Valves

Gas and oil pipeline valves UK-based Global Oilfield Supplies Ltd supplies pipeline equipment to the world’s oil, gas and petrochemical industries, specialising in valves and gaskets as its main products.

covers all gate, globe, check and ball valves from sizes ¼" and above, rated ANSI 150, 300, 600, 800, 900, 1500 and 2500, with a variety of end connections including flanged RF and RTJ, butt weld, socket weld and screwed. These are available off-the- shelf in various grades of carbon, low carbon, stainless and chrome- moly steels, with an unlimited range of other material grades available on lead-time delivery.

As the company heads into its ninth year, it continues to grow by adding new stock lines and increasing existing ones to keep up to date with the market place. Utilising its stocks and dedicated factories it is able to supply a full range of pipeline valves on a stock based delivery, or on a longer lead time to suit the customer’s specific requirements. As a recent example, the company supplied two 30" gate valves to Exxon Mobil Europe for an unscheduled shutdown. After receiving the order on a Tuesday, the company carried out the client specific modifications required and delivered the valves via dedicated driver overnight on Friday; the valves were received on-site on Saturday morning and the line was up and running again by the evening. China Valves Technology, Inc, through its various subsidiaries, is engaged in the development, manufacturing and sale of high quality metal valves for the electricity, petroleum, chemical, water, gas and metallurgy industries. The company has announced that its gate and check valves used in the core island of nuclear power plants have successfully passed all tests administered by China Institute of Atomic Energy (CIAE), the primary nuclear science and technology research institute in China, and Nuclear Power Institute of China (NPIC), the leading base in China for nuclear reactor engineering research, design, testing and operation. With a diameter of 250mm and 1,500lb of compressive resistance, the prototype valves are among the largest and highest performing valves to be made by Chinese manufacturers. China Valves said that it has become the only valve manufacturer in China to pass all The Global Oilfield Supplies range

The company can accommodate the increasing requirements for bespoke valves and specials, and in some circumstances a bespoke valve can be designed, approved, manufactured and completed in as little as four weeks. Modification is also a key objective to meeting specific valve requirements when time is of the

Each nuclear power generating unit will require valves for an amount of more than RMB350mn at core inland, of which imports have traditionally accounted for the majority. “Following the successful tests, we believe we are well-positioned to win orders in the nuclear core island valve market,” commented Mr Jianbao Wang, chief executive officer of China Valves. “Meanwhile, we have continued tomake progress in supplying valves for the conventional island of nuclear power plants. In addition to nuclear valves, our strong competitive advantages include extra large diameter ball valves. We are the only company in China able to produce the large ball valves for pumped storage hydropower plants.”

tests provided by these two institutes at the first attempt, and the company is now eligible to supply valves for core islands of nuclear power plants, which are mostly imported from overseas. The valves underwent detailed tests, including functional tests and an earthquake test. The functional tests consist of a working life test which examines the valves resistance under 20 MPa high pressure at 38ºC, repeated 500 times, and under extreme temperatures in the range of 316ºC under pressure of 16 MPa, repeated 1,500 times, as well as impact tests under different temperatures, a high-pressure blocking test, a flow coefficient test and a pipe loading test. According to the National Development and Reform Commission (NDRC), China will install at least eight nuclear power generating units each year between 2010 and 2020, which require more than 30,000 valves for each unit, of which over
