Stainless steel flanged ball valve, globe valve, gate valve when used, only for fully open or closed, do not allow to do flow regulation, so as to avoid sealing surface erosion, accelerated wear. Gate valves and upper screw globe valves have reverse sealing device, hand wheel to the top to the user's welcome.
When stainless steel flange is installed, the stainless steel flange can be directly installed on the pipeline according to the connection mode, and installed in accordance with the use position. Under normal circumstances, can be installed in any position of the pipeline, but need to facilitate the operation of the inspection, pay attention to the end of the stainless steel flange medium flow should be longitudinal disc downwards, stainless steel flange can only be installed horizontally. Stainless steel flange in the installation should pay attention to the sealing, to prevent leakage phenomenon, affect the normal operation of the pipeline.
Precautions for stainless steel flanges are as follows: long-term storage of stainless steel flanges, should be checked on schedule, often to the exposed processing surface must be kept clean, clean dirt, neatly stored in a dry and ventilated indoor place, it is strictly prohibited to heap or open storage. Stainless steel flanged ball valve, globe valve, gate valve when used, only for fully open or closed, do not allow to do flow regulation, so as to avoid sealing surface erosion, accelerated wear. Gate valve and screw globe valve inside the inverted sealing device, hand wheel to the top of the head surface for a long time will not rust, will not be corroded.

Stainless steel flange injection molding is an important method of plastic molding, which has been widely used in production. It has the following characteristics:
1. molding cycle is short, can be a complex shape, accurate size, with metal or non-metal insert plastic parts.
2. Strong adaptability to forming various plastics. At present, almost all thermoplastics except fluoroplastics can be molded in this way, and some thermosetting plastics can also be molded by injection molding.
3. high production efficiency, easy to realize automatic production.
4. Injection molding equipment is expensive, the mold structure is complex, and the manufacturing cost is high, so injection molding is especially suitable for mass production.
