Introduce
 Stainless steel double conformity of needle valve manufacturer pipe fittings and welding pipe fittings products is indispensable in our daily life. Double the viega profi-press pipe fittings and welding pipe fittings products is indispensable in our daily life. Speaking of stainless steel pipe, a lot of people are familiar with their connection way, from the initial welding pipe fittings to the present technology upgrading, double the viega profi-press pipe is widely spread in recent years, integrating health and environmental protection, also promoted the development of the double the viega profi-press pipe fittings. It is, the hydraulic control system, the use of liquid pipeline system software, it is very common, its use is also much more special, to control traffic, work pressure and flow back to the, has a good practical effect. Because the actor bad of character of electric ball valves, safety factor of pipeline, and has great harm, so in the case of choosing 12 needle valve electric ball valve, must be in accordance with certain procedures and choose according to carry out.
2 and establish their own company of the specifications of the pipes, know how must choose specifications and interface mode of the electric ball valve. Three, on the basis of the pipeline must be, first to clear some of the commonly used pneumatic ball valve main parameters, such as the ability to work out, can allow the fluid density, seat hole the size of the size, the main parameters without right, the practical effects of the electric ball valve control traffic will be affected by the very large.
Pneumatic ball valve manufacturer
Four, according to the operating temperature of the pipeline, selecting suitable materials, natural, pipeline pressure, also want to consider in it.
The advantage of fixed ball valve
1, sealing emergency greasing rescue: because the material of seating dirt or fire accident cause unexpected null and void and greasing valve gives connected with note grease gun, save time and effort to lead sealing grease to the seating position, reduce the leakage.
2, on the valve stem seal and low actual operating torque: besides setting specification cast seal ring, filler screw cap on also set the "O" type sealing ring, two-way sealing to ensure the stability of the stem seal; Adding high purity graphite stuffing and sealing grease into to make the valve stem leakage after fire accident is very low. Rolling bearing and thrust bearing make gate valve stem practical light.
So, what is the difference between the double conformity of stainless steel pipe connection and welding?
1. In terms of 38 tube fitting the number, the number of stainless steel welded pipe and usage is much higher than stainless steel double viega profi-press pipe fittings. Welding pipe fittings of history is long, so now would be a big number, but I believe that in the near future, as the country's continuous development and progress, double the viega profi-press pipe fittings will be greatly increased.
2. In the aspect of environmental protection, in use process, because of the thin wall stainless steel double viega profi-press pipe adopts pressure welding method, do not need welding and argon arc welding, environmental friendly to the environment, must be argon arc welding, welding pipe fittings have pollution to the environment and the human body.
3. In terms of health, thin-walled double viega profi-press pipe adopts the advanced dual pressure connection technology, pollution-free therefore made pipes. However, the reason of welding pipe is argon arc welding and gas shielded or master technology is different. Some pipe fittings can produce welding pollution, water pollution water quality.
4. In terms of convenience, double the brass tube fitting viega profi-press pipe in the process of pressure is more and more convenient.
5. In the aspect of application, the application range of the welding pipe fittings than double the viega profi-press pipe application is wider, because welding is used for low pressure, medium pressure and high pressure, and thin-walled stainless steel pipe fittings can only be used for low pressure pipe fittings. |
