China Drying News On November 29, China National Offshore Oil Equipment Manufacturing Co., Ltd. and the US Cameroon International Corporation signed a cooperation agreement in Beijing to jointly invest in the construction of a large and medium-sized all-welded high pressure ball valve joint venture project. This project will introduce world-leading ball valve technology, use Bohai Sea to equip the existing plant, invest and build a world-leading fully welded high pressure ball valve production line with an annual design capacity of 2,100 sets. This cooperation is the first cooperation between China's oil equipment manufacturing enterprises and the top companies in the international equipment manufacturing industry. The project is committed to manufacturing high-end pipeline ball valves, which is of great significance for improving the localization of China's pipeline ball valves, meeting the needs of high-quality pipeline ball valves for the construction of China's oil and gas pipelines, and ensuring the construction of national oil and gas pipelines. Li Xinhua, deputy general manager and member of the Party Group of CNPC, attended the signing ceremony and delivered a speech. He said that China Petroleum attaches great importance to the development of its petroleum equipment manufacturing business. The joint venture between the two parties to form a ball valve company is an important step in the implementation of the internationalization strategy of the China Petroleum Equipment Business, and it is also an important measure to improve the industrial chain of the pipeline business. It is hoped that the two parties will cooperate with each other and make joint efforts to promote the construction of large and medium-sized all-welded high-pressure ball valve joint venture projects, strive for early-sunrise products and create benefits, and look forward to the cooperation of the two parties starting from the project cooperation and continuing to expand cooperation in other fields. Jim White, vice president of Cameron International and President of the Valves and Metering Equipment Group, said that the joint venture project will benefit the business development of both parties in the long term. Cameron International will carry out joint venture projects in a safer and more effective manner to safeguard product quality and jointly support the continued growth of China's oil and gas industry with PetroChina. Cameron International is a world-renowned oil and gas equipment manufacturer and the world's strongest pipeline valve manufacturer. The company's all-welded high-pressure ball valve is recognized as the highest level of similar products in the world today, and has been successfully applied to key projects such as the West-East Gas Pipeline, the Second West-East Gas Pipeline, and the Shaanxi-Beijing Pipeline. After the joint venture project is put into operation, it will greatly increase the localization capacity of the pipeline ball valve, which can effectively reduce the import volume of similar products in the construction of domestic oil and gas pipelines.
Railway parts casting is one branch of Carbon Steel Precision Casting, which is widely used in railway markets. Precision Casting Of Railway Parts adopts lost wax casting, also called investment casting.
In wax pattern process,we mix stearic acid and paraffin wax. In wax pattern making, as you know, it is better than polyethylene, and the wax deformation is small. In dipping slurry process,most of the suppliers adopt water glass technics in domestic area,but we adopt compound technics or silica sol technics. As you know, Carbon Steel Castings will be much smoother with compound technics (compound of water glass and silica sol technics),this method is so popular with our customers, and the quality is higher than water glass technics, the cost is lower than silica sol technics.
In shell making,we adopt automatic sand-covering production line, which was invented under the guidance of our general manager.The indoor temperature was controlled by air-conditions,keeping the temperature at 24℃±1℃, which can make the castings much more stable,the internal tissues much more well-proportioned.
Our railway parts as precision casting products have quality assurance in accordance with ISO9001: 2008, strict material inspection and exact dimension control, with 100% quality control. OEM order is welcome. The parts can be made completely based on your specifications such as drawing, design, sample etc.
