‘Not a small overall profit and loss’ is the whole business decisions, choices seal configuration, the principal conditions. Modern managers should be aware of a very sober, because the choice of seal leakage caused by the carelessness of enterprises brought about by the serious negative effects. Numerous bloody lessons not warn us all the time: a small seal by the careless use of the tremendous crisis, it is by no means the losses caused by its equal value, banbanmiaomiao are also immeasurable loss of raw materials, the cost of even the most precious human life losses.
Faced with so many different manufacturers, different performances, different specifications seal many customers are often helpless, not from trouble. Or because of a lack of accurate description ordering the result of unnecessary losses.In view of the above, we often encounter the problem
We recommend that you do in order to make full:
It is to provide samples of materials so that we measured size, provides the most accurate products.
Provide drawings or photographs, and annotated for the product name, material, shape and size requirements. For example, order pads: annotated gasket Name, Materials,size and working conditions. For example, the use of temperature, pressure and corrosive media, safeguarding working conditions, environmental requirements, the cost price. Information can be faxed to me, I may, in accordance with the status of the need for real-until the trial successfully.
In the use of the flange connecting pads, size not clear in the circumstances, must be confirmed flange in the form of docking: plane Flange, embossing Flange, tenon trough Flange. At the same time, recognition of this flange applies to any country and any standard.
How can the rational use, procurement seal?
Medium, temperature, pressure and working conditions should be the important factor.For example, in the little work pressure, the use of plastic flange docking circumstances,selection of hard texture seal,will be due to the improper selection of materials and leaked, and if the switch to graphite materials, will be flexible because of the special effects and achieve better results, and vice versa.
Again, the media work in the chemical environment, it must be reasonable match sealed different media to achieve good results, otherwise prone to unexpected chemical changes. Therefore, the choice of seal any contrary Miao will lead to disastrous consequences. General structure of the gasket following are available for reference：
1.Flanged connections for the Department for more than:
a.Plane gasket
b.spiral wound gasket
2. Pulling for rotating shaft sealing the use of various fillers;
3. Special parts for the sealing products. There are various common seal of the ball valve seat PTFE, graphite and rubber ring, and other pieces of Butterfly Circle. Caution should be taken when installing seal what? 1. Not to damage the sealing surface of the sealing surface or sealed Line
2. Be forced to install
3. Required for installation stresses balance, symmetry How to properly do not have temporary custody of the seals?
1. Anti-aging dark, moisture-proof, formation place, away from the cold and heat source; 2. Remain sealed not to put pressure on the natural relaxation of the state, not to change its external Oxfam physical shape; 3. Category 1 (the same shape, different material, the use of location, the application of the standards, stocking, date, etc.) |
