Q235B steel plate and elbow are made of seamless steel tube with inner cavity spray welding cladding aluminum alloy layer. The Q235B steel plate produced by this processing technology has the following characteristics:
The processing technology is simple and the actual operation is convenient to make high yield.
Simple production and manufacturing, accurate specifications, good compaction. Q235B steel plate has symmetrical structure and stable characteristics. Not easy to appear, crack, vent and other conditions.
The thermal vibration resistance is good because the linear expansion coefficient of Q235B steel plate inside and on the surface is very, and it is not easy to rupture the inner layer and produce the initial invalid condition for the large change of the aspect ratio and the frequent change of the working conditions.
Q235B steel plate has high working pressure resistance: due to the selection of high-quality Q235B steel plate or high-quality thick steel plate, pressing and pushing system, after excellent welding, to promote the elbow above the working pressure of 10Kg/cm2, there is no problem, and it is not easy to appear the condition of the raw material water shield caused by partial leakage of steam.
