Principle and application of heating temperature of carbon steel elbow

2019-07-05 16:48:45

The heating temperature of carbon steel elbow is determined by the principle that the raw material austenitization temperature is above and the main compressive stress of the elbow wall is less than the yield of the data at this temperature. The higher the austenitization temperature, the higher the heating temperature; The higher the temperature of raw material, the higher the heating temperature. Medium frequency induction heating, WB36 steel temperature is 850 ~ 900℃, A335P22 steel 900 ~ 950℃, A335P91 raw material heating temperature point is 900 ~ 1000℃. The method of temperature measurement is the combination of stationary far-infrared thermometer and manual far-infrared thermometer. Temperature dispersion is an important technical parameter, which is directly controlled by the shape of induction coil and the orientation of induction coil relative to mandrel head. The shape of induction coil is the main factor, and the orientation of induction coil to mandrel head is not the factor. The radial distribution rule of temperature along mandrel head is low, medium and high. The heating temperature is high, the punching elbow wall thickness increases.

Carbon steel elbows are used for connecting pipe bends. Connect two pipes with the same nominal diameter to make the pipeline turn from the point of view. To distinguish the raw material carbon steel elbow, cast steel elbow, alloy steel elbow, stainless steel elbow, copper elbow, aluminum alloy bending number one. Elbow can be said to cover the use of all walks of life, from small families to large companies. Each carbon steel elbow has its own advantages and USES. Carbon steel elbow is a kind of connecting pipe fitting commonly used in pipe installation, which is used for connecting pipe bend. Carbon steel elbow can be favored by the market and constantly replace some of the traditional anti-wear data, the fundamental reason is that its excellent product quality, and in the traditional anti-wear data. Because these steels have better wear resistance and tolerance, the production technology is relatively simple, the induction economy is reasonable, and it is suitable for many working conditions, and it is welcomed by users. This also makes the use of thick wall wear - resistant elbow more widely, the cost is also more low.
