American Industrial Valve Group for the current gas pipeline technology, some of the shortcomings of a comprehensive analysis and development of a Waston pipeline valve - WastonB70 series of hard seal ball valve. The product fully solves the traditional product defects in gas transportation. American Industrial Valve Group on the natural gas pipeline technology summary: 1. The natural gas delivered by the pipeline contains a large amount of hydrogen sulfide XD pump (which is a very toxic and highly corrosive gas) before desulfurization. Even after natural gas desulfurization process, there is still residual hydrogen sulfide. Therefore, select the pipeline valve corrosion-resistant materials to be selected anti-sulfur. 2. Ordinary city gas pipelines are over a hundred kilometers long and can only be patrolled and inspected on a regular basis. Sometimes the pipelines need to go through complicated areas and the loss of media may lead to a serious fire accident. In particular, the pipeline from the city closer to prevent leakage of the valve is particularly important. 3. Once the pipeline is put into operation, it is not allowed to stop running within a few years, there is no interruption for a moment, and no overhaul period. Inline pipeline in the pipeline once the valve failure, the consequences could be disastrous. Therefore, the vulnerability of pipeline valves require long life. 4. Control personnel generally station or control room, requires a reliable valve control performance, and require the valve itself has protective and explosion-proof measures. In particular, the long opening of the valve requires a sudden change in circumstances, to be cut off accurately. So reliable control performance becomes a priority. AIVG for these conditions, the introduction of Waston pipeline valve - WastonB70 series of hard seal ball valve. Valve ball and the overall valve seat using rocket technology coated with chromium carbide and tungsten carbide coating. This will increase the surface hardness by nearly an order of magnitude better than conventional welding overlap reinforcement. High-strength Bellevilles spring pressure valve ball into the seat. This design addresses many of the issues that arise in the assembly and corrosion of trunnion bearings. And eliminates the ball and valve seat between the free gap. 2X-30A Unlike floating ball valves, AIVG's design eliminates the need for upstream pressure to provide a tight seal. Springs allow the valve to self-compensate and provide antistatic protection. WastonB70 Series Hard Seated Ball Valves use a one-piece seat rather than a free seat. The integral valve seat provides a solid platform on which the valve ball is subjected to high pressures, preventing the plugging of solids between the valve ball and the seat. When the valve ball is open, the valve seat from the media hazards. The integral valve seat also eliminates the possibility of leakage between the free valve seat and the valve body. WastonB70 series will be wearing parts of the life as a key point, the choice of anti-corrosion, high hardness, high fatigue strength, good stability of the material, and appropriate heat treatment, surface hardening and other steps to effectively improve the vulnerability of the valve life. For the control mechanism, AIVG emphasizes important parts such as signal input / output, communication, driving and so on. After rigorous matching, it can form a rigorous and stable system, which effectively resists the influence on pipeline control caused by severe working conditions such as cryogenic and violent heat. AIVG American Industrial Valves Group successfully owns a number of rotary vane Vacuum Pump performance of natural gas valves in the latest PetroChina Kazakhstan oil and gas pipelines and base stations in the successful application of WASTON natural gas series of valves.
