Today, the global oil and gas industry is growing slightly, and international energy is still dominated by fossil energy. The overall international oil price is rising, but the oil price is volatile and the oil supply is excessive. Global gas production and consumption are growing in tandem. Guided by policies, many developing countries, including China, have accelerated the construction of large-scale projects in the fields of oil refining, natural gas, coal, and chemical industry, and upgraded their overall production capacity. At the same time, the backward production capacity will inevitably be eliminated.
As the oil and gas industry speeds up the construction of large-scale projects, valves in the oil and gas industry will further develop in the direction of high-parameter large scale. With the strict control of equipment price by users, the localization process of key valves in the oil and gas industry will be further accelerated, and the valves with high sulfur content, high-pressure hydrogen flow, wear resistance and corrosion resistance, high-pressure oxygen and other harsh conditions will be fully localized, and users will put forward higher requirements for the long-term reliable operation of valves. With the continuous improvement of the environmental protection requirements of the international community, the microleakage of the valve will increase the higher requirements, the valve structure design without external leakage, the valve stem packing seal reliability will be more attention.
