Overview of Oil and Gas Pipeline Industry
China's pipeline transportation industry is an important industry that is indispensable to China's economic development and plays an increasingly important role in the country's economic construction. With the continuous acceleration of economic development, the market scale of China's pipeline transportation industry is also expanding. From the perspective of industry distribution, the oil and gas pipeline transportation industry occupies the vast majority, and its total turnover accounts for more than 80% of the total turnover of the entire industry. The second is the water pipeline transportation industry, which accounts for about 15% of the market revenue, and the remaining pipeline transportation industries account for a relatively small proportion of revenue.
Pipeline transport is a method of transporting liquids, gases, or semi-solid substances through pipes. This method of transport uses large pipe systems, usually made of metal or plastic, to connect the distance between supply stations and end users. Pipeline transport can be used for many different applications, including the transport of oil, gas, water, chemicals, and other types of fluids. In some applications, pipeline transport can provide an efficient, fast, and safe method of transporting goods while reducing environmental impact and costs.
Characteristics and technical status of domestic fully welded ball valves
The fully welded ball valve is actually a type of ball valve. Compared with ordinary ball valves, the fully welded ball valve seat is made of polytetrafluoroethylene hard sealing ring material and spring, so it has a strong ability to adapt to changes in pressure and temperature. The fully welded ball valve ensures that there will be no leakage within the marked pressure and temperature range. In general, the core components and design and manufacturing of domestic fully welded ball valves have basically achieved 100% localization, and the design and manufacturing level is at the international advanced level.
█ Features of fully welded ball valve
· The welded ball valve is pressed and formed by carbon steel seamless steel pipe. It is an integral welded ball valve, so it can be operated frequently in the presence of impurities and chemicals, and has a long service life.
· No maintenance, adjustment and lubrication are required, easy to install, and long-term reliable operation. The surface adopts plastic spraying treatment technology, the appearance is glossy and beautiful, and there is no leakage. The valve body adopts a welded structure, the valve is light and easy to insulate. At the same time, the adjustment mechanism is installed, which is very simple. The operating handle can also be removed and installed in reverse.
· The sealing material uses PTFE bevel elastic sealing ring on the spherical surface, so that the sealing effect reaches zero leakage and extends the service life.
· The fully welded ball valve adopts a fixed ball structure, and the valve can still ensure tightness even in the case of unstable pressure.
· The valve is light in weight, compact in structure, easy to insulate and easy to install. This valve can be installed horizontally or vertically.
· The valve stem of the fully welded ball valve adopts a leak-proof structure, using two "o" rings, so that the valve stem can rotate freely and seal tightly.
The valve stem of the welded one-piece ball valve can be lengthened.
