing and daily officeroutines. The system enables the easy access of information inall business areas and makes it possible
to handle or inquirebusiness information almost at any time and at any place.
SNJ is equipped with modern CNC machines and machine
centre imported from USA, Japan, Korea & Roumania. Of
all the machines, 48” ball-matic machine is the unique one in
Chinese valve industry.
In addition to the above, the company imported advanced
measuring and machining equipments such as spectrometer,
CMM, multi-table work centre, large CNC lathe, ball matic CNC
machine centre as well as large drilling centre, which enhanced
the company's measuring and machining capabilities.
The company has got certificate of ISO 9001 International
Quality System in 1993, paying more attention on Total
Quality Control and attaining “zero defect”.
A more professional test lab was set up. Special devices and
instruments are used to obtain and record the actual test
parameters. Material test, product fire-tite test, low temperature
test, hot condition test and life cycle test can be performed in
accordance with various standards such as ISO, API, BS and
GB. The availability of the test lab has supported the
development of new product to ensure that the products we
offered are mature design, reliable and made-to-order.
The company has followed the modern manufacturing
executive system concept: the warehousing is arranged in
open racks, one product line is manufactured in one focus
factory including processes from manufacturing engineering,
purchasing, part machining to assembly and test. Such
arrangement has shortened the manufacturing lead time and
improved operation efficiency.
SNJ has introduced the design and manufacturing
technology of Double-Seal ball valves, high performance
Wafer-Sphere butterfly valves and Quadra-Powr X
spring/diaphgram actuators. It also adopts the advanced
manufacturing technology, develops fully welded ball valves
independently, which makes SNJ keep pace with international
level.
Fully welded body pipeline ball valve passed verification
and acceptance inspection by experts in 2006. Since then
SNJ started to manufacture fully welded body pipeline ball valve
for sizes under 32”. When the products were sold to the
markets well appraisals were received. SNJ invested CNC ball
turning and grinding machine, large pressure tester and
automatic submerged arc welding machine which well prepared
for the development of large size high pressure fully welded
body pipeline ball valves.
Under the combined coordination of National Energy
Administration Bureau, China National Petroleum
Corporation and China Mechanical Industry Federation, SNJ
singed a “Prototype Development Contract (40” & 48” Class
600Lb and Class 900Lb) with PetroChina West East Gas
Pipeline Company in November 2009. After a few month hard
work, 10 prototypes were made and passed verification and
acceptance inspection in July 2010 by the experts from the
above fields. The prototypes also passed simulation tests and
were used at customer sites for service verification. A new
contract was awarded after this to produce 31 pieces 48” class
900Lb valves for PetroChina and the valves will be used for the
third line of west gas transmission to east project, which broke
the monopolization in the large size high pressure fully welded
body pipeline ball valve market by the foreign supplier, and
returned the price of large size high pressure fully welded body
pipeline ball valve to the reasonable level. It is our contribution
to the strategy safety of China energy industry.
SNJ development of the G-series and the fully welded
ball valves has made it become a significant player in oil
and gas transmission markets in China. Products have widely
used on Sebei-Xining-Lanzhou pipeline, Lanzhou-ChengduChongqing
pipeline, Shanxi-Beijing Pipeline, Geermu-Lasa
pipeline and is the only successful bidder of the Chinese
domestic ball valves supplier in “West Gas to East Transmission
Pipeline”. Through SNJ’S global sales network, SNJ will
become a major supplier for worldwide oil & gas markets.
products have been widely used on many industries
such as Petro-chemical, district heating system, refining,
metallurgy, power plant and air separation. We have many
successful cooperation in many projects with CNPC, Sinopec,
CNOOC, Shenhua group, Shell, Secco, BASF, BP both home
and abroad.
