Stainless steel elbows are used for the connection of pipe bends. Connect two pipes with the same nominal diameter to make the pipe bend at an angle. Divide carbon steel elbows, cast steel elbows, alloy steel elbows, stainless steel elbows, copper elbows, aluminum alloy elbows, etc. by material. The elbow can be said to cover the use of all walks of life, from the family to the enterprise. Each elbow has its own advantages and uses.
Stainless steel elbows of the pneumatic conveying main pipe are easy to wear. According to statistics, the service life of stainless steel elbows is 500-2000 times lower than that of straight pipes of stainless steel pipe fittings. The intensive wear of the elbow depends on the hydrodynamic characteristics of the powder air flow along the curved pipe. Generally speaking, the wear of the elbow is related to the speed of the conveying air, the abrasive performance and particle size composition, concentration, the material of the elbow itself, and the geometric size of the corners of the conveyed material. The relationship between the wear speed of the steel sheet and the impact angle at which the air stream containing steel chips meets it.
