slip on flange also known as lap welding flange.The connection between the flat welding flange and the pipe is to insert the
pipe into the flange hole to the appropriate position first, then lap welding, its advantage is easier to weld the assembly, and
the price is cheap, so it has been widely used.According to the internal pressure calculation, the strength of the flat welding
flange is about two-thirds of the corresponding butt welding flange, fatigue life is about one-third of the butt welding flange.
Therefore, flat welding flange is only suitable for the low pressure class, pressure fluctuation, vibration and vibration are not
serious in the pipeline system.Flat welding flange and can be subdivided into belt neck flat welding and plate flat welding two. welding neck flange also known as high neck flange, it is different from Other flanges from the flange and pipe welding to flange
has a long and inclined high neck, the wall thickness of this section of high neck along the direction of the height of the gradual transition to the thickness of the wall of the pipe, improve the pressure of the discontinuity, thus increasing the flange
strength.Butt welding flanges are mainly used in severe working conditions, such as pipe thermal expansion or other loads and the
flange is subjected to greater pressure or pressure changes repeatedly;The pressure, the temperature fluctuates greatly the
pipeline or the high temperature, the high pressure and the below zero low temperature pipeline. Product display product comparison Application Because flange has good comprehensive performance, so it is widely used in chemical engineering, construction, water supply, drainage, oil, heavy and heavy industry, refrigeration, sanitation, plumbing, fire, electricity, aerospace, shipbuilding and other basic engineering.
