The Advantages of the Full Welded Ball Valves

It is known that the valves used for the petroleum and natural gas transportation pipelines are usually the full welded ball valves, and it can be said that the full welded ball valves are the critical parts of the long-distance pipelines. With the development and progress of all aspects of our country, the demand for oil and natural gas is also increasing, which makes the requirements of the full welded ball valves applied to the petroleum and natural gas transportation pipelines more stringent.

The petroleum and natural gas belong to the flammable and explosive materials, and if they volatilize or leak, not only the energy will be wasted, but also the environment will be polluted. The flammable and explosive petroleum and natural gas may even bring some hidden hazards and trigger some potential accidents. Thus, besides owning the big power, the full welded ball valve should not only prevent the leakage of the media such as the natural gas, but also be quickly and accurately opened and closed.

At present, the full welded ball valves have wide applications in cities because of their superior quality, stable performance and long service lives which are hard to be owned by other types of valves. They are mainly applied to natural gas pipelines, central heating pipelines, heat exchangers, a variety of fluid pipelines, etc. 

The full welded ball valves are made from the seamless steel pipe by using the compression moulding and the integral automatic welding processes. There is no leakage happening on the central joints or the valve pocket joints, which makes the gaskets not needed any more and the installation costs reduced. The full welded ball valves can be designed with the anti-fire or the anti-static structure according to the customers' requirements, and they have a variety of connection combinations for special conditions.

The full welded ball valve can be buried directly under the ground, which makes the shallow valve well needed instead of the tall and big valve well, saving the space of the valve as well as the construction costs. The length of the full welded ball valve's stem can be adjusted according to the pipe design requirements. In addition, using the full welded ball valve can shorten the engineering time and effectively avoid the danger of the gas explosion. From the above perspectives, the full welded ball valve is a kind of valve product with the high reliability, which also displays the advantage of the full welded ball valve from anther perspective.
