How much pressure can the stainless steel elbow bear

　　The smaller the diameter of the stainless steel elbow, the greater the pressure it bears, because it disperses the pressure per unit area. The pipes with the same wall thickness are all 6 mm thick elbows with an outer diameter of 114, and their working pressure is about 40KG. But in fact, their breaking pressure is more than 500KG. When the temperature of the medium is normal temperature, the elbow can be compressed only when it bears such a large pressure per square meter. But under the same thickness and temperature, when the outer diameter of the elbow is 219 and the thickness is 6 mm, its working pressure is about 25KG, and its actual breaking pressure is about 240KG. Why are the breaking pressures of the elbow with the same thickness different? The main reason is that the inner wall area of the elbow 219 is much larger than that of the elbow 114.

　　Temperature is also an important factor that affects the pressure resistance of stainless steel elbow. The working temperature of stainless steel elbow produced by us cannot exceed - 196 ℃~800 ℃, because with the increase of temperature, the pressure bearing capacity of the elbow becomes smaller and smaller, and the pressure bearing capacity will be much higher under low temperature conditions. If the temperature exceeds, the thickness of the elbow material must be increased to ensure the normal operation of stainless steel elbow.
